The INT Medical Inflation Device is used during interventional procedures to inflate and deflate a dilatation balloon under controlled pressure. Three references are offered. AI30 and AI40 carry analogue gauges and are rated for no leakage under 30 and 40 atmospheres. INT-IDA-233 carries a digital gauge and is rated to 30 atmospheres. All three hold 20 mL. Each device pairs a syringe barrel with a threaded plunger and a locking handle. The operator turns the handle to raise pressure, then releases it to deflate.

An ergonomic handle profile is used to keep the force required manageable at higher pressures. A 30 cm high-pressure extension tube connects the device to the balloon catheter. It ends in a male rotating luer. The connection tightens without twisting the tube. That helps hold pressure through the inflation. A 3-way stopcock is included and rated up to 500 psi. The stopcock lets the operator switch between the balloon line, the contrast source, and a closed position without disconnecting anything. Gauge choice is the main decision between references.

An analogue dial is familiar and needs no power. A digital display shows the pressure as a number. That removes the reading errors that come with a needle and a printed scale. These are single-use devices. The GMDN classification is term 17541, covering single-use catheter balloon inflators. They are not made to be cleaned and used again.

Medigear.uk supplies all three references to UK catheter laboratories. Sterilisation method, shelf life, box quantities, and UK conformity status are confirmed before order.

Balloon angioplasty is the main setting for this device. A dilatation balloon is passed into a narrowed vessel and inflated to open it. The inflation device supplies the pressure and shows what has been reached. Pressure matters clinically. Too little and the lesion is not fully dilated. Too much and the vessel wall or the balloon itself can be damaged. Every balloon carries a rated burst pressure. The operator stays below it while reaching the pressure the lesion needs. An accurate gauge is therefore part of the safety case. It is not just a convenience.

Balloon-expandable stent deployment uses the same equipment. The stent is mounted on a balloon and expanded to appose the vessel wall. Post-dilatation to improve stent apposition often needs higher pressures. That is where the 40 atmosphere AI40 reference fits. Drug-coated balloon work adds a timing element. The balloon is held inflated for a set period so the drug transfers. INT describes a timer function on its digital inflation devices for this purpose. Peripheral interventional radiology uses the same device class for arterial and venous work outside the coronary tree.

Vessel calibre and balloon size differ there, but the inflation principle and the pressure limits are the same. The 3-way stopcock supports the practical workflow. An operator can draw contrast, purge air, and isolate the balloon line without breaking a connection. Air in the system is a genuine hazard during balloon inflation, so purging matters. These are single-use devices and must not be reprocessed.

Medigear.uk supplies the instructions for use with every order so clinical teams can confirm handling before a case.

Two Pressure Ratings Within One Product Family

AI30 and AI40 let a service match the device rating to the balloons it stocks, without changing supplier or retraining staff on a different handle.

Analogue and Digital Gauge Options

Laboratories can standardise on a familiar dial or move to a numeric display, drawing on the same device platform and consumable relationship.

Digital Reading Removes Interpolation Error

A numeric display avoids the judgement involved in reading a needle between printed graduations, which matters when working close to a balloon's rated pressure.

Male Rotating Luer on the Extension Tubing

The connection tightens without twisting the tube, which helps maintain the seal and keeps pressure stable through an inflation.

30 cm High-Pressure Extension Tubing

The stated length gives working separation between the device and the catheter hub without introducing the extra compliance a longer line adds.

Three-Way Stopcock Supplied

Contrast draw, air purge, and balloon isolation are handled without breaking a connection, which supports a clean and efficient workflow.

Ergonomic Handle for High-Pressure Work

The handle profile is designed to keep the effort manageable as pressure rises, which is where inflation devices are most awkward to operate.

Consolidated Supply Through Medigear.uk

Medigear.uk quotes all three references on one account, so a catheter laboratory can order across pressure ratings and gauge types together.

20 mL Syringe Volume

All three references share a 20 mL working volume.

AI30, No Leakage Under 30 atm

The standard analogue reference, specified for use up to 30 atmospheres.

AI40, No Leakage Under 40 atm

The higher-rated analogue reference, for procedures calling for greater pressure.

INT-IDA-233 Digital Gauge Reference

A digital display replaces the analogue dial, rated for no leakage under 30 atmospheres.

30 cm High-Pressure Extension Tubing

Rated tubing connects the device to the balloon catheter and maintains pressure during inflation.

Male Rotating Luer Connector

The tubing terminates in a rotating luer so connections tighten without the tube turning.

Three-Way Stopcock Rated to 500 psi

The supplied stopcock switches between balloon line, contrast source, and closed position.

Manual Pressure Control With Locking Handle

Turning the handle raises pressure, and releasing the lock allows controlled deflation.

Ergonomic Handle Profile

The grip is shaped to reduce the force required as pressure increases.

Single-Use Device Classification

Classified under GMDN term 17541 as a single-use catheter balloon inflator, not intended for reprocessing.

Clear Pressure Display Across Both Gauge Types

Analogue dials use a large printed face, and the digital option presents pressure numerically.

Interventional Cardiology and Radiology Compatibility

The device connects to standard balloon catheter hubs used in coronary and peripheral work.

The INT Medical Inflation Device covers the working requirements of a catheter laboratory across three references, offering a 20 mL volume with either a 30 or 40 atmosphere rating and a choice between analogue and digital pressure display. The 30 cm high-pressure tubing, male rotating luer, and included 3-way stopcock address the practical demands of maintaining pressure and managing contrast during a case. Medigear.uk supplies all three references to UK cardiac catheter laboratories and interventional radiology suites, quoting single boxes or standing volumes. Before supply, Medigear.uk will confirm the sterilisation method, shelf life, box quantity, packing dimensions in LBH mm, the reference code for the digital device, the stopcock pressure rating against the AI40, and UK conformity status.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

It inflates and deflates a dilatation balloon during a procedure. It also holds the balloon at a set pressure while that pressure is read. Typical use is percutaneous coronary or peripheral angioplasty, and balloon-expandable stent deployment. The gauge lets the operator confirm the pressure actually reached. Medigear.uk supplies the device to UK cardiac catheter laboratories and interventional radiology suites.

Both hold 20 mL, and both carry analogue gauges. The difference is the pressure rating. AI30 is specified for no leakage under 30 atmospheres, and AI40 for no leakage under 40 atmospheres. The choice follows the rated burst pressure of the balloons a service uses. Medigear.uk can quote both references together so a laboratory can standardise appropriately.

INT-IDA-233 replaces the analogue dial with a digital display, and is rated to 30 atmospheres. A numeric readout is simply read off. There is no judging where a needle sits between printed marks. That matters when a balloon is held near its rated pressure. INT's own product literature also describes a timing function on its digital devices. Medigear.uk will confirm which functions the supplied revision carries.

The extension tubing is 30 cm and rated for high pressure. It ends in a male rotating luer. The hub connection can be tightened without turning the tube itself. That helps the connection hold pressure through an inflation. INT lists a 60 cm tubing option elsewhere in its range, which Medigear.uk can enquire about if a longer reach is needed.

This needs checking before the AI40 is standardised. The stopcock is stated at up to 500 psi, which converts to roughly 34 atmospheres. The AI40 device itself is rated to 40 atmospheres, around 588 psi. The stated stopcock rating therefore sits below the device rating. Medigear.uk will obtain written clarification from INT Medical on this point.

It is classified under GMDN term 17541 as a single-use catheter balloon inflator, so it is not intended for reprocessing. The sterilisation method and shelf life are not stated in the material supplied. Devices of this class are commonly sterilised with ethylene oxide. Medigear.uk will confirm the actual method, expiry dating, and packaging format rather than assume.

INT Medical Instruments is the brand. The manufacturing entity recorded against the AI30 in the United States device database is Shanghai Kindly Medical Instruments Co., Ltd. The AI30 holds an FDA premarket clearance under number K170027. Medigear.uk can supply the manufacturer details and available regulatory documentation for a procurement or clinical governance file.

The material supplied carries no CE or UKCA marking information. FDA clearance exists for the AI30 in the United States, but that does not establish conformity for the UK market. CE certificate status under Regulation (EU) 2017/745, UKCA status, and the UK Responsible Person all need confirming. Medigear.uk will establish each of these before any unit is supplied.
