INT Medical Micro Guidewire Floppy

Cerebral vessels punish equipment. They are narrow, they branch repeatedly, and they curve back on themselves in ways that few other territories do. A wire pushed along that route is bent and rebent constantly, and a conventional core gradually takes a set, acquiring kinks that stop devices from tracking cleanly.

Nitinol answers that. It is superelastic, meaning it recovers its shape after deformation that would permanently bend another alloy. A wire built from it can follow a tortuous route repeatedly and emerge unchanged, which matters over a long procedure where the same wire is advanced, withdrawn and advanced again. INT presents this as the wire maintaining its shape throughout, and that is the correct framing.

The extension arrangement addresses a separate and very practical problem. Neurointerventional work involves exchanging microcatheters over a wire that has already found a difficult route, and losing that position means starting again. Removing a catheter without losing the wire requires a wire more than twice the catheter length, which conventionally means either stocking long wires throughout or exchanging to one mid-procedure. An extension coupled to the back of the wire avoids both. The wire stays exactly where it is, gains the needed length, and the catheter comes off it. Tapering serves the first problem again, since a wire narrow enough to reach distal vessels would lack support along its whole length if it were that thin throughout.

Tip stiffness is chosen based on the vessel and the target, and floppy wires suit navigation rather than crossing resistant lesions. Medigear.uk supplies the instructions for use with every order.

Nitinol Resists Deformation

A superelastic core recovers from bends that would permanently kink another alloy, so a wire taken through tortuous anatomy repeatedly still tracks cleanly afterwards.

Extension Converts Working to Exchange Length

Coupling 115 cm to a 205 cm wire gives 320 cm without exchanging wires, so a hard-won position across the target is never given up to gain length.

One Item Covers Both Length Requirements

Stocking the E references means a single reference serves both delivery and exchange, rather than holding short and long wires separately.

Both Diameters Published

Distal and proximal outer diameters are given for every series, showing the taper directly, which INT's soft tip range does not do.

Tapered Construction

A 0.007 inch distal section reaches vessels a uniform wire could not, while the wider proximal shaft retains the support a thin wire would lack.

Extension Matched to Proximal Diameter

The extension is sized to the shaft it joins, so the coupling carries no step that could catch inside a catheter during withdrawal.

Complements Rather Than Duplicates the Soft Tip Range

One wire is shaped by the operator, the other resists being shaped by the anatomy, so the two answer different problems within the same field.

The INT Medical Micro Guidewire Floppy is the shape-stable counterpart to INT's soft tip wire, and the two make sense as a pair. Where one is flattened so an operator can shape and reshape it, this one is nitinol, so the anatomy cannot reshape it, and neurointerventional work needs both. The extension arrangement is the standout feature, since converting a 205 cm wire to 320 cm without exchanging it preserves a position that may have taken considerable effort to reach. Publishing both distal and proximal diameters is also an improvement on the soft tip sheet. Two things need to be obtained. Floppy 014 and Floppy 014 EX carry identical published dimensions with nothing to distinguish them, and no tip load appears for either wire. Medigear.uk will resolve both, with radiopaque and coating lengths, sterility status and UK conformity, before offering this range.
