Placement of a stent in the pelvic / lower limb region using the arm as entry point

More and more patients that require a vascular stent in the pelvic/lower limb region cannot be treated via the femoral artery approach due to complications associated with previous interventions.

The reasons for this can be scarred tissue at the point of entry along the femoral artery, or there are difficulties in by-passing stenotic segments of the vessel with a guide-wire using the standard femoral approach. Scarring can be caused by patients that have previously received radiation therapy, or due to prior vascular interventions at the femoral artery puncture site.

The so-called transbrachial/transradial approach has been adopted by cardiologists for a number of years already. The limiting factor using the transbrachial/transradial approach in the pelvic / lower limb region in comparison to cardiology was the remote access site. Until now miniaturised catheter materials were often inadequate in their performance to transmit one-to-one rotational control.

Optimed has succeeded in developing a stent delivery system (180 cm long) specially for the arm approach. This new technology masters the complications and restrictions that are usually encountered under even the most challenging circumstances. The sinus-SuperFlex-518 is a flexible, self-expanding nitinol stent specially conceived for the pelvic/lower limb region. The product portfolio is supplemented with the ideally-suited guide-wire (Plywire), introducer sheath (Epsylar) and PTA balloon catheter (Dilexx).

The transbrachial approach represents a safe technique with low complications rates for in and out-patient treatment.
