Two doctors, one question.
“When a standard endovascular revascularization approach is not possible for patients with long-segment peripheral artery blockages, can we create a safe, effective, minimally-invasive solution that causes less trauma to the body than open femoral-popliteal bypass surgery?”
This was the challenge the founders of PQ Bypass set out to solve.
Out of this question came the PQ Technology Suite. Used together for a PQ DETOUR procedure, these technologies present a novel, percutaneous approach to femoral-popliteal bypass surgery. Used on their own for a standard lower-limb endovascular intervention, they are designed to be powerful options for treating long-segment lower extremity disease.
TORUS STENT GRAFT SYSTEM
The PQ Stent Graft System features a flexible, self-expanding composite structure made of a nitinol wire frame encapsulated in ePTFE. Designed for flexibility and robust durability to help maintain an open lumen, the PQ Stent Graft System is under investigation in Europe for both standard intra-arterial placement and for use in the PQ DETOUR procedure.
The PQ Snare is an over-the-wire, dual-nitinol-caged endovascular scaffold created to present a destination and snare for guidewires, then extract them through the tibial vein scaffold.
PQ CROSSING DEVICE
The PQ Crossing Device is a spring-loaded guidewire support and delivery system. During the PQ DETOUR procedure, it is designed to create initial artery-vein-artery communication.
PQ DETOUR Procedure
The PQ DETOUR procedure is a novel approach to fully-percutaneous femoral-popliteal bypass procedure. Using fluoroscopic guidance, a series of proprietary PQ Bypass Stent Grafts are deployed from the popliteal artery into the femoral vein, and from the femoral vein into the superficial femoral artery in a continuous, overlapping fashion through two independent fistulas. The intended result is a large lumen, endograft bypass that delivers unobstructed, pulsatile flow from the SFA ostium to the Popliteal artery. The PQ DETOUR procedure is designed to provide long-term durability while minimizing trauma to the body, hospital stays, and rehabilitation times associated with open surgery.
The PQ DETOUR Procedure is currently under investigation in Europe in the DETOUR I Clinical Trial. The objective of the DETOUR I trial is to assess the safety and performance of the PQ Technology Suite for fully-percutaneous femoral-popliteal bypass.
