Официальное название
Prospective, Non-randomized, European Feasibility Clinical Study to Assess the Safety and Performance of the Xeltis Peripheral Artery Disease (XPAD) Bypass Conduit.
Обзор
A prospective, single arm, non-randomized European feasibility study to evaluate the safety and performance of the XPAD conduit in patients with peripheral arterial occlusive disease (PAOD), scheduled to undergo elective lower-limb, above or below the knee, bypass surgery.
Вмешательства
- Устройство XPAD conduit
The XPAD bypass conduit is a sterile, restorative biodegradable polymer-based vascular conduit, consisting of a tubular structure with a 33cm length and 6mm inner diameter. It is comprised of a highly porous polymer matrix and an embedded electropolished nitinol reinforcement layer (Strain Relief System). The XPAD conduit is in a straight configuration and may be implanted in the lower limb for elective bypass surgery.

- Participant has Rutherford grade 3 or 4 occlusive vascular disease and TASC C or D lesions.
- At least 18 years of age at screening
- Suitable anatomy while avoiding joints (assessed by a pre-procedural contrasted CT scan or previous angiogram assessed up to 90 days prior to baseline)
- Participant has been informed of the nature of the study, agrees to its provisions, and has provided written informed consent
- Participant has been informed and agrees to pre- and post-procedure follow-up, including follow-up angiography
- Life expectancy of at least 24 months
Критерии исключения
- Participant requires, or is scheduled for, a cardiac surgical procedure or a different vascular surgical procedure within 30 days of study procedure.
- Stroke or myocardial infarction event within 6 weeks of the procedure or evidence of prior massive stroke (Modified Rankin Scale 3 or above)
- History of acute arterial occlusion requiring an emergent intervention within the last 12 months
- Severe chronic renal insufficiency (serum creatinine >2.5 mg/dL) or undergoing hemodialysis
- Previous renal transplant
- Uncontrolled arterial hypertension (BP >200 mmHg) at 2 successive readings
- Uncontrolled or poorly controlled diabetes
- Abnormal blood values that could influence participant recovery and or/ graft hemostasis

- Previous enrolment in this study
- Participant is participating in another study
- Pregnant or breastfeeding woman or woman in fertile period not taking adequate contraceptives
- Any other condition which, in the judgement of the investigator would preclude adequate evaluation for the safety and performance of the study conduit
Intra-operative exclusion criteria:
1\. Unsuitable anatomy to implant the XPAD conduit (e.g. target vessel diameter smaller than anticipated; severe calcification)
