Beschrijving
Inclusion Criteria:
- Participants with peripheral artery occlusion who require elective lower-limb 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
Exclusion Criteria:
- 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
- Reduced liver function, defined as: >2x the upper limit of normal for serum bilirubin, International Normalized Ratio (INR) >1.5 or prothrombin time (PT) >18 seconds
- Any active local or systemic infection
- Known heparin- induced thrombocytopenia, active bleeding disorder and/or any coagulopathy or thromboembolic disease
- Allergies to study device (nitinol) or agents/medication, such as contrast agents, aspirin or NOACs, that can't be controlled medically
- 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)

Experimenteel: XPAD
|
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.
