Active clinical trials for "Peripheral Vascular Diseases"

The ASI Non-Invasive Arterial Stiffness Screening Device (ASI Device) is an investigational device under development for the non-invasive assessment of arterial stiffness. The ASI Device is considerably smaller and more cost effective than its commercially available counterparts. As the device is readily portable, it is intended to be targeted for use in the community (or at home), as opposed to within the hospital or clinic setting only. However, as the device is still under development, it is not known whether it is capable of determining arterial stiffness with the same sensitivity and consistency as those already in commercial use. An added variable is the fact the sensor for the ASI Device is located on the fingertip. Validation is a prerequisite for obtaining Health Canada approval of devices for diagnostic purposes. The ASI Device has not been tested against other instruments capable of providing similar measurements. Therefore, a clinical trial to compare the ASI Device against similar devices is necessary. The study will compare measurements of arterial stiffness and other central haemodynamic parameters obtained with the ASI Device against similar measurements from devices that have already been approved for this purpose by Health Canada/United States Food and Drug Administration (FDA).

The BARD® Venovo™ Venous Stent Study is a non-randomized clinical study intended to collect confirmatory evidence of the safety and effectiveness of the Venous Stent for the treatment of iliofemoral occlusive disease.

The purpose of this study is to evaluate the safety and efficacy of an excimer laser in the treatment of patients with lower extremity vascular disease with chronic total occlusions.

This is a single center, open label, prospective, randomized, controlled study in patients with non- revascularizable moderate or severe lower extremity Peripheral Arterial Disease (PAD) receiving autologous stem cells therapy (minimally manipulated). This study will enroll a maximum of 10 subjects in this study. The patients will be divided into two groups. One group will receive Adipose Derived Stem Cells (ADSCs) alone and the other group will receive low frequency ultrasound before the addition of ADSCs. The randomization will be 1:1. If the results of this pilot study are not clearly different, there will be a need for a phase II study to support the results. Baseline, 6 week, 3 month and 6 month assessments of 6 min walking distance (6MWT), Ankle Brachial Indexes (ABIs)/Toe Brachial Indexes (TBIs), Transcutaneous Partial Oxygenation (TcPO2) and Rutherford assessments will be performed for the study group. Prior to the stem cell treatment, the ultrasound group patient will receive noninvasive transcutaneous pulsed focused ultrasound around the involved vessel(s) in the affected extremity. All patients will then receive 200 million autologous stromal vascular fraction cells containing adipose derived stem cell therapy: 1/3 of the cells will be delivered intra-venous proximal to the lesion (not retrograde), 1/3 of the cells will be delivered intra- adventitia proximal to the lesion and 1/3 of the cells will be delivered by intra- muscular injection along the vessel path (20-30 injections each separated by1.5 inch). Standard therapy for PAD patients will not be interrupted for the duration of the study. Standard therapy for PAD is defined as cardiovascular general measures like lifestyle changes, smoke cessation, exercise, cardiovascular rehabilitation, etc. All participants have already received maximal non-surgical therapy. Safety will be monitored on an ongoing basis.

A multi-center, post-CE Mark study designed to evaluate the performance of the Intact Vascular Tack-IT Endovascular Stapler™ in subjects with vascular flaps (e.g.; post-angioplasty dissection) resulting from percutaneous transluminal balloon angioplasty (PTA) of superficial femoral or popliteal artery(ies).

Evaluate the possibility of optimization of therapy with prostanoids (iloprost), in patients with Fontaine's stage IIb severe chronic ischemia, both in patients eligible for surgery both in patients for which it is only possible medical therapy

This study is designed to evaluate the safety and efficacy of a Paclitaxel-coated percutaneous transluminal angioplasty (PTA) Catheter in the treatment of patients with peripheral arterial disease.

The objective of this study is to examine the feasibility of using a collaborative-care, home-based rehabilitation program to improve functional outcomes for people recovering from lower limb amputation caused by vascular problems and/or diabetes complications. The primary hypothesis is that the rehabilitation program will result in greater improvements in performance-based and participant-reported measures of physical function, compared to standard of care after outpatient rehabilitation.

To assess the safety of performing a percutaneous fem-pop bypass using the PQ Bypass Guidewire Delivery System and commercially available stent grafts.

The objective of this study is to compare the effectiveness of standard moist dressings and PICO single-use negative pressure dressings in post-operative lower extremity bypass patients. This study will compare the dressings' ability to decrease swelling, decrease post-operative infection, and improve mobility and quality of life measures. Subjects will be asked to participate in this study because they will undergo a lower extremity bypass using the ipsilateral great saphenous vein. Subjects will then be randomized to two post-operative treatment groups. One group will receive standard sterile gauze and the other will receive PICO single-use negative pressure dressings. Both groups will be assessed for study measures in follow-up visits as clinically indicated up to 1 year with the 30 day timepoint as the primary outcome for study measures.
