PURPOSE Arteriovenous fistulae (AVFs) created by conventional surgical techniques are associated with suboptimal short- and long-term patency. This study investigated the feasibility of creating fistulae with a percutaneous system and evaluated the utility of percutaneous AVFs (pAVFs) in providing hemodialysis access. MATERIALS AND METHODS From August(More)
AIMS This paper reports the technical feasibility of using the Direct Flow Medical percutaneous aortic valve (PAV) to treat patients with severe aortic stenosis (AS). METHODS AND RESULTS Eight patients with critical AS underwent temporary implantation of the PAV. Two patients received open surgical implantation of the device while six patients underwent(More)
The purpose of this study was to determine the safety and efficacy of a new endoluminal occlusion device, ArtVentive endoluminal occlusion system (EOS), to occlude the spermatic vein in symptomatic males with varicoceles. The ArtVentive EOS device has been developed for percutaneous, peripheral occlusion of the peripheral arterial and venous vasculature.(More)
The Vascular Closure System (EVS ) is the first device to utilize a staple mechanism to close percutaneous femoral arteriotomies following catheter-based procedures. To assess safety and efficacy, the EVS was used to close 89 consecutive femoral arteriotomies. Closure success was defined as complete cessation of bleeding within five minutes of staple(More)
OBJECTIVES This study evaluated the first clinical use of a new endovascular approach to renal denervation, using chemical neurolysis, via periadventitial infusion of dehydrated alcohol (ethanol) to perform "perivascular" renal artery sympathetic denervation. BACKGROUND Renal denervation remains a promising technology for the treatment of hypertension and(More)
BACKGROUND Current surgical and medical treatment options for functional mitral regurgitation (FMR) are limited and additional interventional approaches are required. OBJECTIVES This study sought to report the safety and performance data from the feasibility study with a novel direct annuloplasty system. METHODS Seventy-one patients with moderate to(More)
Although arteriovenous fistulae are the preferred form of dialysis vascular access they continue to have significant problems with maturation failure. The Optiflow device is a sutureless anastomotic conduit which could potentially reduce surgical time and also standardize the surgical procedure. We report herein on the "First in Man" experience with the(More)
AIMS Transcatheter aortic valve implantation (TAVI) has become a viable option for selected high-risk patients with severe and symptomatic aortic stenosis. First- and second-generation TAVI devices are either self- or balloon-expandable, and are often not repositionable or not fully retrievable, leading to suboptimal positioning in some cases. This may(More)
