Magnetizable stent-grafts enable endothelial cell capture

Magnetizable stent-grafts enable endothelial cell capture.

Emerging nanotechnologies have enabled the use of magnetic forces to guide the movement of magnetically-labeled cells, drugs, and other therapeutic agents. Endothelial cells labeled with superparamagnetic iron oxide nanoparticles (SPION) have previously been captured on the surface of magnetizable 2205 duplex stainless steel stents in a porcine coronary implantation model. Recently, we have coa...

predictors of endothelial cell density of corneal grafts after dsaek

purpose: to evaluate endothelial cell density (ecd) and morphology of clear corneal grafts after descemet stripping automated endothelial keratoplasty (dsaek) and to determine the factors that influence graft ecd postoperatively. methods: seventy-seven eyes (38 right eyes) of 64 patients (34 female subjects) who underwent dsaek for fuchs’ endothelial dystrophy (n=38) or pseudophakic bullous ker...

Endothelial cell seeding of polymeric vascular grafts.

Pioneers in the field of small diameter graft development sought to promote graft endothelialization and, thereby, increase patency by transplanting a varying degree of autologous endothelial cells onto vascular grafts prior to implantation. This process has become known as endothelial cell seeding. The underlying hypothesis is quite simple; that is, by promoting the establishment of the patien...

Computational mechanics of Nitinol stent grafts.

A finite element analysis of tubular, diamond-shaped stent grafts under representative cyclic loading conditions for abdominal aortic aneurysm (AAA) repair is presented. Commercial software was employed to study the mechanical behavior and fatigue performance of different materials found in commercially available stent-graft systems. Specifically, the effects of crimping, deployment, and cyclic...
