摘要： An occlusion device includes a center assembly having a flexible section formed by a spring connector and a safety tether. The flexible spring connector gives the center assembly improved torque and flexure characteristics, which allows the occlusion device to better conform to the contours of the heart. The safety tether serves to further ensure the structural integrity of the center assembly.

摘要： An occlusion device for the closure of atrial or ventricular septal defects, for the closure of patent ductus arteriosus, patent foramen ovale, or other vascular defects. The occlusion device comprises a center section extending in an axial direction, with upper and lower stranded wire fixation devices emanating from the center section. The stranded wire fixation devices have been heat treated and formed with a shape memory. The stranded wire fixation devices are formed of multiple wire strands and have atraumatic tips. Attached to the fixation devices are heparin treated sheets, which serve to occlude the opening and significantly reduce the occurrence of thrombosis at the device.

摘要： A method of delivering a prosthetic mitral valve includes delivering a distal anchor from a delivery sheath such that the distal anchor self-expands inside a first heart chamber on a first side of the mitral valve annulus, pulling proximally on the distal anchor such that the distal anchor self-aligns within the mitral valve annulus and the distal anchor rests against tissue of the ventricular heart chamber, and delivering a proximal anchor from the delivery sheath to a second heart chamber on a second side of the mitral valve annulus such that the proximal anchor self-expands and moves towards the distal anchor to rest against tissue of the second heart chamber. The self-expansion of the proximal anchor captures tissue of the mitral valve annulus therebetween.

摘要： An occlusion device having laminated polyvinyl alcohol sheets for occluding a defect. The laminated polyvinyl alcohol sheets provide an increased tear strength to the sheets that allows the device to be fully retrievable through the same catheter used to deploy it. The laminated sheets are created by obtaining thin sheets of polyvinyl alcohol foam, arranging the sheets on one another, and applying heat and pressure to laminate the sheets together.

摘要： A method of forming a PVA foam structure for use in an occlusion device such that the PVA foam structure comprises non-thrombogenic properties. The method comprises forming a PVA gel and incorporating heparin into the PVA gel. The PVA foam structure is then treated with the PVA gel and heparin mixture, such as by soaking the PVA foam structure in the gel.
