摘要： Devices and techniques for modifying and maintaining a configuration of an occlusion device for the closure of physical anomalies, such as an atrial septal defect, a patent foramen ovale (PFO), and other septal and vascular defects are described. The devices and techniques relate particularly to, but are not limited to, modifying and maintaining a configuration of a PFO occluder made from a polymer tube. The proximal end of a catch member may be provided with one or more protrusions, or arms, or bump or other element for securing the occluder in a partial or fully deployed configuration, either temporarily or permanently.

摘要： The invention provides an intracardiac occluder (10), which has biological tissue scaffolds as occlusion shells, for the percutaneous transluminal treatment of an intracardiac defect. The intracardiac occluder includes a proximal support structure (24) supporting the proximal occlusion shell (18) and a distal support structure (34) supporting the distal occlusion shell (20). In one embodiment, biological tissue derived from the tunica submucosa layer of the porcine small intestine forms the occlusion shells.

摘要： The clips (18) of the present invention include two closure members (22, 24) joined by at least two spaced central connecting members (36, 38). The clips (18) are designed such that the at least two central connecting members (36, 38) extend through the inclined PFO tunnel and the two closure members (22, 24) compress the overlapping layers of septal tissue, i.e. septum primum and septum secundum, together to close the PFO tunnel. The clips (18) of the present invention take various forms depending, in part upon the distribution of force required to close a given PFO. Thus, embodiments of the closure members (22, 24) include arcuate peaks (26), loops (46, 48), and prongs (96, 98). In yet other embodiments, the closure members (22, 24) include centering elements (49) for centering the device in the desired delivery location and a tissue scaffold (108).

摘要： A gripping device (10) is operative within a body vessel which includes an elongate, flexible support body (12) having a plurality of spaced gripping members (22) attached to the support body to extend axially outwardly from the outer end thereof. The gripping members are formed to have an expansion position where they angle laterally from the support body. A cone shaped flexible liner (34) forming an open ended enclosure in the expansion position of the gripping members has an outer end connected to the distal ends (26) of the gripping members, and an inner end connected to the support body. The flexible liner is surrounded by the gripping members.

摘要： An expandable catheter (10) accommodates a medical device that is being removed from a body with a larger diameter than the catheter. The same catheter may be used to reposition a device within the body to an alternative delivery site. A catheter or sheath may be used to deliver a medical device, surgical instrument, or biological sample.

摘要： Apparatus, systems, and methods for forming a hole in biological material, such as tissue walls, adjacent vessels or adjacent regions of an organ such that access to opposing surfaces of the biological material can be achieved. In general overview the system may include ,an elongate member for positioning and deploying a flexible member in the heart. In one embodiment apparatus and methods are provided for aligning and fixing the position of the tip of a cutting member for cutting a hole in the septal wall of a heart. In another embodiment, subsequent to cutting a tissue wall an apparatus for obstructing holes in the septal wall is inserted to limit the flow of blood through a plurality of holes in a tissue wall.
