    摘要: The invention provides for intra-luminal stents, especially stent having controlled fracture connection, as well as, methods of making and using the same. In one embodiment, a stent for implantation into a vessel has a plurality of annular segments collectively forming tubular shape, characterized by at least first and second adjacent annular segments each defined by a plurality of struts and at least one joint interconnecting respective struts of the first and second segments on a non-permanent basis.

    摘要: A medical device is disclosed for tissue, body lumen and/or cavity closure inside a body of a patient. In one particular application, the medical device can be used for minimally invasive access and closure of a left atrial appendage of the heart. The medical device generally includes a tool used for grasping the appendage, a closure member, and at least one tool to deploy, control, and position the closure member for closing the appendage. The device can also include an expander tool for expanding the working area around the left atrial appendage to improve visibility during the procedure. In other embodiments, the medical device may include other tools, for example an imaging tool for viewing the target area and/or other tools that are considered useful in a left atrial appendage closure procedure.

    摘要: An access tube has a central passage and at least one lumen extending axially between the central passage and an outside wall of the access tube. The lumen carries therein a piercing member for accessing an anatomic space, such as a pericardial space between the parietal pericardia and the visceral pericardia. While the access tube is positioned against the parietal pericardium, a distal end of the piercing member engages and penetrates the parietal pericardium. The distal end of the piercing member entering the anatomic space can then allow the piercing member to advance and form into a supporting structure to create a working space. After the working space is created, an access device can be introduced through the access tube into the pericardial space to perform a variety of procedures inside a patient.

    摘要: A stent includes a substantially cylindrical segment which is deployed in the renal vessel and a flared segment which is deployed in ostial and aortic regions of the vessel. The substantially cylindrical segment provides superior radial strength for maintaining dilated diameter of the renal vessel. The flared segment, which is formed by plurality of slits extending through the sidewall of the stent, expands to conform to the ostial and aortic regions of the vessel. The flared segment can be balloon dilated to enhance conformance of the flared stented segment to the ostial and aortic regions. A stent delivery system capable of delivering and deploying the substantially cylindrical segment and the flared segment is also disclosed.
