摘要： This invention is directed to an expandable stent for implantation in a body lumen, such as an artery, and a method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common axis and interconnected by one or more links. A Y-shaped member is comprised of a U-shaped member and a link having a curved portion and a straight portion to improve the flexibility and thereby improve the fatigue performance of the Y-link junction.

摘要： The present disclosure is directed to a multi-segment device, such as an intravascular guide wire. The multi-segment device includes an elongate first portion comprising a first metallic material, an elongate second portion comprising a different metallic material, the first and second elongate portions being directly joined together end to end by a solid-state weld, and a heat affected zone surrounding an interface of the weld where the first and second portions are joined together, wherein the heat affected zone has an average thickness of less than about 0.20 mm.

摘要： Catheter having an elongate tubular shaft including an inflation lumen and a guidewire lumen defined therein, the guidewire lumen extending along at least a distal length of an inner tubular member of the elongate tubular shaft. The catheter includes a distal tip member having a proximal end and a distal end, wherein the distal tip member is monolithic and the proximal end of the distal tip member is secured to a distal end of the inner tubular member. The catheter includes a balloon having a proximal portion and a distal portion, the proximal portion of the balloon sealingly coupled to the distal portion of the elongate tubular shaft. The distal portion of the balloon is sealingly coupled to the distal tip member and the balloon defines an inner chamber in communication with the inflation lumen, wherein the proximal end of the distal tip member is disposed within the inner chamber.

摘要： The invention provides improved devices, systems, and methods for tissue approximation and repair at treatment sites. The invention provides devices, systems, and methods that may more successfully approximate and repair tissue by improving the capture of tissue into the devices. The invention may be a one-way mechanism that allows tissue to enter the mechanism but not easily exit, such as a leaf-spring, a protrusion, a pivoting arm and one or more frictional elements.
