摘要： A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the frame attached thereto. The frame may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes an integrated handle shaft and balloon catheter. A valve holder is stored with the heart valve and the handle shaft easily attaches thereto to improve valve preparation steps.

摘要： An infusion catheter includes a catheter body having a proximal end, a distal end, and two or more lumens extending therethrough. The infusion catheter also includes an infusion tube having a proximal end, a distal end, and one or more ports disposed therethrough. The first lumen of the catheter body is in fluid communication with the lumen of the infusion tube. A central member has a distal end connected to the distal end of the infusion tube, a proximal end, and a proximal portion slidably received in the second lumen of the catheter body. The infusion tube is disposed relative to the central member such that axial advancement of the central member relative to the catheter body radially collapses the infusion tube over the central member and axial retraction of the central member relative to the catheter body radially expands the infusion tube about the central member.

摘要： Devices and methods for removing a foreign object from a body lumen are disclosed. An embolectomy device can include a filter basket having a plurality of filter struts forming a cage-like structure that can be expanded to circumferentially surround the incoming foreign object. A support frame including a proximal hoop and one or more rail members may be employed to support the filter basket. The support frame and filter basket can be coupled to a pusher wire that can be used to manipulate the device within the body. In certain embodiments, the filter struts may vary in thickness to impart a desired flexibility characteristic to the device. Methods of manufacturing such devices are also disclosed.

摘要： A catheter comprises a catheter shaft, at least a portion of which defines a medical device receiving region, and at least one sleeve. The at least one sleeve comprises a tubular member constructed and arranged to transition between an extended state and a retracted state. The tubular member has a first portion being engaged to a portion of the catheter shaft adjacent to the medical device receiving region. In the extended state a second portion is constructed and arranged to at least partially overlay the medical device receiving region. In the retraced state the second portion is removed from about the medical device receiving region. At least one of the first portion and the second portion of the tubular member are at least partially constructed from a shape memory material.

摘要： A stent delivery system is disclosed which includes an inner tube disposed within an outer tube in an annular space disposed therebetween. The distal end of the inner tube extends beyond the distal end of the outer tube and a balloon extends between the distal end of the outer tube and the distal end of the inner tube. A stent is disposed over the balloon. A heating mechanism is provided to heat the balloon which, in turn, transmits heat to the stent for expansion. An inflation media for the balloon is transported through the annular space to ensure continuous contact between the balloon and stent during deployment of the stent.
