摘要： A catheter system (10) for positioning of a medical instrument (50) that includes a first elongate member (12) having a first lumen. The catheter system also includes a second elongate member (14) that includes a second lumen that receives the medical instrument. The second elongate member is coupled directly to the first elongate member, and the second elongate member is operable to be at least partially segmented generally along a second longitudinal axis thereof to allow movement of the medical instrument outside the second lumen. The second elongate member is selectively collapsible and expandable to change size of the second lumen.

摘要： An improved medical device for intraluminal endovascular stenting comprises a stent (30) having a hollow cylindrical body fabricated from a plurality of circumferentially extending rings (26a, 26b) having an undulating series of peak (24) and valleys (25). Links (21, 22) join the adjacent rings and are shaped to promote flexibility of the stent during its delivery to a treatment site and adequate scaffolding of a vessel following its deployment at the treatment site. Improved access to side-branches off the vessel is achieved by providing enlarged cell size for the stent when expanded, whilst maintaining adequate scaffolding. This is achieved by interrupting the straight sections between adjacent peaks and valleys by an inflection point at which one arm (21a, 21b) of one link is connected to join adjacent rings together.

摘要： A valve retainer is connected to an elongate delivery member. The valve retainer is configured to releasably secure a prosthesis (e.g., a heart valve prosthesis) to the delivery member during delivery to a target site in a body (e.g., a native valve annulus). The valve retainer includes a rotational identifier that identifies the rotational orientation of the valve retainer when the valve retainer is positioned proximate to the target site. A heart valve prosthesis can include a commissural post that has a predetermined rotational position relative to the rotational identifier, such that the heart valve prosthesis can be rotationally aligned with the native commissures of the native valve by rotating the delivery member and the valve retainer until the commissural post is aligned with a native valve commissure and the rotational identifier is visible.

摘要： A bifurcated catheter (100) includes a first catheter branch (102) having a first distal portion and a second catheter branch (104) having a second distal portion. The first and second distal portions are linked together for delivery to the bifurcated region. Upon delivery to the bifurcated region, the first and second distal portions are released from each other such that the first and second catheter branches (102, 104) may be tracked into first and second vessel branches, respectively. The first and second distal portions can be linked together by an appendage (130) disposed on the first distal portion that is sized and shaped such that the appendage fits snugly within a distal opening of the second distal portion, a cup (230) disposed on the first distal portion that is sized and shaped to snugly receive the second distal portion, moving pocket (360) disposed on the first distal portion and slidable relative to the first distal portion that is sized and shaped to snugly receive the second distal portion, or a sheath (480) coupled to the first distal portion and wrapped around the second distal portion.

摘要： Heart valve delivery systems and methods of delivering and implanting heart valves using delivery catheters are disclosed. The delivery systems can include a handle assembly with a rotatable control knob and a catheter including an introducer shaft, an intermediate shaft extending from the handle assembly, an inner shaft extending from the handle assembly, and a capsule for containing a prosthesis. The distal end of the capsule can be connected to a distal end of the inner shaft, which can be moved in a distal direction by the rotatable control knob to deploy the prosthesis. By advancing the introducer through the deployed prosthesis and retracting the capsule to mate with the introducer, a smooth profile can be created for retraction of the system through the deployed prosthesis, minimizing hang-ups and snagging.
