摘要： A medical device such as a catheter may have an elongate shaft that includes a hypotube having a helical cutting formed therein. The elongate shaft may define a lumen that extends within the elongate shaft. An electroactive polymer may be disposed over at least a portion of the hypotube. A medical device may include a spiral cut hypotube having a constant pitch and may be configured to reversibly and temporarily alter the pitch of at least a portion of the spiral cut hypotube. In some cases, the medical device may be configured to reversibly and/or temporarily alter a compressive strength of at least a portion of the spiral cut hypotube.

摘要： A method includes: providing a substrate, depositing a ceramic and an extractable material onto the substrate, forming a porous structure in the ceramic by removing the extractable material, and utilizing the ceramic in an endoprosthesis. An endoprosthesis, such as a stent, including a coating formed of a ceramic and an extractable material that can be removed from the coating to form voids is also disclosed.

摘要： Devices and methods for centering an intravascular filter within a blood vessel are disclosed. A filter system in accordance with an exemplary embodiment of the present invention may include an intravascular filter, a filter sheath adapted to contain the intravascular filter, and a centering member adapted to assume a preset shape when deployed within a blood vessel. The centering member may comprise an elongated wire having a hoop section adapted to radially expand against the inner wall of the blood vessel when deployed. In some embodiments, multiple centering members can be employed to facilitate centering of both the intravascular filter and the filter sheath within the blood vessel, if desired.

摘要： A catheter assembly configured for treatment of a vessel bifurcation. The catheter assembly includes a catheter shaft and first and second balloons. The second balloon extends radially outward relative to the first balloon when expanded. A valve arrangement controls expansion of the second balloon. Portions of the valve arrangement can be positioned at proximal and distal end portions of the catheter shaft. Typically, the first balloon is expanded followed by expansion of the second balloon. A stent having a lateral branch opening is operatively mounted to the first balloon. The second balloon is configured to extend through the lateral branch opening when the second balloon is expanded.

摘要： A filter device positionable within a blood vessel for trapping emboli in the vessel, the filter device having a head and a plurality of divergent legs each secured at a first end to the head; each leg having one or more hooks at a second end. The hooks can include an expandable and contractible sleeve or hook that provides securing means for the legs and which also allows for easy removal of the filter device.
