摘要： An atherectomy catheter is provided for excising and imaging material in a body lumen. In one embodiment, the catheter comprises a catheter body, a cutting blade, and an imaging device. The cutting blade is mounted on the catheter body and configured to move between a first position and a second position relative to an aperture or cutting window. When the cutting blade is in the second position, the blade substantially closes the aperture on the catheter body. The imaging device which is mounted on or otherwise coupled to the cutting blade is configured to be in an imaging position when the cutting blade substantially closes the aperture or cutter window. This allows the imaging device to survey material within the cutting zone of the atherectomy catheter. By allowing the imaging device to view materials within this cutting zone, material may be imaged and then removed from the body lumen without having to reposition the catheter between each step.

摘要： A tubular prosthesis has a plurality of tubular rings that are radially expandable from a contracted configuration to an expanded configuration. Each ring comprises a plurality of axially oriented struts that are interconnected so as to form a circumferential series of at least one high peak and at least one low peak. The high and low peaks have apices that are oriented in the same axial direction. The apices of the high and low peaks are also oriented in the same direction and the apices of the high peaks are axially offset from the apices of the low peaks. A bridge member couples a pair of adjacent tubular rings together. The bridge member has a first end connected to a first low peak in a first tubular ring and a second end connected to either a high or low peak in an adjacent tubular ring.

摘要： Prosthesis delivery devices and methods are provided that enable precise control of prosthesis position during deployment. The prosthesis delivery devices may carry multiple prostheses and include deployment mechanisms for delivery of a selectable number of prostheses. Control mechanisms are provided in the prosthesis delivery devices that control either or both of the axial and rotational positions of the prostheses during deployment. This enables the deployment of multiple prostheses at a target site with precision and predictability, eliminating excessive spacing or overlap between prostheses. In particular embodiments, the prostheses of the invention are deployed in stenotic lesions in coronary or peripheral arteries, or in other vascular locations.

摘要： Prosthesis delivery devices and methods are provided that enable precise control of prosthesis position during deployment. The catheter for delivering a prosthesis to a treatment site in a body lumen typically carries one or more self-expanding tubular prostheses within a sheath. A radially expandable control member is positionable within the prostheses and has an expanded shape which engages an inner surface of the prostheses to urge the prostheses outwardly against the sheath. The radially expandable control member therefore controls axial position of the prostheses during deployment. Thus one or more prostheses may be deployed at a treatment site precisely. When multiple prostheses are deployed, excessive spacing or overlap between adjacent prostheses is minimized. The prostheses of the present invention are often deployed in stenotic lesions in peripheral arteries as well as coronary arteries and other body lumens.

摘要： Apparatus and methods for delivering prosthetic segments to a body lumen, utilize a device having an elongated flexible member including proximal and distal ends, a plurality of prosthetic segments releasably arranged axially along the elongated flexible member near the distal end and an outer sheath slidably disposed over at least a portion of the prosthetic segments. The apparatus further includes a separator disposed on the outer sheath and adapted to engage the prosthetic segments. The separator is also adapted to be retracted proximally over the prosthetic segments and advanced distally to separate a proximal group of the prosthetic segments from a distal group of the prosthetic segments which are to be deployed in the body lumen.
