摘要： A delivery device for implanting a medical device that includes an expandable fixation member adapted to fix the position of the medical device within a lumen of a human body. The delivery device has an inner shaft rotatably disposed in a tubular outer shaft. A retention member is secured to and rotatable with the inner shaft and has a free end and a retainer portion adapted to protrude outwardly through an exit aperture in the outer shaft to extend circumferentially about the exterior of the outer shaft. The fixation member of the medical device may be retained on the tubular shaft in a low profile configuration by the outwardly protruding retainer portion and may be released to expand upon retraction of the retainer portion in response to rotation of the inner shaft.

摘要： A method for forming a wave form for a stent. The wave form includes a plurality of substantially straight portions and a plurality of curved portions. Each curved portion connects adjacent substantially straight portions. The method includes feeding a formable material between a first die and a second die, the first die having a protruding surface in the shape of the wave form, and the second die having a recessed surface in the shape of the wave form complementing the protruding surface of the first die, pressing the formable material with the protruding surface of the first die into contact with the recessed surface of the second die, and shearing the wave form from the formable material with shearing forces created by the pressing.

摘要： Waveforms for forming helical stents with opposing and/or alternating pitch angles along their lengths are disclosed. A wire is bent to form a waveform having a series of sinusoidal segments between a first end and a second end thereof. Each sinusoidal segment is longitudinally offset from its adjacent segment(s). Each waveform includes at least one sinusoidal segment having a first portion in which the amplitude between consecutive turns of the wire gradually increases and a longitudinally offset second portion in which the amplitude between consecutive turns of the wire gradually decreases. The waveform is wrapped from one end to the other about a mandrel to form the stent and depending on the arrangement of sinusoidal segments along the waveform may have opposing and/or alternating pitch angles along a section or an entire length of the stent.

摘要： The present invention is a device for delivering a self-expanding stent. The device has an inner and an outer shaft moveable with respect to the inner shaft. The self expanding stent is received on the inner shaft adjacent its distal end. A tapered tip is located on the inner shaft distal end and it forms a smooth transition from the deliver y device to the guide wire extending therethrough. A handle allows the practitioner to deploy the stent single handedly. The stent may have its segments in a first radial configuration for deliver of the stent or the stent may have a plurality of segments in a first radial configuration and a plurality of second segments in a second radial position.
