    摘要: A stent delivery catheter and method for making the same includes a tubular balloon, an elastic sleeve, and a stent. The balloon is mounted around a catheter shaft, and the stent is crimped onto the balloon. The elastic sleeve is positioned between the balloon and the stent, the sleeve extending beyond the ends of the stent where the ends of the sleeve are fixed to the catheter shaft. Sleeve material is gathered and folded over the ends of the stent to retain the stent snugly against the balloon during delivery.

    摘要: An apparatus for centering a radiation delivery device at a selected location in a body vessel such as a coronary artery. An elongated catheter is insertable into the body vessel until the catheter head is in the desired position. The catheter has a guidewire lumen, inflation lumen and treatment lumen running lengthwise. The catheter head includes an expandable mechanism for engaging the vessel internal wall with the treatment lumen centered in the vessel. At least one channel is provided extending past the expandable mechanism so that a fluid, such as blood, can perfuse past the catheter head. A radiation delivery device, such as a wire having a radiation source at the distal end can be inserted into the treatment lumen to uniformly irradiate the vessel wall at the selected location.

    摘要: A stent delivery balloon catheter system includes a pair of retainers which are anchored to the catheter to hold the stent against the balloon until the stent is to be deployed. Each retainer is made of filaments which are woven together to form a braided tube shaped structure. Further, each retainer has one end which is anchored to the catheter while the free end of the retainer overlaps a respective end of the stent. Upon inflation of the balloon for deployment of the stent, the balloon also urges against each retainer. This causes the woven tube structure of the retainer to expand, and thereby shorten. As the retainers shorten, they also withdrawn from the stent, and thereby release the stent for deployment.

    摘要: An over-the-wire catheter provides substantially shadow-free delivery of radiation to a body lumen by having a treatment region wherein a guidewire tube and a radiation source tube form a parallel double helix configuration. When a radiation source is inserted into the radiation source tube and a guidewire is present in the guidewire tube, no portion of the treatment site will be obscured from all radiation emitted by the radiation source because, within the treatment region, the guidewire and the radiation source are not in a conventional, axially parallel configuration. Optionally, a balloon may be mounted about or adjacent the treatment region of the catheter, the balloon providing centering and/or dilatation functions.

    摘要: A method of deploying a stent graft includes radially constraining proximal apexes of a proximal anchor stent ring of the stent-graft in a space between merlons of a castellated sleeve of a tip and a spindle having spindle pins, the proximal apexes extending around the spindle pins. A graft material of the stent-graft is radially constrained in a primary sheath, a proximal end of the graft material being attached to distal apexes of the proximal anchor stent ring. The proximal anchor stent ring further includes struts extending between the proximal apexes and the distal apexes. The primary sheath is retracted to allow the proximal end of the graft material and the distal apexes of the proximal anchor stent ring to pivot out beyond the confines of the sleeve to a large angle as the proximal end radially expands. The struts then extend through embrasures of the castellated sleeve. The tip is advanced to deploy the proximal apexes.

    摘要: Embodiments hereof relate to a guidewire formed from an elongated shaft, at least a portion of the shaft having an outer layer, a plurality of channels formed through the outer layer, and an inner core. The outer layer is formed from a material non susceptible to erosion by an erosion agent and the inner core is formed from a radiopaque material susceptible to erosion by the erosion agent. When exposed to the erosion agent, core material adjacent to the channels is removed to form a pattern of integral radiopaque segments or markers with a plurality of voids therebetween. By controlling the location of channels and the rate of erosion of the core material, the pattern of integral radiopaque segments and voids allow for in situ measurement when viewed under fluoroscopy.

    摘要: The invention is an intraluminal therapy catheter having a least two treatment members disposed near the distal end of the catheter, the members being independently inflatable to perform angioplasty and/or fluid-sourced brachytherapy. A first treatment member is helically mounted about the shaft of the catheter, and forms a helical perfusion channel when inflated into contact with the vessel being treated. In a first embodiment of the invention, the second treatment member is also helically mounted about the catheter shaft and capable of forming a helical perfusion channel when inflated into contact with the vessel. The first and second treatment members are intertwined to form a double helix configuration wherein each member is capable of being inflated to generally fill the helical perfusion channel created by simultaneous inflation of the other member. In a second embodiment of the invention, the second treatment member is a tubular balloon mounted generally coaxially about the catheter shaft, adjacent to the first treatment member.
