摘要： An infusion/guide catheter which is adapted to be introduced into a coronary ostium of a coronary artery of the heart of a patient through an opening in an aorta of the patient, permitting blood perfusion from the aorta into the ostium. Preferably, the catheters can be placed without the use of fluoroscopy. In one embodiment, the infusion catheter generally comprises a tube having at least one lumen, a proximal end, and a distal end, the tube having at least one bend to facilitate placement of the distal end of the tube into the ostium of the coronary artery when the proximal end of the tube extends from the opening in the aorta, wherein the distal end of the tube is configured to fit within the coronary ostium while still permitting blood perfusion from the aorta into the ostium. The catheter, can be used to deliver a fluid, more locally in the heart to enhance the efficiency of fluid or drug administration. Several embodiments include a light delivery portion capable of illuminating a distal end of the catheter for visualization thereof through the vasculature. A guidewire having a light delivery portion is also capable of illuminating a distal end of a catheter for placement of the catheter in a coronary vessel without the use of fluoroscopy.
摘要翻译：输液/引导导管，其适于通过患者主动脉中的开口引入患者心脏的冠状动脉的冠状口，允许从主动脉进入口腔的血液灌注。优选地，可以在不使用荧光透视的情况下放置导管。在一个实施例中，输注导管通常包括具有至少一个内腔，近端和远端的管，该管具有至少一个弯曲部，以便于将管的远端放置在冠状动脉的口中当管的近端从主动脉中的开口延伸时，其中管的远端构造成适合于冠状口中，同时仍然允许从主动脉进入口腔的血液灌注。导管可用于在心脏中更局部地输送流体，以提高流体或药物施用的效率。几个实施例包括能够照射导管的远端的光输送部分，用于通过脉管系统使其可视化。具有光输送部分的导丝还能够照射导管的远端，以将导管放置在冠状血管中而不使用透视。

摘要： A covered stent (18) includes a generally tubular stent body (16) having inner and outer stent body surfaces (26, 24). A sleeve of porous material (20) encloses the stent body and has inner and outer portions (40, 42) opposed to the inner and outer stent body surfaces. A therapeutic agent is located along the stent body, the agent being diffusible through the material. A diffusion barrier (30) is located between the inner material portion and the agent along the stent. The diffusion barrier prevents passage of at least a significant amount the agent through the inner portion of the sleeve of porous material. A diffusion restrictor (32) is located between the outer portion of the sleeve of porous material and the agent along the stent. The diffusion restrictor permits passage of the agent through the inner material portion at a therapeutic level.

摘要： A stent, having openings, is mounted onto a mandrel. An agent-containing film is applied onto the stent and the two are pressed against one another so that at least a portion of the film is pressed at least partially into the openings. The film is adhered to the stent. Any excess film is removed to create a stent/film combination which is removed from the mandrel and enclosed within a sleeve of porous material to create a covered agent-eluting stent.

摘要： An electrosurgical probe is configured to deliver power to tissue. A value of a parameter (e.g., impedance or temperature) associated with a particular probe design is determined. If the value of the parameter is within a range of values that has been predetermined for the particular probe design, the probe is treating tissue in a desired manner (e.g., ablation or shrinkage). If the value of the parameter is outside the range, power is delivered to the probe according to an algorithm having a pulsed profile including portions of low power and portions of high power. When the value is impedance, and the probe is in an ablative mode, a control module of the probe is configured to limit tissue necrosis. When the probe is in a non-ablative mode, power can be delivered to the probe according to a second algorithm.
