摘要： A heat exchange catheter has a catheter body with a working fluid supply lumen extending therethrough, and terminating in a helical heat exchange tube that exits the body and extends proximally back along the catheter body. Working fluid flows through the heat exchange tube to exchange heat with the central venous system of a patient when the catheter body is properly placed in the patient.

摘要： Catheters adapted to exchange heat with a body fluid flowing through a body conduit employ helical elongate lumens for heat transfer with the body fluid. The helical elongate lumen of a catheter forms multiple turns extending longitudinally of a portion of the catheter with the turns each being bonded to the catheter along a fraction of the length of the turn. The length of the lumen and its orientation in each turn has the lumen otherwise displaced over a major portion of its length from the elongate body. The turns of the helical lumen can be arranged in sets having different lengths to encounter all areas of the flow. One or more infusion lumens may also extend to an infusion port or ports. The helical elongate lumen is defined by an elongate, thin-walled element. This lumen is in fluid communication with a heater/chiller supplying a working fluid for heat transfer through the wall of the elongate element defining the helical elongate lumen. A proximal hub may be associated with the catheter to establish at least one suture anchor and to receive the heater/chiller flow through input and output lumens associated with the catheter and in fluid communication with the helical elongate lumens. The elongated lumens may also be arranged in non-helical arrangements such as in a semi-circular configuration, a figure-eight loop configuration or a random loop configuration.

摘要： An intravenous catheter system (apparatus and method) for controlling patient temperature includes a generally tubular elongate body, a heat exchange element through which a heat exchange fluid circulates, and an inflation element or irregular surface positioned within the heat exchange element for promoting mixing of the circulating heat exchange fluid. The heat exchange element and inflation element preferably include inflatable balloons. The catheter preferably has two to four balloons having a substantially straight configuration, each balloon containing an inner balloon inflation element having a substantially spiral configuration. The catheter also preferably has at least one infusion lumen for providing access to the patient's blood and a guidewire lumen to accommodate a guidewire. The catheter is used in conjunction with a heat/cool system to cool a hyperthermic patient as quickly as possible, to warm a hypothermic patient as quickly as possible or to maintain normothermia.

摘要： Some embodiments of an endoluminal prosthesis comprise a graft having a first end and a second end, a first stent positioned at a first end of the graft, the first stent comprising a plurality of proximal apices and a plurality of distal apices, a second stent positioned axially adjacent to the first stent comprising a plurality of proximal apices positioned at a first end of the second stent. In some embodiments, the first stent can be partially covered by the graft such that the proximal apices of the first stent are not covered by the graft. The distal apices of the first stent can be positioned approximately on a first or a second plane offset from the first plane. The second stent can be positioned relative to the first stent such that the plurality of proximal apices of the second stent are spaced apart from the plurality of distal apices of the first stent. Further, one or more of the proximal apices of the second stent can be positioned approximately on a third or a fourth plane. The distal apices of the first stent can be circumferentially offset from the proximal apices of the second stent.

摘要： Methods for the treatment of ischemic limbs. An energy source, which will typically be a laser energy source deployed through an optic fiber, is deployed subcutaneously to a site of ischemic skeletal muscle. At the site, a plurality of channels are preferably systematically formed with an appropriate amount of activated energy, which in turn can facilitate the restoration of blood flow through new blood vessel formation. Optionally, a needle or cannula can be deployed in conjunction with the energy source to help facilitate the formation of channel formation and/or deliver a therapeutic agent at the sight of channel formation. A sheath may also be utilized to house the optic fiber and deliver a therapeutic agent.
