    摘要: A method and apparatus are provided for withdrawing an indwelling over-the-wire catheter from an indwelling guidewire in which the guidewire is of a conventional length and is maintained in its indwelling position as the catheter is withdrawn. The position of the guidewire is maintained by constraining a segment of the catheter shaft and its included guidewire in a non-linear configuration such that the guidewire remains in its position as the catheter is withdrawn. The invention may be used to perform catheter exchanges without requiring the use of exchange wires, extension wires, rapid exchange catheters or special devices to connect the guidewire to the guide catheter.

    摘要: The invention relates to a catheter device and method of use for exchanging a catheter having a full-length guidewire lumen over a conventional-length guidewire without the use of a guidewire extension or an exchange wire. The catheter device includes an elongated shaft defining an inflation lumen and a guidewire lumen extending longitudinally throughout its length, and a hydraulic exchange lumen extending from the proximal end of the shaft and terminating proximal the distal end of the shaft, wherein the hydraulic exchange lumen is in fluid communication with the guidewire lumen. A balloon is coupled to the distal section of the shaft and is in fluid communication with the inflation lumen. A flow guiding member is disposed within the guiding catheter and functions to redirect the distal flow of pressurized fluid traveling through the hydraulic exchange lumen in a proximal direction through the guidewire lumen.

    摘要: Various fixation techniques for implantable medical device (IMDs) are described. In one example, an assembly comprises an IMD; and a set of active fixation tines attached to the IMD. The active fixation tines in the set are deployable from a spring-loaded position in which distal ends of the active fixation tines point away from the IMD to a hooked position in which the active fixation tines bend back towards the IMD. The active fixation tines are configured to secure the IMD to a patient tissue when deployed while the distal ends of the active fixation tines are positioned adjacent to the patient tissue.

    摘要: A delivery system assembly includes an elongate outer tube, an elongate inner member extending within a lumen of the outer tube, and an articulation sheath surrounding the outer tube between a handle of the assembly and a distal-most portion of the outer tube. The outer tube is longitudinally moveable within the sheath; and an inner diameter of the sheath is preferably smaller than that of the handle and the distal-most portion of the outer tube. Navigation of the assembly through a venous system, for deployment of an implantable medical device, is facilitated by deflection of the sheath, to orient a distal-most portion of the outer tube, within which an entirety of the medical device is contained/loaded, and by subsequent advancement of the distal-most portion, with respect to the sheath, to move the distal end of the inner member, along with the contained/loaded device into proximity with a target implant site.

    摘要: A catheter wherein the "effective over-the-wire" length is adjustable. The catheter includes an elongated inflation shaft having a longitudinal inflation lumen, an extension shaft disposed distal to the inflation shaft and through which the inflation lumen is continued, a balloon element disposed at the distal end of the extension shaft and in fluid communication with the inflation lumen, a guidewire shaft having a longitudinal guidewire lumen which extends from the distal end of the balloon member, through the balloon member and the extension shaft, to the proximal end of the extension shaft, and a telescoping portion. The telescoping portion comprising first and second telescoping tubes which are slidably mounted on the inflation shaft and the extension shaft. The first and second telescoping tubes are sized so that the first telescoping tube can be retracted into the second telescoping tube. The extension shaft is sized so that it can be retracted into the first telescoping tube. The effective "over-the-wire length" of the telescoping balloon catheter can be reduced by retracting the first telescoping tube and the extension tube into the second telescoping tube. In another embodiment, the telescoping portion comprises three telescoping tubes, which results in a greater reduction of the effective "over-the-wire length."

    摘要: A laterally attachable and detachable tool for manipulating a guidewire includes a cylindrical body that terminates in a collet. A nut is threaded to the collet and can be tightened to draw the collet arms inwardly. The body and the nut each include a lateral slot of a width to receive the guidewire. The slot in the nut is registrable with the slot in the body to form a continuous slot, receptive to the guidewire, along the length of the tool.

    摘要: A delivery system assembly includes an outer tube, an inner member, extending within a lumen of the outer tube, and a deflectable shaft, extending within the outer tube lumen and around the inner member; the tube and inner member are longitudinally moveable with respect to the shaft, and a distal end of the inner member is located distal to the shaft within the tube lumen. A medical device can be loaded into the tube lumen, along a distal-most portion of the tube, and contained between the inner member and a distal opening of the tube lumen. Deflecting the shaft orients the distal-most portion for navigation of the assembly, and, when the distal end of the inner member is engaged within the tube lumen, distal movement of the tube, with respect to the shaft, causes similar distal movement of the inner member and the loaded medical device toward an implant site.

    摘要: A delivery system assembly includes an elongate inner member that extends distally through a lumen of an elongate outer tube of the assembly; the outer tube is moveable relative to the inner member between first and second positions to deploy an implantable medical device that is held within the outer tube lumen. The inner member may include a flared distal end that abuts, and preferably conforms to, the proximal end of the device, when the device is held within the outer tube lumen. The assembly further includes a stability sheath that surrounds a limited length of the outer tube, in proximity to the handle, to provide an interface for both an operator, who handles the assembly, and for an introducer sheath that provides passage for the assembly into the venous system, so that movement of the outer tube is not hindered by either during device deployment.
