    摘要： A steerable stylet and manipulative handle assembly especially adapted for guiding the introduction of an endocardial pacing or cardioversion/defibrillation lead or a catheter to a desired location in a patient's cardiovascular system. The steerable stylet or catheter designed to be introduced into the lumen of a lead comprises an outer, elongated tubular member of a length sufficient to extend through the length of the lead or catheter from its proximal opening to the distal end thereof, a traction element or pull wire extending generally through the length of the tubular member and within its lumen except for a predetermined distance in the distal portion thereof, and a manipulative handle coupled to the proximal ends of the tubular member and wire which may be employed with one hand to both rotate the tubular member and impart a continuously variable curve in the distal portion thereof. The distal portion of the tubular member is especially configured to be either attached to or cooperate with the distal end of the pull wire so that proximally-directed traction applied by the handle to the wire causes the distal portion of the tubular member to bend. The distal portion of the tubular member is provided with openings to allow the wire to exit and re-enter the lumen of the tubular member in the distal portion so that traction applied to the wire bows the tubular member into a curve of desired radius.

    摘要： An implantable cardioversion or defibrillation lead provided with a large surface, carbon fiber electrode. The lead takes the form of an elongated tubular braid of carbon fiber, provided with a central core of insulating plastic. Over the majority of the braid's length, it is covered by an outer sheath of insulating plastic as well, serving as a lead conductor. At its distal end, the braid is not covered, and the exposed portion of the braid serves as the electrode.

    摘要： A steerable stylet and manipulative handle assembly especially adapted for guiding the introduction of an endocardial pacing or cardioversion/defibrillation lead or a catheter to a desired location in a patient's cardiovascular system. The steerable stylet or catheter designed to be introduced into the lumen of a lead comprises an outer, elongated tubular member of a length sufficient to extend through the length of the lead or catheter from its proximal opening to the distal end thereof, a traction element or pull wire extending generally through the length of the tubular member and within its lumen except for a predetermined distance in the distal portion thereof, and a manipulative handle coupled to the proximal ends of the tubular member and wire which may be employed with one hand to both rotate the tubular member and impart a continuously variable curve in the distal portion thereof. The distal portion of the tubular member is especially configured to be either attached to or cooperate with the distal end of the pull wire so that proximally-directed traction applied by the handle to the wire causes the distal portion of the tubular member to bend. The distal portion of the tubular member is provided with openings to allow the wire to exit and re-enter the lumen of the tubular member in the distal portion so that traction applied to the wire bows the tubular member into a curve of desired radius. In use, the distal portion of the wire residing outside the lumen of the tubular member is constrained within the lumen of the lead or catheter. Traction applied by the manipulative handle to the wire is sufficient to cause the distal portion of the pacing lead to assume various angles of curvature from straight to approximately one hundred eighty degrees. The distal portion of the tubular member which bows in response to the applied traction is preferably cut out or flattened to avoid kinking. The manipulative handle may be employed with one hand to impart the desired degree of curvature while rotating the lead or catheter to direct its distal end through the venus system and into the desired site within a chamber of the heart or the coronary sinus. The ability to dynamically change the degree of curvature during advancement avoids the necessity of removing and recurving the stylet during the introduction of the lead or catheter.

    摘要： A cardiac pacing lead for endocardial use, having a pacing electrode which takes the form of a tapered, conical helix extending from the distal end of the lead. The helix is used to attach the distal end of the lead to heart tissues. The tapered shape of the helix facilitates passage of the lead through the venous system and through the tricuspid valve. Rotation of the fixation helix is accomplished by means of rotation of a coiled conductor extending the length of the lead, in conjunction with rotation of a stylet, passing down the conductor. The stylet is fixedly mounted with respect to the coiled conductor at both the proximal and distal ends of the lead.
