    摘要： Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically, the tissue separating device includes a handle, an elongate sheath and a circular cutting blade that may extend from the distal end of the sheath upon actuating the handle. The circular cutting blade is configured to engage the tissue surrounding an implanted lead and cut such tissue in a coring fashion as the device translates along the length of the lead, thereby allowing the lead, as well as any tissue remaining attached to the lead, to enter the device's elongate shaft. The tissue separating device includes a cam mechanism at the distal portion of the sheath that allows the user of the device to more accurately control the extension and rotation of the cutting blade upon being actuated by the handle.

    摘要： Embodiments of the present invention include a laser catheter that includes a catheter body, a light guide, and a distal tip that extends beyond the exit aperture of the light guide. In some embodiments, an imaging device is disposed on the distal tip such that the imaging device is distal relative to the exit aperture of the light guide. In some embodiments, the imaging device can be gated to record images during and/or slightly beyond periods when the laser catheter is not activated.

    摘要： Embodiments of the present invention comprise a fiber optic guidewire having a hypotube with a plurality of openings that provide variable stiffness and tracking characteristics between at least one proximal segment and one distal segment of the guidewire. In some embodiments, the guidewire further comprises a mandrel disposed within the hypotube, the mandrel cooperating with the optical fibers to permit the distal end of the hypotube to be shaped as desired by a user. Methods of manufacturing and using the guidewire are also disclosed.

    摘要： A guide wire assembly includes a guide wire, an optical fiber, and an insulating coating. The guide wire has a distal end, a proximal end, and a bore extending through the wire between the distal and proximal ends. The an optical fiber also includes a distal end and a proximal end and is located within the bore of the guide wire. The optical fiber extends at least between the distal and proximal ends of the guide wire. The insulating coating is around an outside diameter of the guide wire, and is applied such that the distal ends of the guide wire and optical fiber are exposed.

    摘要： Systems and methods for separating an object such as a pacing lead from a patient tissue involve a flexible and torqueable shaft having an internal lumen sized to receive the object, and a hard separating mechanism for separating the object from the tissue. Typically the shaft and separating mechanism are advanced along or toward the object, and the separating mechanism is contacted with the tissue. The shaft is rotated to effect separation between the object and the tissue. The systems and methods are well suited for use in cardiac pacing or defibrillator lead explant procedures.
