摘要： A device for removing from a patient a previously implanted elongated structure, such as a cardiac lead. The device includes a gripping member having a receiving portion and a capturing portion. The receiving portion defines an eyelet for receiving a length of the elongated structure. The capturing portion is movable relative to at least the eyelet of the receiving portion, and is dimensioned such that upon relative movement, the receiving portion is constrictable around a length of the elongated structure length. The receiving portion may comprise a wire and the capturing portion may comprise a collar, wherein at least a portion of the collar is movable over the eyelet to constrict the wire around the length of the elongated structure length received in the eyelet.

摘要： A device for removing from a patient a previously implanted elongated structure, such as a pacemaker lead or a defibrillator lead, that may be encapsulated in biological tissue of the patient. In one form, the device comprises a sheath member having an inside dimension greater than the outside dimension of the elongated structure, and a gripping member positioned about the sheath member. The gripping member has a longitudinal passage extending substantially therethrough, which longitudinal passage is dimensioned to encircle at least a portion of the elongated structure. A proximal portion of the gripping member may extend outwardly beyond the proximal end of the elongated structure and outwardly of at least the vascular system of the patient. The gripping member may comprise a first configuration having a first diameter that is greater than the outside dimension of the elongated structure, and a second configuration having a second diameter that is substantially the same as the outside dimension of the elongated structure.

摘要： An introducer apparatus (10) comprising a pair of co-extending splittable introducer sheaths (11), (12) is disclosed. The unique properties (pushability, torqueability, length, shape, etc.) of the individual introducer sheaths yields an introducer apparatus with the additional navigational flexibility to reach a remote target that whose access would be more difficult or impossible with a single introducer sheath. One embodiment include a coaxial pair of introducer sheaths made of molecularly oriented (non-isotropic) polytetrafluoroethylene PTFE which are used for placement of a pacemaker or defibrillator lead into the coronary sinus. In this embodiment, the first introducer sheath (11) is introduced over a wire guide into ostium of the coronary sinus, which represents the first target site. The outer introducer sheath includes preformed bends (20) to facilitate passage through the vasculature. A second introducer sheath (12), which includes a curved distal portion (17), is introduced through the first introducer where it extends from the distal end of the outer introducer sheath to access the second, ultimate targer site, such as a coronary artery branching from the coronary sinus. After the pacemaker lead has been placed, both sheaths are split and removed from the patient.
