    摘要： A non-rigid tether extends distally from an electrode of a medical electrical lead body coupling a tissue anchor to the lead body. The tissue anchor includes a surface to receive a push force from an insertion tool adapted to insert the anchor within a segment of tissue so that the electrode is held in close proximity to the tissue.

    摘要： Curves and dynamic shapes are imparted in distal segments of medical instruments e.g., catheters, through use of a temperature-activated actuator coupled to distal segment of the instrument body. The actuator comprises includes members extending side-by-side in substantially a common plane and configured to move in opposite directions when independently activated. A first heating device is coupled to a first actuator member and configured to deliver thermal energy to the first actuator member to activate the first actuator member and cause the first actuator member to move the distal segment in a first direction. A second heating device is coupled to a second actuator member and configured to deliver thermal energy to the second actuator member to activate the second actuator member and cause the second actuator member to move the distal segment in a second direction opposed to the first direction.

    摘要： A medical electrical lead with a tip-ring assembly optimized to resist damage during extraction. The lead includes an elongated plastic tube and at least two elongated conductors mounted in the plastic tube. A tip-ring assembly is mounted to the distal end of the tube, the tip-ring assembly including a ring electrode coupled to one of the conductors, a tip electrode located distal to the ring electrode and coupled to another of the conductors and two molded plastic components separately fabricated of a plastic harder than the plastic tube, adhered to one another and together defining a circumferential groove in which the ring electrode is located and mechanically coupled to the tip electrode. The tip electrode may be provided with a proximally extending electrode shank covered by a tine sleeve which is fabricated of a plastic softer than the molded plastic components and is adhered to more distally located molded plastic component. The more distally located molded plastic component preferably overlaps the electrode shank to provide a stronger structure.

    摘要： An arrangement for introducing and implanting the electrode(s) of an endocardial implantable cardiac lead at a cardiac implantation site within a heart chamber or vessel. An elongated guide body formed of flexible material and extending between a guide body proximal end and a guide body distal end is advanced transvenously to position the guide body distal end in relation to the cardiac implantation site. A guide body tracking mechanism is coupled with the lead distal end for receiving and slidingly engaging the guide body to allow the cardiac lead to be advanced along the guide body until the electrode is positioned at the cardiac implantation site. A pusher mechanism formed of an elongated pusher body of flexible material extends between a pusher body proximal end and a pusher body distal end and has a cardiac lead engaging mechanism for engaging the cardiac lead at or adjacent the distal lead end. The pusher body has sufficient column strength to be advanced alongside the guide body and lead body with the cardiac lead engaging mechanism engaging and slidingly advancing the guide body tracking mechanism and the cardiac lead distally along the guide body to thereby allow the cardiac lead to be advanced along the guide body until the electrode is positioned at the cardiac implantation site. The lead body is released from the lead engaging mechanism and fixed, if the lead includes a fixation mechanism. The pusher mechanism is retracted by retraction of the pusher body.
