Abstract
A removal tool uses magnetic attraction to guide the removal tool toward an implantable device subcutaneously implanted in subcutaneous tissue of a host and to remove the implantable device from the host. The removal tool may include first and second lever members that are pivotably connected together, and the first and second lever members include a pair of jaw members configured to move between open and closed positions to grasp the implantable device. The first jaw member may include a magnet to magnetically attract and couple to an implantable device implanted subcutaneously below a skin surface of a host.
Claims31
A method of removing an implantable device implanted subcutaneously in a tissue pocket below a skin surface of a host, the method comprising:
- (a) placing a magnet on the skin surface above the implantable device, wherein the magnet attracts the implantable device such that an outline of the implantable device is visible on the skin surface;
- (b) while the magnet is on the skin surface above the implantable device and the attraction of the implantable device and the magnet is creating the outline of the implantable device, creating an incision in the skin surface at one end of the outline of the implantable device;
- (c) removing the implantable device out of the tissue pocket and through the incision.
A method of removing an implantable device implanted subcutaneously in a tissue pocket below a skin surface of a host, the method comprising:
- placing a magnet on the skin surface above the implantable device, wherein the magnet attracts the implantable device;
- moving the magnet toward an incision created in the skin surface, wherein movement of the magnet toward the incision moves the implantable device toward the incision;
- and
- moving the magnet past the incision, wherein movement of the magnet past the incision moves the implantable device out of the tissue pocket and through the incision.
A removal tool comprising:
- a first lever member comprising a first handle at a first end of the first lever member and an actuator at a second end of the first lever member;
- a second lever member comprising a second handle at a first end of the second lever member and a first jaw member at a second end of the second lever member;
- and
- a rod comprising a contact portion at a first end of the rod and a second jaw member at a second end of the rod;
- wherein the actuator of the first lever member is configured to contact the contact portion of the rod;
- wherein the first lever member is pivotably coupled to the second lever member at a joint such that the first and second handles are configured to move between an open position in which the first and second handles are relatively far from each other and a closed position in which the first and second handles are relatively close to each other;
- wherein movement of the first and second handles from the open position to the closed position is configured to move the second jaw member in a direction of a longitudinal axis of the rod from a retracted position in which the second jaw member is displaced from the first jaw member to an extended position in which the second jaw member is positioned opposite the first jaw member.
A method of using a removal tool, the method comprising:
- moving first and second handles of the removal tool from an open position in which the first and second handles are relatively far from each other to a closed position in which the first and second handles are relatively close each other, wherein the first handle is at a first end of a first lever member, an actuator is at a second end of the first lever member, the second handle is at a first end of a second lever member, a first jaw member is at a second end of the second lever member, and the actuator is contact with a contact portion at a first end of a rod;
- wherein movement of the first and second handles from the open position to the closed position moves a second jaw member at a second end of the rod in a direction of a longitudinal axis of the rod from a retracted position in which the second jaw member is displaced from the first jaw member to an extended position in which the second jaw member is positioned opposite the first jaw member.
A method for removing an implantable device implanted subcutaneously in a tissue pocket below a skin surface of a host, the method comprising:
- (a) inserting a first jaw member of the removal tool into an incision in the skin surface;
- (b) moving the first jaw member to a position adjacent to a first side of the implantable device, wherein moving the first jaw member to the position adjacent to the first side of the implantable device comprises dissecting tissue attached to the first side of the implantable device;
- (c) after moving the first jaw member to the position adjacent to the first side of the implantable device, moving a second jaw member of the removal tool to a position adjacent to a second side of the implantable device, wherein the second side of the implantable device is opposite the first side of the implantable device, moving the second jaw member to the position adjacent to the second side comprises moving first and second handles of the removal tool from an open position in which the first and second handles are relatively far from each other to a closed position in which the first and second handles are relatively close each other, moving the first and second handles from the open position to the closed position causes the second jaw member to move from a retracted position to an extended position, movement of the second jaw member from the retracted position to the extended position dissects tissue attached to the second side of the implantable device, and the first and second jaw members grasp the implantable device when in the positions adjacent to the first and second sides of the implantable device, respectively;
- and
- (d) removing the first and second jaw members and the implantable device grasped between the first and second jaw members out of the tissue pocket and through the incision.
