Abstract
A fixation member configured to anchor an implantable medical device within a patient is attached to an implantable medical device by introducing at least a portion of the fixation member in a tube mechanically connected to the medical device, and plastically deforming the tube in order to pinch the fixation member within a hollow space of the tube.
Claims15
A method comprising:
- positioning a fixation member for a medical device in a hollow space defined by a tube configured to be mechanically connected to the medical device, the tube comprising a first end, a second end, a side surface extending between the first end and the second end, and a central longitudinal axis;
- and
- applying a force directed radially toward the central longitudinal axis of the tube to the side surface of the tube to plastically deform the tube to pinch the fixation member within the hollow space.
An attachment mechanism for a fixation member of an implantable medical device, the attachment mechanism comprising a tube, wherein the tube comprises a first end, a second end, a side surface extending between the first end and the second end, and a central longitudinal axis, and wherein the fixation member comprises a first portion and a second portion,
- wherein the first portion is configured to extend within the tube at a substantially constant outer surface diameter for at least the length of the tube and the second portion is configured to expand to push against tissue, and
- wherein the tube is configured to be connected to the implantable medical device and to be plastically deformed by a force directed radially toward the central longitudinal axis of the attachment mechanism and applied to the side surface to pinch the first portion of the fixation member within a hollow space defined by the tube.
