Abstract
A tethering feature includes an elongate break-away member and a base, and forms a proximal end of an implantable medical device housing. A tether attachment zone of the break-away member extends between break-away member ends, and the base includes a pair of supports, wherein each end of the break-away member is wrapped around a corresponding support. A delivery catheter tether may be attached to the device tethering feature by passing a looped portion of the tether around the tether attachment zone. The device may be untethered from the catheter by applying a pull force through the attached tether, while a distal end of a shaft of the catheter, which abuts the device proximal end, provides a back-up force, the pull force unwrapping each end of break-away member from the corresponding base support.
