Abstract
A fixation mechanism coupled to an implantable device body extends from a proximal portion of the body to a distal portion of the body and includes a fixation element and a push tube segment. A push tube segment of the mechanism extends proximally from the fixation mechanism to the proximal portion of the body and is adapted to deploy the mechanism.
Claims50
An implantable device, comprising:
- an elongate body including a proximal portion and a distal portion;
- a fixation mechanism formed about the body, extending from the proximal portion to the distal portion and comprising:
- a fixation segment positioned in proximity to a distal end of the fixation mechanism and including a deployable lobe,
- a push tube segment extending from the fixation segment proximally to a proximal end of the fixation mechanism, and
- an anchor fixedly coupling the fixation mechanism distal end to the body;
- and
- a lubricious interface between the body and a portion of the push tube;
- wherein the deployable lobe is deployed when the push tube segment is pushed distally.

An implantable device, comprising:
- an elongate body including a proximal portion and a distal portion;
- and
- a fixation mechanism formed about the body, extending from the proximal portion to the distal portion and comprising:
- a fixation element positioned in proximity to a distal end of the fixation mechanism, and
- a push tube segment extending from the fixation element to a proximal end of the fixation mechanism and including an internal protrusion, the protrusion forming a frictional interface between the body and the push tube segment.
2 more elements
A method for implanting a device, the method comprising the steps of:
- deploying a fixation mechanism via a push tube segment, the fixation mechanism including a fixation element, coupled to the device body in proximity to a distal portion of the body, and the push tube segment, extending from the fixation element of the fixation mechanism proximally to a proximal portion of a device body;
- and
- fixedly coupling the push tube segment to the proximal portion of the body in order to hold the fixation mechanism in the deployed position at an implant site.
