Insertion and removal methods and apparatus for therapeutic devices
First Claim
1. An apparatus to insert an implantable therapeutic device into a patient, the apparatus extending along a longitudinal axis from a proximal end of the apparatus to a distal end of the apparatus, the apparatus comprising:
- a proximal handle; and
a distal placement portion coupled to the proximal handle and configured to hold the implantable therapeutic device, the distal placement portion comprising;
a first side having a first engagement structure at a distal end of the first side, the first engagement structure being substantially c-shaped and configured to surround at least a first portion of a proximal end region of the implantable therapeutic device;
a second, opposite side having a second engagement structure at a distal end of the second side, the second engagement structure being substantially c-shaped and configured to surround at least a second, opposite portion of the proximal end region of the implantable therapeutic device,wherein each of the first and second engagement structures comprises;
a distal-facing surface;
a proximal-facing surface opposite the distal-facing surface that extends substantially orthogonal to the longitudinal axis of the apparatus; and
an inward-facing protrusion tapering distally towards the distal-facing surface; and
at least one guide surface located proximal to the first and second engagement structures and angled obliquely relative to the longitudinal axis from the proximal end towards the distal end of the apparatus.

Abstract
Described herein is an apparatus to insert an implantable therapeutic device into a patient. The apparatus includes a proximal handle (210) and a distal placement portion (220) coupled to the proximal handle and configured to hold the implantable therapeutic device. The distal placement portion includes a first side (222) having a first engagement structure (251) at a distal end of the first side, the first engagement structure configured to surround at least a first portion of a proximal end region of the implantable therapeutic device. The distal placement portion includes a second, opposite side (224) having a second engagement structure (253) at a distal end of the second side, the second engagement structure configured to surround at least a second, opposite portion of the proximal end region of the implantable therapeutic device.
