Non-sheath based medical device delivery system
First Claim
1. A medical device deployment system comprising:
- a resilient collet;
a closing member in cooperative engagement with the collet;
an elongated tubular guide structure having a proximal end and a distal end, wherein the distal end is attached to a portion of the collet; and
a retraction member having a proximal end and a distal end, the distal end being attached to the closing member and the proximal end exiting said proximal end of the elongated tubular guide structure and wherein actuation of the retraction member moves the closing member to a first position and actuating the retraction member in an opposite direction moves the closing member to a second member.

Abstract
A non-sheath based medical device delivery system is provided including an elongated tubular guide body having a distal end fixedly attached to a resilient collet with a longitudinal opening to receive a medical lead or other device. The collet may be opened by actuating a retraction member to cause the closing member to slide proximally along the collet shaft, allowing the collet to maintain a normally open position. With the collet closed, the device may be advanced to a desired internal body location by advancing the guide body. The majority of the device body will be exposed, running alongside the guide body, allowing any sensors or electrodes located on the device body to be fully operational during the implantation procedure. The delivery system may be removed by opening the collet, to slidably disengage from the device body.
