Non-sheath based medical device delivery system
First Claim
1. A medical device deployment system comprising:
- an elongated medical device configured for implantation and having a proximal end and a distal end with a first axis extending therebetween;
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 with a second axis defined therebetween, 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 position, where the collet includes a first longitudinal opening configured to receive the elongated medical device when the closing member is in the first position so that the resilient collet is in an open position and when the closing member is in the second position and the resilient collet is in a closed position the elongated medical device is retained within the first longitudinal opening so that the first axis of a portion of the elongated medical device retained by the collet is generally parallel to the second axis of the guide structure proximate the collet.

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.

41. A method of implanting an elongated medical device comprising:
-
positioning a distal portion of the elongated medical device within a collet of a deployment tool having an elongated body, such that the elongated medical device is held external to and adjacent to the tool; guiding the deployment tool to a desired location; opening the collet; retracting the tool, wherein the open collet slides along the medical device; and separating the collet from the medical device by withdrawing a proximal portion of the medical device from a longitudinal groove disposed on the collet. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48)

49. A method of implanting an epicardial lead, comprising:
-
attaching a distal portion of the epicardial lead to heart tissue; positioning a proximal portion of the epicardial lead within a collet of a deployment tool having an elongated body, such that the epicardial lead is held external to and adjacent to the tool; tunneling the deployment tool to a pocket created for holding an implantable medical device connectable to the epicardial lead; opening the collet; retracting the tool; and separating the collet from the epicardial lead by withdrawing a distal portion of the epicardial lead from a longitudinal groove disposed on the collet.
