Implantable medical device delivery system
First Claim
1. A system for delivering an implantable medical device to a treatment site within a patient, comprising:
- an implantable medical device comprising a rigid body;
a delivery device comprising;
an elongated catheter shaft comprising a proximal end and a distal end, wherein the elongated catheter shaft defines a longitudinal axis extending between the proximal end and the distal end;
an expandable balloon connected to the elongated catheter shaft adjacent the distal end of the elongated catheter shaft, wherein the expandable balloon comprises a proximal region, a distal region, and an implant retaining portion disposed between the proximal region and the distal region; and
a compression element connected to the implant retaining portion of the expandable balloon, wherein the compression element is adapted to limit expansion of the implant retaining portion of the expandable balloon when the expandable balloon is at least partially inflated;
wherein the implantable medical device is connected to the delivery device such that at least a portion of the compression element and at least a portion of the implant retaining portion of the expandable balloon are disposed within a lumen defined by the rigid body of the implantable medical device, and further wherein the compression element is adapted to prevent the expandable balloon from expanding within the lumen of the rigid body of the implantable medical device.

Abstract
A system for delivering an implantable medical device to a treatment site within a patient includes an implantable medical device including a rigid body, and a delivery device. The delivery device includes an elongated catheter shaft and an expandable balloon connected to the elongated catheter shaft adjacent a distal end of the elongated catheter shaft, where the expandable balloon includes a proximal region, a distal region, and an implant retaining portion disposed between the proximal region and the distal region. The delivery device also includes a compression element connected to the implant retaining portion of the expandable balloon, where the compression element is adapted to limit expansion of the implant retaining portion of the expandable balloon when the expandable balloon is at least partially inflated. At least a portion of the compression element and the implant retaining portion are disposed within a lumen of the implantable medical device.
