First Claim
Patent Images
1. A method for deploying an anchor sleeve onto an elongate body of an implantable medical device, the method comprising:
- inserting a distal portion of an introducer shaft into a body of a patient, the inserted distal portion providing percutaneous access to an implant site through a lumen of the shaft;
simultaneously inserting the body of the device through the lumen of the introducer shaft and through a lumen of a deployment tool, the tool being mounted around a proximal portion of the introducer shaft;
simultaneously advancing the inserted body of the device through the lumen of the introducer shaft, and through a lumen of the anchor sleeve, to the implant site, the anchor sleeve being mounted around the proximal portion of the introducer shaft; and
pulling the introducer shaft proximally, out from the body of the patient, while holding the deployment tool in place, relative to the advanced body of the device;
wherein the held deployment tool contacts the anchor sleeve to hold the anchor sleeve in place, relative to the advanced body of the device, while the introducer shaft is pulled proximally; and
after the introducer shaft has been pulled out from the body of the patient, the anchor sleeve is deployed onto the advanced body.

Abstract
An introducer assembly that may be employed to implant a medical device includes an introducer shaft, and an anchor sleeve and a deployment tool mounted on the shaft. According to some methods, the sleeve is deployed onto an elongate body of the medical device, after the body has been advanced through a lumen of the introducer shaft and to an implant site within a body of a patient, by pulling the introducer shaft proximally, out from the body of the patient, while holding the deployment tool in place, relative to the advanced body of the device.
