Abstract
A therapeutic delivery device that provides a controlled release of high doses of a therapeutic agent in a local area, sustains the high dose controlled release with a percutaneous port for refilling the device, and is versatile for use with multiple types of therapeutic agents and/or implant systems. A rate determining/controlled release membrane is used to decrease the molecular mobility of the therapeutic compounds thereby controlling the therapeutic release profile. The therapeutic delivery device includes a body defining an internal reservoir for receiving a therapeutic agent and including a first membrane for providing a controlled release of the therapeutic agent to the surgical site, a port in fluid communication with the reservoir, a sleeve configured to encapsulate the body, and a rigid housing configured to support the body and a portion of the sleeve, the rigid housing configured to release the body and the sleeve after the body and the sleeve are anchored position relative to the surgical site.
