Abstract
Abstract This invention relates generally to an implantable subcutaneous access device for performing an endoscopic operative procedure, and the method of using the subcutaneous access device. The subcutaneous access device is comprised of a portal sleeve, the portal sleeve preferably being angulated to provide an angulated port of entry for a surgical device through cutaneous layers of the body. A subcutaneous flange is connected to the portal sleeve in order to secure the subcutaneous access device under the cutaneous layer. An access flange which may function as a surgical mat is also connected to the portal sleeve. The method of using the subcutaneous access device consists of forming a transdermal incision, inserting the subcutaneous access device into and through the incision, and inserting and manipulating a surgical device through the port of entry to thereby perform a surgical procedure.
