Method for using deformable medical implant

摘要

The present invention comprises an implantable subcutaneous port for anchoring a transcutaneous treatment component. The implantable subcutaneous port comprises a body portion and one or more frangible lines formed within the body portion. The body portion is adapted for receiving the transcutaneous treatment component beneath the point of entry into the physiology of a patient and routing the transcutaneous treatment component. The body portion is produced from a deformable material and has an area footprint and defines a support wall through which the transcutaneous treatment component enters the body portion. Fracturing the one or more frangible lines formed within the body portion enables removal of the body portion from the physiology of a patient through a transcutaneous opening defining an area of less than thirty percent of the area footprint of the body portion.

主权项

1. A method for removing a subcutaneously implanted port, designed for anchoring a transcutaneous treatment component when in use, from a subcutaneous implantation site, the method comprising the steps of:
(a) removing the transcutaneous treatment component from the port at a transcutaneous skin opening adjacent the port, wherein the port comprises:
(i) a device body portion having a passageway therethrough comprising a passageway entrance and a support wall for receiving the transcutaneous treatment component and for subcutaneously routing the transcutaneous treatment component to a location distal of the implantation site, the device body portion being produced from a deformable material and having an assembled area footprint; and(ii) one or more frangible lines formed within the device body portion, a fracture of which enables in situ disassembly of the device body portion into one or more device body pieces sized in at least one dimension for removal from the physiology of a patient through the transcutaneous skin opening; (b) inserting a retrieval implement through the transcutaneous skin opening; (c) grasping the device body portion with the retrieval implement at or near one of the frangible lines; (d) applying a force sufficient to fracture the one or more frangible lines thereby sectioning the device body portion into the one or more device body pieces sized in at least one dimension for removal through the transcutaneous skin opening; and (e) pulling the one or more device body pieces through the transcutaneous skin opening.
