Method for using deformable medical implant
First Claim
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.

Abstract
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.

29. A method for removing from a subcutaneous implantation site in a patient a subcutaneously implanted medical device, designed for anchoring an elongated transcutaneous treatment component that, in use, extends from outside skin of the patient, through a transcutaneous skin opening sized to just accommodate the treatment component at a point of entry into the patient, through the implanted medical device positioned at an implantation site, and then to a desired internal location in the patient distal of the implanted medical device, the device comprising:
-
a) a device body portion having a passageway therethrough comprising a passageway entrance and a support wall for receiving the transcutaneous treatment component beneath the point of entry and for subcutaneously routing the transcutaneous treatment component to the desired internal location, the device body portion being produced from a deformable material and having an assembled area footprint; b) at least a frangible line extending along a continuous path between an outer perimeter of the device body portion and the annular support wall; and c) at least one device gripping element disposed on the device body portion at a point adjacent to the frangible line, whereby gripping the gripping element from a point external to the patient and applying force results in fracturing the frangible line along the continuous path enabling removal of the device body portion from the patient through a transcutaneous skin opening defining an area of less than thirty percent of the assembled area footprint; wherein the method comprises using the at least one device gripping element to fracture the frangible line causing in situ disassembly of the device body portion, and thereafter removing the disassembled device body portion from the implantation site.

30. A method for removing from a subcutaneous body implantation site in a patient an implanted subcutaneous medical device comprising a device body portion as follows:
-
a) said device body portion comprises at least two transverse wall sections that are transverse relative to one another, the two transverse wall sections together defining a device interior region, further wherein the two transverse wall sections include apertures extending through the wall sections into the device interior region such that an elongated transcutaneous treatment component can be passed through the aperture of one wall section, through the device interior region, and out through the aperture of the other wall section; and
, b) said device body portion further comprises one or more frangible lines formed within the device body portion such that fracturing the device body portion along the one or more frangible lines causes in situ disassembly of the device body portion into one or more removably-sized device body pieces that are sized in at least one dimension for removal from the subcutaneous implantation site in the patient through a minimally-sized removal incision in the skin of the patient that is smaller than a dimension of the device body portion along any axis prior to disassembly of the device body portion;wherein the method comprises fracturing the device body portion along the one or more frangible lines into the removably-sized device body pieces and removing the device body pieces from the implantation site. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)

45. method for removing from an implantation site in a patient an implanted subcutaneous medical device with a passageway therethrough for accommodating an elongated transcutaneous treatment component that, in use, extends from outside the body of the patient, through a skin opening having a first size, into and through the medical device positioned at the implantation site, and then to an internal body location, the medical device comprising:
- a device body portion that is longer along a device-portion long axis than in any other direction and has one or more frangible lines formed within the device body portion, whereby, at the completion of an extended period in use in the patient'"'"'s body, the device body portion can be disassembled in situ along the frangible line(s) into removably-sized device body pieces that are sized or dimensioned for removal from the implantation site through a skin opening having a second size that is smaller than a length of the device body portion along the device-portion long axis;
wherein the method comprises fracturing the device body portion along the frangible lines into the removably-sized device body pieces and removing the device body pieces from the implantation site through the skin opening having the second size. - View Dependent Claims (46)
