Deformable medical implant
First Claim
1. An implantable subcutaneous medical device for anchoring an elongated transcutaneous treatment component that, in use, extends from outside a patient'"'"'s skin, through a transcutaneous skin opening sized to just accommodate the treatment component at a point of entry into the physiology of a patient, through the implanted medical device positioned at an implantation site, and then to a desired internal location in the patient'"'"'s body distal of the implanted medical device, the device comprising:
- a) a device body portion having a passageway therethrough comprising a passageway entrance and 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; and
,b) one or more frangible lines formed within the device body portion, the 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 the patient 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.

24. An implantable subcutaneous medical device for anchoring an elongated transcutaneous treatment component that, in use, extends from outside a patient'"'"'s skin, through a transcutaneous skin opening sized to just accommodate the treatment component at a point of entry into the physiology of a patient, through the implanted medical device positioned at an implantation site, and then to a desired internal location in the patient'"'"'s body distal of the implanted medical device, the device comprising:
-
a) a device body portion having a passageway therethrough comprising a passageway entrance and 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 body of a patient and applying force results in fracturing the frangible line along the continuous path enabling removal of the device body portion from the body of the patient through a transcutaneous skin opening defining an area of less than thirty percent of the assembled area footprint.

25. An implantable subcutaneous medical device comprising a device body portion as follows:
-
a) said device body portion comprises at least two wall sections transverse relative to one another, the wall sections together defining a device interior region, further wherein 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 frangible lines causes in situ disassembly of the device body portion into one or more device pieces sized in at least one dimension for removal from a subcutaneous implantation site in a patient through a minimally-sized removal incision in the patient'"'"'s skin that is smaller than a dimension of the device body portion along any axis prior to disassembly of the device body portion. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. An implantable subcutaneous medical device with a passageway therethrough for accommodating an elongated transcutaneous treatment component that, in use, extends from outside a patient'"'"'s body, through a skin opening, into and through the medical device positioned at an implantation site, and then to an internal body location, the medical device comprising:
- a device body portion and one or more frangible lines formed within the device body portion, whereby, at the completion of an extended period in use in a patient'"'"'s body, the device body portion can be disassembled in situ along the frangible line(s) into device pieces that are sized and/or dimensioned for removal from the implantation site through a skin opening that is smaller than the size of an incision originally needed for implanting the medical device.
