Deformable medical implant

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.

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.
