Subcutaneous implant removal device
A subcutaneous implant removal device designed to work with a variety of cylindrical implants. The implant removal device comprises a non-planar base. The non-planar base is dimensioned to be placed onto the epidermal surface of a patient's skin. The base has a proximal end and a distal end. When placed on the patient's skin, the proximal end slopes upward while the distal end slopes downward along the patient's skin. The subcutaneous implant removal device also includes a pinnacle. The pinnacle extends upward from the non-planar base and has a front face and a rear face. The front face of the pinnacle is dimensioned to receive a force from a thumb of a clinician, holding the removal device in place on the patient's skin during use. A method for removing a subcutaneous implant is also provided.
1 . A method of removing a subcutaneous implant, comprising:
locating an elongated subcutaneous implant below a skin of a patient;
providing an implant removal device, comprising:
a non-planar base having a proximal end and a distal end, wherein the proximal end slopes upward at an angle of between 10 and 40 degrees, inclusive while the distal end slopes upward at an angle of between 5 and 15 degrees, inclusive and
a pinnacle extending upward from the non-planar base intermediate the proximal end and the distal end, with the pinnacle having a front face and a rear face; placing the non-planar base of the implant removal device onto the skin of the patient such that the proximal end of the non-planar base is proximate a leading end of the elongated subcutaneous implant;
making an incision through the skin of the patient above the leading end of the elongated subcutaneous implant, down to a depth of the leading end;
applying a downward force to the implant removal device while also applying a force against a trailing end of the elongated subcutaneous implant;
urging the leading end of the elongated subcutaneous implant through the incision and against the proximal end of the non-planar base; and
removing the elongated subcutaneous implant from the patient.
2 . The method of claim 1 , wherein the elongated subcutaneous implant is a pharmaceutical delivery implant.
3 . The method of claim 2 , wherein
applying a downward force to the elongated implant removal device comprises a clinician pressing a thumb against the front face of the pinnacle.
4 . The method of claim 3 , wherein:
the implant removal device is fabricated from a polycarbonate material; and
the pharmaceutical delivery implant comprises a hormone suppression drug or a contraceptive.
5 . The method of claim 3 , wherein: the pinnacle further comprises:
a first arm on a first side of the non-planar base; inclusive, while the distal end of the base slopes downward at an angle of between 5 and 15 degrees, inclusive; and
the base is non-planar;
and wherein the pinnacle further comprises:
a first arm on a first side of the non-planar base;
a second arm on a second side of the non-planar base opposite the first arm; and
a bridge connecting the first arm, the second arm, and the non-planar base.
6 . The method of claim 5 , wherein:
the distal end of the non-planar base defines a concave intersection between the bridge and the non-planar base, forming an obtuse angle; and
the proximal end of the non-planar base defines a concave intersection between the front face and the non-planar base, forming an acute angle.
7 . The method of claim 3 , wherein the subcutaneous implant is placed within an upper arm of the patient.
8 . The method of claim 7 , further comprising:
imaging the upper arm of the patient before making the incision in order to verify a subcutaneous location of the subcutaneous implant.
9 . The method of claim 3 , wherein:
the subcutaneous implant defines an elongated cylindrical body;
the distal end of the non-planar base comprises an indentation dimensioned to receive the leading end of the subcutaneous implant; and
the non-planar base is between 3 cm and 6 cm in length.
