Transponder strings
First Claim
1. A method of inserting a surgical guide into tissue, the method comprising:
- loading a needle with an absorbable suture having;
an anchoring mechanism at a proximal end of the absorbable suture, anda plurality of transponders attached along a length of the absorbable suture;
inserting the needle into tissue until a proximal end of the needle is at an area of interest within the tissue;
moving the absorbable suture towards the proximal end of the needle so that the anchoring mechanism exits the needle;
removing the needle such that the anchoring mechanism remains attached to the area of interest and at least some of the plurality of transponders are positioned at varying positions between a surface of the tissue and the area of interest;
cutting the absorbable suture to createan embedded portion including the at least some of the plurality of transponders anda cut portion including a remainder of the absorbable suture not in the embedded portion; and
removing the cut portion of the absorbable suture such that the at least some of the plurality of transponders coupled to the embedded portion of the absorbable suture remain embedded in tissue.

Abstract
A transponder string comprising multiple transponders is configured for injection into human tissue. In one embodiment, the transponders are sized to move through a needle for injection into the human tissue. Positions of the transponders with reference to one another may be maintained by coupling the transponders via a filament, adhesive backed substrate, shrink tubing, and/or any other suitable substrate. The transponders are configured to transmit data to a mobile computing device, e.g., a wand, smart phone or wireless tablet positioned outside the human tissue such that positions of the transponders are determinable, e.g., during an excision surgery.

2. A method of inserting a surgical guide into tissue, the method comprising:
-
loading a needle with an absorbable suture having an anchoring mechanism at a proximal end of the absorbable suture and a transponder attached at a distal end of the absorbable suture; inserting the needle into tissue until a proximal end of the needle is at an area of interest within the tissue; moving the absorbable suture towards the proximal end of the needle so that the anchoring mechanism exits the needle; and removing the needle such that the anchoring mechanism remains attached to the area of interest, a central portion of the absorbable suture passes through tissue towards a surface of the tissue, and the transponder is positioned at below the surface of the tissue such that the transponder is detectable by an electronic reading device above the surface of the tissue. - View Dependent Claims (3)

4. A surgical guide comprising:
-
a biologically absorbable filament having an anchoring mechanism on an attachment end of the filament, the anchoring mechanism configured to secure to mammalian tissue such that the filament is held within the mammalian tissue at or near an area of interest and the filament is adapted to extend through the mammalian tissue towards a surface of the mammalian tissue; and a first transponder attached to the filament, the first transponder configured to transmit data indicating a unique identifier of the first transponder to a handheld mobile computing device such that a position of the first transponder within the mammalian tissue is determinable; wherein the biologically absorbable filament and the first transponder are sized to move through a needle for injection into the mammalian tissue. - View Dependent Claims (5, 6)
