Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
46 words
A tissue biopsy system comprising: a wire having an anchor at a distal end thereof; an excision instrument having a fixed cutting blade adapted to travel over the wire to a tissue region marked by the anchor; and an over-the-wire tissue harvester having a rotating hoop.
Claim 2
Dependent Claim
46 words
A tissue biopsy system comprising: a wire having an anchor at a distal end thereof; an excision instrument having a fixed cutting blade adapted to travel over the wire to a tissue region marked by the anchor; and an over-the-wire tissue harvester having a rotating hoop.
Claim 3
Dependent Claim
19 words
A system as in claim 1 , wherein the cutting blade of the excision instrument is a triangular blade.
Claim 4
Dependent Claim
22 words
A system as in claim 2 , wherein the hoop of the tissue harvester is adapted to be activated with electrical energy.
Claim 5
Dependent Claim
19 words
A system as in claim 1 , wherein the wire is scored to allow position determination under radiographic imaging.
Claim 6
Independent Claim
104 words
A method for biopsying breast tissue, said method comprising: placing a wire at a target location in the breast tissue under radiographic guidance; measuring the depth of the target location using a template; selecting an excision instrument based on the measurement; advancing the excision instrument over the wire to form a path to the biopsy site; withdrawing the excision instrument through the path; advancing a tissue harvester over the wire; rotating a hoop on the tissue harvester to excise a cylinder of tissue at the biopsy site; withdrawing the tissue harvester from the path; and removing the cylinder of tissue from the biopsy site.
