Abstract
Abstract A buttressing pledget is manufactured from a synthetic elastomeric material. The elastomeric material can be nonporous, radiolucent, and/or a silicone rubber. The buttressing pledget can be made radiopaque by the addition of a suitable material, such as barium sulfate. The pledget can be combined with a surgical suture or ligature.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
103 words
An article of manufacture comprising a buttressing pledger having essentially a rectangular parallelpiped form and two openings, the two openings being essentially parallel to each other and each of said two openings having a proximal end on a first side and a distal end on a second side of the rectangular parallelpiped form, each of said two openings being continuous from the proximal to the distal end, and a raised surface adjacent to at least each of the proximal ends, and in combination with a wound closure device, the buttressing pledger manufactured from a nonporous, synthetic elastomer in combination with a radiopaque material.
Claim 2
Dependent Claim
