ABSTRACT:
Opposable surgical clamp members having opposable resilient pads with wedge-shaped and cylindrical protrusions extending from the surfaces of the pads and the use of such members for occluding vessels and other tubular body structures are described. The protrusions are arranged such that when the members are moved toward one another, the protrusions of one pad interdigitate with the protrusions of the other pad. Upon engagement with a vessel, portions of the vessel are forced into the interdigital spaces providing for improved gripping of the vessel. The protrusions also resist lateral or transverse movement of a clamped vessel relative to the pads. The existence of through holes under the pad surface alters the relative resiliency of the pad, allowing for an overall pad resiliency that minimizes trauma to a clamped vessel while allowing the local resiliency of the protrusions themselves to be of a hardness to avoid excessive deflection and retain the desired shape and gripping ability.
