Abstract
Surgical clamps, tissue retractors and surgical stabilizers are disclosed having gripping surfaces from which extend resilient filaments. The distal ends of some of the resilient filaments abut against engaged vessels, tissues or organs to restrict movement of the vessels, tissue or organs relative to the gripping surfaces. In the preferred embodiment, the resilient filaments are arranged in rows and oriented at particular angles relative to the gripping surfaces. Methods of applying resilient filaments to pads for attachment to a surgical clamp, tissue retractor or surgical stabilizer are also disclosed.
