    摘要: A balloon dissection apparatus for forming an anatomic working space alongside an elongate vessel in a body having a tunneling shaft having proximal and distal extremities. A flexible elongate substantially cylindrical balloon is carried by the tunneling shaft and has proximal and distal extremities. The balloon has at least a portion of the distal extremity folded inwardly into the balloon to shorten the length of the balloon so that the folded balloon has a length which is not substantially greater than the length of the tunneling shaft. An inflation tube is coupled to the balloon for inflating the balloon to cause the distal folded extremity to evert and roll outwardly to provide an inflated balloon having a length greater than the length of the tunneling shaft.

    摘要: 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.

    摘要: Replaceable pads are provided for jaw-type surgical clamps, clips and other occluding devices. The pads include elastomer impregated mesh embedded in and extending from an elastomeric cushion. When engaged with a vessel, the mesh partially penetrates the adventitial layers of the vessel, securing outer adventitial layers against inner vessel layers to resist relative movement of the layers, thereby minimizing slippage of the device along the clamped vessel. The embedded mesh also functions to stabilize the cushion, especially against lateral movement.
