According to the present invention, improved methods and apparatus are provided for regaining hemostasis or otherwise minimizing leakage during endoluminal, surgical or percutaneous intraluminal procedures, and for providing a seal during laparoscopic surgical procedures where there is leakage of the CO insufflation, when the primary means of hemostasis or pneumatic CO seal is compromised or fails. More particularly the present invention relates to devices having a front hub and a rear hub, one or other of which is adapted to retain a compression seal such that when the front and rear hub are matingly engaged, axial and radial pressure is applied to the compression plug and any devices located therebetween, thereby achieving a seal. The compression device can be applied while a guidewire or additional devices remain within the leaking sheath or trocar, thereby allowing the physician to maintain hemostasis or adequate CO insufflation, without exchanging the introducer sheath or laparoscopic port.

Method and device for maintaining a seal

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.

Vascular clamps and surgical retractors with directional filaments for tissue engagement

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.
