Abstract: 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 CO2 insufflation, when the primary means of hemostasis or pneumatic CO2 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 CO2 insufflation, without exchanging the introducer sheath or laparoscopic port.
