Laparoscopy organ retrieval apparatus and procedure
First Claim
1. In a minimum invasion surgical apparatus of the type used to perform laparoscopic organ removal from a body cavity utilizing a keyhole incision which is substantially smaller than the organ, the organ being dissected from the body and isolated within the body cavity, removal of the organ from the body cavity being achieved through use of a laparoscopic port, a prepackaged compacted entrapment envelope and a moresellator means after the organ is placed in the entrapment envelope and removed by morsellation, the improvement comprising:
- a sheath for insertion through the laparoscopic port into the body cavity, the sheath containing said prepackaged, compacted entrapment envelope; and
said entrapment envelope constructed of flexible fluid impermeable materials having an opening and closing means extending through the port and sheath to an exterior position relative to the body cavity.

Abstract
Laparoscopy organ retrieval apparatus and procedures are presented for minimum invasion surgery inclusive of laparoscopic nephrectomy, cholecystectomy and other organ dissection, morsellation removal from the abdomen through a keyhole incision. The apparatus and procedures permit the safe and total removal of an organ from a body cavity in a morsellated condition through the combination utilization of an entrapment envelope sheath. The entrapment envelope having an apparatus for opening and closing, the apparatus controlled from an exterior position of the body cavity wherein the entrapment envelope after entry of the sheath is extruded from the sheath which has been inserted through a laparoscopic port in place in a keyhole surgical opening. The entrapment envelope is constructed of flexible, relatively low bulk fluid impermeable materials having sufficient strength to contain morsellator entry, organ fragmentation and removal.

12. A minimum invasion surgical procedure for laparoscopic organ removal from a body cavity through a keyhole body incision, comprising:
-
surgically opening said keyhole body incision in the abdomen; inflating the body cavity with CO2 ; inserting a laparoscopic port into the keyhole incision and utilizing said keyhole incision for surgically severing an organ from the body and holding such organ in the body cavity; inserting a sheath containing a prepackaged, compacted entrapment envelope constructed of flexible fluid impermeable materials having an opening and closing means extending through the laparoscopic port and sheath to an exterior portion relative to the body cavity through the laparoscopic port and extruding the envelope without risk of handling damage or risk of handling contamination, into the body cavity beyond the end of the laparoscopic port opening through means exterior of the body cavity; opening the entrapment envelope utilizing said opening means; inserting the severed organ into the entrapment envelope; closing the entrapment envelope utilizing said closing means; withdrawing the sheath; withdrawing the laparoscopic port; withdrawing the open portion of the entrapment envelope to an exterior position of the body cavity; introducing morsellizing means into the open end of the entrapment envelope; morsellizing and removing the severed organ from the envelope; and removing the entrapment envelope and remaining tissue from the body cavity through the keyhole incision. - View Dependent Claims (13, 14, 15, 16, 17)

18. In a minimum invasion surgical apparatus of the type used to perform laparoscopic organ removal from a body cavity utilizing a keyhole incision which is substantially smaller than the organ, the organ being dissected from the body and isolated within the body cavity, removal of the organ from the body cavity being achieved through use of a laparoscopic port, an entrapment envelope and a morsellator means after the organ is placed in the entrapment envelope and removed by morsellation, the improvement comprising:
-
a sheath for insertion through the laparoscopic port into the body cavity, the sheath containing a prepackaged, compacted entrapment envelope; said entrapment envelope being constructed of flexible fluid impermeable materials having an opening and closing means communicating through the port and sheath to an exterior position relative to the body cavity; and the sheath is provided with a cap on a first end which is exterior of the body cavity during insertion of the entrapment envelope through a second end which accommodates the opening/closing means, the cap provides a pressure seal to the sheath, the sheath outer diameter sufficiently similar to the inside diameter of the laparoscopic port to avoid significant body cavity gas pressure loss.
