Devices for enclosing, manipulating, debulking and removing tissue through minimal incisions
First Claim
1. A device usable, in combination with a standard forcep/grasper instrument, to deploy a surgical containment sac within a body cavity and to subsequently retrieve said containment sac from said body cavity, said device comprising:
- a tubular introducer sheath having a distal end, a proximal end, and a hollow lumen extending longitudinal therethrough;
a flexible containment sac comprising;
(a) a flexible sac body having at least one opening thereinto; and
(b) a rigid grasping member connected to said sac body, said grasping member being sized and configured to be graspable by said standard forcep/grasper instrument;
said containment sac and said tubular introducer sheath being sized and configured relative to one another so as to permit said containment sac to be alternately deployable in;
(a) a first "pre-operative" position wherein said containment sac body is fully disposed within a lumen of said introducer sheath with said grasping member extending at least partially out of the proximal end of said introducer sheath;
(b) a second "deployed" position whereby said containment sac is expelled out of the distal end of said introducer sheath; and
(c) a third "retraction" position whereby a portion of said containment sac is withdrawn into the lumen of the introducer sheath, while a portion of said containment sac remains disposed beyond the distal end of said introducer sheath.

Abstract
Containment sacs insertable into a body cavity through a minimal access incision for purposes of containing, manipulating, treating and/or extracting material from the body cavity. The sac may comprise a flexible sac body having at least one opening thereinto and a resilient or spring loaded rim member disposed about the opening to urge the opening to an open configuration when deployed in the body cavity. The containment sac may be further utilized in combination with a dedicated introducer sheath through which the containment sac may be inserted and extracted. A valving member may be positioned on the introducer sheath to prevent escape of gas from a pressurized body cavity such as a pneumoperitoneal. The containment sac may incorporate a grasping member whereby the containment sac may be grasped and inserted using a standard forecep/grasper instrument. Alternatively, the containment sac may be attached to an elongate rod member usable to insert and extract the containment sac. Additionally disclosed is an expandable embodiment of the containment sac which may be selectively expanded through the use of a separate expansion instrument or balloon.

40. A surgical containment sac insertable into a body cavity through a minimal access incision, said containment sac comprising:
-
(a) a flexible sac body having at least one opening thereinto; (b) a rigid grasping member connected to said sac body, said grasping member being sized and configured to be graspable by a standard forcep/grasper instrument; (c) said containment sac being sized and configured so as to be collapsible to a configuration which will pass through a minimal access incision of approximately one centimeter in length. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59)
