Abstract
Abstract A tissue manipulator (50) is provided which is insertable through an endoscopic tube to enable a surgeon to manipulate tissue inside a body cavity. The tissue manipulator includes an expandable frame (70) comprising a plurality of flexible, interconnected frame members (72-76) which are adapted to expand laterally outward into a spatula-like platform for engaging the tissue. The platform is selectively expandable into a tulip-shaped configuration and a bulb-shaped configuration to manipulate large body organs such as the liver, lungs or intestines without risk of injury to such organs. The platform is infinitely adjustable in size from its collapsed configuration to its expanded configuration.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
39 words
An endoscopic tissue manipulator, comprising: a handle; a support shaft extending from said handle; an expandable frame mounted at the distal end of said support shaft; and means for expanding said frame into a suitable configuration for manipulating tissue.
Claim 2
Dependent Claim
30 words
The tissue manipulator of Claim 1, wherein: said frame comprises a plurality of frame members which are adapted to expand laterally outward into a spatula-like platform for engaging the tissue.
Claim 3
Dependent Claim
24 words
The tissue manipulator of Claim 2, wherein: said frame members are adapted to expand bilaterally outward to form a platform of generally planar configuration.
Claim 4
Dependent Claim
21 words
The tissue manipulator of Claim 2, wherein: said frame members are selectively expandable into a tulip-shaped configuration and a bulb-shaped configuration.
Claim 5
Dependent Claim
19 words
The tissue manipulator of Claim 2, which includes: means for retaining said frame members in an outwardly expanded configuration.
Claim 6
Dependent Claim
69 words
An endoscopic tissue manipulator, comprising: a handle; a support shaft extending from said handle; a tube slidably mounted on said support shaft for longitudinal movement relative to said support shaft; and an expandable frame mounted at the distal end of said support shaft and connected to said tube, said frame being expandable by movement of said tube relative to said support shaft to provide a platform for manipulating tissue.
Claim 7
Dependent Claim
32 words
The tissue manipulator of Claim 6, wherein: said frame comprises a plurality of flexible, interconnected frame members which are adapted to expand laterally outward into a spatula-like platform for engaging the tissue.
Claim 8
Dependent Claim
21 words
The tissue manipulator of Claim 7, wherein: said frame members are selectively expandable into a tulip-shaped configuration and a bulb-shaped configuration.
Claim 9
Dependent Claim
19 words
The tissue manipulator of Claim 7, which includes: means for retaining said frame members in an outwardly expanded configuration.
Claim 10
Dependent Claim
103 words
An endoscopic tissue manipulator for insertion into an endoscopic tube for manipulating tissue in a body cavity, comprising: a handle; a support shaft extending from said handle; an actuator tube slidably mounted on said support shaft for longitudinal movement relative to said support shaft; and a tissue manipulating frame mounted at the distal end of said support shaft and connected to said actuator tube, said frame having a collapsed configuration for insertion through the endoscopic tube, and said frame being expandable by movement of said actuator tube relative to said shaft to provide a platform for manipulating the tissue in the body cavity.
