Abstract
Abstract A visceral anchor and method for visceral wall mobilization is disclosed. The visceral anchor includes an elongated cross bar to which a suture is attached at a location substantially in the center of the cross bar. The cross bar further includes a helical spring sheath which jackets a rigid rod, the sheath extending beyond the ends of the rod to form flexible ends. An alternative embodiment includes a second suture attached to one of the ends of the cross bar. The sutures are used for orienting the anchor during insertion into and removal from a hollow viscus. The method of visceral wall mobilization includes providing a tract through the skin into a hollow intra-abdominal viscus and inserting the anchor into the viscus lumen. The sutures extend through the tract and the unattached ends remain on the outside of the body. The center suture is pulled to orient the anchor for mobilization of the visceral wall. The end suture is pulled to orient the anchor for removal.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
97 words
A visceral anchor comprising: a biocompatible elongated cross bar having opposite ends; a first flexible biocompatible suture having a first attached end and a second unattached end, the first attached end being attached to said cross bar at a location substantially in the center of said cross bar; and the opposite ends of said cross bar being flexible, and there being interposed between said flexible opposite ends a relatively rigid center portion, the first attached end being attached to the center portion, whereby said flexible opposite ends are adapted for atraumatic engagement with body tissue being anchored.
Claim 2
Dependent Claim
97 words
A visceral anchor comprising: a biocompatible elongated cross bar having opposite ends; a first flexible biocompatible suture having a first attached end and a second unattached end, the first attached end being attached to said cross bar at a location substantially in the center of said cross bar; and the opposite ends of said cross bar being flexible, and there being interposed between said flexible opposite ends a relatively rigid center portion, the first attached end being attached to the center portion, whereby said flexible opposite ends are adapted for atraumatic engagement with body tissue being anchored.
Claim 3
Dependent Claim
128 words
A visceral anchor comprising: a biocompatible elongated cross bar having opposite ends; a first flexible biocompatible suture having a first attached end and a second unattached end, the first attached end being attached to said cross bar at a location substantially in the center of said cross bar; the opposite ends of said cross bar being flexible, and there being interposed between said flexible opposite, ends a relatively rigid center portion, the first attached end being attached to the center portion, whereby said flexible opposite ends are adapted for atraumatic engagement with body tissue being anchored; and a second flexible biocompatible suture having a third attached end and a fourth unattached end, the third attached end being attached to one of said opposite ends of said cross bar.
Claim 4
Dependent Claim
128 words
A visceral anchor comprising: a biocompatible elongated cross bar having opposite ends; a first flexible biocompatible suture having a first attached end and a second unattached end, the first attached end being attached to said cross bar at a location substantially in the center of said cross bar; the opposite ends of said cross bar being flexible, and there being interposed between said flexible opposite, ends a relatively rigid center portion, the first attached end being attached to the center portion, whereby said flexible opposite ends are adapted for atraumatic engagement with body tissue being anchored; and a second flexible biocompatible suture having a third attached end and a fourth unattached end, the third attached end being attached to one of said opposite ends of said cross bar.
Claim 5
Dependent Claim
145 words
A visceral anchor comprising: a biocompatible elongated cross bar having opposite ends; a first flexible biocompatible suture having a first attached end and a second unattached end, the first attached end being attached to said cross bar at a location substantially in the center of said cross bar; the opposite ends of said cross bar being flexible, there being interposed between the flexible ends a rigid center portion, the first attached end being attached to the center portion; a second flexible biocompatible suture having a third attached end and a fourth unattached end, the third attached end being attached to one of the opposite ends of said cross bar; and said cross bar comprises a biocompatible rigid rod and a biocompatible helical spring sheath, the rod being jacketed by the sheath, the sheath extending beyond both ends of the rod to form said flexible ends.
Claim 6
Dependent Claim
145 words
A visceral anchor comprising: a biocompatible elongated cross bar having opposite ends; a first flexible biocompatible suture having a first attached end and a second unattached end, the first attached end being attached to said cross bar at a location substantially in the center of said cross bar; the opposite ends of said cross bar being flexible, there being interposed between the flexible ends a rigid center portion, the first attached end being attached to the center portion; a second flexible biocompatible suture having a third attached end and a fourth unattached end, the third attached end being attached to one of the opposite ends of said cross bar; and said cross bar comprises a biocompatible rigid rod and a biocompatible helical spring sheath, the rod being jacketed by the sheath, the sheath extending beyond both ends of the rod to form said flexible ends.
Claim 7
Dependent Claim
29 words
The visceral anchor of claim 3 in which: the cross bar opposite ends include epoxy material at their outermost points, the epoxy being bonded to the helical spring sheath.
Claim 8
Dependent Claim
32 words
The visceral anchor of claim 4 in which: said first suture and said second suture are of unitary construction, the first attached end and third attached end being connected beneath the sheath.
