Abstract
Abstract A constriction device that constricts body tissue includes fixation structures for fixing the device on constricted body tissue. The device includes an elongated sleeve including an inner surface and opposed opened ends. The device is formed from expandable or elastic material so that when in an expanded condition, body tissue to be constricted may be received therein and thereafter, when released from the expanded condition, the body tissue is constricted by the device. The fixation structures include a plurality of fixation elements on the inner surface of the sleeve that grasp the body tissue upon release of the sleeve from the expanded condition to fix the device on the constricted tissue.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
84 words
1 . A constriction device that constricts body tissue, the device comprising: an elongated sleeve, the sleeve including an inner surface and opposed opened ends and being formed from expandable material to receive therein, when in an expanded condition, body tissue to be constricted and to constrict the body tissue therein when released from the expanded condition; and a plurality of fixation elements on the inner surface of the sleeve that grasp the body tissue upon release of the sleeve from the expanded condition.
Claim 2
Dependent Claim
84 words
1 . A constriction device that constricts body tissue, the device comprising: an elongated sleeve, the sleeve including an inner surface and opposed opened ends and being formed from expandable material to receive therein, when in an expanded condition, body tissue to be constricted and to constrict the body tissue therein when released from the expanded condition; and a plurality of fixation elements on the inner surface of the sleeve that grasp the body tissue upon release of the sleeve from the expanded condition.
Claim 3
Dependent Claim
15 words
2 . The device of claim 1 wherein the fixation elements include radio opaque material.
Claim 4
Dependent Claim
20 words
3 . The device of claim 1 wherein the fixation elements are formed of material visible under X ray fluoroscopy.
Claim 5
Dependent Claim
19 words
4 . The device of claim 1 wherein the fixation elements are adjacent to one of the opposed openings.
Claim 6
Dependent Claim
35 words
5 . The device of claim 1 wherein the fixation elements are arranged in a side-by-side relation to grasp the body tissue between adjacent fixation elements when the sleeve is released from the expanded condition.
Claim 7
Dependent Claim
13 words
6 . The device of claim 1 wherein the fixation elements include barbs.
Claim 8
Dependent Claim
34 words
7 . The device of claim 1 wherein the sleeve further includes a longitudinal side wall extending between the opposed opened ends and wherein the fixation elements are integral to the longitudinal side wall.
Claim 9
Dependent Claim
20 words
8 . The device of claim 1 wherein the fixation elements are adhered to the inner surface of the sleeve.
Claim 10
Dependent Claim
31 words
9 . The device of claim 1 wherein the fixation elements include inner surfaces that engage the body tissue and wherein the inner surfaces of the fixation elements are roughened surfaces.
Claim 11
Dependent Claim
37 words
10 . The device of claim 1 wherein the sleeve has a longitudinal dimension between the opposed opened ends and wherein each of the fixation elements has a major dimension along the longitudinal dimension of the sleeve.
Claim 12
Dependent Claim
19 words
11 . The device of claim 10 wherein the fixation elements are adjacent to one of the opposed openings.
Claim 13
Dependent Claim
37 words
12 . The device of claim 1 further including a circumferential compression band on the inner surface of the sleeve, the compression band being in between one of the opened ends and the plurality of fixation elements.
Claim 14
Dependent Claim
23 words
13 . The device of claim 12 wherein the fixation elements are arranged in plural rows circumscribing the inner surface of the sleeve.
Claim 15
Dependent Claim
67 words
14 . A constriction device for constricting body tissue, the device comprising: sleeve means including opposed opened ends and being formed from expandable material for receiving therein, when in an expanded condition, body tissue to be constricted and for constricting the body tissue therein when released from the expanded condition; and fixation means for grasping the body tissue upon release of the sleeve from the expanded condition.
Claim 16
Dependent Claim
67 words
14 . A constriction device for constricting body tissue, the device comprising: sleeve means including opposed opened ends and being formed from expandable material for receiving therein, when in an expanded condition, body tissue to be constricted and for constricting the body tissue therein when released from the expanded condition; and fixation means for grasping the body tissue upon release of the sleeve from the expanded condition.
Claim 17
Dependent Claim
17 words
15 . The device of claim 14 wherein the fixation means comprises a plurality of fixation elements.
Claim 18
Dependent Claim
35 words
16 . The device of claim 15 wherein the fixation means further includes a compression band circumscribing the sleeve means and being in between one of the opposed ends and the plurality of fixation elements.
