Abstract

Abstract A constriction device that constricts body tissue and is formed of relatively thin elastic material includes a tear resistance structure to preclude an inadvertent tear in the device from propagating through the device. The tear resistance structure includes a plurality of intersecting ribs formed in the elastic material. The ribs circumscribe the device and define rectangular, square, diamond, wavy, or knurled patterns.

Claims Analysis

Total Claims: 25
Claim 1
Independent Claim 84 words
A device that engages internal body tissue, the device comprising: an implantable elongated sleeve having a generally uniform thickness and including at least one opened end and being formed from elastic material to receive the internal body tissue to be engaged when in an expanded condition, and to engage the internal body tissue when released from the expanded condition; and a tear resistance structure being an increased thickness of at least one portion of the elastic material that resists tear propagation in the sleeve.
Claim 2
Independent Claim 84 words
A device that engages internal body tissue, the device comprising: an implantable elongated sleeve having a generally uniform thickness and including at least one opened end and being formed from elastic material to receive the internal body tissue to be engaged when in an expanded condition, and to engage the internal body tissue when released from the expanded condition; and a tear resistance structure being an increased thickness of at least one portion of the elastic material that resists tear propagation in the sleeve.
Claim 3
Dependent Claim 18 words
The device of claim 1 wherein the tear resistance structure includes a plurality of ribs in the sleeve.
Claim 4
Dependent Claim 34 words
The device of claim 2 wherein the plurality of ribs include a first plurality of ribs and a second plurality of ribs and wherein the first and second pluralities of ribs intersect each other.
Claim 5
Dependent Claim 22 words
The device of claim 3 wherein the first and second pluralities of ribs intersect each other to form a pattern of squares.
Claim 6
Dependent Claim 22 words
The device of claim 3 wherein the first and second pluralities of ribs intersect each other to form a pattern of diamonds.
Claim 7
Dependent Claim 20 words
The device of claim 3 wherein one of the first and second pluralities of ribs forms a pattern of waves.
Claim 8
Dependent Claim 15 words
The device of claim 6 wherein the pattern of waves is circumferential about the sleeve.
Claim 9
Dependent Claim 14 words
The device of claim 2 wherein the plurality of ribs forms a knurl pattern.
Claim 10
Dependent Claim 18 words
The device of claim 1 wherein the tear resistance structure is on an inner surface of the sleeve.
Claim 11
Independent Claim 36 words
A device that engages internal body tissue, the device comprising: sleeve means formed of implantable elastic material for compressively engaging internal body tissue received therein; and means for tear propagation resistance formed in the elastic material.
Claim 12
Independent Claim 36 words
A device that engages internal body tissue, the device comprising: sleeve means formed of implantable elastic material for compressively engaging internal body tissue received therein; and means for tear propagation resistance formed in the elastic material.
Claim 13
Dependent Claim 18 words
The device of claim 10 wherein the tear resistance means is an increased thickness of the elastic material.
Claim 14
Dependent Claim 19 words
The device of claim 10 wherein the tear resistance means includes a plurality of ribs in the elastic material.
Claim 15
Dependent Claim 34 words
The device of claim 12 wherein the plurality of ribs include a first plurality of ribs and a second plurality of ribs and wherein the first and second pluralities of ribs intersect each other.
Claim 16
Dependent Claim 22 words
The device of claim 13 wherein the first and second pluralities of ribs intersect each other to form a pattern of squares.
Claim 17
Dependent Claim 22 words
The device of claim 13 wherein the first and second pluralities of ribs intersect each other to form a pattern of diamonds.
Claim 18
Dependent Claim 20 words
The device of claim 13 wherein one of the first and second pluralities of ribs forms a pattern of waves.
Claim 19
Dependent Claim 15 words
The device of claim 16 wherein the pattern of waves is circumferential about the sleeve.
Claim 20
Dependent Claim 14 words
The device of claim 12 wherein the plurality of ribs forms a knurl pattern.
Claim 21
Dependent Claim 18 words
The device of claim 10 wherein the tear resistance means is on an inner surface of the sleeve.
Claim 22
Independent Claim 76 words
A device that engages internal body tissue, the device comprising: an implantable elongated sleeve including at least one opened end and being formed from elastic material to receive the internal body tissue to be compressively engaged when in an expanded condition, and to compressively engage the internal body tissue when released from the expanded condition, the elastic material of the elongated sleeve including a tear resistance structure that resists propagation of a tear in the sleeve.
Claim 23
Independent Claim 76 words
A device that engages internal body tissue, the device comprising: an implantable elongated sleeve including at least one opened end and being formed from elastic material to receive the internal body tissue to be compressively engaged when in an expanded condition, and to compressively engage the internal body tissue when released from the expanded condition, the elastic material of the elongated sleeve including a tear resistance structure that resists propagation of a tear in the sleeve.
Claim 24
Independent Claim 44 words
A device that compressively engages internal body tissue, the device comprising: sleeve means formed of implantable elastic material for elastically compressing internal body tissue received therein, the elastic material of the sleeve means including a means for resisting tear propagation in the sleeve means.
Claim 25
Independent Claim 44 words
A device that compressively engages internal body tissue, the device comprising: sleeve means formed of implantable elastic material for elastically compressing internal body tissue received therein, the elastic material of the sleeve means including a means for resisting tear propagation in the sleeve means.
