Abstract

An active bodily ring having a housing adapted to be sutured to a bodily component and a loop disposed in the housing, the loop capable of actively expanding and compressing during the bodily components normal function. The housing defines a first chamber and a second chamber, the first chamber containing the loop and the second chamber providing a region capable of being sutured to the bodily component. In one embodiment, the housing can be a crimped-fabric housing. In another embodiment, the housing can be a woven-fabric housing having elastic properties. The housing can be made from polyester.

Claims

1. An active bodily ring, comprising:

a housing adapted to be sutured to a bodily component; and

a loop disposed in the housing, said loop capable of actively expanding and compressing during the bodily components normal function.

2. The active bodily ring of claim 1, wherein the housing defines a first chamber and a second chamber, the first chamber containing the loop and the second chamber providing a region capable of being sutured to the bodily component.

3. The active bodily ring of claim 1, wherein the housing is a crimped-fabric housing.

4. The active bodily ring of claim 1, wherein the housing is a woven-fabric housing having elastic properties.

5. The active bodily ring of claim 1, wherein the housing includes polyester.

6. The active bodily ring of claim 1, wherein the loop is an open-ended flat coil loop, each end adapted to substantially allow free movement of the loop within the housing.

8. The active bodily ring of claim 1, wherein the loop provides a retraction force between 3 and 4 Newtons when maximally stretched.

9. The active bodily ring of claim 1, wherein the loop is made from a material selected from a group consisting of a metal, a metal alloy, and a polymer resin.

10. The active bodily ring of claim 1, wherein the loop is a distensible coiled spring including a plurality loops.

11. The active bodily ring of claim 1, wherein a bodily component is selected from a group consisting of a heart, a larynx, an esophagus, a trachea, a pharynx, an eyelid, a nostril, a mouth, an anus, a rectocele, a pupil, a rectum, a bladder, and a vagina.

12. The active bodily ring of claim 11, wherein the ring is sutured to a mitral value annulus of the heart.

13. The active bodily ring of claim 12, wherein the ring is used for a medical treatment selected from the group comprising ischemic mitral valve regurgitation, prolapse mitral valve regurgitation, mitral valve regurgitation associated with left ventricular aneurysms, mitral valve regurgitation associated dilated cardiomyopathy, and Barlow'"'"'s disease.

7. The active bodily ring of claim 7, wherein one end of the loop includes a plurality of protrusions and the other end of the loop includes a plurality of notches for engaging the protrusions, thereby allowing the loop to be adjusted.

14. A method of repairing a sphincter-type bodily component, comprising:

disposing a loop in a housing, said loop capable of actively expanding and compressing during the bodily components normal function; and

suturing the housing to the bodily component.

15. The method of claim 14, wherein the housing defines a first chamber and a second chamber, the first chamber containing the loop and the second chamber providing a region capable of being sutured to the bodily component.

16. The method of claim 14, wherein the loop is an open-ended flat coil loop, each end adapted to substantially allow free movement of the loop within the housing.

17. The method claim 14, wherein a bodily component is selected from a group consisting of a heart, a larynx, an esophagus, a trachea, a pharynx, an eyelid, a nostril, a mouth, an anus, a rectocele, a pupil, a rectum, a bladder, and a vagina.

18. The method of claim 17, wherein the ring is sutured to a mitral value annulus of the heart.

19. The method of claim 18, wherein the ring is used for a treatment selected from a group consisting of ischemic mitral valve regurgitation, prolapse mitral valve regurgitation, mitral valve regurgitation associated with left ventricular aneurysms, mitral valve regurgitation associated dilated cardiomyopathy, and Barlow'"'"'s disease.

20. An active bodily ring, comprising:

means for adapting a housing to be sutured to a bodily component; and

means for allowing substantially free movement a loop disposed in the housing, the loop capable of actively expanding and compressing during the bodily components normal function.
