Abstract

Tissue adjustment implants useful for adjusting a position of tissue in a patient are described. In an embodiment, a tissue adjustment implant includes a main body having a series of outwardly-extending projections. The tissue adjustment implants can be used in a variety of treatments, such as in the treatment of Obstructive Sleep Apnea and snoring.

Claims

1. A tissue adjustment implant comprising:

a main body extending along a lengthwise axis and having first and second opposing ends, a longitudinal midpoint, first and second opposing sides, first and second opposing surfaces, and a first width extending from the first side to the second side orthogonally to the longitudinal axis and through the longitudinal midpoint;

a first anchor portion disposed on the first end, the first anchor portion having a second width extending orthogonally to the longitudinal axis, the second width being greater than the first width; and

a series of projections disposed on the first side, each projection of the series of projections extending away from the second end and the longitudinal axis of the main body;

further comprising a throat portion that extends from the main body to the first anchor portion and transitions from the first width to the second width.

2. The tissue adjustment implant of claim 1, wherein the second side contains no projections.

3. The tissue adjustment implant of claim 1, wherein the first anchor portion defines an arrowhead having a first arrowhead side oriented at an angle to a second arrowhead side.

4. The tissue adjustment implant of claim 3, wherein the angle is an acute angle.

5. The tissue adjustment implant of claim 4, wherein the acute angle comprises an angle between about 35 degrees and about 90 degrees.

6. The tissue adjustment implant of claim 4, wherein the acute angle comprises an angle of about 45 degrees.

7. The tissue adjustment implant of claim 4, wherein the acute angle comprises an angle of 45 degrees.

8. The tissue adjustment implant of claim 3, wherein the angle is an obtuse angle.

9. The tissue adjustment implant of claim 3, wherein the angle is a right angle.

10. The tissue adjustment implant of claim 3, wherein the arrowhead defines a terminal point;

and

wherein the terminal point comprises a rounded point.

11. The tissue adjustment implant of claim 1, wherein at least one projection of the series of projections comprises a wing-shaped member having a base and an end, the base having a base width that extends parallel to the longitudinal axis of the main body and the end having an end width that extends parallel to the longitudinal axis of the main body;

and

wherein the base width is greater than the end width.

12. The tissue adjustment implant of claim 1, wherein each projection of the series of projections comprises a wing-shaped member having a base and an end, the base having a base width that extends parallel to the longitudinal axis of the main body and the end having an end width that extends parallel to the longitudinal axis of the main body and that is less than the base width.

13. The tissue adjustment implant of claim 1, wherein said tissue adjustment implant comprises a bioremodelable material.

14. The tissue adjustment implant of claim 13, wherein the bioremodelable material comprises an extracellular matrix (ECM) material.

15. The tissue adjustment implant of claim 14, wherein the extracellular matrix material comprises small intestine submucosa (SIS).

16. The tissue adjustment implant of claim 1, wherein said tissue adjustment implant comprises an integral, multi-laminate construct comprising layers of small intestine submucosa (SIS).

17. The tissue adjustment implant of claim 1, wherein the throat portion is only on the first side.

18. The tissue adjustment implant of claim 17, wherein the second side contains no projections.

19. The tissue adjustment implant of claim 1, wherein the main body, the first anchor portion, the series of projections, and the throat portion is formed as an integral unit.

20. A tissue adjustment implant comprising:

a main body extending along a lengthwise axis and having first and second opposing ends, a longitudinal midpoint, first and second opposing sides, first and second opposing surfaces, and a first width extending from the first side to the second side orthogonally to the longitudinal axis and through the longitudinal midpoint;

a first anchor portion disposed on the first end, the first anchor portion defining an arrowhead having a first arrowhead side oriented at an acute angle to a second arrowhead side and having a second width extending orthogonally to the longitudinal axis;

a throat portion that extends from the main body to the first anchor portion and transitions from the first width to the second width; and

a series of projections disposed only on the first side, each projection of the series of projections extending away from the second end and the longitudinal axis of the main body and comprising a wing-shaped member having a base and an end, the base having a base width that extends parallel to the longitudinal axis of the main body and the end having an end width that extends parallel to the longitudinal axis of the main body and that is less than the base width.
