Abstract

The present invention relates to a tissue repair device for use in surgical methods. The tissue repair device comprises a filiform having a longitudinal axis and a transverse width, wherein a force of at least 30 N can be exerted along the longitudinal axis of the device without distortion of the device and at least part of said filiform comprises interstices on a surface of the filiform, the interstices having a cross-sectional width in the range of 50 micrometers to 200 micrometers. In surgical methods, features of the device can provide for lubricious movement of the device within surrounding tissue for up to 72 hours, providing for adjustment of the device and positioning of the device in the body after its initial placement. Subsequently, traction of the device to the surrounding tissue can be achieved as the features of the device cause the device to act as a scaffold for tissue ingrowth into and around the structure of the device.

Claims

1. A tissue repair device comprising a filiform having a longitudinal axis and a transverse width, wherein a force of at least 30 N can be exerted along the longitudinal axis of the device without distortion of the device and at least part of said filiform comprises interstices on a surface of the filiform, the interstices having a cross-sectional width in the range of 50 micrometers to 200 micrometers.

2. The tissue repair device of claim 1, comprising at least one filament wherein said filament is arranged to provide interstices of cross-sectional width in the range 50 micrometers to 200 micrometers.

3. The tissue repair device of claim 2, comprising at least two filaments intertwined together to form a filiform with interstices in the range 50 micrometers to 200 micrometers.

4. The tissue repair device of claim 3, wherein two filaments are arranged to provide strands with interstices in the range 50 micrometers to 200 micrometers between the filaments and the strands of intertwined filaments are further intertwined together such that multiple strands are joined together to form the filiform wherein the spaces between the strands are in the range of 50 micrometers to 200 micrometers.

5. The tissue repair device of claim 1, wherein said filiform is of width in the range 2 mm to 11 mm and of thickness in the range 10 micrometers to 50 micrometers.

22. An implant comprising the tissue repair device of claim 1 and a support portion.

23. The implant of claim 22, wherein pairs of the tissue repair device are conjoined to the support portion.

24. The implant of claim 23 wherein the support portion is a tape or a mesh.

25. The implant of claim 24, wherein the support portion is a mesh and the mesh comprises spaces between the strands of around 1 to 10 mm.

6-21. -21. (canceled)

26-32. -32. (canceled)

33. A method of supporting a defined tissue structure in the body comprising the steps of:

(a) providing at least a first tissue repair device comprising a filiform having a longitudinal axis and a transverse width wherein at least part of said filiform comprises interstices on a surface of the filiform wherein said interstices have a cross-sectional width in the range of 50 micrometers to 200 micrometers and a force of at least 30 N can be exerted along the longitudinal axis of the device without distortion of the device;

(b) fixing a first end of the first device to a first fixing point on a first side of the defined tissue structure to be supported;

(c) fixing a second end of the first device to a second fixing point on a second side of the defined tissue structure to be supported; and

(d) positioning the first device under the defined tissue structure to be supported.

38. The method of claim 33, further comprising the steps of:

(a) providing a second tissue repair device comprising a filiform having a longitudinal axis and transverse width wherein at least part of said filiform comprises interstices on a surface of the filiform wherein said interstices have a cross-sectional width in the range of 50 micrometres to 200 micrometres and a force of at least 30 N can be exerted along the longitudinal axis of the device without distortion of the device, and a support portion interposed between said first tissue repair device and said second tissue repair device, wherein said support portion is conjoined to one end of the first device and one end of the second device;

(b) inserting a first end of the first tissue repair device through an incision in a body, past a first lateral side of a defined structure to be supported such that that at least part of the first tissue repair device exits the body;

(c) inserting a first end of the second tissue repair device through an incision in the body, past a second lateral side of the defined structure to be supported such that at least part of a second tissue repair device exits the body; and

(d) positioning the support portion interposed between the first and second tissue repair devices adjacent to the defined tissue to be supported such that the support portion provides support to the defined tissue.

39. The method of claim 38, wherein the incision in the body is a vaginal incision, and the defined structure to be supported is a urethra.

41. The method of claim 38, further comprising the step of adjusting the position of the support portion under the defined tissue structure to be supported.

42. The method of claim 41 wherein the step of adjusting the position of the support portion under the defined structure to be supported is performed within 72 hours of inserting the device in the body.

46. The method of claim 39, wherein the first end of the tissue repair device is further inserted through a first obturator foramen.

40. (canceled)

43. A method for supporting prolapse in at least one of vagina and uterus, comprising the steps of:

(a) providing at least a first pair and a second pair of tissue repair devices each device comprising a filiform having a longitudinal axis and transverse width wherein at least part of said filiform comprises interstices on a surface of the filiform wherein said interstices have a cross-sectional width in the range of 50 micrometers to 200 micrometers and a force of at least 30 N can be exerted along the longitudinal axis of the device without distortion of the device and a support portion interposed between said first and second pairs of devices, wherein said support portion is conjoined to one end of each of the first and second pairs of devices;

(b) inserting a first end of a first pair of tissue repair devices through a vaginal incision, and through at least one of;

(i) an obturator foramen such that at least part of the tissue repair device exits the body;

(ii) an abdominal wall such that at least part of the tissue repair device exits the body;

or

(iii) perineal skin such that at least part of the tissue repair device exits the body;

(c) inserting a first end of a second pair of tissue repair devices through a vaginal incision, and through at least one of;

(i) an obturator foramen such that at least part of the tissue repair device exits the body;

(ii) an abdominal wall such that at least part of the tissue repair device exits the body;

or

(iii) perineal skin such that at least part of the tissue repair device exits the body;

(d) positioning the support portion to provide support to at least one of a vaginal wall and a uterus.

44. The method of claim 43, further comprising the step of adjusting the position of the support portion to provide support to at least one of a vaginal wall and a uterus.

45. The method of claim 44, wherein the step of adjusting the position of the support portion is performed within 72 hours of inserting the device in the body.
