Abstract
Abstract A tissue anchoring system includes a tissue anchor affixed to an end of a cable and supported for insertion on a delivery device, the manipulation of which permits placement of the anchor on a far side of the tissue. A tensioning, crimping and cutting tool designed for use along the cable's longitudinal axis, thus reducing the number of incisions required. A suture anchoring system is also described for introducing a loop of suture into a surgical site and anchoring it, for instance, across a tear in soft tissue.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
152 words
An anchor system, comprising: an elongated flexible member having a diameter, a proximal end, a distal end and a longitudinal axis; and an anchor having an open proximal end, a closed distal end, a central portion between said proximal end and said distal end and a longitudinal axis extending between said proximal end and said distal end, said anchor including a longitudinal bore extending between said closed distal end and said open proximal end and a longitudinal slot extending longitudinally from said proximal end to said central portion, the slot having a width greater than the flexible member diameter, said flexible member distal end affixed within said bore; said anchor moveable relative to said flexible member between a first position wherein the longitudinal axes of said flexible member and said anchor are generally parallel and a second position wherein the longitudinal axes of said flexible member and said anchor are generally perpendicular.
Claim 2
Dependent Claim
152 words
An anchor system, comprising: an elongated flexible member having a diameter, a proximal end, a distal end and a longitudinal axis; and an anchor having an open proximal end, a closed distal end, a central portion between said proximal end and said distal end and a longitudinal axis extending between said proximal end and said distal end, said anchor including a longitudinal bore extending between said closed distal end and said open proximal end and a longitudinal slot extending longitudinally from said proximal end to said central portion, the slot having a width greater than the flexible member diameter, said flexible member distal end affixed within said bore; said anchor moveable relative to said flexible member between a first position wherein the longitudinal axes of said flexible member and said anchor are generally parallel and a second position wherein the longitudinal axes of said flexible member and said anchor are generally perpendicular.
Claim 3
Dependent Claim
44 words
The anchor system of claim 1, wherein said anchor includes a curved bearing surface on said central portion adjacent said slot, said curved bearing surface area adapted to increase the surface of contact between the flexible member and the anchor in said second position.
Claim 4
Dependent Claim
17 words
The anchor system of claim 1, wherein said flexible member is affixed in said bore by adhesive.
Claim 5
Dependent Claim
22 words
The anchor system of claim 1, wherein said flexible member is affixed in said bore by crimping said anchor adjacent said bore.
Claim 6
Dependent Claim
56 words
The anchor system of claim 1, wherein the proximal end of said anchor is angled with respect to said longitudinal axis, the proximal end opposite said slot extending more proximally than the proximal end adjacent said slot, whereby engagement of said angled proximal end with a surface tends to rotate said anchor toward said second position.
Claim 7
Dependent Claim
32 words
The anchor system of claim 1, wherein said flexible member is fixedly attached to said anchor and said flexible member deforms to permit movement between said first position and said second position.
Claim 8
Dependent Claim
15 words
The anchor system of claim 1, wherein said anchor is biased toward said second position.
Claim 9
Dependent Claim
29 words
The anchor system of claim 7, wherein said flexible member is a cable and said cable is bent adjacent said anchor to create said bias towards said second position.
Claim 10
Dependent Claim
174 words
An anchor system, comprising: an elongated flexible member having a diameter, a proximal end, a distal end and a longitudinal axis; and an anchor having a proximal end, a distal end, a central portion between said proximal end and said distal end and a longitudinal axis extending between said proximal end and said distal end, said distal end bigger than said proximal end, said proximal end adapted for receipt within a delivery device, said distal end sized to prevent receipt within the delivery device, said anchor including a longitudinal slot extending longitudinally from said proximal end to said central portion, the slot having a width greater than the flexible member diameter, said flexible member distal end interconnected with said anchor; said anchor moveable relative to said flexible member between a first position wherein the longitudinal axes of said flexible member and said anchor are generally parallel when said proximal end is disposed within said delivery device and a second position wherein the longitudinal axes of said flexible member and said anchor are generally perpendicular.
Claim 11
Dependent Claim
174 words
An anchor system, comprising: an elongated flexible member having a diameter, a proximal end, a distal end and a longitudinal axis; and an anchor having a proximal end, a distal end, a central portion between said proximal end and said distal end and a longitudinal axis extending between said proximal end and said distal end, said distal end bigger than said proximal end, said proximal end adapted for receipt within a delivery device, said distal end sized to prevent receipt within the delivery device, said anchor including a longitudinal slot extending longitudinally from said proximal end to said central portion, the slot having a width greater than the flexible member diameter, said flexible member distal end interconnected with said anchor; said anchor moveable relative to said flexible member between a first position wherein the longitudinal axes of said flexible member and said anchor are generally parallel when said proximal end is disposed within said delivery device and a second position wherein the longitudinal axes of said flexible member and said anchor are generally perpendicular.
Claim 12
Dependent Claim
41 words
The anchor system of claim 9, wherein said anchor includes an external shoulder disposed between said proximal end and said distal end, said shoulder adapted to abuttingly engage said delivery device to limit movement of said anchor within said delivery device.
Claim 13
Dependent Claim
57 words
The anchor system of claim 10, wherein said delivery device is sufficiently rigid to advance said anchor through tissue, said delivery device having a distal end adapted to releasably receive said proximal end of said anchor and abuttingly engage said shoulder, the distal end of said anchor extending distally beyond the distal end of said delivery device.
Claim 14
Dependent Claim
15 words
The anchor system of claim 1, wherein said flexible member is formed of bioresorbable material.
Claim 15
Dependent Claim
14 words
The anchor system of claim 1, wherein said anchor is formed of bioresorbable material.
Claim 16
Dependent Claim
18 words
The anchor system of claim 1, wherein said flexible member and said anchor are formed of bioresorbable material.
Claim 17
Dependent Claim
30 words
The anchor system of claim 1, wherein said anchor is substantially cylindrical and has a second diameter, said second diameter being less than twice the diameter of said flexible member.
