Abstract
A non-invasive device for anchoring a suture includes a sheet to which a suture can be attached and an adhesive that can affix the sheet to bone. The method provides placing effective amount of an adhesive on a bone and attaching the suture to the adhesive and allowing the adhesive to set.
Claims17
A method of affixing a suture to the outer surface of a bone in a minimally invasive manner comprising applying an adhesive to the outer surface of the bone;
- and bonding the suture onto the outer surface of the bone, wherein the adhesive comprises a calcium phosphate and a compound of the following formula:
- where A is O, CH2, or S;
- R is H, NH2, NHCO(CH2)tCH3 where t is 0 to 2, NH(CH2)xCH3 where x is 0 to 3, NR1R2 where R1 is (CH2)yCH3 and R2 is (CH2)yCH3 where y is 0 to 2, (CH2)zCH3 where z is 0 to 3;
- m is 0 to 1;
- and n is 0 to 3;
- and
- when set, the adhesive has a separation force of greater than or equal to about 30 N.

A method of attaching a suture anchor to the outer surface of bone comprising:
- applying an adhesive to the outer surface of a bone;
- and bonding the suture anchor to the outer surface of the bone, wherein the suture anchor comprises a relatively flat sheet and a suture attached to the sheet, and the adhesive comprises a calcium phosphate and a compound of the following formula:
- where A is O, CH2, or S;
- R is H, NH2, NHCO(CH2)tCH3 where t is 0 to 2, NH(CH2)xCH3 where x is 0 to 3, NR1R2 where R1 is (CH2)yCH3 and R2 is (CH2)yCH3 where y is 0 to 2, (CH2)zCH3 where z is 0 to 3;
- m is 0 to 1;
- and n is 0 to 3.
