Abstract
A binding device and method of use for providing a compressive force across tissue boundaries to promote healing. The binding device includes a strap adapted to form a loop about injured tissue and a tension member attached to the strap, wherein the tension member maintains a predetermined stress level in the loop which compresses the edges of the tissue together to foster healing. The tension member is preferably a shape memory effect alloy, such as nitinol, a nickel-titanium alloy. The binding device also includes a one-way locking mechanism which keeps the strap in a loop.
Claims14
A binding device comprising:
- a strap;
- a one-way locking mechanism for securing said strap in the form of a loop;
- and
- a tension member attached to said strap, wherein said tension member maintains a substantially constant predetermined tension level within said strap.
A binding device comprising:
- a strap;
- and
- a tension member attached to said strap, wherein said tension member maintains a substantially constant predetermined tension level within said strap, wherein said tension member is a pseudoelastic shape memory effect alloy.
A surgical binding device for binding tissue, said binding device comprising:
- a strap adapted to be positioned across adjacent edges of tissue and tightened for holding the tissue in close proximity;
- and
- a tension member attached to said strap wherein said tension member is a pseudoelastic shape memory effect alloy which maintains a substantially constant predetermined tension level in said strap, said shape memory alloy including stable austenite below martensite deformation temperature (Md).
A surgical binding device for binding tissue, said binding device comprising:
- a strap adapted to be positioned across adjacent edges of tissue and tightened for holding the tissue in close proximity, wherein said strap is provided with a piercing end for insertion through the tissue and has a base opposite said piercing end and a tie portion, said base adapted to irreleasably receive said piercing end and said tie portion to form a tightenable loop;
- and
- a tension member attached to said strap wherein said tension member maintains a substantially constant predetermined tension level in said strap.
A surgical binding device comprising:
- a base and a locking member;
- a strap adapted to form a loop for holding tissue in close proximity;
- and
- a tension member connecting said base to said strap, wherein said tension member maintains a substantially constant tension in said loop.
A method of binding together injured tissue under a compressive force to promote healing, comprising the steps of:
- (a) drawing together in close proximity opposing edges of injured tissue by tightening a strap which forms a loop about the injured tissue;
- and
- (b) tightening said strap so that a tension member within said strap exerts a substantially constant tension within said loop to maintain the tissue in close proximity.
