Abstract
Methods and apparatuses are described for attaching tendons, ligaments, or other tissue to bone, which includes the use of adjustable head members positioned along filament members. Also disclosed are methods and apparatuses for mending breaks in tissue such as skin or meniscal layers tissue such as skin or meniscal layers skin by use of similar elements.
Claims10
A method for attaching a tissue to a bone, comprising the steps of:
- a) attaching a first end of a flexible, elongate, filament member to a bone, said filament member including a first protruding portion, and including a first reduced portion intermediate said first end and said first protruding portion, and defining a second end opposing said first end;
- b) threading said second end of said filament member through said tissue and through an internal hole defined by a head member, said head member also defining engagement means extending into said hole, said engagement means configured to engage said first protruding portion to a greater extent than said first reduced portion;
- c) urging said head member along said filament member toward said first end and away from said second end with a force sufficient to urge said engagement member across said protruding section of said filament member until said engagement member is positioned atop said reduced section and said tissue member is captured between said head member and said bone.

- b) threading said second end of said filament member through said tissue cord through a washer, said washer defining at least one spike, said washer being threaded such that said spike is directed toward from said bone;
- c) threading said second end of said filament member through an internal hole defined by a head member, said head member also defining engagement means extending into said hole, said engagement means configured to engage said first protruding portion to a greater extent than said first reduced portion;
- d) urging said head member along said filament member toward said first end and away from said second end with a force sufficient to urge said engagement member across said protruding section of said filament member until said engagement member is positioned atop said reduced section, said head member is biased against said washer member, said spike engages said tissue member, and said tissue member is captured between said washer member and said bone.
