Title: Multi-density all suture anchor
IPC: A61B17/56
Filed: 2022-03-01
Abstract: PROBLEM TO BE SOLVED: To provide an all-suture anchor made of a material that is optimal for generating bone compression and increasing interference fixation force after installation. 
     SOLUTION: An all-suture anchor generates bone compression and increases interference fixation force. The all-suture anchor includes a fibrous construct which is movable between a pre-deployment configuration and a deployed configuration. The fibrous construct has a first density. The all-suture anchor also includes a monofilament woven through the fibrous construct. The monofilament has a second density, which is different than the first density. The contrasting densities (i.e., irregularities) aid in the "locking" ability of the all-suture anchor by greater purchase in hard and soft bone. The all-suture anchor can have a variety of textures, barbs and rigidities that aid in creating irregularities within the bone surface for more secure fixation.
