  • Patent number: 11007296
    Abstract: A drug-eluting self-retaining suture comprises a filament, a plurality of retainers, and a drug impregnated in or coated on the filament. The shape and distribution of retainers modifies the in vivo release kinetics of the drug. The drug release kinetics may be modified uniformly or region by region. The self-retaining suture may for example be used for reattaching severed nerves and release nerve growth factor or other regeneration accelerating agents into the region of the nerve injury.

  • Patent number: 8961560
    Abstract: A marked heterofunctional suture thread has two or more sections having different features. One or more sections of the suture thread are provided with laser-marked and non-laser marked indicia in order that they may be identified and differentiated from other sections. The suture thread may have retainers on the surface of one or more sections such that the suture thread can engage and retain tissue without knots. The markers may be used to indicate fixed features of a section of suture thread such as the presence and/orientation of retainers. In particular embodiments, laser-marked and non-laser marked indicia are used to identify the transition section of a bidirectional self-retaining suture.

  • Publication number: 20130226234
    Abstract: A self-retaining braided suture comprises a braided suture with tissue retainers formed on the surface such that the suture can engage and retain tissue without knots. The suture includes a plurality of braided fibers which may be covered by a non-braided sheath of a material which enhances the formation, elevation and/or deployment of the retainers. The retainers can be formed so as not to disrupt the braided fibers. The self-retaining braided suture has properties which enhance the tensile strength of the suture while preserving flexibility and durability. Methods for manufacturing and using self-retaining braided suture are also described.

  • Publication number: 20130204295
    Abstract: A tissue retaining device includes a flexible suture thread having a surface microtexture and/or nanotexture. The surface microtexture and/or nanotexture filament is directional in that the resulting suture thread has a lower resistance to moving through tissue in the direction of intended deployment than in the reverse direction. A variety of alternative asymmetric textural elements and/or distributions of textural elements are disclosed. Methods for manufacturing the surface microtexture and/or nanotexture are also described.
