Embodiment Construction

[0024] Before explaining the present invention, it may be helpful for the understanding of the present invention to first set forth the definitions of specific terms used below.

[0025] "Self-retaining system" refers to a self-retaining suture with a device for deploying the suture into tissue. Such deployment devices include, without limitation, suture needles and other deployment devices as well as sufficiently hard and sharp ends on the suture itself to penetrate tissue.

[0026] "Self-retaining suture" refers to a suture that does not require a knot or suture anchor at its end in order to maintain its deployed position during a surgical procedure. These sutures may be monofilament sutures or braided sutures, are positioned in tissue during both deployment and fixation stages, and include at least one tissue retainer.

[0027]"Tissue retainer" (or simply "retainer" or "barb") refers to a suture element having a retainer body protruding from the suture body and a retainer ...

Abstract

Provided herein are sutures to be used in a procedure applied to tissue, and methods for forming such sutures. A suture can include an elongated suture body and a plurality of heat-contact mediated retainers extending from and along the elongated suture body. The heat-contact mediated retainers can be formed by temporarily contacting the elongated suture body with one or more heated element.

Description

technical field [0001] The present invention relates generally to self-retaining sutures for surgery, methods of making self-retaining sutures for surgery, and uses thereof. Background technique [0002] Sutures are commonly used to close or bind together wounds in human or animal tissues, such as skin, muscles, tendons, internal organs, nerves, and blood vessels. Sutures can be formed from nonabsorbable materials such as silk, nylon, polypropylene, or cotton, or alternatively, sutures can be formed from bioabsorbable materials such as, but not limited to, glycolide, polydioxanone and ε-caprolactone homopolymers and / or copolymers. [0003] Sutures typically consist of filamentary sutures with sharp-pointed needles (attachment of sutures and surgical needles are described in US Patent Nos. described in No. 2004 / 0088003). [0004] Self-retaining sutures (often referred to as "barbed sutures") differ from conventional sutures in that they possess many tiny retainers (often b...
