1. A method of forming a suture to be used in a surgical procedure applied to tissue, comprising:
- (a) providing an elongated suture body having a periphery; and
(b) forming retainers along the elongated suture body by applying molten material to portions of the periphery of the elongated suture body and cooling the material to form the retainers,wherein step (b) includes using one or more dispensers to dispense the molten material onto the portions of periphery of the elongated suture body and moving at least one of the elongated suture body and one of said one or more dispensers, relative to one another, during the dispensing of the molten material.

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 having a periphery, and a plurality of retainers formed from molten material applied to portions of the periphery. The retainers can extend from and be arranged along at least a segment of the elongated suture body. The retainers can be formed by applying molten material to portions of the periphery of the elongated suture body and cooling the material to form the retainers.

-
(a) providing an elongated suture body having a periphery; and (b) forming retainers along the elongated suture body by applying molten material to portions of the periphery of the elongated suture body and cooling the material to form the retainers, wherein step (b) includes using one or more dispensers to dispense the molten material onto the portions of periphery of the elongated suture body and further includes controlling the speed and/or acceleration at which the one or more dispenser and/or the elongated suture body are moved during the dispensing of the molten material, to thereby affect a shape and/or size of the retainers formed using the one or more dispenser.
