A compound barb medical device is provided which includes an elongated body having at least one barb formed along the length of the body, the barb defining an inner surface with a first portion disposed at a first orientation relative to a longitudinal axis of the elongated body, and a second portion disposed at a second orientation relative to the longitudinal axis. Optionally, the barb defines a third portion disposed at a third orientation relative to the longitudinal axis. A method for forming a compound barb on a medical device is also provided.

Compound barb medical device and method

An active anvil assembly for use in forming a looped suture is provided. The active anvil assembly includes an anvil member, a first sensor operably connected to the anvil member, and a control assembly. The first sensor is configured for measuring at least one of force, torque, and distance feedback. Also provided are systems and methods for forming a looped suture including an active anvil assembly.

System and method for making tapered looped suture

A station for cutting a barb suture is provided. The barb cutting station includes a suture transport assembly for supporting a first suture, a first knife assembly for forming barbs on the first suture, and a first clamp and position assembly for approximating the at least first suture towards the at least first knife assembly. The barb cutting station may further include at least a first suture cutting mechanism configured for severing the at least first suture when a defect is detected. The station may also include at least a first visual inspection assembly configured for detecting defective barbs.

System and method for forming barbs on a suture

Barbed medical devices include a crown interconnecting a pair of legs and at least one barb extending from each of the legs. The at least one barb may define an inner surface with a first portion disposed at a first orientation relative to a longitudinal axis of the leg, a second portion disposed at a second orientation relative to the longitudinal axis, and optionally, a third portion disposed at a third orientation relative to the longitudinal axis of the leg.

A method is provided for forming a barbed medical device which includes the steps of providing a blank workpiece and forming at least one barb on the blank workpiece by applying vibrational energy to a tool and bringing the tool and the blank workpiece into contact with each other at an angle such that the tool cuts into the surface of the blank workpiece. A barbed medical device formed by this method is also provided.
