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 anchoring device having an elongate body at a proximal portion, a distal portion of the elongate body forming a loop at a distal portion of the anchoring device, and a pledget placed over the elongate body adjacent a proximal portion of the loop. The loop further includes a plurality of anchors disposed along a surface thereof and the loop. Methods for securing anchoring devices of the present disclosure are also disclosed.

Anchoring device

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.

Method of forming barbs on a suture

The present disclosure is directed to a method and system for the repair of ventral hernias. The method includes the steps of providing a needle; providing a barbed suture having a distal end attached to the needle; providing a surgical mesh; rolling the surgical mesh, the barbed suture, and the needle to form a rolled mesh having the needle oriented substantially parallel to a longitudinal axis of the rolled mesh; transferring the rolled mesh into a body cavity via a laparoscopic device; unrolling and laying the surgical mesh under a ventral hernia in an abdominal wall; threading the needle and barbed suture through the surgical mesh and the abdominal wall; and trimming the barbed suture.

Ventral hernia repair with barbed suture

An anchoring device includes an elongate body having a proximal portion and a distal portion. The proximal portion of the elongate body terminates in a free end and the distal portion forms a loop. The loop includes a proximal portion and a distal portion. and further includes a plurality of anchors disposed along a surface thereof. The plurality of anchors are oriented toward the proximal portion of the elongate body to limit movement of the loop through tissue. A pledget is disposed adjacent the proximal portion of the loop. Methods for securing anchoring devices of the present disclosure are also disclosed.

A wound closure device includes an elongated body with proximal and distal ends having a plurality of through-holes along the length and defining a longitudinal axis with a plurality of surface features extending away from the axis. The proximal end is configured and dimensioned to pass through body tissue and thereafter be selectively passed through at least one of the plurality of through-holes such that at least one of the surface features also passes through the through-hole thereby forming a locked closed loop to secure body tissue held therein.

Wound closure device

A medical device includes an elongate body having a proximal portion and a distal portion. The proximal portion of the elongate body terminates in a free end and the distal portion forms a loop. The loop includes a proximal portion and a distal portion, and a plurality of barbs disposed along a surface thereof. A pledget is disposed adjacent the proximal portion of the loop. The elongate body, loop, and/or barbs may be formed from shape memory polymers that are configured to change shape in vivo upon application of energy. Methods for securing medical devices of the present disclosure are also disclosed.

A compound barb medical device includes a body portion and at least one barb extending therefrom. The at least one barb defines an inner surface. The inner surface includes a first portion disposed at a first orientation relative to a longitudinal axis of the body portion and a second portion disposed at a second orientation relative to the longitudinal axis. The at least one barb is made from a shape memory material which can be deformed into a temporary shape from a permanent shape. The barb projects from the body portion in a first position relative to the body portion when in the permanent shape and in a second position when in the temporary shape.
