METHODS OF ORIENTING MULTIFILAMENT YARN AND MONOFILAMENTS OF POLY-4-HYDROXYBUTYRATE AND COPOLYMERS THEREOF

Resorbable multifilament yarns and monofilament fibers including poly-4-hydroxybutyrate and copolymers thereof with high tenacity or high tensile strength have been developed. The yarns and fibers are produced by cold drawing the multifilament yarns and monofilament fibers before hot drawing the yarns and fibers under tension at temperatures above the melt temperature of the polymer or copolymer. These yarns and fibers have prolonged strength retention in vivo making them suitable for soft tissue repairs where high strength and strength retention is required. The multifilament yarns have tenacities higher than 8.1 grams per denier, and in vivo, retain at least 65% of their initial strength at 2 weeks. The monofilament fibers retain at least 50% of their initial strength at 4 weeks in vivo. The monofilament fibers have tensile strengths higher than 500 MPa. These yarns and fibers may be used to make various medical devices for various applications.

DEVICES FOR ASSISTING WITH HEART VALVE MANUFACTURING

An assistance system that can be used for prosthetic heart valve manufacturing or suturing procedures includes an automated fixture that can comprise an articulation arm and a target device holder. The target device holder can be positioned and oriented to reduce operator strain during a manufacturing or inspection process. The assistance system includes a user input device enabling the operator to move between positions to assist in such processes. The assistance system can also be trained by capturing sequences of position data corresponding to a manufacturing or inspection process.

Method and apparatus for coupling soft tissue to a bone

A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. The apparatus includes a member to pull the soft tissue implant into a femoral tunnel. The member includes a suture having first and second ends which are passed through first and second openings associated with the longitudinal passage to form a pair of loops. A collapsible tube is positioned about the suture. Application of tension onto the suture construction causes retraction of the soft tissue implant into the femoral tunnel and the collapse of the tube to form an anchor.

Methods and devices for threading sutures

Methods and devices are provided for anchoring suture to bone. In one embodiment, an elongate weave of fibers can be provided having a first portion with a first pick count and a second portion with a second pick count that is greater than the first pick count. The first portion can have a cross-section that deforms in response to a force that is applied thereto. The first portion can have a collapsible diameter and can have a bending stiffness that is lower than a bending stiffness of the second portion of the suture. The first portion can also have a first pattern that is different than a second pattern on the second portion of the suture. The first portion can be threaded into a suture anchor such that it can be doubled over upon itself. The present invention also provides exemplary sutures and drivers that can be used with the various methods and devices disclosed herein, or with other methods and devices known in the art.

Method for forming a mesh having a barbed suture attached thereto and the mesh thus obtained
10682215 · 2020-06-16 · ·

The invention relates to a method for forming a mesh having a barbed suture attached thereto, comprising the following steps: a) producing a knitted structure on a knitting machine comprising at least one needle-bed with three guide bars, on a length corresponding to N stitches ranging from 1 to N, wherein i) a first knit portion is produced along stitches ranging from 1 to x, where 1<x<N, ii) a second knit portion is produced for stitches ranging from (x+1) to N, in which the knitting pattern produces at least one weft stitched chain stitch, b) cutting the second knit portion on both sides of the weft stitched chain stitch and along an edge separating the second knit portion from the first knit portion, while maintaining the weft stitched chain stitch attached to the first knit portion. The invention also relates to the mesh obtained by this method.

SYSTEMS, DEVICES AND METHODS OF MAKING SURGICAL SUTURES HAVING REFORMED, REDUCED DIAMETER TIPS
20200163669 · 2020-05-28 ·

A method of making a surgical suture having a reformed tip includes providing an elongated fiber having a first end, a second end, a central axis extending between the first and second ends thereof, and an outer surface that defines a cross-sectional dimension of the elongated fiber, and compressing a center region of the elongated fiber that is located between the first and second ends thereof for reshaping the center region into a core mass and a deformed mass that extends laterally outside the cross-sectional dimension of said elongated fiber. The method includes separating the deformed mass of the center region from the core mass of the center region so that only the core mass remains for interconnecting the first and second ends of the elongated fiber, and after separating the deformed mass from the core mass, reshaping the core mass into a reformed mass having a reformed mass central axis that is offset from the central axis of the elongated fiber.

Surgical suture with soft core

A fastening element includes (a) a non-load bearing core, the non-load bearing core includes a first biocompatible polymer; and (b) a load bearing sheath, the load bearing sheath including a second biocompatible polymer, wherein the load bearing sheath surrounds the non-load bearing core. The fastening element can be used as a suture, shoe lace or rope. The non-load bearing core has a Durometer Hardness Type A value ranging from 15 to 30. The load bearing sheath is formed from a plurality of yarns, each yarn comprising a plurality of filaments in form of mono or multifilament of the second biocompatible polymer. Each yarn may have a tenacity at break value ranging from 30 cN/dtex to 45 cN/dtex.
