High molecular weight copolymers of L(-) lactide and glycolide are prepared by heating a mixture of the monomers at 200.degree.C. in the presence of a stannous octoate catalyst. The copolymers so obtained may be extruded to form filaments having utility as absorbable sutures.

McGregor Walter: Controlled release suture. Ethicon, Eberhardt Wayne R, Kell Robert W, June 24, 1975: US3890975 (85 worldwide citation)

A needle-suture combination is provided which has a suture pull-out value between 3 ounces and 26 ounces. The suture, one end of which is sized with a resin and smaller in diameter than the rest of the suture, is manufactured by placing the suture under tension, immersing a small section of the sutu ...

Absorbable surgical sutures that are dimensionally stable within the body may be prepared by the extrusion of polylactide polymer, including copolymers of L(-) lactide with up to 35 mole percent of glycolide. Said polymers are characterized by an inherent viscosity of at least 1.0, and the extruded ...

Thyen Eberhard Heinrich: Suture package. Ethicon, Kell Robert W, December 31, 1974: US3857484 (51 worldwide citation)

A surgical suture package, primarily for double armed multi-strand sutures, retains each individual suture in a predetermined sinusoidal configuration within adjacent but separate compartments. Notches along one edge of the package secure the armed ends of each suture which are held in place within ...

Beroff Howard, Ferguson Robert G: Lateral release suture. Ethicon, Kell Robert W, March 26, 1974: US3799169 (45 worldwide citation)

A surgical needle is manufactured with an open channel at the blunt end thereof sized to receive a suture. The suture is bonded to the channel with an adhesive that prevents 'pull-out' of the suture as it passes through tissue. After suturing, the surgeon may easily remove the needle from the suture ...

Hunter Alastair Wilson, Rosen Neil Howard: Covered suture. Ethicon, Kell Robert W, February 12, 1974: US3791388 (25 worldwide citation)

Surgical sutures having an improved knot strength are constructed with a central core of multifilament yarn that has been impregnated with an adhesive binder. The adhesive binder coated core yarn is covered with a ribbon-like helical winding of multifilament yarn and the composite structure is hot s ...

The disclosure is directed to a device for monitoring the thermodynamic state of a fluid flowing through a conduit. Electromechanical transducers (12) and (15) are acoustically coupled to a conduit (13) by securing straps (14). The piezoelectric crystal (17) of transducer (12) converts an electrical ...
