CONDUCTING SUTURES AND METHODS FOR FORMING AND USING SAME
Sutures including a surgical suture material and a conducting coating that has been applied to the surgical suture material are provided, wherein an electrical conductivity of the suture greater is than 500 S/cm per 1964 μm.sup.2 of cross-sectional area of the suture. In some instances, an electro-chemical impedance of the suture is less than 10 kOhms at 1 kHz per 1964 μm.sup.2 of cross-sectional area of the suture. In some instances, a diameter of the suture is 50-100 μm. In some instances, the conducting coating includes PEDOT:PSS. In some instances, the conducting coating further includes metal particles or metal flakes. In some instances, the suture further comprises: an insulating layer. In some instances, the insulating layer comprises at least one of Parylene-C, polyurethane, and a silicone elastomer. In some instances, the insulating layer was applied to the surgical suture material after the conducting coating was applied to the surgical suture material.
SMALL DIAMETER FIBER BRAID WITH CENTRAL CORE MEMBER
A cord comprises a braided sheath of strands having an outer surface, an inner surface, and a central hollow portion defined by the inner surface and having a volume and a core within the central hollow portion of the tubular braided sheath, such that when the cord is in a relaxed state the tubular braided sheath has a cylindrical shape and a relaxed volume of the central hollow portion wherein the core does not fill the relaxed volume of the central hollow portion of the tubular braided sheath; when the cord is in a longitudinal tensioned state, the tubular braided sheath elongates under the longitudinal tension such that a tensioned volume of at least a part of the central hollow portion of the tubular braided sheath is less than the relaxed volume; and the inner surface of the tubular braided sheath of tensioned volume contacts and cinches a surface of the core.
Operating room coating applicator and method
A disposable coating applicator container for applying a coating of a therapeutic agent upon an object to be coated. The disposable coating applicator container includes a sealable container, the sealable container having a container bottom, the container bottom having upwardly extending walls, each upwardly extending wall terminating in an upper edge, and a closure for sealing a device compartment formed in part by the upwardly extending walls, the closure adjacent to the upper edges of the upwardly extending walls; and a therapeutic agent positioned in fluid communication with the device compartment, wherein the disposable coating applicator container comprises a flexible material and is in the form of a bag-like structure.
FULLY-THREADED BIOABSORBABLE SUTURE ANCHOR
A suture anchor includes an anchor body having a longitudinal axis, a proximal end, and a distal end. The anchor body includes a central bore located at the proximal end and a passage extending between the central bore and the distal end. The central bore has a first dimension substantially perpendicular to the longitudinal axis, and the passage has a second dimension substantially perpendicular to the longitudinal axis less than the first dimension. The suture anchor includes a flexible strand extending through the passage, and a first knot formed in the flexible strand at the distal end has a third dimension greater than the second dimension to prevent the first knot from passing through the passage. A closed loop is positionable at least partially within the central bore and formed entirely by the flexible strand without forming any additional knots on the flexible strand extending proximally from the first knot.
MEDICAL DEVICES COATED WITH SHAPE MEMORY POLYMER FOAMS
An embodiment includes a system comprising: a substrate of a medical device; an un-foamed polyurethane coating directly contacting the substrate and fixedly attached to the substrate; a thermoset polyurethane shape memory polymer (SMP) foam, having first and second states, which directly contacts the polyurethane coating and fixedly attaches to the polyurethane coating; wherein the polyurethane coating fixedly attaches the SMP foam to the substrate. Other embodiments are described herein.
Low temperature cured silicone lubricious coatings
Novel, lubricious coatings for medical devices are disclosed. The coatings provide improved lubricity and durability and are readily applied in coating processes a low temperatures that do not deform the device. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.
Polypeptides and medical uses thereof
The present invention provides polypeptides comprising or consisting of an amino acid sequence derived from collagen type VI or a fragment, variant, fusion or derivative thereof, or a fusion of said fragment, variant of derivative thereof, wherein the polypeptide, fragment, variant, fusion or derivative is capable of killing or attenuating the growth of microorganisms. Related aspects of the invention provide corresponding isolated nucleic acid molecules, vectors and host cells for making the same. Additionally provided are pharmaceutical compositions comprising a polypeptide of the invention, as well as methods of use of the same in the treatment and/or prevention of microbial infections and in wound care. Also provided are a method of killing microorganisms in vitro and a medical device associated with the pharmaceutical composition.
SUTURE THREAD PRODUCTS
There is provided a product comprising a suture thread which, prior to being used to form a surgical suture, is in a stressed state which gives the suture thread a tendency to undergo lengthwise viscoelastic contraction. The suture thread undergoes viscoelastic contraction when in use as a surgical suture and this may promote wound healing to a greater extent than a conventional suture thread which does not undergo viscoelastic contraction.
Process of changing cross sectional shape within a textile
Methods, systems, and devices for changing cross-sectional sizes and/or shapes of flat braided sutures and the resulting constructs are disclosed. The flat braided sutures can have a textile first cross-sectional shape that can be changed to a textile second cross-sectional shape. The systems can have a heater and a die. The flat braided sutures can be movable through the heater and the die. When the flat braided sutures are in the heater, the flat braided sutures can be heatable from a textile first temperature to a textile second temperature greater than the textile first temperature. When the flat braided sutures are at the textile second temperature, the textile first cross-sectional shape can be changeable to the textile second cross-sectional shape.
