Lubricious extruded medical tubing

A medical tube having improved lubricity is disclosed. The medical tube is produced by extruding a polymer material blended with a lubricity enhancing additive through a resilient die. The polymer material can be medical-grade high-density polyethylene, and the lubricity enhancing additive can be a silicone-based or alloy-based material. The medical tube can include one or more internal elongated protuberances so as to reduce the internal surface area of the medical tube available to generate friction on a guide wire inserted or withdrawn through the medical tube.

Distal access aspiration guide catheter system and methods for delivering implantable devices, catheters, or substances in or near and/or restoring flow through body lumens, such as blood vessel lumens are described. A Distal access aspiration guide catheter having a proximal, medial, and distal possessing high flexibility, high resistance to kinking and a large lumen to wall thickness ratio.

BODY-INSERTABLE MEDICAL CABLE WITH ANTIMICROBIAL CONDUITS AND FILL REGIONS
20190175795 · 2019-06-13 ·

A flexible body-insertable cable includes conduits and cables. Each conduit has an antimicrobial material defining interior wall surfaces thereof. Each cable provides a function selected from the group consisting of mechanical functions, electrical functions, and optical functions. A solid antimicrobial material encases each of the conduits and each of the cables for retaining the conduits and cables in a spaced-apart and longitudinally-extending arrangement along a length of the solid antimicrobial material.

VACUUM MEMBRANE THERMOFORMED POLY-4-HYDROXYBUTYRATE MEDICAL IMPLANTS
20190167834 · 2019-06-06 ·

Methods to produce thermoformed implants comprising poly-4-hydroxybutyrate homopolymer, copolymer, or blend thereof, including surgical meshes, have been developed. These thermoforms are preferably produced from porous substrates of poly-4-hydroxybutyrate homopolymer or copolymer thereof, such as surgical meshes, by vacuum membrane thermoforming. The porous thermoformed implant is formed by placing a porous substrate of poly-4-hydroxybutyrate homopolymer or copolymer thereof over a mold, covering the substrate and mold with a membrane, applying a vacuum to the membrane so that the membrane and substrate are drawn down on the mold and tension is applied to the substrate, and heating the substrate while it is under tension to form the thermoform. The method is particularly useful in forming medical implants of poly-4-hydroxybutyrate and copolymers thereof, including hernia meshes, mastopexy devices, breast reconstruction devices, and implants for plastic surgery, without exposing the resorbable implants to water and without shrinking the porous substrate during molding.

HIGH BARRIER ELASTOMER FECAL CATHETER OR OSTOMY POUCH
20190151134 · 2019-05-23 ·

A fecal catheter or ostomy pouch made of an odor barrier material including a thermoplastic elastomer, odor barrier modifier and an antiblocking agent.

NON-COMPLIANT MEDICAL BALLOON HAVING AN INTEGRAL NON-WOVEN FABRIC LAYER
20190143084 · 2019-05-16 ·

A non-compliant medical balloon may be changed from a deflated state to an inflated state by increasing pressure within the balloon. The non-compliant medical balloon is composed of randomly oriented fibers forming an angle. The angle remains substantially unchanged when the balloon changes from a deflated state to an inflated state.

ROD-SHAPED BODY

The invention relates to a rod-shaped body (1) comprised of one or more filaments (2) and of a non-ferromagnetic matrix material (3). The matrix material (3) surrounds the filament(s) (1) and/or adheres them to one another. The rod-shaped body is also comprised of a dopant consisting of particles that generate magnetic resonance tomographic artifacts that is introduced into the matrix material (3). Rod-shaped bodies of this type can be used to construct guide wires, catheters and other instruments to be used in minimally invasive surgical interventions.

Distal access aspiration guide catheter

Distal access aspiration guide catheter system and methods for delivering implantable devices, catheters, or substances in or near and/or restoring flow through body lumens, such as blood vessel lumens are described. A Distal access aspiration guide catheter having a proximal, medial, and distal possessing high flexibility, high resistance to kinking and a large lumen to wall thickness ratio.

DRUG-ELUTING TUBES FOR IMPROVED PATIENT CARE
20240245834 · 2024-07-25 ·

The present invention provides improved drug-eluting tube devices. In some embodiments, the tube devices deliver analgesics directly at sites of internal discomfort, including, but not limited to, internal membranes and implant entry sites. In some embodiments, the tube devices can be reloaded with drug in situ. In some embodiments, the tube devices comprise lubricating coatings to reduce painful friction with internal membranes. In some embodiments, the tube devices further include flexible and pliable regions that dampen force transmission to implanted sites, such as by inadvertent pulling.

Stiff and strong hydrogels, production method and uses thereof

The present disclosure relates to the development of hydrogels with extreme stiffness and high-strength. In particular, an hydrogel comprising poly(2-hydroxyethyl methacrylate) and graphene material with a specific oxidation degree. The hydrogels of the present disclosure may be used in medicine, veterinary or cosmetic, namely as scaffold, cartilage, intervertebral disc and blood contact device such as: catheters, vascular grafts, heart valves, stents, artificial kidneys, artificial lungs, ventricular assist devices or drug delivery system. Uses in other areas can be envisaged, like in soft robotics, packaging, sealing and sensors.
