Synthetic heart valves composed of zwitterionic polymers
A prosthetic heart valve includes a plurality of synthetic polymeric leaflets. Each leaflet has a base polymer and a polymer coating at least partially disposed over the base polymer, wherein the polymer coating includes polymerized units of a monomer comprising a zwitterionic group when the polymer coating is exposed to an aqueous environment at a pH of about 7.4.
COMPOSITE ePTFE AND SILICONE SOFT TISSUE IMPLANTS TO MINIMIZE CAPSULAR CONTRACTURE, WEIGHT, INFECTION AND PALPABILITY
Methods, systems, apparatuses and devices for implantation in a soft-tissue biological environment that include a primary layer for containing a filler substance, an interface and a secondary layer, including embodiments where the secondary layer an ePTFE layer, the primary layer is a silicone layer, the interface is mechanical or adhesive and the tiller substance can include particulates and lattices.
Stent with non-round cross-section in an unexpanded state
A stent has a circumference and a plurality of members that define a lumen. The stent has three stable states, which include an unexpanded state, a partially deployed state, and a deployed state. The lumen has a first cross-sectional shape in the unexpanded state, a second cross-sectional shape in the partially deployed state and a third cross-sectional shape in the deployed state. The first cross-sectional shape of the lumen is different from the second and third cross-sectional shapes of the lumen, and the first cross-sectional shape of the lumen is a non-round shaped cross-sectional shape.
Artificial joint cup, magnetic control sputtering coating film device and preparation method thereof
The present invention aims at improving and upgrading the conventional devices based on the low temperature magnetron sputtering coating devices. Starting from the material systems, the invention provides a new material system and a manufacturing method thereof based on a high molecular weight polyethylene joint cup to solve the poor binding force problem between the film and the matrix, and the problems of easy oxidization and carbonization of high molecular weight polyethylene with low temperature magnetron sputtering technologies at the same time. On the above basis, the ultra-lubrication performance of graphite-like structure films and ultra-hardness of diamond-like structure films are utilized to construct a nano-scale multilayer structure DLC film alternatively coated with a graphite-like film and a diamond-like film. The present invention improves the wear resistance of high molecular weight polyethylene joint cups, and restricts low accuracy of joints due to creeping by constructing a new artificial hip joint cup of ultra-wear-resisting nano-scale multilayer structure DLC film with high hardness and self-lubricating capability.
Anti-thrombogenic medical devices
Medical devices that include a tubular member with a plurality of braided filaments, each filament crossing another of the filaments at a respective crossing point forming sidewall and a plurality of pores in the sidewall that are sized to inhibit flow of blood through the sidewall into an aneurysm to a degree sufficient to lead to thrombosis and healing of the aneurysm when the tubular member is positioned in a blood vessel and adjacent to the aneurysm, the pores have an average pore size that is less than or equal to about 500 microns when the tubular member is in an expanded state, the filaments possessing antithrombogenic surfaces to increase antithrombogenicity of the medical device with pores substantially free of webs formed by antithrombogenic material, such that fewer than 5% of the crossing points have webs formed by antithrombogenic material thereby permitting the pores to be substantially free of webs.
GORE-TEX COVERED BREAST IMPLANTS TO MINIMIZE CAPSULAR REACTION AND INFECTION WHILE REDUCING PALPABILITY
This invention relates generally to a breast implant having an ePTFE layer, a Silicone layer of a breast implant core, and an interface between the ePTFE layer and the Silicone layer.
Systems and methods for incontinence control
A system for managing female incontinence includes a body of biocompatible material configured to fit between the labia minora and the vestibule floor, the body having a surface configured to occlude the urethral meatus, an adhesive carried on at least a first portion of the surface and configured to provide a sealing engagement between the body and the urethral meatus, and a substance carried by at least one of the body and the adhesive and configured for controlling the odor of the general vaginal-urethral area of a female.
METHOD FOR USE OF A DOUBLE-STRUCTURED TISSUE IMPLANT FOR TREATMENT OF TISSUE DEFECTS
A method for use of a double-structured tissue implant or a secondary scaffold stand-alone implant for treatment of tissue defects. The double-structured tissue implant comprising a primary scaffold and a secondary scaffold consisting of a soluble collagen solution in combination with a non-ionic surfactant generated and positioned within the primary scaffold. A method of use of a stand-alone secondary scaffold implant or unit for treatment of tissue defects.
BIOABSORBABLE MESH FOR SURGICAL IMPLANTS
Described are methods, devices, and systems related to pelvic implants, including implants that include absorbable and non-absorbable materials.
Artificial acetabulum with multi-layer shell core composite structure
An artificial acetabulum having a multilayer shell-core composite structure includes a ceramic acetabular liner, a transition layer and an acetabular shell. The acetabular shell is made of a porous metal, a porous alloy or a porous toughened ceramic; the ceramic acetabular liner is made of a ceramic material; and the transition layer is made of a composite material comprising materials of the acetabular shell and the ceramic acetabular liner. The artificial acetabulum is manufactured through sintering a green body of successively stacked layers of the ceramic acetabular liner, the transition layer and the acetabular shell, and the green body of successively stacked layers is obtained through a powder co-injection molding process. The ceramic acetabular liner of the artificial acetabulum has a high rigidness, corrosion-proof and wear-proof performance. The acetabular shell of the artificial acetabulum has a high toughness and shock resistant performance.
