METAL ALLOYS FOR MEDICAL DEVICES
A medical device and a method and process for at least partially forming a medical device, which medical device has improved physical properties.
Device with an open cell element
Medical devices are disclosed. For example, a medical device includes an elongated member. The medical device includes a hole forming surface along a portion of the elongated member. The medical device includes an open cell element in physical communication with the elongated member. The open cell element is configured to house at least a first portion of a biocompatible substance.
SWELLABLE POLYMER HYBRID FIBRES FOR A SLEEVE OF AN INTRALUMINAL ENDOPROSTHESIS
An intraluminal endoprosthesis such as a stent has a metallic supporting structure and a sleeve surrounding the supporting structure. The sleeve can include fibres which are applied to an outer side of the supporting structure. The fibres each have a polymer core and a hydrogel casing connected thereto. The sleeve can also be formed from a fibre mixture of polymer and hydrogel fibres.
Medical Device That Includes a Rhenium Metal Alloy
A medical device that is at least partially formed of a rhenium metal alloy.
Biodegradable, magnesium-containing bone screws, methods for their preparation and medical applications therefore
The invention relates to a biodegradable, magnesium-containing bone screw for implanting into a patient body for use in medical applications, such as, orthopedic, craniofacial and cardiovascular surgery. The bone screw has a head, shaft and tip. The thickness of the head is greater than the thickness of conventional bone screws. The shaft includes both a non-threaded and a threaded portion. The tip is non-threaded and pointed, such as, conical in shape. The composition of the bone screws provide for improved biodegradability and biocompatibility, and the features of the structure of the bone screws facilitate guidance and placement during implantation as well as reduce the potential for mechanical failures.
IMPLANTABLE GRAFT AND METHODS OF MAKING SAME
The present invention relates to an implantable endoluminal graft comprised of a microporous thin-film metal covering having a plurality of openings and a structural support element underlying and physically attached to the microporous thin-film metal covering, the microporous thin-film metal covering having shape memory properties.
STENT HAVING FUNCTIONAL MATERIAL COATED ON CELL SPACE THEREOF
The present invention relates to a stent having a functional material coated on a cell space (safe coating space) thereof. The stent of the present invention, as a stent having a space for mounting and coating drugs and other materials for expanding the functions of the stent, is highly feasible as an actual product in consideration of the structure, transfer device, and manufacturing process of the stent as a whole, and secures a coating space (safe coating space) of a functional material in a cell of the stent through quantitative and qualitative modelling. Since an additional increase in volume does not occur even when the stent is press-mounted in a transfer device as a result of mounting a radio marker or a drug in the coating space, the stent of the present invention has excellent radio opacity without obstructing the loading and deployment of the stent, and may stably mount a great amount of a functional drug.
PROTECTED MAGNESIUM ALLOYS FOR BIORESORBABLE STENTS
Biodegradable magnesium alloy implantable medical devices are protected to delay onset of corrosion, and thus biodegradability, or to corrode more uniformly. The protection allows for extended effective use of the devices while maintaining biodegradability. Examples of protective coatings include conversion coatings that at least partially remove exposed second phases from a surface of the magnesium alloy and coatings that provide a barrier between water and the surface of the magnesium alloy.
Protected magnesium alloys for bioresorbable stents
Biodegradable magnesium alloy implantable medical devices are protected to delay onset of corrosion, and thus biodegradability, or to corrode more uniformly. The protection allows for extended effective use of the devices while maintaining biodegradability. Examples of protective coatings include conversion coatings that at least partially remove exposed second phases from a surface of the magnesium alloy and coatings that provide a barrier between water and the surface of the magnesium alloy.
Radially rigid and longitudinally flexible multi-element intravascular stent
A multi-element, vascular stent may be used to maintain or enhance patency of a blood vessel. The stent may be used in peripheral blood vessels, which may be long and/or tortuous. By using multiple, separate stent elements that are balloon expandable, the multi-element stent may be stronger than a traditional self-expanding stent but may also be more flexible, due to its multiple-element configuration, than a traditional balloon-expandable stent. The distance between stent elements may be based on characteristics of the stent and the target vessel location such that the stent elements do not touch one another during skeletal movement. Thus, the multi-element, vascular stent described herein may be particularly advantageous for treating long lesions in tortuous peripheral blood vessels.
