Disclosed are a sustained-release injection formulation containing a biodegradable polymer double microcapsule that contains a conjugate of poly-L-lactic acid (hereinafter referred to as “PLLA”) filler and hyaluronic acid (hereinafter referred to as “HA”) and is capable of controlling the release rate of PLLA, and a method of preparing the same.
INTRAOPERATIVE USES OF SETTABLE SURGICAL COMPOSITIONS
Provided herein are settable surgical compositions and methods for their intraoperative use.
HYDROLYTICALLY DEGRADABLE POLYSACCHARIDE HYDROGELS
Provided are polysaccharide compositions capable of controllable hydrolytic degradation and suitable for controlled release of therapeutic agents. Also provided are methods for synthesizing such compositions and a variety of applications in which the compositions may be used.
Optimized Stent Jacket with Large Apertures
An intravascular device configured to treat an aneurysm that includes a support structure including metal struts configured to be positioned in a body lumen and defining a central fluid passage that extends axially along the support structure, and a knitted mesh cover disposed over an exterior thereof and across a radial arc and along a length of the support structure sufficient to exceed an opening of an aneurysm to be treated, and the cover includes a polymer fiber having a diameter of at least 40 nanometers to 30 microns and apertures therethrough, the apertures being sized to prevent blood from passing through the device to prevent further expansion of the aneurysm. Devices including apertures that are at least 20 microns and sized to minimize or prevent an aneurysm-filling material from exiting the aneurysm through the knitted mesh cover and support structure, and methods of stenting, are also encompassed.
Biomimetic nanofiber tissue scaffolds
A biomimetic tissue scaffold for repairing an elongated tissue in need of repair can comprise a plurality of coiled flexible polymeric ribbons having a surface on which is formed an array of nanofibers, the ribbons forming a tubular body defining a first open end in which a first end of the elongated tissue is receivable, a second open end in which a second end of the elongated tissue is receivable, and a lumen extending between the first and second open ends.
Metal implant for generating soft tissue and attaching to an implant
One embodiment of the present invention is directed to compositions and methods for enhancing attachment of soft tissues to a metal prosthetic device. In one embodiment a construct is provided comprising a metal implant having a porous metal region, wherein said porous region exhibits a nano-textured surface.
POLYMER IMPLANTS
The present technology relates to polymer implants. In some embodiments, the polymer implant may have a volume having minimum cross-sectional dimension of 400 μm. The polymer implant may be configured to be implanted within a mammalian body for at least 3 days without undergoing core acidification.
BONE IMPLANT AND SYSTEMS AND COATINGS FOR THE CONTROLLABLE RELEASE OF ANTIMICROBIAL METAL IONS
Antimicrobial metal ion coatings and implants including them. In particular, described herein are coatings including an anodic metal (e.g., silver and/or zinc and/or copper) that is co-deposited with a cathodic metal (e.g., palladium, platinum, gold, molybdenum, titanium, iridium, osmium, rhodium, manganese, niobium or rhenium) on a substrate so that the anodic metal is galvanically released as antimicrobial ions when the apparatus is exposed to a bodily fluid. The anodic metal may be at least about 25 percent by volume of the coating, resulting in a network of anodic metal with less than 20% of the anodic metal in the coating fully encapsulated by cathodic metal. The implant may be configured as an implant such as a bone-screw or intramedullary rod-like body configured to receive a treatment cartridge having a coating as described.
PRO-HEALING, PRO-REGENERATIVE NANOFIBROUS COATING FOR MEDICAL IMPLANTS
The present invention relates to a medical implant, and more particularly, to a vascular implant having a dual coating structure for preventing in-stent restenosis and thrombosis. In one embodiment, the invention contemplates a vascular stent with a coating comprising a hydrophobic, degradable core with a coaxial sheath comprising at least one polyethylene-glycol derivative. In one embodiment, said at least one polyethylene-glycol derivative comprises polyethylene-glycol dimethacrylate.
Biopolymer compositions, scaffolds and devices
Compositions and blends of biopolymers and copolymers are described, along with their use to prepare biocompatible scaffolds and surgically implantable devices for use in supporting and facilitating the repair of soft tissue injuries.
