MESH CAP FOR AMELIORATING OUTPOUCHINGS
20200405347 · 2020-12-31 ·

A self-expandable occluding device can both cover the neck of an outpouching and serve as a permanent embolic plug thereby immediately stabilizing the outpouching. The self-expandable device effectively covers the neck of an outpouching with, for example, a mesh, or other at least partially occluding component, in a desired orientation across the neck of the outpouching without projecting into the parent vessel. The device incorporates elements which immediately stabilize the device in the outpouching, in effect, functioning as a permanent embolic plug. An embolic disc is combined with retention arms of flexible material, which deploy within the outpouching and provide immediate stabilization thereby retaining the occluding component or mesh across the neck of the outpouching. In illustrative embodiments, the arms are in the form of coils configured to deploy into three dimensional structures.

Adhesion prevention agent comprising injectable thermosensitive wood based-oxidized cellulose nanofiber

The present invention provides a method for preparing an injectable thermosensitive hydrogel for preventing adhesion including mixing methyl cellulose, polyethylene glycol, oxidized cellulose nanofibers and carboxymethyl cellulose. The injectable thermosensitive hydrogel for preventing adhesion is a sol at a low temperature and induces rapid gelation upon in vivo implantation due to thermosensitivity. In addition, the hydrogel can be rapidly changed into physical hydrogel without separate additives or chemical reaction during in vivo condition. In addition, the injectable thermosensitive hydrogel for preventing adhesion exhibits excellent biodegradability and biocompatibility, has no cytotoxicity, inhibits in vitro migration of rat bone marrow mesenchymal stem cells (rBMSCs), and exhibits anti-adhesion efficacy in a rat model of sidewall defect-cecum abrasion in vivo, thus being useful as an effective anti-adhesive agent.

IMPLANTABLE DEVICE WITH ENHANCED DRUG DELIVERY AREA

Disclosed is an implantable device with enhanced drug delivery area, wherein a pre-crimped stent assembly mounted on a balloon further comprises a homogenous coating of drug and associated polymeric matrix resulting in the formation of a circumferential cylindrical film formation, upon expansion of the balloon. The cylindrical film formation by the drug delivery medical devices enables maximum coverage area of the vascular lumen area, thereby preventing any untreated area within a lumen.

DEVICE AND METHOD FOR PREVENTING STENOSIS AT AN ANASTOMOSIS SITE
20200360126 · 2020-11-19 ·

The present invention relates to treating or preventing stenosis at an anastomosis site. In one embodiment, the present invention is a stent is curved along the longitudinal axis for placement in and adjacent to the graft orifice. In a further embodiment, the stent is drug coated to allow delivery of antivasculoproliferative drugs directly to the vicinity of the graft orifice. In a further embodiment, the stent is expandable by use of an external wire. In another embodiment, the present invention is a kit comprising the specially configured stent together with a sleeve comprising a biocompatible matrix material and a pharmaceutical agent, wherein the sleeve is applied to the external surface of the vessel or graft, resulting in extravascular delivery of a pharmaceutical agent. Methods for treating or preventing stenosis at an anastomosis site by applying the extravascular sleeve and the intravascular stent are also provided.

Medical examination gloves
10792401 · 2020-10-06 ·

The disclosed medical examination glove comprises natural or nitrile rubber latex, and a water soluble singlet oxygen generator. The glove can be manufactured by contacting a glove former with a coagulant solution comprising divalent calcium cations and carbonate particles and a water soluble singlet oxygen generator and then contacting the glove former with a natural or nitrile rubber latex dispersion.

MESH IMPLANT FOR USE IN BREAST RECONSTRUCTION
20200268945 · 2020-08-27 · ·

A resorbable polymeric mesh implant whose implant configuration varies over time after implantation for use in breast reconstruction, wherein the resorbable polymeric mesh implant comprises at least a first material and a last-degraded material, wherein the last-degraded material is substantially degraded at a later point in time in the body than the first material. The modulus of elasticity of the last-degraded material is significantly lower than the modulus of elasticity of the first material. The last-degraded material has a modulus of elasticity that corresponds to an elongation of 18 to 32% when subjected to a tensile load of 16 N/cm. The resorbable polymeric mesh implant is tubular and configured to retain a breast implant.
