TISSUE INTEGRATED DRUG DELIVERY SYSTEM

Infusion sets for subcutaneous drug delivery are described herein. The infusion set integrates a bijel-templated material (BTM) into a cannula such that a portion of the BTM protrudes from the cannula tip into the host tissue. The BTM is a porous, polymeric sponge having a co-continuous architecture with consistent curvature throughout non-constricting, interpenetrating channels, which is critical in mitigation of the deleterious host tissue response, vascularization, and flow redistribution in the implant.

CELL ENCAPSULATION MEMBRANES, DEVICES AND METHODS

The cell encapsulation membrane can include a mesh substrate. The mesh substrate can include a first series of fibers extending in a first direction and a second series of fibers extending in a second direction, the first series of fibers intersecting with the second series of fibers, the mesh substrate defining a plurality of apertures disposed between adjacent fibers of the first series and the second series. The cell encapsulation membrane can further include a coating disposed on the mesh substrate, the coating partially occluding the plurality of apertures defined by the mesh substrate and forming pores. Other embodiments are also included herein.

A METHOD OF MANUFACTURING A DENTAL IMPLANT USING A COMPOSITE NANOCOATING

This invention relates to the field of medical technology, and can be used in dentistry and traumatology, in particular when creating dental implants. Namely, the invention relates to the development and creation of a method for producing a dental implant characterized by high strength, as well as increased ability to activate the process of osteogenesis and osseointegration. The implant obtained by this method is characterized by high biocompatibility, bactericidal properties (reduces pronounced dystrophic and necrotic processes of living tissue), and an increased level of implant surface strength.

MOLDED ARTICLE AND HOLLOW TUBE

A coating film is provided in a cable, a medical hollow tube, a molded article and a hollow tube. The coating film is formed from a rubber composition including a rubber component and fine particles. A static friction coefficient on a surface of the coating film is 0.5 or less. When the coating film is subjected to a testing such that a long fiber non-woven fabric including cotton linters including an alcohol for disinfection with a length of 50 mm along a wiping direction is brought contiguous to the surface of the coating film at a shearing stress of 2×10.sup.−3 MPa to 4×10.sup.−3 MPa, followed by wiping off the surface of the coating film at a speed of 80 times/min to 120 times/min and 20,000 repetitions thereof for a wiping direction length of 150 mm, a difference (an absolute value of a difference) between the static friction coefficients of the coating film before and after the testing is not greater than 0.1.

HEMOSTATIC DEVICES
20210178011 · 2021-06-17 ·

Hemostatic devices for promoting blood clotting can include a substrate (e.g., gauze, textile, sponge, sponge matrix, one or more fibers, etc.), a hemostatic material disposed thereon such as kaolin clay, and a binder material such as crosslinked calcium alginate with a high guluronate monomer molar percentage disposed on the substrate to substantially retain the hemostatic material material. When the device is used to treat a bleeding wound, at least a portion of the clay material comes into contact with blood to accelerate clotting. Moreover, when exposed to blood, the binder has low solubility and retains a majority of the clay material on the gauze. A bandage that can be applied to a bleeding wound to promote blood clotting includes a flexible substrate and a gauze substrate mounted thereon.

Medical device

The invention relates to an implantable medical device having a body comprising a composite material. The body has a variable cross section along a length, a first portion which forms a part of a surface of said body, and a packing portion. An insert is provided in the packing portion for providing an increased thickness to at least a part of the body.

Methods of using water-soluble inorganic compounds for implants

A method for controlling generation of biologically desirable voids in a composition placed in proximity to bone or other tissue in a patient by selecting at least one water-soluble inorganic material having a desired particle size and solubility, and mixing the water-soluble inorganic material with at least one poorly-water-soluble or biodegradable matrix material. The matrix material, after it is mixed with the water-soluble inorganic material, is placed into the patient in proximity to tissue so that the water-soluble inorganic material dissolves at a predetermined rate to generate biologically desirable voids in the matrix material into which bone or other tissue can then grow.

Reinforced tissue graft

A biocompatible tissue graft includes a first layer of a bioremodelable collageneous material, a second layer of biocompatible synthetic or natural remodelable or substantially remodelable material attached to the first layer; and at least one fiber that is stitched in a reinforcing pattern in the first layer and/or second layer to mitigate tearing and/or improve fixation retention of the graft, and substantially maintain the improved properties while one or more of the layers is remodeling.
