MEDICAL IMPLANT SURFACE-MODIFIED WITH FUNCTIONAL POLYPEPTIDE

Provided is a medical implant including: an implant base having a surface made of a silicon material; a linker having one end attached onto the surface of the implant base; and a cytokine bound to another end of the linker. By inducing the secretion of anti-inflammatory cytokines, a capsular contracture, which is one of the complications that may occur after transplantation of the patient's breast implant, may occur less.

SYSTEM AND METHOD FOR IMPLANT PRODUCTION
20220202560 · 2022-06-30 ·

Disclosed herein is a multi-modal imaging methodology for creating patient-specific three-dimensional images of a breast volume, for use in the production of breast implants. In one aspect, a surface imaging technique may be used to create a three-dimensional model of an external shape of a patient, such as the external morphology of a breast. In one aspect, an internal imaging technique may be used to create a three-dimensional model of the internal shape of the thorax underneath the breast. The external and internal models may then be referenced to one another and a unified model may be created to generate a reliable, personalized model of breast volume.

SCAFFOLDS FOR USE IN TISSUE ENGINEERING AND METHOD FOR PREPARING SCAFFOLDS
20220184276 · 2022-06-16 ·

The present disclosure is directed to a degradable 3D-printable scaffold for use in tissue engineering, which scaffold has a combined gradient and staggered structure. Further provided is a medical device for use in tissue engineering, comprising such a scaffold. The present disclosure also provides a method for preparing a scaffold by additive manufacturing, e.g. 3D-printing, a method for in vivo tissue engineering, use of the scaffold in an in vitro cell culture system, in an in vitro method for culturing of cells and/or in an in vitro method for regenerating tissue. Also provided is a scaffold and a medical device for use in a method for in vivo tissue engineering. Further disclosed is a novel degradable copolymer of ε-caprolactone and p-dioxanone, which can be printed without degradation and which is particularly suitable for use as scaffold material in the scaffold and method according to the present disclosure.

Methods for tissue passivation

One aspect of the invention provides a method of preventing or reducing stenosis in a subject. The method includes implanting a passivated graft comprising vein into an artery. The implanting of the graft replaces and/or bypasses a diseased segment of the artery. The passivated graft including vein is prepared by exposing the exterior surface of the passivated graft comprising vein to a tissue structure stabilizing agent (“TSSA”) under conditions sufficient to promote cross-linking of proteins within the vein.

Fiber-hydrogel composite surgical meshes for tissue repair

The presently disclosed composition and methods are provided for a hydrogel or nanofiber-hydrogel composite integrated with a surgical scaffold or mesh. A surgical scaffold device comprised of laminar composite is disclosed for the purpose of reducing foreign body response, managing tissue-materials interface, and improving the integration of the surgical mesh with the surrounding tissue of a subject.

SOFT TISSUE SUPPORTS, AND METHODS OF MAKING AND USING SAME

Soft tissue supports, soft tissue implants, and methods of making and using soft tissue supports are disclosed. One soft tissue support includes a unitary piece of processed porous tissue material having an anterior portion and a posterior portion. The anterior and posterior portions define a cavity therebetween. The cavity is sized to receive a breast implant therein. The cavity has at least one opening sized to receive the breast implant therethrough. One soft tissue implant includes the soft tissue support and a breast implant positioned within the cavity of the soft tissue support. The implant may further include a soft tissue graft configured to support the processed porous tissue material and the breast implant. A method of using a soft tissue support includes inserting a breast implant into the soft tissue support, and implanting the soft tissue support containing the breast implant in the cavity.

20220142762 · 2022-05-12 · ·

An implant material having an implant surface comprising a plurality of tissue-contacting members arranged in a regular or irregular two-dimensional array, each tissue-contacting member having a convex curved tissue-contacting surface. Methods of preparing and using such implant materials.

Hydrogel devices and methods of making and use thereof

Disclosed herein are hydrogel devices and methods of making an use thereof. The devices can comprise: a continuous hydrogel matrix; a first chamber in the hydrogel matrix; and a second chamber in the hydrogel matrix; wherein the first chamber and the second chamber are each independently perfusable; wherein the first chamber is fluidly independent from the second chamber; wherein the first chamber is configured to be at least partially filled with adipose tissue; wherein the second chamber is configured to be at least partially filled with an oxygenated fluid; wherein the first chamber is defined by a first border; wherein the second chamber is defined by a second border; and wherein the first chamber and the second chamber are spaced apart from each other by an average distance of from 50 micrometers (microns, μm) to 800 μm as measured from the first border to the second border.

Method for producing shell and foam filler for a breast implant

A method for manufacturing a breast implant includes producing a silicone shell of the breast implant by rotating a mold containing a silicone material to evenly spread the silicone material over an inner surface of the mold. Subsequently, an elastic filler material including silicone foam is formed in the shell by (i) injecting into the mold a mixture comprising silicone gel and gas bubbles and (ii) rotating the mold to homogenize the mixture.
