SYSTEMS FOR DRYING SHEETS OF DONOR-PROVIDED HUMAN TISSUE
20180000986 · 2018-01-04 ·

Embodiments of this technology may include an apparatus for drying tissue. The apparatus may include human donor tissue placed in contact with and between at least two layers of backing material. This tissue and backing layer may then be restrained by two plates. This tissue may be amniotic tissue. The backing layer may include woven or nonwoven material. This backing layer may be wetted with a saline solution. At least one of the plates of the tissue drying apparatus may be perforated. The tissue assembly along with the plates may then be placed inside a chamber configured to receive the plates and tissue assembly. The chamber may be configured so that gas can be forced into the chamber with the gas flow going around the plates and the tissue assembly.

TISSUE MATRICES INCORPORATING MULTIPLE TISSUE TYPES

The present disclosure provides tissue products produced from extracellular tissue matrices. The tissue products can include acellular extracellular matrices including combinations of different tissue types. The combination can harness various properties of the different tissues to provide improved composite structures with desired mechanical and/or biologic properties.

SIZE ADJUSTABLE DEVICE TO COVER AND SECURE IMPLANTABLE DEVICES IN SURGICAL APPLICATIONS
20230233308 · 2023-07-27 · ·

A size adjustable cover used for soft tissue reinforcement which is adapted to envelop an implantable device, such as a breast implant, in a surgical application. The cover is formed using a circular two-dimensional implantable matrix material having an inner circle and a plurality of fringes which radiate circumferentially from the inner circle. The implantable device is positioned upon the inner circle, and the plurality of fringes are folded inwardly to form an overlapping implant pocket which envelops the implantable device. Each fringe further has a punched opening, allowing a loop of suture thread to link each fringe together. Certain fringes are excluded from the loop to create stabilization tabs which radiate from the inner circle and are attached to a site of host implantation to stabilize the cover and the implantable device within.

Ear tissue scaffold implant for auricular tissue reconstruction

Ear implants for auricular tissue reconstruction in a patient are provided. The ear implant may be a tissue scaffold multicomponent assembly for reconstruction of auricular tissue. Thus, the assembly may include both a first and a second tissue scaffold component. Each comprises a biocompatible polymeric material having a plurality of open pores configured to support cell growth. The first tissue scaffold component defines a central void region and at least a portion of an outer ear framework of the patient after implantation. The second tissue scaffold component defines a base portion. After implantation into the patient, the second tissue scaffold component seats within the central void region of the first tissue scaffold component, so that the second tissue scaffold component is secured to the first tissue scaffold component. Methods for reconstructing auricular tissue in a patient using such ear implant tissue scaffolds are also provided.

Systems, instruments, methods, and compositions are described involving removing a portion of the epidermis within a donor site on a subject, and harvesting dermal plugs within the donor site. An injectable filler is formed by mincing the dermal plugs. The injectable filler is configured for injecting into a recipient site on the subject.

EXTRACELLULAR MATRIX STRUCTURES
20230026971 · 2023-01-26 · ·

A sheet structure comprising two joined extracellular matrix (ECM) tissue or sheet layers and a physiological sensor disposed therebetween; the ECM tissue being derived from a mammalian tissue source that includes small intestine submucosa (SIS), urinary bladder submucosa (UBS), stomach submucosa (SS), urinary basement membrane (UBM), liver basement membrane (LBM), amniotic membrane, mesothelial tissue, placental tissue and cardiac tissue.

NATURAL TISSUE SCAFFOLDS AS TISSUE FILLERS
20230016722 · 2023-01-19 ·

Tissue fillers derived from decellularized tissues are provided. The tissue fillers can include acellular tissue matrices that have reduced inflammatory responses when implanted in a body. Also provided are methods of making and therapeutic uses for the tissue fillers.

ATRAUMATICALLY FORMED TISSUE COMPOSITIONS, DEVICES AND METHODS OF PREPARATION AND TREATMENT

A process and system provides for atraumatic preparation of morselized Tissue Particles (TP)s, such as Full Thickness Skin Graft Particles (FTSGPs), cartilage particles and other organ tissue particles, in a liquid medium. The resultant tissue product may be a suspension of Tissue Particles in an aqueous solution and containing highly viable cells and may be rapidly prepared at bedside or in the operating room and conveniently delivered to a patient through a syringe or similar applicator. The morselized Tissues Particles may be used for surgical applications including wound healing, cosmetic surgery, and orthopedic cartilage repairs.
