COMPOSITE SCAFFOLD FOR THE REPAIR, RECONSTRUCTION, AND REGENERATION OF SOFT TISSUES

The disclosed composite scaffold provides a highly porous and flexible structure that substantially maintains its three-dimensional shape under tension and provides mechanical reinforcement of the repair or reconstruction-first via scaffold mechanical properties, and subsequently, through newly regenerated functional tissue as the scaffold is resorbed.

SYNTHETIC IMPLANT DEVICE REPLICATING NATURAL TISSUE STRUCTURE AND METHODS OF MAKING SAME

A composite implant device for use in a medical application, comprising a synthetically-derived mesh that mimics particular critical aspects of a biologically-derived mesh. The composite implant device can be used for the reinforcement and reconstruction of tissues within the body and can be comprised of a majority of synthetic components and minority of naturally-derived components which mimic the structure and function of a naturally-derived mesh.

Nasal implants and systems and method of use

Described are implants for placing in a body, tools for delivering the implants, and systems and methods for using implants and tools for placing in a body and more particularly to nasal implants, tools for delivering nasal implants, and systems and methods for using such implants and tools. A tool may include a hand-held implant delivery device that holds, moves, orients, inserts, or shapes an implant. An implant may be a biodegradable, longitudinal implant that may be oriented for implantation by an implant delivery device.

MEDICAL DEVICES TO LIMIT MOVEMENT OF BREAST IMPLANTS

Breast fixation devices for use in breast reconstruction and breast augmentation limit the rotation or movement of breast implants after implantation that results in an unnatural appearance of the breast. The breast fixation devices can include a thin-walled enclosure in the shape of a pouch. A breast implant is secured inside the pouch to limit movement by applying compression to the breast implants, or using a mating or interlocking mechanism between the pouch and breast implant. The pouches containing the breast implants are implanted in the breast. Tissue in-growth into the pouch limits movement of the pouch-breast implant assembly and thereby limits rotation, migration, and displacement of the breast implant. The pouches preferably comprise poly-4-hydroxybutyrate or copolymer thereof.

Stents for Prosthetic Heart Valves

A stented valve including a generally tubular stent structure that has a longitudinal axis, first and second opposite ends, a plurality of commissure support structures spaced from the first and second ends and extending generally parallel to the longitudinal axis, at least one structural wire positioned between each two adjacent commissure support structures, and at least one wing portion extending from two adjacent commissure support structures and toward one of the first and second ends of the stent structure. The stented valve further includes a valve structure attached within the generally tubular stent structure to the commissure support structures.

Drug-releasing biodegradable stent

The present invention relates to a drug-releasing biodegradable stent. The drug-releasing biodegradable stent includes: a first stent structure configured to have a plurality of cells by means of the wire crossing pattern of a woven structure and be provided in a hollow cylindrical shape by weaving a metal wire made of a shape-memory alloy in a specific pattern on a jig; and a second stent structure formed as a 3D print that is provided to have a plurality of cells by means of the wire crossing pattern of a printed structure and also have a hollow cylindrical shape by performing 3D printing using a printing material including a biodegradable polymer and a drug, and disposed such that it covers the outer circumferential surface of the first stent structure or the outer circumferential surface thereof is covered with the first stent structure.

SOFT TISSUE IMPLANT POCKET
20210069374 · 2021-03-11 ·

There is provided a soft tissue implant pocket which reduces the incidence of capsular contracture. The pocket is manufactured from a biodegradable, biocompatible polyurethane foam. The polyurethane contains biodegradable polyols and the foam has a pore size configured for cellular infiltration. The soft tissue implant pocket find use in, for example, breast augmentation and reconstruction.

THE KIRIGAMI MODIFICATION OF BIOMEDICAL TISSUE REINFORCING MESHES AND MATRICES FOR EXPANSILE TWO-TO-THREE DIMENSIONAL CONVERSION

Provided are intraoperative devices, the devices comprising a substrate having a plurality of discontinuous cuts formed therein, the plurality of discontinuous cuts being formed such that when the substrate is subjected to deformation, the substrate is capable of deformation beyond an initial state so as to achieve a first shaped three-dimensional state. Through design of the cut patterns in 2D, one can locally control the stretchability and elasticity within the substrate. The substrate can then be deformed into a 3D structure that can provide shape and support to reconstructed tissue in the desired regions while also minimizing operative time and cost. Also provided are related methods of using the disclosed devices; the devices can be used in autologous tissue donation procedures as well as prosthetic procedures.

Graft material having selectively advanced permeability structure and method

A laser is used to form openings within a graft material to selectively enhance permeability of a prosthesis for tissue integration therein. A feature of utilizing a laser to create the openings for tissue integration builds from its tunability. More particularly, the laser precisely places openings in any pattern and location, and on any textile that forms the graft material. Further, the power and focus of the laser is precisely adjusted to control the diameter and shape of the openings. All parameters of the openings can be controlled at will, allowing for the opportunity to selectively enhance and optimize the permeability of the graft material in a vessel.

Variable permeability layered structure and method

The techniques of this disclosure generally relate to a variable permeability layered prosthesis including an impermeable outer layer and a permeable inner layer. The impermeable outer layer is well suited to seal a dissection opening of a dissection. The permeable inner layer allows fluid to enter into a dead space between the impermeable outer layer and the permeable inner layer. The fluid in the dead space coagulates in the dead space providing a media for tissue growth into the prosthesis. The ability of tissue to integrate into the prosthesis provides biological fixation of the prosthesis in vessels and prevents endoleaks and migration of the prosthesis.
