FILLER HAVING EXCELLENT FILLER PROPERTIES COMPRISING HYALURONIC ACID HYDROGEL

The present invention relates to a filler comprising a hyaluronic acid hydrogel having a lift value in a specific range relative to the unit amount (w/w %) of hyaluronic acid included in a filler, in contrast to the modification degree, and as a result of having said lift value the filler exhibits improved high viscoelasticity flow properties, has the advantages of both monophasic and biphasic hyaluronic acid hydrogel fillers, and thus exhibits good tissue-restoring properties, has low mobility when injected into skin whilst still maintaining the shape thereof for a long time, and has minimized deformation of the hyaluronic acid through the minimization of the use of crosslinkers, and thus the natural form of hyaluronic acid molecules can be maintained, enabling a reduction in the occurrence of immune reactions and side effects, and thus has excellent soft tissue restoration properties, volume expansion properties and wrinkle alleviation properties.

20210393256 · 2021-12-23 ·

Provided are a suture, a suturing apparatus and applications thereof. The suture includes an elongated body, a first cam assembly and a second cam assembly both sleeved on the elongated body. The elongated body includes a first free end and a second free end. The first cam assembly and the second cam assembly each include at least one cam. The small end of the cam of the first cam assembly faces the first free end of the elongated body and the small end of the cam of the second cam assembly faces the second free end of the elongated body. A cross-sectional area of the small end of the cam is less than a cross-sectional area of the large end of the cam. A wall thickness of the cam tapers along a direction from the small end to the large end.

SURGICAL IMPLANTS AND METHODS FOR NIPPLE OR FACIAL RECONSTRUCTION
20210386911 · 2021-12-16 ·

The present disclosure provides surgical implants that are useful for nipple-areola complex (NAC) or facial reconstruction in a subject, and methods for fabricating and using the same. The surgical implants of the present technology comprise minced or zested cartilage that is encaged by an external biocompatible scaffold.

PROSTHESIS FOR IN VIVO INSERTION, COATED WITH CROSS-LINKED POLYPHOSPHORYLCHOLINE

The present invention relates to a coating composition for an in-vivo implantable prosthesis including a photoinitiator, a crosslinking agent, and a phosphorylcholine (pc) monomer having an acrylate group, a method of coating an in-vivo implantable prosthesis using the coating composition, and a cosmetic prosthesis coated with the crosslinked polyphosphorylcholine.

An in-vivo implantable prosthesis coated with crosslinked polyphosphorylcholine may be manufactured by a simple method of applying a coating composition including a photoinitiator, a crosslinking agent, and a phosphorylcholine (pc) monomer having an acrylate group according to the present invention, and then irradiating uv rays. The crosslinked polyphosphorylcholine coating may provide hydrophilicity for the surface and may also remarkably reduce adsorption of proteins and fibroblasts, which may cause side effects such as capsular contracture. Further, the coating has strong enough not to peel off even under stimulation, and therefore, it is maintained under vigorous activity after implantation, thereby being usefully applied to the manufacture of an in-vivo implantable prosthesis with reduced side effects, such as breast prosthesis for cosmetic surgery.

High density fibrous polymers suitable for implant

This invention includes malleable, biodegradable, fibrous compositions for application to a tissue site in order to promote or facilitate new tissue growth. One aspect of this invention is a fibrous component that provides unique mechanical and physical properties. The invention may be created by providing a vessel containing a slurry, said slurry comprising a plurality of natural or synthetic polymer fibers and at least one suspension fluid, wherein the polymer fibers are substantially evenly dispersed and randomly oriented throughout the volume of the suspension fluid; applying a force, e.g., centrifugal, to said vessel containing said slurry, whereupon said force serves to cause said polymer fibers to migrate through the suspension fluid and amass at a furthest extent of the vessel, forming a polymer material, with said polymer material comprising polymer fibers of sufficient length and sufficiently viscous, interlaced, or interlocked to retard dissociation of said polymer fibers.

Anchored implant for a nasal prosthesis
11364113 · 2022-06-21 · ·

There is provided herein a bone anchored implant that is used to support a nasal prosthesis in patients with a missing external nose. The implant consists of central section (which is preferably generally triangular) suspended within the aperture of the nasal cavity by four fixation arms which extend radially to engage the surrounding maxillary bone. The triangular portion may support three fixation points, one at each corner of the triangular portion, which in turn, directly engage the nasal prosthesis either via magnets or mechanical locking interface. Extending radially from the triangular section, the four fixation arms may flatten to a clover leaf arrangement of three apertures which accommodate micro-screws that secure the implant to the surrounding maxillary bone.

Handpieces for tissue treatment

A dermatological skin treatment device is provided. The device comprises a handpiece and a cutting tool, wherein the tool is inserted through the conduit and percutaneously inserted into a tissue disposed within a recessed area of the handpiece. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes.

TISSUE EXPANDER WITH EXTENDED INFLATION MECHANISM USING CONTROLLED CHEMICAL REACTION
20230263612 · 2023-08-24 ·

Embodiments of the present disclosure relate to a tissue expander that expands in a gradual manner using a controlled release of gas resulting from a chemical reaction of a reactant substance within the tissue expander. The reactant substance is initially in a liquid or solid state and is stored in an internal chamber of the tissue expander. The chemical reaction of the reactant substance produces the gas that causes the tissue expander to expand over time. The tissue expander continues to expand gradually after implanting of the tissue expander within a patient’s body and initiating of the chemical reaction.
