Implantable prostheses and related methods are generally described. In some embodiments, the prosthesis may be used for soft tissue reconstruction. The prosthesis may be formed from a three-dimensional load-bearing porous scaffold having interconnected networks of pores, thereby enabling tissue infiltration and allowing native tissue, blood vessels, and cells to colonize on the scaffold. In some embodiments, the scaffold may be formed from a biodegradable material such that it may degrade during the tissue infiltration process, leaving native tissue. In some embodiments, the stent may be formed from a triple periodic minimum surface, such as a helical tetracosahedron, to achieve high compressibility and high porosity. The compressibility of the implant may simulate the mechanical behavior of native tissue and allow the implant to be delivered through a small incision site (e.g., with an implant delivery funnel).

A surgical implant delivery device is provided. The surgical implant delivery device comprises a sleeve. The sleeve includes a delivery portion and an accommodating portion. The delivery portion has an opening. The accommodating portion extending from the delivery portion. The delivery portion includes a wing portion protruding widthwise.

The present invention relates to a lifting thread, a method for manufacturing the lifting thread, and a lifting thread insertion device. The lifting thread is manufactured in a coil spring shape by twisting a medical thread, and then winding (coiling) same around the outer peripheral surface (circumference) of a needle, such that when the lifting thread is tensioned and compressed during a skin lifting procedure, a first elastic force according to the torsional stress of the medical thread, and the greater stress obtained by adding the tensile or compressive stress of the lifting thread to the first elastic force, that is, a second elastic force, are applied so as to maintain, as is, the elasticity of the skin without sagging of the lifted skin even after a long period of time has elapsed after the skin lifting procedure, and thus a lifting effect can be maximized.

The present disclosure relates to a kit. The kit of the present disclosure comprises: a kit body comprising a needle tube and a needle, the first end of the needle being mounted to the needle tube; and a catabolic filling thread comprising a first segment and a second segment connected to each other, at least a part of the first segment being located inside the needle, and at least a part of the second segment being located outside the needle, wherein the catabolic filling thread is a thread made of poly-L-lactic acid. The kit of the present disclosure comprises a catabolic filling thread which can be composed of poly-L-lactic acid, is absorbable, has no residue, and is metabolized into lactic acid in the human body. Such a configuration makes the catabolic filling thread itself not only play a role in filling and tightening when filling surgery is performed using the catabolic filling thread of the present disclosure, but also the lactic acid after its metabolism can still stimulate fibroblasts in the skin and subcutaneous tissue to reconstruct the collagen framework in the human body by using fibroblasts.

Implantable prostheses and related methods are generally described. In some embodiments, the prosthesis (100) may be a generally ellipsoidal (e.g., spherical) shape, formed of one or more subunits (20). The subunits may be conical or frustoconical, formed through manipulation of a two-dimensional substrate material. The sidewalls of the subunits may be fixed to one another to enhance the stiffness of the prosthesis. In some embodiments, markers (30) may be used to help distinguish the prosthesis in the implant site through medical imaging modalities (e.g., x-ray imaging). In this way, the implant site, which may also be the site of a recent biopsy and / or a diseased tissue resection, may readily be identified. The prosthesis may be formed of a porous material to induce tissue infiltration, which may facilitate natural tissue regeneration for more natural look and feel of the tissue. Tissue infiltration may result in the prosthesis having an enhanced resistance to migration following implantation.

Introduced here are novel techniques and tools for augmenting the lips through superficial linear injection of dermal fillers. At a high level, these techniques are representative of a two-step approach to augmentation. In the first stage, an implement that is appropriately positioned inside a lip can be moved sideways—an action referred to as a “side push.” In the second stage, dermal filler can be ejected from the implement so as to fill the resulting void. These techniques can be used by healthcare professionals to reshape the lips for medical or aesthetic purposes. These techniques were developed in an attempt to permit augmentation of the outer surface of a lip so as to increase its volume by expanding sideways while turning the lip outward. Presented here are also tools to improve the accuracy of injection. With these techniques, the desired result-namely, a plumper lip—may be readily and consistently achievable.

The invention relates to a hydrogel product comprising glycosaminoglycan molecules as the swellable polymer, wherein the glycosaminoglycan molecules are covalently crosslinked via crosslinks comprising a spacer group selected from the group consisting of di-, tri-, tetra-, and oligosaccharides.

The application of unilateral or bilateral permanent prostheses to the labium majus in the external genitalia of women for reconstructive and aesthetic purposes may make it appear fuller. The labium majus may lose its fullness and symmetry due to menopause, rapid weight gain and loss, traumas, cancers, and infectious diseases. Aesthetic interventions (e.g., hyaluronic acid filler injection and fat grafting) aiming to provide the labium majus with fullness have become very popular in recent years. The hyaluronic acid filler is used for reconstructive purposes to achieve fullness in labium majus. However, the maximum amount that can be injected is 3 mL, which is often insufficient for the desired outcome and its effect lasts for a maximum of 1 year. Autologous fat grafting is administered by taking 18–120 mL of fat from patients themselves; however, its effect usually lasts 1 to 4 years. The application of a prosthesis will provide labium majus with fullness and this effect will be long-lasting. The outer edge of the prosthesis is convex and the inner edge is concave. In male genitalia, prostheses have been used since 1950 to provide the testicles with fullness. Scientific studies have shown that these prostheses positively affect self-confidence and body perception indices in men.

The implant (200) comprises a plurality of unit cells (102) arranged to form a three-dimensional grid structure, the three-dimensional structure having an idle volume of the implant. The plurality of unit cells are arranged to form a porous network of a three-dimensional structure (101) wherein the three-dimensional structure is a reversibly compressible three-dimensional structure, and wherein the overall porosity of the three-dimensional structure of the implant is at least 50%.

This invention relates to a lifting thread, a method for manufacturing the lifting thread, and a lifting thread insertion machine. By twisting a medical thread and then winding it around the outer surface of a needle to produce a lifting thread in the form of a coil spring, when the lifting thread is pulled or compressed during the skin lifting procedure, a first elastic force due to the torsional stress of the medical thread and an even larger stress, i.e., a second elastic force, which is the sum of the torsional stress of the medical thread and the tensile or compressive stress of the lifting thread, are acted upon it. This configuration makes it possible to maximize the lifting effect by maintaining the elasticity of the skin without any sagging of the treated skin even after a long period of time has passed since the skin lifting procedure.

The compressibility of the implant may mimic the mechanical behavior of natural tissue, and allow the implant to be delivered through a small incision site (e.g., with an implant delivery funnel).
