MAGNETIC JOINT IMPLANT
20180000591 · 2018-01-04 ·

The application is directed to devices and methods where one or more magnetic or magnetizable implants provides therapeutic benefits to a patient. The implant may be useful for expanding the range of motion of joints or dynamically providing different responses to changing conditions in the body where the implant is placed. An electromagnet is placed on or in a bone on one side of a joint, and another electromagnet or magnetically active material is placed on or in a bone on the opposing side of the joint. The electromagnet may be continuously energized to relieve pressure in the joint space, or may be energized in response to forces applied to the joint.

Implant for medical use intended to clip to a biological protuberance
11627974 · 2023-04-18 · ·

Disclosed is an implant intended to be introduced into a human or animal body cavity, and includes two walls intended to grip between them a biological protuberance present in the cavity in order to attach the implant to the biological protuberance. Each wall includes a structural element having corrugations such that the structural element is folded up on itself several times, enabling the wall to be folded up before the introduction of the implant, then deployed inside the cavity.

Adhesion-preventing composition

[Problem] An adhesion-preventing material having a high adhesion-preventing effect has been demanded. [Solution] An adhesion-preventing material including a sterilized biocompatible sponge-like laminate, wherein the sponge-like laminate comprises a sponge-like first layer and a sponge-like second layer each of which is at least partially crosslinked with a curing agent and comprises a low-endotoxin alginic acid monovalent metal salt, the alginic acid monovalent metal salt in the first layer has a weight average molecular weight of 10,000 to 2,000,000, the alginic acid monovalent metal salt in the second layer has a weight average molecular weight of 1,000 to 1,000,000, the weight average molecular weights are measured by a GPC-MALS method after a decrosslinking treatment, and the weight average molecular weight of the alginic acid monovalent metal salt in the first layer is higher than that in the second layer.

Absorbable permeability-modulated barrier composites and applications thereof
11197950 · 2021-12-14 · ·

Absorbable barrier composites are designed for modulated gas and water permeability depending on clinical use and are formed of at least two physicochemically distinct components, one of which is a film adjoined to a knitted mesh and/or electrostatically spun, non-woven fabric. Depending on the physicochemical properties of the barrier composite, it can be used in neurological and urinogenital surgical procedures as well as tissue engineering and/or as physical barriers to prevent adhesion formation following several types of surgical procedures.

Placental tissue grafts modified with a cross-linking agent and methods of making and using the same

Described herein are tissue grafts derived from the placenta that possess good adhesion to biological tissues and are useful in wound healing applications. In one aspect, the tissue graft includes (1) two or more layers of amnion, wherein at least one layer of amnion is cross-linked, (2) two or more layers of chorion, wherein at least one layer of chorion is cross-linked, or (3) one or more layers of amnion and chorion, wherein at least one layer of amnion and/or chorion is cross-linked. In another aspect, the grafts are composed of amnion and chorion cross-linked with one another. In a further aspect, the grafts have one or more layers sandwiched between the amnion and chorion membranes. The amnion and/or the chorion are treated with a cross-linking agent prior to the formation of the graft. The presence of the cross-linking agent present on the graft also enhances adhesion to the biological tissue of interest. Also described herein are methods for making and using the tissue grafts.
