An adhesion barrier is comprised of, consists of, or consists essentially of a sheet having a top surface and a bottom surface. The sheet includes either (i) interconnected links or (ii) interconnected, vertically aligned, partitions. The links form pores or the partitions form pores, with the pores extending from the top surface through the bottom surface. The sheet is comprised of, consists of, or consists essentially of a flexible or elastic polymer.

The invention consists of an expansion catheter for intrauterine placement, featuring anatomical characteristics adaptable to the different morphologies of the uterine organ in its internal cavities, and which efficiently enables the dilatation and separation of the internal walls of the cavity subsequent to their reduction in the surgical process of endometrial scraping in the different surgical techniques of the procedure, in order to serve as a separator and isolator in the prevention of intrauterine adhesions, facilitating drainage both internally through the device and perimetrally. The device, containing an expansion device in a collapsed state, is placed in the uterus by means of an insertion device with the aid of a pusher, which is discarded together with the insertion device once the unit is in place.

An adhesion-preventing material having a high adhesion-preventing effect has been demanded. 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.

An enclosure provides a prophylactic barrier that may be permeable to gases, hormones, proteins, and peritoneal fluid, but restrains tumor cells within the enclosure so as to inhibit ovarian cancer invasion of adjacent tissue, and increase the speed of diagnosis of ovarian dysplasia, including cancer. The enclosure includes one or more of fiducial markers, heat sensors, and blood flow reflectors, which may be imaged non-invasively in order to detect conditions or pathology affecting the ovary. The enclosure may also include an access port that permits sampling of the enclosure's contents to further aid in detecting or treating conditions or pathology affecting the ovary.

Methods and devices for treatment of a uterine cavity to prevent adhesions following a surgical intervention.

A device and a method for delivering a solution to tissues and/or organs. The solution contains at least one solvent and at least one solute. The device includes at least one chamber which contains sodium 2-mercaptoethanesulfonate in powder form. The method includes the steps of dissolving the solute in the solvent inside the device. The resulting solution is delivered immediately to tissues and/or organs to facilitate dissection.

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.

A support assembly for supporting a biological product (e.g., membrane) in an operative position. The support assembly has a base and a cover. A membrane receiving portion of the base defines a plurality of perforations that extend between top and bottom surfaces of the product receiving portion. The cover is releasably coupled to the base in a product-covering position in which the cover overlies the product receiving portion of the base. In the operative position, the biological product engages the top surface of the product receiving portion and the bottom surface of the cover.

A device and a method for delivering a solution to tissues and/or organs. The solution contains at least one solvent and at least one solute. The device includes at least one chamber which contains sodium 2-mercaptoethanesulfonate (Mesna) in powder form. The method includes dissolving the solute in the solvent inside the device. The resulting solution is delivered immediately to tissues and/or organs to facilitate dissection. A composition including Mesna and one or more dye which is used in a method of surgery, a kit including Mesna, and a method for visualization of a composition including Mesna which is applied to tissues. A method for producing a composition including Mesna for use in a method of surgery, a kit for obtaining a composition including Mesna for use in a method of surgery, a device for chemically assisted tissue dissection facilitated by Mesna, and a method of surgery using Mesna.
