Abstract: A vacuum therapy device for treatment of a defect internal of a human or animal body, the device comprising: a suction tube extending from: (i) a proximal portion for coupling to a source of negative pressure outside the body, to (ii) a distal portion for providing suction proximal to the defect when inserted into the body; a porous medium coupled to the distal portion of the suction tube to provide suction to the defect when inserted into the body for treatment thereof; and a constraining sleeve for selective compression of the porous medium, the constraining sleeve having a proximal end and a distal end, wherein the constraining sleeve is movable relative to the porous medium between: an insertion position in which the proximal and distal ends of the sleeve are arranged at the distal portion of the suction tube so that the sleeve at least partially surrounds the porous medium to retain the porous medium in a compressed state during insertion into the body; and a treatment position in which the porous medium

Abstract: A kit comprising a tissue dressing material for being applied in contact with the tissue of a patient and a detachment solvent for removing the tissue dressing material from the tissue. A method of treating a tissue of a patient, the method comprising the steps of: applying a water-soluble tissue dressing material in contact with the patient's tissue; and applying an acidic detachment solvent to the tissue dressing material for removing the tissue dressing material from the tissue. A method of treating a tissue of a patient, the method comprising the steps of: applying a liquid tissue dressing material in contact with the patient's tissue; and applying a detachment solvent to the tissue dressing material for removing the tissue dressing material from the tissue.

Abstract: A fluid-swellable fiber in particular for the use as a surgical suture, the fiber comprising chitosan, the fiber's swelling ratio being less than 100%, and a fabric comprising the fiber. Moreover, a method of manufacturing from a chitosan-containing solution a fiber comprising chitosan, wherein during manufacture, the solution is brought into contact with a coagulation medium containing at least one organic solvent, a method of removing a fiber from a living organism, wherein the fiber is at least partly dissolved in a solvent applied from the outside, and a kit comprising a chitosan containing fiber and a solvent for at least partly dissolving the fiber.

Abstract: A method for manufacturing a medical product comprising a hollow body (2), wherein at least part of a wall of the hollow body (2) is coated at least on the inside with a layer comprising a polymer; at least the part of at least the inside of the wall of the medical product is brought into contact with a mixture (6) of the polymer and the polymer is deposited from the mixture (6) on at least the part of the inside of the wall. And a medical product comprising a hollow body (2) with a wall consisting of one or more structural elements (16), at least a section of the wall being coated with a layer (15) comprising native chitosan, wherein both on the inside and the outside of the hollow body (2) at least some of the one or more structural elements (16) of the wall of the hollow body (2) are at least partly coated with the native chitosan layer (15). And a method for electrodepositing a polymer on an electrode from an acidic mixture of the polymer, wherein the mixture (6) comprises a multibasic acid.

Abstract: A chitosan for use in an antimicrobial treatment of a patient's tissue and a pharmaceutical composition comprising a chitosan for use in an antimicrobial treatment of a patient's tissue. A method of treating a microbial infection, the method comprising the step of administering to a patient an effective amount of a chitosan and an aqueous solution comprising chitosan. A chitosan or a pharmaceutical composition comprising a chitosan for use in an epithelial cell growth stimulating treatment of a patient's tissue. A method of stimulating the growth of epithelial cells the method comprising the step of administering to a patient or to an epithelial cells containing cell culture an effective amount of a chitosan or a pharmaceutical composition comprising chitosan. A tissue dressing material characterized in that it consists of chitosan or a chitosan comprising composition.

Abstract: A tissue dressing material for being applied in contact with a tissue of a patient. The tissue dressing material's main component is deacetylated native chitosan. Moreover, a liquid tissue dressing material for being applied in contact with a tissue of a patient, the tissue dressing material being an aqueous mixture. The main component of the constituent(s) of the mixture other than water is deacetylated native chitosan.

Abstract: The thoracic catheter has an elongated, integrally formed lead designed to be pulled by the surgeon without the use of a clamp. The lead has sufficient length to allow it to be readily held within the surgeon's hand, or even wrapped around the hand. A tip at the proximal end of the lead is used to guide the lead through the chest wall. In the alternative, the tip may have a trocar that is used to make the secondary incision in the chest wall for the placement of the catheter.
