    摘要: A hydrogel is obtained by combining acrylamide and methylene bis-acrylamide, radical initiation and washing with pyrogen-free water or saline solution to give less than 3.5% by weight polyacrylamide, based on the total weight of the hydrogel. The hydrogel may be used as a soft tissue filler endoprosthesis. Also disclosed is a method of filling a soft tissue in a mammal using the endoprosthesis, and a prosthetic device comprising the polyacrylamide hydrogel.

    摘要: A sheath device (1) suitable for endoscopic instruments (2) and comprising an elongated tubular member (4) having a proximal end (6), a distal open end (7), and at least one fluid channel (23). A flushing unit (5) is connected to the proximal end (6) of the tubular member (4) and comprises a proximal open end (8) suitable for receiving a first endoscopic instrument (2), a fluid inlet (16) in contact with said fluid channel (23), and a fluid outlet (17). The tubular member and the flushing unit together define a first interior guiding passage (10) for sheathing at least a part of said first endoscopic instrument (2). The connection between the tubular member (4) and the flushing unit (5) allows for axial rotation of the tubular member (4) in relation to the flushing unit (5).

    摘要: A biocompatible hydrogel comprises a specified content of polyacrylamide and pyrogen-free water. Also disclosed is a method of making the hydrogel and an injectable or implantable endoprosthesis. The hydrogel may also be used to treat a cosmetic or functional defect. Hydrogels specified according to their polyacrylamide content may be used for medical indications, such as an implantable or injectable endoprostheses for mammoplastic reconstruction, implantable or injectable endoprostheses for treating (reflux) oesophagitis, and for body contouring of various body parts.
