Abstract: An antianginal composition in the form of a plate is provided for treating ischemic heart disease and is comprised of a biologically soluble and resolvable film and an antianginal coronary vasodilating nitrate. This film is placed buccally on the gum or mouth mucosa for rapid arresting or prevention of angina pectoris attacks.The antianginal film is in the form of a plate, 0.1 to 1.5 mm thick, consisting of a biologically soluble and resolvable carrier. Preferably, the film is comprised of a homoploymer of acrylamide or vinylpyrrolidone, or a copolymer thereof with acrylate, containing from 99 to 70 percent by weight of acrylamide with vinylpyrrolidone and from 1 to 30 percent by weight of acrylate having a molecular mass from 50,000 to 1,000,000, and the active principle having antianginal action, the components being taken in the following proportions, in percent by weight:______________________________________ active substance having 3.0-30.0 antianginal action biologically soluble and 70.0-97.

Abstract: The sutural material consists of a base from a bio-resolvable polymer and a layer of a copolymer of N-vinylpyrrolidone with an alkylacrylate and/or an alkylmethacrylate deposited onto the base and containing an antimicrobal preparation or a mixture of preparations and having the period of its biodestruction shorter than that of the base, the thickness of this layer being equal to 0.1 to 1.0 of the base thickness.

Abstract: A surgical wound retractor including two diverging branches made up of a stationary part and a movable working part hinged thereto. The working parts of both branches have one common guide which embraces them and is rigidly secured on central rods installed on the stationary parts of the branches, while a movable rod disposed between the stationary parts of the branches has one end connected to the diverging device and the other end to the drive of the diverging device.

Abstract: A holder of a valve prosthesis implantable in a patient's circulatory system, including arms which have handles at one of their ends, and three or more working jaws provided at the end thereof for a valve prosthesis to secure thereon. The ends of all the working jaws form a circle when brought apart.

Abstract: An aortic cannula, including a head which has a front end adapted for being inserted into the aorta, and a base communicating with a blood supply tube; the head is shaped as an oblate cone that flares out from the front end which is an ellipse in cross-section, towards the base which is a circle in cross-section, while the tube is provided with a plurality of through holes or perforations located in an immediate vicinity of the place where it is joined with the base, and has a slidable sleeve adapted to operatively cover the perforations.

Abstract: A pharmaceutical preparation for the treatment of diabetes mellitus comprising the following components, in percent by weight:______________________________________ crystalline insulin with a conventional 1 to 25.0 activity of 1 mg = 20 units additives inhibiting deactivation of insulin, 0.02 to 10.0 viz. 5-(para-[N--(3-methoxypyridazinyl-6)- sulphamido]-phenylazo)-salicylic acid, calcium gluconate or a mixture thereof preservatives 0.1 to 15.0 additives adjusting solubility of 0.01 to 10.0 insulin water-soluble polymeric base the balance.

Abstract: An instrument comprising a tubular staple case is disclosed, the case being traversed by a supporting rod extending outwardly therefrom with its front end. The tubular case is used to mount a plunger with a knife arranged on the rod. An abutment head mounted on the front end of the rod is made generally longitudinally detachable consisting of two members, an internal member detachably mounted on the front end of the rod and an external member encompassing the internal member and made up of interdetachable rests. Moreover, provision is made for a staple magazine and a female die with grooves for bending staples as well as a drive imparting motion to the plunger and a mechanism for adjusting the gap between an end of the case and an end of the head.

Abstract: The device for administering medicinal preparations comprises an isolated capsule subdivided into a chamber for a first medicinal preparation and a chamber for a second medicinal preparation. Coaxially inside said isolated capsule concentrically therewith is the piston which bounds said chamber for the first medicinal preparation. Made fast on said piston is the injection needle having the hole located at the base of said piston. Provision is made in the device for a mechanical actuator of said piston, which is a spring-opposed pushrod located inside the housing which also accommodates the retaining member for said spring-opposed pushrod. Said chamber for the second medicinal preparation is arranged concentrically with said chamber for the first medicinal preparation so as to embrace the latter. Said isolated capsule is mounted traversably inside said housing, while communication between both of said chambers is established upon a positive extension of said isolated capsule from said housing outwards.
