Patent number: 5387247Abstract: A prosthetic device which includes a biocompatible carbon film firmly adherent to a substrate. The carbon preferably is turbostratic and is preferably very thin, e.g., less than about one micron. The thin carbon biocompatible film is dense and covers at least that portion of the substrate which will be in contact with body tissue and/or fluids to insure against physiological rejection and degradation of the prosthetic device. The carbon can be deposited on a variety of substrates, including low temperature substrates, in situ, without adversely affecting the mechanical properties of the substrate. The prosthetic device of the invention is formed by triode sputtering vacuum deposition at a relatively low temperature to achieve the desired results with respect to the deposited carbon and the substrate and with respect to the required adherence therebetween.Type: GrantFiled: January 3, 1990Date of Patent: February 7, 1995Assignee: Sorin Biomedia S.p.A.Inventors: Franco Vallana, Pietro Arru

Patent number: 4758151Abstract: A vacuum forming apparatus for fixing and shaping animal tissue into the shape of a cardiac valve prosthesis, including a tapered form, with elongated through apertures, suspended in a reservoir of fixative and vacuum means for producing a reduced pressure within the tapered form.Type: GrantFiled: June 6, 1986Date of Patent: July 19, 1988Assignee: Sorin Biomedics S.p.A.Inventors: Pietro Arru, Gioacchino Bona, Maria Curcio, Franco Vallana

Patent number: 4624822Abstract: Sheets of incompletely fixed biological tissue comprising portions for defining valve flaps of a cardiac valve prosthesis are mounted on forming means which can separate in a substantially fluid-tight manner the opposite faces of such portions. These opposite faces are subjected to a fluid pressure difference which produces deformation of the portions towards a conformation substantially identical with the conformation of the valve flaps when mounted in the prosthesis. The biological tissue is finally fixed while the portions defining the valve flaps of the prosthesis are maintained in the said conformation. The sheets of biological tissue are then separated from the forming means to be subsequently mounted in the frame of the prosthesis.Type: GrantFiled: July 25, 1984Date of Patent: November 25, 1986Assignee: Sorin Biomedica S.p.A.Inventors: Pietro Arru, Gioacchino Bona, Maria Curcio, Franco Vallana

Patent number: 4495039Abstract: A pyrocarbon tip for a cardiac stimulator electrode is subjected to an anodic electrolytic treatment in which a strong, concentrated acid with oxidizing properties, or a mixture of two or more such acids, is used as the electrolyte. The treatment is carried out with a voltage greater than 1 V, preferably between 1 and 20 V, and with a current density greater than 3 mA/mm.sup.2, preferably between 30 and 40 mA/mm.sup.2. Pyrocarbon tips treated in this manner have very low bias voltages in use.Type: GrantFiled: August 6, 1982Date of Patent: January 22, 1985Assignee: Sorin Biomedica S.p.A.Inventors: Osvaldo Cerise, Pietro Arru, Franco Vallana
