Patent number: 8439965Abstract: An angioplasty stent comprises a body comprising a plurality of successive segments connected in pairs by bridge means so that the successive segments can be oriented relative to one another for the purposes of bending of the body in any direction defined by a linear combination of respective orientation axes defined by the bridge connection means. During the radial expansion of the stent, the axial contraction of the segments resulting from the opening-out of the respective loops is compensated by axial projection of the bridge elements from the respective concave portions. The wall of the body comprises arms for supporting a lumen as well as regions which are selectively deformable during the expansion of the stent, the arms and the selectively deformable regions having different cross-sections and/or cross-sectional areas. At least one portion of the body may have a substantially reticular structure, the branches of which define geometrical figures identifiable as fractals.Type: GrantFiled: May 5, 2011Date of Patent: May 14, 2013Assignee: CID S.p.A.Inventors: Giovanni Rolando, Paolo Gaschino, Franco Vallana, Osvaldo Cerise

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
