Patent number: 9168105Abstract: A device for locating an operational unit within a patient's body within the framework of a minimally-invasive surgery intervention includes a shaft having a distal end carrying an operational unit. The device includes an illuminator located at the distal end of the shaft. The illuminator is selectively adjustable to provide a selectively variable lighting field in correspondence with the operational unit. The device may be, for example, a delivery system for a heart valve or a balloon device for post-dilation of such a heart valve once implanted.Type: GrantFiled: May 13, 2009Date of Patent: October 27, 2015Assignee: Sorin Group Italia S.r.l.Inventors: Arnaldo Giannetti, Laura Ghione, Paolo Gaschino, Giovanni Righini

Patent number: 8403982Abstract: A device for deploying a cardiac valve prosthesis includes at least one constraint member for radially constraining radially expandable annular portions of the valve. The constraint member is actuatable to release the annular formations constrained thereby and permit radial expansion of these annular formations. The constraint member has associated a first, slow-acting actuating mechanism and a second, fast-acting mechanism, adapted to produce relatively slow and fast release of the annular formations constrained thereby. The device may include a first constraint member and second constraint member in the form of telescoping sleeves. The slow-acting actuating mechanism will thus act on the outer sleeve, while the fast-acting mechanism will act on the inner sleeve to produce, respectively, slow and fast release of the annular formations.Type: GrantFiled: May 13, 2009Date of Patent: March 26, 2013Assignee: Sorin Group Italia S.r.l.Inventors: Arnaldo Giannetti, Laura Ghione, Paolo Gaschino

Patent number: 6630989Abstract: A method for determining the concentration of heparin in a fluid sample comprising: (a) providing a fluid sample containing heparin; (b) adding to the fluid sample a solution of a dye to form a mixture of sample and dye, wherein the dye interacts with the heparin in the sample so that the absorption spectrum of the mixture of sample and dye in the visible range varies as a result of the interaction in a manner quantitatively dependent on the heparin concentration; (c) determining the absorption spectrum in the visible range of the mixture of sample and dye; and (d) calculating a spectral parameter representative of both the reduction in the absorption of the free dye in solution and the increase in the absorption of the dye-heparin complex, the value of the spectral parameter being indicative of the concentration of heparin present in the fluid sample, in order to determine the concentration of heparin present in the fluid sample.Type: GrantFiled: October 11, 2000Date of Patent: October 7, 2003Assignee: Dideco S.p.A.Inventors: Giuseppe Caputo, Raffaele Castelli, Elena Comoglio, Leopoldo Della Ciana, Arnaldo Giannetti

Patent number: 6572642Abstract: A prosthesis having an apertured structure is located in a chamber (11) which is taken to sub-atmospheric pressure. Once sub-atmospheric pressure has been reached, a liquid, optionally containing pharmacological agents, is introduced into the chamber. Drawn by the sub-atmospheric pressure, the liquid saturates the apertured structure of the prosthesis. In this way, the invention eliminates the risk of air being trapped in the apertured structure that could give rise to the formation of blood clots after implantation of the prosthesis. The liquid can contain drugs that penetrate the prosthesis, performing their therapeutic action locally and over time after implantation.Type: GrantFiled: April 30, 2002Date of Patent: June 3, 2003Assignee: Sorin Biomedica Cardio S.p.A.Inventors: Stefano Rinaldi, Arnaldo Giannetti, Enrico Pasquino
