Patent number: 10433966Abstract: A set of distal femoral knee prostheses which are designed to be more narrow in medial/lateral dimensions with increasing anterior/posterior size than existing prostheses to more closely correspond to the physical anatomy of female patients. The prostheses are designed to have a substantially trapezoidal shape or profile when viewed distally which features a more pronounced narrowing of the medial/lateral dimensions beginning at the posterior end of the prostheses and progressing anteriorly to the anterior end of the prostheses. Additionally, the prostheses each include a reduced profile patellar sulcus and reduced profile anterior condyles to more closely conform to the anatomy of a resected femur, and also include sulcus tracking optimized to conform to female anatomy.Type: GrantFiled: February 3, 2017Date of Patent: October 8, 2019Assignee: Zimmer, Inc.Inventors: Brian D. Earl, Abraham P Habegger, Aaron Hofmann, Kim Bertin, Lawrence Dorr, Robert E Booth, Jr., Aaron Rosenberg, Sergio Romagnoli

Patent number: 9763677Abstract: Rasps for preparing bones of various patients to receive a prosthetic implant and a method for using the same. Multiple rasps may be provided as a set. Within the set, the rasps generally correspond to the size and shape of a single prosthetic implant, such as a prosthetic femoral hip stem, and have a range of bone removal and bone compression capabilities to account for unique bone characteristics of the various patients. A surgeon may select a desired rasp from the set provided depending on the patient's unique bone characteristics.Type: GrantFiled: October 8, 2014Date of Patent: September 19, 2017Assignee: Zimmer GmbHInventors: Sergio Romagnoli, Roland Willi

Publication number: 20090299481Abstract: An implant (6) is provided for implantation in a condyle (21) of a proximal tibia. The implant is shaped in such a way that an anterior edge (63) at least approximately simulates the anterior contour of the tibial plateau (2). The implant is dimensioned such that it does not extend as far as the margin of the tibial plateau in the posterior and lateral directions and is shaped like a plate in such a way that it is free from form-fit anchoring elements and can be pushed in the manner of a drawer into a recess of the tibial plateau and can be cemented. The implant permits maximum preservation of the bone tissue and soft tissue, and the necessary resection and the implantation can both be performed by what is essentially a purely anterior approach.Type: ApplicationFiled: February 1, 2007Publication date: December 3, 2009Applicant: ZIMMER GMBHInventor: Sergio Romagnoli

Patent number: 7311849Abstract: The invention provides a control device for the separate collection of blood components in output from a blood centrifugation cell. The control device comprises: a support which comprises a recess for containing a duct; a visible-light emitter with a corresponding receiver, which are arranged on opposite sides with respect to the recess for containing the duct; an infrared-light emitter with a corresponding receiver, which are arranged on opposite sides with respect to the recess for containing the duct; and a processor to detect signals acquired by the two receivers, to calculate a ratio between the values of the signals, and to send signals to the means suitable to selectively send the fluid conveyed by the duct into separate collection bags, the means being able to change the bag in which the fluid is collected.Type: GrantFiled: July 23, 2004Date of Patent: December 25, 2007Assignee: Sorin Group Italia S.r.l.Inventors: Ivo Panzani, Sergio Romagnoli, Ivan Rossi, Stefano Sarti

Patent number: 7156800Abstract: A method and apparatus for controlling the washing step in a blood centrifugation cell in which washing solution is introduced into the blood centrifugation cell and the cell contains compacted red cells and supernatant at the beginning of the washing step. The apparatus can comprise various sensors and a computer. The sensors sense and transmit to the computer three inputs. The first input is indicative of the total volume of blood that enters the cell during the filling step and the total amount of washing solution that enters the cell during the washing step. The second input is indicative of the hematocrit value of the blood introduced during the filling step. The third input is indicative of the geometric characteristics of the cell. Based on the inputs, the computer executes an algorithm that produces a first output that is the concentration of the supernatant in the supernatant-washing solution mixture.Type: GrantFiled: December 13, 2005Date of Patent: January 2, 2007Assignee: Sorin Group Italia S.r.l.Inventors: Ivo Panzani, Sergio Romagnoli, Massimo Belloni
