Patent number: 7571728Abstract: A system and method to position and orient an excised breast tissue specimen on a support structure in a duplicate anatomic orientation relative to the operated breast is provided. One embodiment of the system includes an anatomically representative map of the breast under investigation. The system allows a surgeon to suture, ink, or otherwise fix the excised specimen on the map in accordance to its original position and orientation in the operated breast or organ. A radiogram of the excised specimen can be taken that shows the location of calcifications on a grid with radiopaque markers. The system allows a pathologist to cut through the specimen utilizing the map as a template in order to perform histological analysis and correlate the position and orientation of each slice to its anatomic position in the breast and thereby direct a precise and anatomically accurate re-excision by the surgeon if so required.Type: GrantFiled: April 8, 2004Date of Patent: August 11, 2009Assignee: Xoft, Inc.Inventors: Michael R. Forman, Darius Francescatti

Patent number: 6265016Abstract: A process for the preparation of slippery, hydrophilic polyurethane hydrogel coating compositions, and materials composed of a polymeric plastic or rubber substrate or a metal substrate with a coating of a slippery, hydrophilic polyurethane hydrogel thereon, such that the coating composition tenaciously adheres to the substrate, are disclosed. The coating compositions and coated materials are non-toxic and biocompatible, and are ideally suited for use on medical devices, particularly, catheters, catheter balloons and stents. The coating compositions, coated materials and coated devices demonstrate low coefficients of friction in contact with body fluids, especially blood, as well as a high degree of wear permanence over prolonged use of the device. The hydrogel coating compositions are capable of being dried to facilitate storage of the devices to which they have been applied, and can be instantly reactivated for later use by exposure to water.Type: GrantFiled: March 21, 2000Date of Patent: July 24, 2001Assignee: Schneider (USA) Inc.Inventors: Fritz Hostettler, David Rhum, Michael R.
