Patent number: 7294126Abstract: Disclosed is an ablation method and apparatus used to close veins for treatment of venous insufficiency disease. The apparatus includes a catheter proportioned for insertion into a vein, a pair of inflatable balloons spaced apart on the catheter body, and an ablation electrode array disposed between the balloons. According to the disclosed method, the catheter is introduced into the vein to be treated and the balloons are distended. Blood is flushed and aspirated from the site between the balloons. RF power is applied to the electrode array, causing scarring of the vessel walls and eventual sealing of the vein.Type: GrantFiled: January 5, 2004Date of Patent: November 13, 2007Assignee: CYTYC CorporationInventors: Russell M. Sampson, Eugene Skalnyi, Estela Hilario

Patent number: 7063670Abstract: A system and method for detecting perforations in a body cavity. In accordance with the method of the invention, a fluid (liquid or gas) is delivered into a body cavity to slightly pressurize the cavity. A pressure sensing system monitors the pressure within the cavity for a predetermined test period. If cavity pressure is not substantially sustained during the test period, the physician is alerted to further assess the cavity for perforations before initiating treatment within the cavity. In a preferred form of the system, a medical treatment system such as an RF ablation system is provided with perforation detection functionality. The system preferably includes a pre-test and post-test lockout system.Type: GrantFiled: February 11, 2005Date of Patent: June 20, 2006Assignee: Cytyc Surgical ProductsInventors: Russell M. Sampson, Mike O'Hara, Csaba Truckai, Dean T. Miller

In a preferred form of the system, a medical treatment system such as an RF ablation system is provided with perforation detection functionality. The system preferably includes a pre-test and post-test lockout system. The lockout system prevents RF power delivery unless, during a predetermined test period, the pressure sensing system determines that no perforation exists, or unless a previously performed perforation detection procedure determined a perforation was present but the lockout system was subsequently overridden by the physician.Type: GrantFiled: November 10, 2000Date of Patent: April 29, 2003Assignee: NovaceptInventors: Russell M.
