Patent number: 7942874Abstract: The invention is concerned with cauterizing and resecting tissue. A pair of electrodes are placed on opposed tissue surfaces, and radio frequency power is applied through the electrodes to cauterizing a tissue mass therebetween. After cauterization has been effected, the tissue may be resected along a plane within the cauterized region with minimum or no bleeding. The tissue mass may then be removed.Type: GrantFiled: May 10, 2006Date of Patent: May 17, 2011Assignee: Aragon Surgical, Inc.Inventors: Joseph Eder, Camran Nezhat, Benjamin Theodore Nordell, II

Patent number: 7803156Abstract: The invention provides a surgical electrocautery method and apparatus that achieves sealing along the entire tissue length, and that also is able to deliver adequate force to produce an effective electrocautery seal. This problem is solved by using an incompressible fluid contained in a sac or sacs positioned to support the one or more electrodes used for electrocauterization. The profile of the electrodes thus conforms to the tissue surface and thickness variations, while exerting an optimized pressure along the entire length of the surface.Type: GrantFiled: March 8, 2006Date of Patent: September 28, 2010Assignee: Aragon Surgical, Inc.Inventors: Joseph Eder, Benjamin Theodore Nordell, II, Peter Seth Edelstein

Patent number: 7641651Abstract: An electrocautery device comprises first and second continuous loop electrode structures. The electrodes are typically coupled together at one end, permitting the electrodes to be introduced anteriorly and posteriorly over a uterine body. The electrodes may be clamped together, and radiofrequency energy may be delivered through the clamped electrodes to sever and cauterize blood vessels, tubular structures, and ligaments which connect the uterine body to surrounding tissue structures. The mobilized uterine body may then be removed by conventional hysterectomy.Type: GrantFiled: July 28, 2005Date of Patent: January 5, 2010Assignee: Aragon Surgical, Inc.Inventors: Camran Nezhat, Joseph Eder
