Patent number: 9308042Abstract: Methods for using a surgical device integrating a suction mechanism with a coagulation mechanism for improving lesion creation capabilities. The device comprises an elongate member having an insulative covering attached about means for coagulating soft tissue. Openings through the covering expose regions of the coagulation-causing elements and are coupled to lumens in the elongate member which are routed to a vacuum source and a fluid source to passively transport fluid along the contacted soft tissue surface in order to push the maximum temperature deeper into tissue.Type: GrantFiled: May 30, 2013Date of Patent: April 12, 2016Assignee: nContact Surgical, Inc.Inventors: James G. Whayne, Sidney D. Fleischman, Earl W. Rogers

Publication number: 20150250538Abstract: An embodiment of the invention includes a surgical device for coagulating soft tissue such as atrial tissue in the treatment of atrial fibrillation, atrial flutter, and atrial tachycardia; tendon or ligament shrinkage; or articular cartilage removal. The surgical device integrates a suction mechanism with the coagulation mechanism improving the lesion creation capabilities of the device. The surgical device comprises an elongate member having an insulative covering attached about conductive elements capable of coagulating soft tissue when radiofrequency or direct current energy is transmitted to the conductive elements. Openings through the insulative covering expose regions of the conductive elements and are coupled to lumens in the elongate member which are routed to a vacuum source. Suction causes the soft tissue to actively engage the opening thus the integrated, exposed conductive elements to facilitate the coagulation process and ensure the lesions created are consistent, continuous, and transmittal.Type: ApplicationFiled: May 8, 2015Publication date: September 10, 2015Applicant: nContact Surgical, Inc.Inventors: James G. WHAYNE, Sidney D. FLEISCHMAN

Publication number: 20150250537Abstract: Methods and devices are disclosed herein for therapeutically treating atrial tissue to lessen the effects of mechanical stress on atrial tissue, where reducing mechanical stress in the portion of atrial tissue reduces formation of at least one arrhythmia substrate. In one example, the devices and methods are suitable for minimally invasive surgery. More particularly, methods and devices described herein permit creating an ablation pattern on an organ while reducing excessive trauma to a patient.Type: ApplicationFiled: January 26, 2015Publication date: September 10, 2015Applicant: nContact Surgical, Inc.Inventors: James G. WHAYNE, Sidney D. FLEISCHMAN
