Patent number: 11696798Abstract: A vessel sealing device having a pair of electrodes that are maintained in spaced apart configuration when closed by non-uniform coating formed from a non-conductive material that has been applied to roughened electrodes so that the coating allows for the passage of a predetermined amount of radiofrequency (RF) energy between the electrodes. The coating has a predetermined thickness that spaces the electrodes apart while also having the predetermined non-uniformity that allows RF energy to pass between the electrodes when a vessel is trapped therein, thus desiccating the vessel positioned in the jaws. The electrodes may include a series of grooves in a herringbone pattern, with each electrode having the pattern oriented in the same direction or in opposite directions.Type: GrantFiled: June 15, 2018Date of Patent: July 11, 2023Assignee: CONMED CORPORATIONInventors: Roberto Del Cid, Michael Lontine, Michael Olichney, Mason Williams

Patent number: 11612429Abstract: Ablation systems and methods detect and address distortion caused by a variety of factors. A method includes measuring a temperature curve at target tissue; applying ablation energy to the target tissue; determining a peak temperature on the temperature curve; if the peak temperature is greater than the predetermined peak temperature, determining a time at which the temperature curve crosses to a lower temperature; and if the determined time is greater than a predetermined time, generating a message indicating that the target tissue was successfully ablated. Another method includes determining a distance between a remote temperature probe and an ablation probe, applying ablation energy to target tissue, measuring temperature at the remote temperature probe, estimating ablation size based on the determined distance and the temperature measured by the remote temperature probe, and determining whether the target tissue is successfully ablated based on the estimated ablation size.Type: GrantFiled: May 31, 2018Date of Patent: March 28, 2023Assignee: Covidien LPInventors: Joseph D.
