Publication number: 20210137580Abstract: A surgical apparatus and methods for severing and welding tissue, in particular blood vessels. The apparatus includes an elongated shaft having a pair of relatively movable jaws at a distal end thereof. A first heating element on one of the jaws is adapted to heat up to a first temperature and form a welded region within the tissue, while a second heating element on one of the jaws is adapted to heat up to a second temperature and sever the tissue within the welded region. The first and second heating elements may be provided on the same or opposite jaws. A control handle provided on the proximal end of the elongated shaft includes controls for opening and closing the jaws, and may include an actuator for sending current through the first and second heating elements. The first and second heating elements may be electrically connected in series, and the first heating element may be bifurcated such that it conducts about one half of the current as the second heating element.Type: ApplicationFiled: November 3, 2020Publication date: May 13, 2021Applicant: MAQUET CARDIOVASCULAR LLCInventors: Liming LAU, Arnold M. ESCANO, Jerry JARRARD, Samuel HO, Ryan C. ABBOTT, Arthur M. LIN, Jesse MCQUISTON, Kenny L. DANG
