Patent dan rylands valve6/14/2023 ![]() The assembly includes a rigid suture guide holder having a surface against which the length of suture guide is releasably positioned. A ratchet is also included to maintain a closure force in the range of about 7 kg/cm 2 to about 13 kg/cm 2 between opposing sealing surfaces.read more read lessĪbstract: An assembly for holding a substantially flexible suture guide of predetermined length in a substantially taut position used to achieve a suture line having a dimension equal to the length of the suture guide, such as the circumference about a heart valve annulus. A stop is included for maintaining a minimum separation distance between opposing sealing surfaces. The jaw members connect to a source of electrosurgical energy such that the opposable sealing surfaces are capable of conducting electrosurgical energy through tissue held therebetween. The handle includes a fixed handle and a handle which is movable relative to the fixed handle to effect movement of the jaw members from the first position to the second position for grasping tissue. ![]() ![]() ![]() The tube includes first and second jaw members having electrically conductive sealing surfaces attached to a distal end thereof which are movable from a first position for approximating tissue to a second position for grasping tissue therebetween. Abstract: A laparoscopic bipolar electrosurgical instrument for sealing tissue includes a handle having an elongated tube affixed thereto.
