Operating Room Multifunction Cable System
20230095290 · 2023-03-30 ·

An improved multifunction cable for use in an operating room avoids the usual tangle of wires and tubes can be a significant hazard. The cable comes pre-sterilized with a number of wires and tubes pre-installed in a protective housing making it easy to conduct myriad wires and tubes from one region of the operating room to another without any possibility of tangling or violation of sterility. At the sterile end of the cable a special terminus acts as a holder to keep the various operating instrument organized. The terminus is designed to accept a special smoke evacuating monopolar electrosurgery instrument.

ELECTROSURGICAL APPARATUS WITH FLEXIBLE SHAFT

An electrosurgical apparatus is provided including a connector, a flexible shaft, and a distal tip. The connector may further be coupled to an electrosurgical generator and gas supply. The distal tip of the electrosurgical apparatus may be grasped by a grasping tool, such that the orientation and position of the distal tip relative to the shaft may be manipulated to achieve a plurality of positions. The electrosurgical apparatus provides electrosurgical energy and inert gas to an electrode within the distal tip of the electrosurgical apparatus to generate a plasma beam. In one aspect, the distal tip is configured as a sheath that is extendable and retractable over the electrode to expose the electrode when the sheath is in a first position and conceal or cover the electrode when the sheath is in a second position.

20230099410 · 2023-03-30 ·

An ablation system, configured to create a shunt between a left atrium and a coronary sinus of a patient, includes an ablation device comprising a proximal body defining a distal-facing surface configured to contact the coronary sinus wall, a distal body defining a proximal-facing surface positioned opposite the distal-facing surface and configured to contact the left atrium wall, and first and second heating elements disposed on the distal-facing and proximal-facing surfaces, respectively. The heating elements are configured to ablate tissue between the left atrium and the coronary sinus of the patient to create the shunt. The system further includes an expandable dilation element configured to dilate a puncture formed through the coronary sinus wall and the left atrium wall to facilitate introduction of the distal body of the ablation device into the left atrium.

Methods for monitoring ablation progress with doppler ultrasound
11612431 · 2023-03-28 · ·

Systems and methods for treating tissue are disclosed. The target tissue is ablated. A real-time image of the target tissue is generated during the ablation. The real-time blood perfusion level of the target tissue is determined from the real-time image and compared to an initial blood perfusion level of the target tissue. The comparison provides a metric for the progress of the ablation, and ablation is halted when the real-time blood perfusion drops below a threshold level relative to the initial blood perfusion level.

BIPOLAR ENERGY-BASED SURGICAL INSTRUMENTS

An electrosurgical instrument has a hollow shaft portion defining a plurality of fluid ports configured for suction and/or irrigation. The electrosurgical instrument also includes a plurality of different electrode tips configured to detachably couple to the shaft portion. Each of the electrode tips have an active electrode and a return electrode to provide bipolar electrosurgical energy therebetween.
