In this paper, an ablation apparatus including a maneuvering mechanism, a conductive element, a sensor attached to the apparatus and an output device in communication with the sensor is provided.Abstract:
An ablation apparatus including a maneuvering mechanism, a conductive element attached to the apparatus, a sensor attached to the apparatus and an output device in communication with the sensor is provided. The sensor senses vibration during the ablation procedure and sends a signal to the output device to reduce power to the conductive element.read more

Display screen or portion thereof with graphical user interface
TL;DR: Newness and distinctiveness is claimed in the features of ornamentation as shown inside the broken line circle in the accompanying representation as discussed by the authors, which is the basis for the representation presented in this paper.
Patent
Surgical stapling instrument with an articulatable end effector
TL;DR: In this paper, a surgical instrument can comprise a channel configured to support a staple cartridge and, in addition, an anvil pivotable between open and closed positions relative to the channel.
Patent
Articulating surgical stapling instrument incorporating a two-piece e-beam firing mechanism
TL;DR: In this article, an E-beam firing bar is used to drive staples on each side of the cut in a surgical severing and stapling instrument, which is suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil.

Patent
Impedance feedback monitor for electrosurgical instrument
TL;DR: In this article, an impedance monitoring device is provided for monitoring the electrical impedance of tissue as it is treated with electrosurgical energy, based on a predicted model of tissue impedance and a number of initial impedance readings, the impedance at which tissue treatment is completed is predicted.
Patent
Method and apparatus for thoracoscopic intracardiac procedures
TL;DR: A tubular access device having an inner lumen is provided for positioning through a penetration in a muscular wall of the heart, the access device has a means for sealing within the penetration to inhibit leakage of blood through the penetration as discussed by the authors.
Patent
Circumferential ablation device assembly
TL;DR: In this article, a circumferential ablation device assembly is presented which is adapted to forming a conduction block in a pulmonary vein, which circumscribes the pulmonary vein lumen and transects the electrical conductivity of the vein against conduction along its longitudinal axis.
