Customizable Haptic Assisted Robot Procedure System with Catalog of Specialized Diagnostic Tips

In accordance with the present disclosure, a system and method for using a remote control to control an electrosurgical instrument, where the remote controlled (RC) electrosurgical instrument has a universal coupling mechanism to allow switching between an interchangeable catalog of diagnostic tools. A controller within the base of the RC electrosurgical instrument identifies the type of disposable tip attached to the base. The controller, then, activates necessary features for use with the identified tip and deactivates any unnecessary features. A surgeon uses a remote with at least one momementum sensor to control the RC electrosurgical instrument 10. The surgeon rotates his hand mimicking movements of a handheld electrosurgical instrument, the movements of which are translated and sent to the RC electrosurgical instrument.

Ultrasound pulmonary vein isolation

A catheter introduction apparatus provides an ultrasound assembly for emission of ultrasound energy. In one application the catheter and the ultrasound assembly are introduced percutaneously, and transseptally advanced to the ostium of a pulmonary vein. An anchoring balloon is expanded to center an acoustic lens in the lumen of the pulmonary vein, such that energy is converged circumferentially onto the wall of the pulmonary vein when a transducer is energized. A circumferential ablation lesion is produced in the myocardial sleeve of the pulmonary vein, which effectively blocks electrical propagation between the pulmonary vein and the left atrium.

Blades with functional balance asymmetries for use with ultrasonic surgical instruments

Disclosed is an ultrasonic surgical instrument that combines end-effector geometry to best affect the multiple functions of a shears-type configuration. The shape of the blade is characterized by a radiused cut offset by some distance to form a curved geometry. The cut creates a curved surface with multiple asymmetries causing multiple imbalances within the blade. Imbalance due to the curve of the instrument is corrected by a non-functional asymmetry proximal to the functional asymmetry. Imbalance due to the asymmetric cross-section of the blade is corrected by the appropriate selection of the volume and location of material removed from a functional asymmetry. The shape of the blade in one embodiment of the present invention is characterized by two radiused cuts offset by some distance to form a curved and potentially tapered geometry. These two cuts create curved surfaces including a concave surface and a convex surface. The length of the radiused cuts affects, in part, the acoustic balancing of the transverse motion induced by the curved shape.
