Abstract: Various embodiments are directed to articulatable surgical instruments. Some embodiments comprise an end effector to treat tissue, where the end effector comprises an ultrasonic blade. A hollow shaft may extend proximally from the end effector along a longitudinal axis. A waveguide may extend through the shaft and may be acoustically coupled to the ultrasonic blade. The waveguide may comprise a distally positioned flange positioned within the hollow shaft proximally from the blade and may be held stationary at a first pivot point positioned within the hollow shaft proximally from the flange. A reciprocating wedge may be positioned within the hollow shaft such that distal motion of the wedge pushes the wedge between the flange and the hollow shaft, causing the ultrasonic blade to pivot about the first pivot point in a first direction.

Abstract: The present invention relates to a flexible surgical system for endoscopic spinal decompression and methods thereof. Various methods of accessing the epidural space with this instrument are described. The system design enables placement of the device through several approaches. It is then advanced under direct visualization or fluoroscopic (X-Ray), for example, into areas of the spine including lumbar (low back), thoracic (mid and upper back) and cervical (neck). The pathologies encroaching upon the spinal space can then be visualized wherein the epidural membrane can optionally be displaced to further aid in visualization. The membrane can be used to protect regions of tissue adjacent the site to tissue removal.

Abstract: Apparatus (220/20) and methods are described including a transluminal ablation catheter (40) that includes at least one ultrasound transducer (50/52/150). The at least one ultrasound transducer is inserted into a chamber (190) of a subject's heart and is configured (a) to ablate tissue of the subject by applying ultrasound energy to the tissue, and (b) to image tissue of the subject by applying non-ablating ultrasound energy to the tissue. An expandable cage (30/301) is disposed around the at least one ultrasound transducer. The at least one ultrasound transducer is configured to rotate and axially translate back and forth within the expandable cage, such as to generate a three-dimensional image of the tissue. Other applications are also described.

Abstract: According to some embodiments, a method of treating a subject having diabetes or symptoms associated with diabetes is provided. The method includes delivering a neuromodulation catheter within a vessel (e.g., hepatic artery) having surrounding nerves that innervate the liver (e.g., sympathetic nerves of the hepatic plexus). The method may also include modulating (e.g., disrupting, ablating, stimulating) the nerves by mechanical compression, energy delivery, or fluid delivery.

Abstract: A stapling system including a housing that has a first rotatable disk configured to transmit a first operative motion and a second rotatable disk configured to transmit a second operative motion is disclosed herein. The second rotatable disk is operable independently of said first rotatable disk. The stapling system further includes an end effector, an elongate rigid shaft, and a drive system. The drive system is responsive to the first operative motion from the first rotatable disk to perform a closing motion of the end effector and responsive to the second operative motion from the second rotatable disk to perform a firing stroke. A control system is configured to assure that the closing motion and the firing stroke are separate and distinct, wherein the control system prevents the firing stroke from occurring prior to the completion of the closing motion.

Abstract: A surgical device. The surgical device may comprise a transducer, an end effector, a generator and a control circuit. The transducer may be configured to provide vibrations. The end effector may be coupled to the transducer and may extend from the transducer along the longitudinal axis. The generator may provide an electrical signal to the transducer. Also, the control circuit may modify a current amplitude of the electrical signal in response to a change in a vibration frequency of the end effector. Accordingly to various embodiments, the control circuit may detect a first contribution to a vibration frequency of the end effector, the first contribution originating from tissue in contact with the end effector. Also, according to various embodiments, the control circuit may indicate a change in a vibration frequency of the end effector.

Abstract: An ultrasonic instrument comprises an ultrasonic transducer, an acoustic waveguide, and an ultrasonic blade. The blade includes a pair of obliquely extending edges. The obliquely extending edges diverge away from the longitudinal axis of the waveguide and away from each other along respective paths extending distally in relation to the waveguide. A distal portion of the blade is wider than a proximal portion of the blade along a plane. The blade further includes a curved distal edge and several laterally presented surfaces. The laterally presented surfaces may provide combinations of concave and convex curvatures. The laterally presented surfaces may be angled and/or curved along one or more orthogonal planes associated with the longitudinal axis of the waveguide.

Abstract: Disclosed are methods of producing randomized ultrasound waves for providing sonodynamic therapy. The method includes coupling a sonodynamic therapy device with an array of piezoelectric transducer elements to a skin surface. A controller is configured to generate an electrical drive signal to produce ultrasound waves to activate a sonosensitizer in a treatment region without damaging healthy cells in the treatment region.

Abstract: A surgical apparatus includes a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and a rigidizing member. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide includes a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section includes a first member and a second member. The second member is longitudinally translatable relative to the first member. The end effector includes an ultrasonic blade in acoustic communication with the waveguide. The rigidizing member is configured to selectively engage at least a portion of the articulation section to thereby selectively provide rigidity to the articulation section.
