Abstract:
An apparatus, system, and method for isometric exercise that safely reduces resting blood pressure and increases overall cardiovascular health. The apparatus (100) includes a handle or grip (103, 104) configured to provide natural resistance to force and maximize user comfort. The system includes squeezing the handle or grip (103, 104) of the apparatus (100) with a force (113, 114) that is less than the maximum squeeze force of the user, thereby reducing blood flow through contracting arm muscles and safely increasing blood pressure during exercise. Resting blood pressure is reduced through regular use of the system. The method includes measuring and recording the maximum squeeze force of a user (900, 1001, 1003), calculating a fractional force (1005, 1007) using the duration of exercise or a desired fractional force percentage, and alternately inducing the user to apply the fractional force (1005, 1007) for a calculated time and inducing the user to apply a lesser fractional force or no force for a calculated time.
Abstract:
An electrosurgical device includes a body, an end effector, a cutting member, and a shaft. The end effector comprises a pair of jaws and at least one electrode that is operable to deliver RF energy to tissue clamped between the jaws. The cutting member is operable to cut tissue clamped between the jaws. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. The body includes a controller operable to selectively actuate the articulation section. The controller may include a rotary knob, a pivoting knob, or a pivoting fin, among other things. An electrical coupling may contact a conductive moving member along at least two axes. A resiliently biased lever may assist a trigger in returning from an actuated position to a home position.

The controller may include a trigger that also drives the cutting member, a rotator that also rotates the shaft and end effector, a wedge- shaped pivoting member, a pivotally coupled pair of housing portions, or a pivoting cam member, etc. A release member may selectively release the articulation section from the controller, allowing a resilient bias to return the end effector into alignment with the shaft.
Abstract:
An ultrasonic surgical instrument comprises a handpiece and an ultrasonically actuated blade distal to the handpiece. The instrument includes an activation member that is operable to selectively activate the blade and a controller that is operable to select the energy level at which the blade will be activated. The activation member may comprise capacitive switches; resistive sensors; resonant cavity switching technology; infrared sensing technology; technology that uses a resonant, standing wave on a surface that is perturbed by the presence of a finger; and/or any other suitable type of technology. The controller may comprise the same. The controller may permit selection from three or more available ultrasonic energy levels. The activation member and/or controller may be manipulated from various longitudinal positions on the handpiece and/or various rotational positions about the handpiece, such that the handpiece may be gripped in a variety of ways.

Abstract:
The invention describes methods, devices, kits and systems for isolating one or more teeth. The devices include a topology conformable device that can be constrained into a shape that can be delivered into an oral cavity and unconstrained to allow the device to isolate a target tooth and initiate a working field.
