摘要： A viewing and treatment apparatus for performing minimally invasive surgery through an opening in a patient's chest, the apparatus includes a visualization scope with an elongated portion and a distal end, and a working device such as a tissue ablation energy delivery device. The working device is encompassed within a working channel that communicates with the distal end of the scope. In one embodiment, a bronchoscope is used whose catheter shafting includes an introducer sleeve at the distal section of the scope for providing stability during introduction to a patient's chest while stabilizing the treatment and visualization distal ends of the scope at a treatment site. This embodiment can include a needle piercing assembly that cooperatively works with the working device such as for drug delivery. In a second embodiment a rigid endoscope with a viewing channel has an introducer member that is slidably disposed and detachable from the viewing channel and has a transparent convex distal tip which provides non-articulation at the distal end. This introducer member can also be used in conjunction with the first embodiment where the catheter shaft requires non-articulation. Both types of visualization scopes include a working channel in which the working device can translationally egress from the scope's distal end. Additionally, the rigid introducer member can be modified to include a movable transparent rotatable member design for varying the direction which the working devices egresses the apparatus' distal end.

Additionally, the rigid introducer member can be modified to include a movable transparent rotatable member design for varying the direction which the working devices egresses the apparatus' distal end. The preferred surgical procedure is transmyocardial revascularization and the preferred working device is an optical fiber element that is translatable from the distal end of the apparatus during the procedure. The working device can optionally include a flexible piercing needle with an internal lumen which allows translation of a working device such as an optical fiber or act as a conduit for drug delivery.

摘要： A tissue ablation system including numerous components and methods is described herein for encircling target tissue and generating tissue ablation volumes in various biological tissues. The biological tissue includes tissue of a variety of organs of the human body including the liver, spleen, kidney, lung, breast and other organs, but is not so limited. The tissue ablation device comprises an energy source and at least one trocar coupled to the energy source, the trocar having a body, a proximal end, and a distal end. The trocar carries an electrode array that comprises a plurality of electrodes, each electrode of the plurality of electrodes is configured to extend from the trocar when moved from a retracted state to a deployed state, and to have at least one radius of curvature in the deployed state so that the electrode array forms a series of shaped electrodes in the deployed state.

摘要： A method of operating a machine is disclosed. The machine may have a power system that includes a prime mover, a multiple-ratio transmission, a propulsion device, and power-system controls. The method may include propelling the machine by transmitting power from the prime mover to the propulsion device through the multiple-ratio transmission, while controlling operation of the prime mover and the multiple-ratio transmission with the power-system controls. This may include determining with the power-system controls at least one energy-efficiency estimate based at least in part on energy-efficiency characteristics of the prime mover and energy-efficiency characteristics of the multiple-ratio transmission. Controlling the prime mover and the multiple-ratio transmission may further include controlling a prime-mover operating speed of the prime mover and a transmission drive ratio of the multiple-ratio transmission based at least in part on the at least one energy-efficiency estimate.

摘要： An ablation device is described comprising an introducer and an electrode array. The electrode array couples to a distal end of the introducer. The electrode array includes a center member having a distal end configured to penetrate tissue and a plurality of electrodes. Proximal and distal ends of each electrode are relatively fixed. The electrodes are dynamically configurable from a retracted state to a deployed state in which the electrodes form a relatively spherical shape in a tissue volume.
