Patent number: 8391971Abstract: An apparatus for locally controlling smooth muscle tone includes a first electrode for insertion into an artery; a barrier for preventing the first electrode from contacting an arterial wall; a second electrode; a power supply; and a controller for coupling the power supply to the electrodes. The controller is configured to cause the electrode to maintain a waveform for controlling polarization of smooth muscle tone.Type: GrantFiled: September 7, 2011Date of Patent: March 5, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Roger Hastings, William J. Drasler, Vitaly Shapovalov, Mark Schroeder, Anupama Sadasiva

Publication number: 20070150009Abstract: Apparatus, system, and method that include a pacing apparatus having a stent electrode through which pulses of electrical current can be delivered. Stent electrodes receive energy for generating the electrical current from a variety of sources. Sources include from one or more induction coils that can form at least a portion of the stent. Sources can also include an implantable pulse generator coupled to a lead through which pulses of the electrical current are supplied to the stent electrodes.Type: ApplicationFiled: December 22, 2005Publication date: June 28, 2007Inventors: Graig Kveen, Roger Hastings, Anupama Sadasiva, Vitaly Shapovalov, Daniel Lafontaine

Publication number: 20050252893Abstract: A desired pattern may be cut into a stent preform by impinging a laser beam onto the stent preform. The laser beam is formed using a laser system comprising a resonator cavity for resonating laser radiation, a gain medium contained in the resonator cavity, a pump for periodically pumping the gain medium and an electro-optical modulator in communication with the resonator cavity. The laser system produces a radiation pulse for each pump period. Each radiation pulse is conditioned by suppressing at least a portion of the pulse. The pulse may also be modulated with an electro-optical modulator to produce a pulse train of ordered pulses of radiation. Each pulse train is output from the optical cavity as an output laser beam which is directed at the stent preform to cut a desired pattern in the stent preform.Type: ApplicationFiled: March 7, 2005Publication date: November 17, 2005Inventors: Vitaly Shapovalov, Vladimir Roussov, Vadim Veiko

Patent number: 6777647Abstract: A system for processing a work piece comprises a laser jet mechanism having a laser and a fluid source. The laser is constructed and arranged to transmit laser energy to the work piece and the fluid source is constructed and arranged to direct a fluid stream to the work piece. The laser energy is transmitted to the work piece through the fluid stream. The fluid stream comprises at least one processing solution selected from the group consisting of: at least one etchant, at least one abrasive, at least one polish, at least one cleaner, at least one detergent and any combination thereof. The fluid stream optionally comprises water.Type: GrantFiled: April 16, 2003Date of Patent: August 17, 2004Assignee: SciMed Life Systems, Inc.Inventors: Todd Messal, Kenneth Merdan, Vitaly Shapovalov, David Gilbert
