  • Patent number: 6605084
    Abstract: A treatment catheter (10) carries an elongated ultrasonic emitter (20) extending in the lengthwise direction of the catheter. The array is flexible in all directions transverse to the lengthwise direction. The treatment catheter is inserted into a chamber of the heart and brought to a desired configuration such as a substantially closed loop. The treatment catheter is then biased into engagement with the wall of the heart by an expansible balloon (62) or other expansible structure, which may be carried on a separate stabilizer catheter (60). While the treatment catheter is engaged with the heart wall, the array is actuated to ablate tissue along a path having a shape corresponding to the configuration of the treatment catheter.
    Type: Grant
    Filed: March 23, 2001
    Date of Patent: August 12, 2003
    Assignee: Transurgical, Inc.

  • Patent number: 4726374
    Abstract: A hemostasis valve, for example, for a catheter for entering coronary blood vessels. The valve defines an adjustable high pressure seal and a second seal of typically lower pressure resistance.

  • Patent number: 4723550
    Abstract: A hemostasis valve in which the valve member is a tubular, resilient gasket which may be compressed with variable pressure to provide a variable pressure seal to an elongated member extending through the tubular bore of the gasket. The gasket bore also defines at least one resilient, annular rib whereby the elongated member passing through the tubular gasket bore may be subjected at all times to at least a relatively low pressure seal from the resilient, annular rib, irrespective of the pressure of the variable pressure seal. Additionally, the pressure on the gasket may be applied and released by means of a pressure member positioned against the gasket. Structure is provided permitting longitudinal motion, but preventing rotational motion, of the pressure member.
