An ultrasound catheter with fluid delivery lumens, fluid evacuation lumens and a light source is used for the treatment of intracerebral hemorrhages. After the catheter is inserted into a blood clot in the brain, a lytic drug can be delivered to the blood clot via the fluid delivery lumens while applying ultrasonic energy to the treatment site. As the blood clot is dissolved, the liquefied blood clot can be removed by evacuation through the fluid evacuation lumens.

Method and apparatus for treatment of intracranial hemorrhages

A method of delivery ultrasonic energy and a therapeutic compound to a treatment site and an ultrasonic catheter system are disclosed. The ultrasonic catheter system comprises a tubular body having a proximal end, a distal end and a treatment zone located between the distal end and the proximal end, a fluid delivery lumen, at least one ultrasound radiating element positioned in the treatment zone, wiring electrically coupled to the at least one ultrasound radiating element and extending through the tubular body and terminating at a connector, and a control system comprising external circuitry and an isolation pod that is configured to be electrically connected to the connector, the isolation pod being positioned between the tubular body and the external system and comprising an isolation barrier and circuitry for driving the ultrasound radiating element.

Catheter with multiple ultrasound radiating members

An ultrasound catheter with a lumen for fluid delivery and fluid evacuation, and an ultrasound source is used for the treatment of intracerebral or intraventricular hemorrhages. After the catheter is inserted into a blood clot, a lytic drug can be delivered to the blood clot via the lumen while applying ultrasonic energy to the treatment site. As the blood clot is dissolved, the liquefied blood clot can be removed by evacuation through the lumen.

A method for treating an occlusion comprises positioning a catheter at a treatment site in a patient's vasculature. A blockage is located at the treatment site. The method further comprises performing a medical treatment at the treatment site. The medical treatment is configured to reduce the blockage. The method further comprises making a plurality of measurements at the treatment site.

Method and apparatus for detecting vascular conditions with a catheter

A catheter system for delivering ultrasonic energy to a treatment site includes a tubular body having a proximal end, a distal end and a treatment zone located between the distal end and the proximal end. An ultrasonic assembly is positioned within the treatment zone and provides providing an average longitudinal power density between about 0.2 and about 1.0 W/cm within the treatment zone.

A method of delivery ultrasonic energy and a therapeutic compound to a treatment site and an ultrasonic catheter system are disclosed. The method comprises providing a catheter with a plurality of ultrasound radiating members, wherein the plurality of ultrasound radiating members are allocated into electrical groups comprising more than one ultrasound radiating member. The method further comprises independently driving each group of ultrasonic radiating members, and delivering the therapeutic compound through the catheter to the treatment site.

A decorative charm and fastener system and its method for use upon an item to be worn by the user or a pet animal; the item to be worn may be a shoe, an item of clothing (including shirts, hats and caps, or the like), or a pet collar. The fundamental embodiment features a charm part and a base part that may be connected together on opposite sides of the item to be worn, with the item situated between the base part and the charm part. The system also includes an elastically compressible washer member that is placed upon the charm part. The compressible washer promotes a secure, yet temporary, connection between the charm part and base part when those respective parts are installed upon an item. Assortments of different charms thus are interchangeable for temporary attachment to the base part. Specialized alternative versions of the apparatus are disclosed for use upon the shoelaces of a shoe, as a pet collar. A variety of decorations accordingly may selectively be used in combination with a shoe, pet collar, or other item.

Apparatus and method for securely yet removably attaching ornaments to shoes, clothing, pet collars and the like

A catheter for delivering ultrasonic energy and therapeutic compounds to a treatment site within a patient's vasculature comprises a tubular body. The tubular body has a proximal region and a distal region opposite the proximal region. The catheter further comprises a plurality of fluid delivery lumens formed into the tubular body. The catheter further comprises an inner core configured for insertion into the tubular body. The inner core comprises an elongate electrical conductor having a plurality of flattened regions, each flattened region having a first flat side and a second flat side opposite the first flat side. The inner core further comprises a plurality of ultrasound radiating members mounted in pairs to the flattened regions of the elongate electrical conductor. A first ultrasound radiating member is mounted to the first flat side of the elongate electrical conductor, and a second ultrasound radiating member is mounted to the second flat side of the elongate electrical conductor. The catheter further comprises control electronics configured to apply a driving signal to at least two, but fewer than all, of the ultrasound radiating members.

Apparatus and methods for perfusing ischemic myocardium, and optionally, for reducing the load on a patient's left ventricle, are provided using a inlet conduit having an inlet end configured for insertion into an oxygenated blood source, including without limitation, the left atrium, left ventricle, aorta, pulmonary vein, subclavian artery, brachiocephalic artery, radial artery or femoral artery, coupled to an outlet conduit having an outlet end configured for insertion into the coronary venous vasculature via the coronary ostium. The inlet conduit may include a stylet or elastomeric sleeve that facilitates placement, while the outlet conduit may include a valve for limiting a peak pressure attained in the coronary venous system. A motor-driven or hydraulically-actuated pump optionally may be coupled in the flow path, and control circuitry provided to control the pump with a user selected duty cycle.
