Abstract
A catheter for ultrasonic-driven bladder therapeutic agent delivery, including: a tube having a proximal expandable portion and a distal end, and at least one transducer sleeve accommodating at least one ultrasound transducer mounted on the tube between the proximal expandable portion and the distal end.
Claims18
A catheter for ultrasonic-driven bladder therapeutic agent delivery, comprising a tube having:
- at least one first port;
- a proximal expandable portion, expandable via the at least one first ports;
- at least one inflatable transducer sleeve accommodating at least one ultrasound transducer mounted on said tube between said proximal expandable portion and a distal end of the tube, wherein said at least one inflatable transducer sleeve is expandable via the at least one first ports;
- and
- one or more second ports positioned along a circumference of a surface of said distal end of the tube, wherein said one or more second ports are adapted to perform at least one of:
- inserting therapeutic fluid into a bladder lumen, inserting tissue cleaning fluid into the bladder lumen, and removing fluid from the bladder lumen,
- wherein the at least one inflatable transducer sleeve and said proximal expandable portion are in fluid communication,
- wherein said at least one ultrasound transducer is surrounded by degassed acoustic fluid in a volume defined by the at least one inflatable transducer sleeve,
- and wherein the degassed acoustic fluid is configured to allow acoustic waves to travel from the at least one ultrasound transducer to the at least one inflatable transducer sleeve without generating cavitation.

A catheter for ultrasonic-driven bladder therapeutic agent delivery, comprising a tube having:
- an expandable portion, expandable via two or more first ports;
- at least one inflatable transducer sleeve accommodating at least one ultrasound transducer mounted on said tube between said expandable portion and a distal end of the tube, wherein said at least one inflatable transducer sleeve is expandable via the two or more first ports;
- and
- one or more second ports positioned along a circumference of a surface of said distal end of the tube, wherein said one or more second ports are adapted to perform at least one of:
- inserting therapeutic fluid into a bladder lumen, inserting tissue cleaning fluid into the bladder lumen, and removing fluid from the bladder lumen,
- wherein said two or more first ports comprise a fluid supply port and a fluid removal port in fluid communication with a lumen of said at least one inflatable transducer sleeve,
- and wherein said at least one ultrasound transducer is positioned between the fluid supply port and said fluid removal port,
- and wherein said fluid supply port and said fluid removal port are adapted to maintain flow of degassed acoustic fluid therebetween, to cool the at least one ultrasound transducer by heat convection.
