Abstract
A catheter is disclosed. The catheter includes an elongated body with an exterior surface and an ultrasound transducer with a longitudinal length. A support member supports the ultrasound transducer at the exterior surface of the elongated body and defines a chamber adjacent to the exterior surface of the elongated body. The chamber reduces transmission of ultrasound energy from the ultrasound transducer into the elongated body along the longitudinal length of the ultrasound transducer.
Claims40
A catheter, comprising:
- an elongated body with an exterior surface;
- an ultrasound transducer with a longitudinal length;
- and
- a support member supporting the ultrasound transducer at the exterior surface of the elongated body, the support member at least partially defining a chamber adjacent to the exterior surface of the elongated body, the chamber reducing transmission of ultrasound energy from the ultrasound transducer into the elongated body along the longitudinal length of the ultrasound transducer;
- and
- a support positioned between the support member and the elongated body.
3 more elements
A catheter, comprising:
- an elongated body with an exterior surface;
- an ultrasound transducer;
- and
- a support member supporting the ultrasound transducer in a spaced apart relationship from the exterior surface of the elongated body such that a chamber is formed between the support member and the exterior surface of the elongated body, wherein the chamber is filled with a low acoustic impedance material.
