Abstract
Systems, devices, and methods provide a solid-state intravascular ultrasound (IVUS) imaging system that includes an array of ultrasound transducers mounted on a structural uni-body made of a polymeric substance doped with acoustic dampening material. The use of the polymeric substance doped with acoustic dampening material to fabricate the uni-body assists in improving the signal-to-noise ratio associated with the IVUS imaging signals.
Claims24
An intravascular ultrasound (IVUS) device, comprising:
- a scanner assembly including,
- a ferrule including a lumen region;
- a uni-body surrounding at least a portion of the ferrule, the uni-body including a polymeric substance doped with acoustic dampening material;
- and
- a flex circuit mounted onto the uni-body, the flex circuit including a transducer array.
A method of forming a scanner assembly of an intravascular ultrasound (IVUS) device, the method comprising:
- providing a polymeric material doped with acoustic dampening material;
- fabricating a uni-body with the doped polymeric material;
- and
- mounting a flex circuit having a transducer array onto the fabricated uni-body.
