US Patent:

20190175872, Jun 13, 2019

Filed:

Jun 23, 2016

Appl. No.:

16/308980

Inventors:

- Alpharetta GA, US
Steve S. Khalaj - Laguna Hills CA, US
Paul D. Jun - La Crescenta CA, US

International Classification:

A61M 25/01
A61B 8/08

Abstract:

The present invention is directed to an echogenic catheter assembly. The catheter assembly includes a catheter having a proximal end and a distal end that defines a lumen extending from the proximal end to the distal end. Further, the catheter assembly includes a coil member configured with at least a portion of the lumen of the catheter. The coil member forms a plurality of outwardly extending projections. One or more of the outwardly extending projections define a cross-sectional shape having at least one non-arcuate edge. As such, the non-arcuate edges of the outwardly extending projections are configured to enhance ultrasonic imaging of the catheter when inserted into a patient.

A61J 1/05

Abstract:

An elastomeric pump having at least one sensor for sensing changes in elongation of a bladder of the pump is provided. Also provided is an infusion assembly including an elastomeric pump having a bladder, at least one sensor for sensing changes in elongation of the bladder, and an indicator for providing one or more outputs of the sensor. The sensor may be a flexible sensor positioned in contact with the bladder of the pump, or a dielectric material may be incorporated into the material the bladder is made from such that the dielectric elastomer material of the bladder forms the sensor.

International Classification:

A61B 8/00
A61B 8/12
A61B 8/08

Abstract:

The present disclosure is directed to an ultrasonic catheter assembly. More specifically, the catheter assembly includes a catheter and one or more piezoelectric or echogenic components. The catheter has a side wall that extends from a proximal end and a distal end that defines a lumen extending from the proximal end to the distal end. Thus, the lumen is configured to deliver a treatment fluid from the proximal end to the distal end. In addition, the piezoelectric component(s) are configured with the side wall of the catheter and/or embedded at least partially within the side wall of the catheter. As such, the piezoelectric component(s) are configured to enhance ultrasonic imaging of the catheter, e.g. when activated by a stimulator assembly.

International Classification:

A61M 25/00

Abstract:

The present invention is directed to an echogenic member assembly for use with a catheter assembly. The echogenic member assembly includes at least one echogenic member having a cylindrical body extending between a first end and a second end. Thus, the body defines a longitudinal length between the first and second ends. Further, the cylindrical body has an exterior surface extending from the first end to the second end. The exterior surface includes a plurality of discontinuities arranged in a predetermined pattern so as to enhance ultrasonic imaging. In addition, the longitudinal length of the echogenic member is less than a total length of a catheter of the catheter assembly. As such, the echogenic member provides enhanced ultrasonic imaging to the catheter assembly without compromising the inherent flexibility of the catheter.
