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.
Claims14
An echogenic catheter assembly, comprising:
- a catheter comprising a proximal end and a distal end and defining a lumen extending from the proximal end to the distal end;
- and
- a coil member arranged with at least a portion of the lumen of the catheter, the coil member forming a plurality of outwardly extending projections, each of the plurality of outwardly extending projections defining a cross-sectional shape comprising a combination of a triangle having a non-arcuate edge and at least one of an ellipse or a quadrilateral, each of the non-arcuate edges defining a vertex at which two sides of one of the cross-sectional shapes intersect at an outermost point of one of the cross-sectional shapes, the non-arcuate edges of the plurality of outwardly extending projections configured to enhance ultrasonic imaging of the catheter when inserted into a patient.
An echogenic coil member assembly for a catheter, comprising:
- at least one coil member capable of being arranged within a lumen of the catheter, the coil member comprising a plurality of outwardly extending projections, each of the plurality of outwardly extending projections defining a cross-sectional shape comprising a combination of a triangle having a non-arcuate edge and at least one of an ellipse or a quadrilateral, each of the non-arcuate edges defining a vertex at which two sides of one of the cross-sectional shapes intersect at an outermost point of one of the cross-sectional shapes, the non-arcuate edges of the plurality of outwardly extending projections configured to enhance ultrasonic imaging of the catheter when inserted into a patient.
