Abstract
A catheter includes a catheter body (CB) having a CB proximal-portion, a CB distal-portion, and a CB lumen. The CB distal-portion has a CB distal end. The CB proximal-portion has a distally narrowing taper, wherein the CB distal-portion extends distally from the distally narrowing taper of the CB proximal-portion. The CB lumen extends through the CB proximal-portion and the CB distal-portion. An ultrasound transmission member (UTM) has a UTM distal end. The UTM extends longitudinally through the CB lumen. The UTM has a longitudinal taper that tapers toward the UTM distal end, and wherein the longitudinal taper tapers distally from the distally narrowing taper of the CB proximal-portion. A distal head (DH) is coupled with the UTM distal end and is disposed adjacent the CB distal end.
Claims20
A catheter, comprising:
- a proximal end connector;
- a catheter body (CB) having a CB proximal-portion extending from the proximal end connector, a CB distal-portion, and a CB lumen, the CB distal-portion having a CB distal end, the CB proximal-portion having a distally narrowing taper, wherein the CB distal-portion extends distally from the distally narrowing taper of the CB proximal-portion, the CB lumen extends through the CB proximal-portion and the CB distal-portion, each of the CB proximal-portion and the CB distal-portion is configured for navigation through a blood vessel;
- an ultrasound transmission member (UTM) having a UTM distal end, the UTM extending longitudinally through the CB lumen, the UTM having a longitudinal taper that tapers toward the UTM distal end, and wherein the longitudinal taper tapers distally from the distally narrowing taper of the CB proximal-portion;
- and
- a distal head (DH) coupled with the UTM distal end and disposed adjacent the CB distal end.
A catheter, comprising:
- a proximal end connector;
- a catheter body (CB) having at least one CB lumen, a a CB proximal-portion extending from the proximal end connector, a CB distal-portion, and a CB distal end, the CB proximal-portion comprising a distally narrowing taper, the CB distal portion extending from the distally narrow taper of the CB proximal-portion;
- and
- an ultrasound transmission member (UTM) extending longitudinally through the at least one CB lumen,
- wherein a CB proximal-portion diameter is from about 0.102 cm to about 0.178 cm and a CB distal-portion diameter is from about 0.076 cm to about 0.127 cm, and a UTM proximal-portion diameter is from about 0.051 cm to about 0.102 cm and a UTM distal-portion diameter is from about 0.013 cm to about 0.038 cm.
