Abstract
A catheter useful for improving blood flow to a patient's heart has an elongated catheter body with a proximal end and a distal end. The elongated catheter body defines a catheter lumen. The elongated catheter body has an introducer distal portion with a tissue piercing distal end. An ultrasound transducer is positioned in the introducer distal portion.
Claims53
A catheter, comprising:
- an elongated catheter body with a proximal end and a distal end, the elongated catheter body defining a catheter lumen, the elongated catheter body including an introducer distal portion with a tissue piercing distal end;
- and
- an ultrasound transducer positioned in the introducer distal portion.
A catheter system, comprising:
- a guiding catheter including an elongated guiding catheter body defining a guiding catheter lumen;
- and
- a delivery catheter positionable in the guiding catheter lumen, the delivery catheter including an elongated delivery catheter body, an introducer distal portion with a tissue piercing distal end, and an ultrasound transducer coupled to the introducer distal portion.
A catheter, comprising:
- an elongated catheter body defining a lumen, the elongated catheter body including a distal portion and a longitudinal axis along the distal portion;
- a tissue piercing member coupled to the elongated catheter body and laterally extendable from the distal portion relative to the longitudinal axis, the tissue piercing member including a tissue piercing distal end;
- and
- an ultrasound transducer coupled to the tissue piercing member.
