Abstract
An intracatheter pump apparatus and method is described for infusing fluids through a lumen of a catheter. The intracatheter pump includes a motor or power source on the outside of the catheter which causes movement of a fluid moving mechanism positioned in the lumen of the catheter, the fluid moving mechanism being attached to the distal end of an elongated member which in turn is attached to the motor.
Claims15
An intracatheter perfusion pump apparatus for pumping fluids into and out of a lumen of a catheter, the pump apparatus being sized to fit within a coronary artery, comprising:
- an elongated member having a proximal end and a distal end and being positionable in the lumen of the catheter,
- a motor mechanically connectable to the proximal end of the elongated member for moving the elongated member, and
- a fluid moving mechanism attached to the elongated member proximate the distal end thereof, movement of the fluid moving mechanism causing longitudinal movement of fluids through the lumen.
A system for localized perfusion of fluids, comprising:
- a catheter having at least one lumen, the lumen having at least two longitudinally spaced-apart fluid communication ports;
- an elongated member having a proximal end and a distal end and being positionable in the lumen of the catheter;
- a motor mechanically connectable to the proximal end of the elongated member for moving the elongated member;
- and a fluid-moving mechanism attached to the elongated member proximate the distal end thereof, movement of the fluid-moving mechanism causing localized fluid flow within the lumen of the catheter between the spaced-apart fluid communication ports, the catheter, elongated member and motor sized to fit within the coronary artery.
A pump apparatus for pumping fluids into and out of a lumen of a catheter, comprising:
- an elongated member having a proximal end and a distal end positionable in the catheter,
- power means mechanically connectable to the proximal end of the elongated member for imparting longitudinal reciprocating motion, and
- a fluid moving mechanism positioned proximate the distal end of the elongated member for moving fluids upon longitudinal reciprocating movement thereof by the power means.
A method, of pumping fluids through a section of a catheter lumen disposed in a coronary artery, the lumen having at least two longitudinally spaced apart fluid communication ports, the method comprising the steps of:
- inserting .an elongated member, having a fluid moving mechanism attached to a distal end thereof, into the lumen of the catheter in the coronary artery;
- and
- moving the elongated member such that the fluid moving mechanism moves fluid longitudinally of the lumen between the two longitudinally spaced apart ports within the coronary artery.
A system for localizing perfusion of fluids, comprising:
- a catheter having at least one lumen, the lumen having at least two longitudinally spaced-apart fluid communication ports;
- an elongated member having a proximal end and a distal end and being positionable in the lumen of the catheter;
- a motor mechanically connectable to the proximal end of the elongated member for moving the elongated member;
- and
- a fluid-moving mechanism attached to the elongated member proximate the distal end thereof, movement of the fluid-moving mechanism causing localized fluid flow within the lumen of the catheter between the spaced-apart fluid communication ports, the catheter, elongated member and motor sized to fit within the coronary artery.
