  • Patent number: 8840560
    Abstract: A hand-operated intracardiac echocardiography (ICE) catheter is described for flexed and rotational steering is described for improved catheter operation, control and less trauma on patients. The disclosed catheter assembly includes ultrasound transducers mounted upon a rotatable tip mounted on a distal end of a flexible elongate shaft. A set of steering lines are controlled by a steering actuator to articulate bidirectionally a distal segment of the catheter. Another steering actuator controls rotation of a torque member that, in turn is coupled to the rotatable tip. A user, through the steering actuators, affects repositioning the ultrasonic transducers by repositioning exposed control surfaces of the steering actuators lengthwise along the housing of the handle.

  • Patent number: 8627823
    Abstract: The present invention provides for pleated bags used with interventional pullback systems, including imaging catheters such as IVUS catheters, as well as for use with other catheters. An exemplary pleated bag of the present invention may be an elongate, sterile bag, having a plurality of pleats near the distal end, and including an orifice proximal to the pleats designed to allow passage of a catheter into the bag. The present invention also provides for a system that includes a pullback device, catheter, and pleated bag. The present invention allows for improved imaging catheter procedures at reduced costs.

  • Patent number: 5478331
    Abstract: A multi-function proximal end adapter (70, 86, 100) for a catheter (22) includes a hollow body (6) defining an axial lumen (8) extending between its proximal and distal ends (12, 10). An annular radially compressible seal (48) is positioned within the body along the axial lumen. A seal driver (58) is threadably mounted to the body and has a hollow extension (60) with a distal end adapted to axially compress the seal causing a radially inward deflection of the seal when the seal driver is threaded onto the body thereby providing a good seal against and securement for an object (such as a catheter or guide wire) passing through the axial lumen of the body. At least a portion of the proximal end of the axial lumen is defined by an internal tapered surface (36) sized to matingly and sealingly engage an external tapered surface (44) of a Luer lock connector (40) after the seal driver has been removed from the proximal end of the body.
