The present invention relates to an angiographic catheter package consisting of a sterilizable envelope pouch, an elongate tray and a catheter tip restraint which releasably retains the catheter tip therein in the desired performed shape. The tip restraint securely holds the catheter tip in the desired shape during sterilization and storage of the catheter and yet readily releases the catheter tip from the tip restraint when the user desires to remove the catheter from the sterile package.

Angiographic catheter package

An improved non-whip angiographic catheter has a preselected number of openings of preselected size, location and orientation along the straight portion of the catheter near the distal tip so as to distribute the force of the high-pressure dye injection jets while maintaining the non-whip characteristic. At least one opening in the catheter long portion is provided facing the open end of the tip portion so that the dye trajectories from the catheter tip opening and the catheter long portion opening are generally coplanar and perpendicular so as to interfere with each other for improved dye dispersion. At least two reaction openings of predetermined size are provided on the opposite side of the catheter long portion at preselected locations, the dye trajectories of these three reaction openings also being generally coplanar with the trajectories of the first opening and the open end of the catheter tip. The special openings have sufficiently small diameters and are specially staggered so as to reduce the possibility of kinking the catheter during placement of the catheter into position for diagnostic angiography.
