Abstract
A catheter apparatus includes an elongate hollow tubular body portion with multiple side holes a sealing member on its distal end for preventing flow from the distal end. All flow is thereby directed through the multiple side holes. The sealing member is designed to be punctured or selectively opened by a guide wire if the need arises. The tip sealing member is further design to 'reseal' if it becomes necessary to perforate the seal. This 'resealing' greatly reduces the end flow and encourages lateral flow through the multiple side holes.
