AORTIC OCCLUDER WITH STRENGTH BONDED BALLOONS

摘要

An aortic occluder catheter with expandable balloons for increasing cerebral blood blow has one or more balloons on a catheter shaft. To assist the balloon in bearing up against arterial blood flow while positioned retrograde in the aorta, the balloon is bonded to the catheter shaft using heat shrink tubing and a thermal bonding machine and then further ironed using a second piece of heat shrink tubing and a second heating process.

主权项

1. A catheter, comprising:
an elongate member having proximal and distal ends and proximal and distal regions; at least a first expandable member mounted on the distal region of the elongate member, the first expandable member being inflatable with fluid through at least one lumen in the elongate member to cause the expandable member to expand from an empty configuration to an expanded configuration; and wherein, during use, the flexible distal region allows the elongate member to conform to a portion of the aorta while the first expandable member is positioned in the portion of the aorta and is at least partially expanded to increase cerebral perfusion, wherein the expandable member is attached to the elongate member using a first heat shrink tubing around a neck of the expandable member and then heating at least the first heat shrink tubing and neck, and then the neck ironed after cooling by sliding a second piece of heat shrink tubing over the neck and then heating at least the second heat shrink tubing and neck.
