Abstract: A variable length balloon catheter assembly and methods for inflating a variable length balloon to a predetermined length. The variable length balloon catheter has a balloon at a distal end and a plurality of stricture mechanisms securing the balloon to the catheter. The stricture mechanisms are provided at known intervals and have a known rupture pressure. The balloon is inflated and a known number of stricture mechanisms are ruptured providing for a variable balloon length based on the number of stricture mechanisms ruptured.

Abstract: An angle assist block for transcutaneous insertion of a needle for a patient is provided. The angle assist block comprises a body portion having an outer surface wherein the outer surface comprises a first side and a second side. The first side is configured to engage skin tissue and the second side opposes the first side. The angle assist block further comprises at least one channel formed through the body portion from the first side to the second side. The channel is angled relative to the first side defining an angle and to allow the needle to be inserted through the channel and transcutaneously introduced at the angle. The angle assist block comprises an attachment portion attached to the outer surface. The attachment portion is configured to removably attach to an attachment receiving member of a tissue visualization device.
