Abstract
A method for thermal bonding of an inverted balloon neck on a catheter, including placing an inverted balloon neck (84) on a shaft (86) of a catheter, and characterized by applying heat at an internal hollow (85) of the shaft (86) where the inverted balloon neck (84) is placed, while applying internal pressure to attach an external surface of the shaft (86) to the inverted balloon neck (84).
Claims20
A lumen re-entry device, comprising:
- an elongate catheter shaft;
- an inflatable balloon mounted on a distal region of the elongate catheter shaft;
- the elongate catheter shaft including a first lumen in fluid communication with an interior of the inflatable balloon;
- the elongate catheter shaft including an inner surface defining a second lumen having a distal opening positioned proximal of the inflatable balloon;
- and
- an elongate member directly facing the inner surface of the second lumen with no intervening structure therebetween, the elongate member being slidably extendable through the second lumen to extend in a direction parallel to a longitudinal axis of the elongate catheter shaft as the elongate member exits out the distal opening of the second lumen and extends alongside a proximal neck of the inflatable balloon when the inflatable balloon is inflated;
- wherein a body portion of the inflatable balloon is configured to deflect a distal end portion of the elongate member upon inflation of the inflatable balloon.

A lumen re-entry device, comprising:
- an elongate catheter shaft having a first lumen and a second lumen;
- an inflatable balloon having a proximal neck mounted on a distal region of the elongate catheter shaft;
- the first lumen being in fluid communication with an interior of the inflatable balloon and the second lumen having a distal opening located proximal of the inflatable balloon;
- and
- an elongate member slidable relative to the elongate catheter shaft, the elongate member configured to extend from the distal opening of the second lumen in a direction parallel to a longitudinal axis of the elongate catheter shaft alongside the proximal neck of the inflatable balloon when the inflatable balloon is inflated, the elongate member configured to be positionable exterior of and in direct contact with a proximal conical outer surface of the inflatable balloon;
- wherein the inflatable balloon is configured to deflect a distal end portion of the elongate member upon inflation of the inflatable balloon.
