Abstract:
1. A method of forming a catheter, the method comprising: providing an elongate shaft including a braided reinforcement member having a proximal end, a distal end and a lumen extending therethrough; disposing an outer layer about at least a portion of the braided reinforcement member, the outer layer having a proximal end and a distal end; wherein disposing an outer layer about at least a portion of the braided reinforcement member includes disposing the outer layer so that the distal end of the outer layer is positioned proximal of the distal end of the reinforcement member; disposing a sleeve having a proximal end and a distal end about a portion of the braided reinforcement member distal of the distal end of the outer layer, the sleeve extending distal of the distal end of the braided reinforcement member; disposing an inflatable balloon having a proximal waist segment and a distal waist segment about a distal portion of the elongate shaft, wherein the distal waist segment is disposed about the sleeve and a portion of the distal waist segment extends distal of the distal end of the sleeve; forming a distal tip with the portion of the distal waist segment extending distal of the distal end of the sleeve; and; wherein a material bonding strength between the inflatable balloon and the sleeve is greater than a material bonding strength between the inflatable balloon and the outer layer.
