Abstract:
1. A catheter comprising: an elongate shaft including a reinforcement member having a proximal end and a distal end; an outer layer having a proximal end and a distal end, at least a portion of the outer layer disposed about and permeating into a portion of the reinforcement member, the distal end of the outer layer terminating proximal of the distal end of the reinforcement member such that a distal segment of the reinforcement member is free of the outer layer; a distal extension having a proximal end and a distal end, wherein a portion of the distal extension is disposed circumferentially about a portion of the reinforcement member and secured directly to the distal segment of the reinforcement member such that the distal extension permeates the distal segment of the reinforcement member, the proximal end of the distal extension disposed distal of the distal end of the outer layer; and an inflatable member having a proximal waist section and a distal waist section, the distal waist section secured to the distal extension, wherein a portion of the distal waist section extends distal of the distal end of the distal extension; wherein a material bonding strength between the inflatable member and the distal extension is greater than a material bonding strength between the inflatable member and the outer layer.
