  • Balloon catheter for stent delivery having microchannels and method
    Patent number: 6464718
    Abstract: A balloon catheter and stent delivery system for medical treatment of a patient includes a balloon inflatable to an inflated shape having a cylindrical working portion, and a deflated shape that is temporarily reformed to enhance longitudinal retention of the stent while the catheter system is advanced or withdrawn. The balloon catheter provides for uniform expansion of the stent when the balloon is inflated. In addition, the balloon catheter system can be modified to initiate partial inflation of the proximal and distal ends of the stent, to further resist longitudinal motion of the stent during inflation, and to facilitate more effective tacking of the stent. One possible feature of the catheter system is that the balloon is pleated in a particular pattern when deflated, whereby the central balloon portion carrying the stent has a greater number of pleats than the pillow portions proximal and distal of the stent.

  • Balloon catheter with elongated flexible tip
    Patent number: 6402720
    Abstract: A balloon catheter is provided which has a long, atraumatic tip positioned distally of the balloon. The distal edge of the tip has an annular chamfer. The balloon catheter typically is of a variety having a relatively stiff distal end or balloon assembly, and the atraumatic tip enhances tracking of such balloons along a thinner guidewire.

  • Method for making a balloon catheter stent deployment system
    Patent number: 6289568
    Abstract: A balloon catheter and stent delivery system for medical treatment of a patient includes a balloon inflatable to an inflated shape having a cylindrical working portion, and a deflated shape that is temporarily reformed to enhance longitudinal retention of the stent while the catheter system is advanced or withdrawn. The balloon catheter provides for uniform expansion of the stent when the balloon is inflated. In addition, the balloon catheter system can be modified to initiate partial inflation of the proximal and distal ends of the stent, to further resist longitudinal motion of the stent during inflation, and to facilitate more effective tacking of the stent. One possible feature of the catheter system is that the balloon is pleated in a particular pattern when deflated, whereby the central balloon portion carrying the stent has a greater number of pleats than the shoulder portions proximal and distal of the stent.
