  • Dilation catheter structure
    Publication number: 20040092869
    Abstract: A dilation catheter structure of the rapid exchange is provided with an inflatable balloon and with a lumen for a guide thread. The catheter comprises a distal tube (12) and a guide tube (13). The guide tube (13) extends into the distal tube (12), and the proximal ends (13′, 12′) of the guide tube (13) and the distal tube (12) are joined to one another and at the distal end (11′) of the main tube (11). The proximal end (13′) of the guide tube (13) has an opening on one side of the main tube (11) and the proximal end (12′) of the distal tube (12) reaches the distal end of the main tube and the proximal end of the guide tube tightly and simultaneously.

  • Dilating catheter for the introduction of expandable stents
    Patent number: 6007545
    Abstract: A dilating catheter is provided for introducing and inserting an expandable stent. The dilating catheter includes an inflatable balloon, which is applied on a distal section of said catheter and which can be wrapped, if empty, on the section in order to be applied there around a the contracted stent. The outer surface of the balloon is roughened by means of a supply of material or a deformation in order to offer greater interference and grip to the said stent contracted tightly around it.

  • System for introducing and positioning expandable stents
    Patent number: 5971990
    Abstract: A catheter structure is provided for dilating and for positioning stents. The catheter structure includes a catheter having an inflatable balloon. Two collars are fixed around a catheter part inside the balloon and intended to define two annular shoulders one in front of the other and spaced apart in parallel. A tubular adapter is arranged around the catheter portion between the collar. The balloon, when empty, is wrapped around the collars with the tubular adapter comprised between same. The shoulders form bilateral axial closing means for a stent that is arranged and contracted around the empty and wrapped balloon.
