  • Patent number: 9278015
    Abstract: A catheter system and method are described for stenting a vessel at a bifurcation or sidebranch of the vessel. The catheter system includes a first balloon catheter, a second balloon catheter and a releasable linking device for holding the first and second balloon catheters arranged in a side-by-side configuration and aligned with one another along a longitudinal axis so that the catheter system can be advanced as a unit. The catheter system is combined with drug eluting technology to prevent restenosis, inflammation and/or thrombosis and/or to promote reendothelialization in the vessel bifurcation. The main vessel stent and/or the sidebranch stent may be coated or impregnated with one or more drugs or bioactive substances. Alternatively or in addition, the first balloon and/or the second balloon may be coated with or include a mechanism for delivering one or more drugs or bioactive substances to the vessel wall.

  • Patent number: 8814925
    Abstract: A catheter system including: a stent delivery catheter (2) having a proximal end and a distal end and an interior lumen extending between the proximal end and the distal end; a stent (1) having a proximal end and a distal end and a stent lumen extending between the proximal end and the distal end, the stent having an expanded state and an unexpanded state; and an embolic protection filter (3) having an expanded state and an unexpanded state; the catheter system having a deployed position and an undeployed position. When the catheter system is in the undeployed position, the stent (1) is in its unexpanded state and positioned within the interior lumen of the stent delivery catheter (2) and the embolic protection filter (3) is in its unexpanded state and positioned within the stent lumen of the stent.

  • Patent number: 8808359
    Abstract: A catheter system and method are described for stenting a vessel at a bifurcation or sidebranch of the vessel. The catheter system includes a first balloon catheter, a second balloon catheter and a releasable linking device for holding the first and second balloon catheters arranged in a side-by-side configuration and aligned with one another along a longitudinal axis. The linking device allows the catheter system to be advanced as a unit and helps prevent premature or inadvertent dislodgement of the stent from the catheters, yet is releasable so that one or both of the balloon catheters can be released from the linking device and maneuvered separately from the rest of the catheter system when desired. The method utilizes the described catheter system for stenting bifurcated vessels using a modified “kissing balloons” technique.

  • Patent number: 7645296
    Abstract: A catheter system is described for performing protected angioplasty and stenting of a patient's carotid bifurcation. A self-expanding stent is deployed across a stenosis in the patient's carotid artery. A catheter system that includes a rapid exchange angioplasty catheter with an occlusion balloon catheter positioned through the guidewire lumen is advanced through the guiding catheter to the distal end of the stent. A releasable linking device holds the catheter system together as a unit. The occlusion balloon is inflated within the stent to occlude the carotid artery and to prevent any embolic debris from traveling downstream from the treatment site. The angioplasty balloon is inflated to dilate the stenosis and to complete the expansion of the stent. The angioplasty catheter is withdrawn and any potential embolic debris is aspirated out through the lumen of the guiding catheter. The occlusion balloon is deflated and the catheter system is withdrawn.
