  • Method And Apparatus For Minimizing Excess Drug Delivery
    Publication number: 20240115840
    Abstract: A device and method are described for aspirating within a patient during the delivery of a drug-coated treatment device to help remove drug coating dislodged in a patient's blood. The drug treatment device can be a drug-coated balloon, a drug-coated stent, or similar devices. The device can include an occlusion balloon to help contain the dislodged drug coating and aspiration can be applied proximally, distally, or both proximally and distally of the drug coated balloon during a procedure.

  • Balloon catheter systems
    Patent number: 10874826
    Abstract: A balloon catheter and balloon system particularly useful with drug-coated balloons is described. In some embodiments, the balloon catheter system includes various features designed to address problems with drug rubbing off due to contract friction during delivery of the balloon—including by utilizing a protective sleeve to shield the drug-coated balloon. In some embodiments, the balloon catheter system includes an inner high-pressure balloon and an outer drug-coated balloon to mitigate the time associated with performing vessel dilation.
