  • Devices, systems, and methods for treating heart failure
    Patent number: 9775636
    Abstract: The present teachings provide devices and methods for percutaneously removing internal tissue. Specifically, one aspect of the present teachings provides a tissue incising element with a sharp cutting edge and a longitudinal lumen and a tissue stabilizer slidably disposed within the longitudinal lumen of the tissue incising element. The tissue incising element has a deployed configuration during tissue cutting and a small collapsed configuration during the percutaneous delivery and removal. The tissue stabilizer includes a tissue supporting/gripping element configured to support tissue during incising and capture the removed tissue.
    Type: Grant

  • Methods and devices for intra-atrial shunts having adjustable sizes
    Patent number: 9757107
    Abstract: Devices and methods for treating heart disease by normalizing elevated blood pressure in the left and right atria of a heart of a mammal are disclosed. Devices may include an adjustable hydraulic diameter shunt portion which can be manually adjusted in vivo. Methods are provided for adjusting the flow rate of the devices in vivo.

  • Methods and devices for intra-atrial shunts having selectable flow rates
    Patent number: 9642993
    Abstract: Devices and methods for treating heart disease by normalizing elevated blood pressure in the left and right atria of a heart of a mammal are disclosed. The devices are adapted to permit fluid flow across the membrane in which the device is implanted at first rate, and at a second rate, wherein a difference between the first rate and the second rate is not solely dependent upon variations in blood pressure differential across the membrane due to the heart's pumping cycle.
