Patent attributes
The present teachings provide a device to close a ductus arteriosus percutaneously. One aspect of the present teachings provides a device comprising at least one flange portion configured to be positioned against a vascular wall outside one end of a ductus arteriosus, and a body portion configured to be positioned inside the ductus arteriosus. The body portion of the device has a length adjustable in order for the device to fit inside patients with various ductus arteriosus lengths. The at least one flange portion of the device has pivotability in order for at least one flange to deflect from the longitudinal axis of the body portion so that the deployed device can be positioned at a treatment site allowing the discs to sit flat against the vascular tissue to promote closure while avoiding disruption of flow within the pulmonary artery and aorta or applying excess pressure to the surrounding vascular tissue. The body portion of the device could also at least partially block the ductus arteriosus, and thereby reduce or obstruct blood flow through the ductus arteriosus. The device includes a delivery profile and a deployment profile. Another aspect of the present teachings provides methods of using a device of the present teachings.
