STENTING DEVICE AND AORTA STENTING KIT Russian patent published in 2020 - IPC A61F2/844 A61F2/90 A61F2/95 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to aorta stenting device and kit, and can be used for hybrid treatment of ascending aortic and aortic arch aneurysms, as well as aortic dissection with open interventions. Stenting device comprises a distal portion for placement with possibility of being engaged in a patient's aortic arch and continuation of a left subclavian artery, being implanted; a stent portion engaged with the fluid transfer with the distal portion, wherein the stent portion is at least partially permeable and configured to overlap a portion of the aortic arch, with which a brachiocephalic trunk is connected, a left common carotid artery and a left subclavian artery; and a proximal portion engaging to transfer fluid thereto. Stenting device is made with possibility of engagement with placing device so that it could be placed in patient's aorta in unfolded configuration, while allowing to vary the diameter and length of the stenting device so as to adapt them to the diameter and length according to the patient's aorta anatomy. Stenting device also includes a flange engaged with the above proximal segment. Flange is made with possibility of selective engagement with aorta and is made of graft material. Aorta stenting kit comprises a placement device and a stenting device according to claim 1, which is engaged with the placing device in the initial configuration. Placing device has a rod capable of translational movement in a patient's aorta and having an end controlled by a surgeon, as well as a distal end; and a first unblocking cable configured to unlock at least one radially restricting element. Said at least one radial-restricting element is configured to limit the diameter of the stenting device. At that, diameter and length of stenting device in unfolded configuration can be changed by means of axial translational movement of rod and unlocking of said at least one radial-restricting element by translational movement of the first unblocking cable.

EFFECT: inventions provide eliminating a false lumen and providing a possibility of healing rupture and cure disintegration.
