Filed:

Jul 24, 2019

Appl. No.:

17/265377

Inventors:

- NORRISTOWN PA, US
Samuel B. Evans - Blue Bell PA, US

International Classification:

A61F 2/24

Abstract:

A catheter and a method for using the catheter to implant a replacement aortic valve into a patient. The catheter includes an expandable wall, an outer sheath, a first tube operably coupled to the expandable wall, and a second tube operably coupled to the expandable wall. The catheter also includes a pusher that is fixed to the second tube, the pusher being spaced apart from the expandable wall by a distance that is sufficient to accommodate the replacement aortic valve. The outer sheath is movable relative to the expandable wall so that in one state the expandable wall is disposed within the outer sheath and in another state the expandable wall is located outside of the outer sheath. The expandable wall is configured to radially expand. The catheter also includes a handle assembly that is adjusted by a surgeon to achieve the functions of the catheter.

Abstract:

The present disclosure relates to catheter system comprising a balloon and an infusion basket designed to be deployed in complex vasculature to optimally treat vascular and arterial disease conditions such as blood clots, blood emboli, and deep vein thrombosis. The basket may comprise a shaft with a plurality of cuts along a portion of its length to form a plurality of tines that provide support for a plurality of porous tubes to form the limbs of the basket. The limbs of the basket expand radially away from the longitudinal axis of the basket when the longitudinal length of the basket is reduced. The limbs may also be connected to a drug delivery system, and in this manner, baskets of the present disclosure allow for the use of both mechanical and pharmaceutical means of thrombolysis and thrombectomy.
