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.

International Classification:

A61M 25/10
A61M 25/00

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.

International Classification:

G05B 19/401
G01D 5/14

Abstract:

Systems and methods for calibrating an instrument having a tool and a work surface. An exemplary instrument may comprise a support member including a conductive surface. The instrument also may comprise a fluid-transport device including a conductive tube having an open end. A drive mechanism of the instrument may include a motor operable to drive movement of the surface and the tube relative to one another along an axis and into contact with one another. A circuit of the instrument may include a voltage source and the tube. A control module may be configured to calibrate a relationship between the drive mechanism and a position of the tube and/or surface along the axis based on a sensed change in an electrical property of the circuit that occurs when the tube and the surface contact one another.
