A61M 2900

US Classification:

60410101, 604 401, 60410201

Abstract:

The present invention provides methods, systems and devices for performing cardipulmonary bypass (CPB), cardioplegic arrest, suction of fluid from the aorta to remove embolic or other fluid from the general circulation and the selective segmentation of the arterial system to perform differential perfusion eliminating hypoperfusion. An aortic catheter having an arch lumen which extends at least in part along the length of the catheter shaft has a proximal opening coupled to a CPB machine and a distal arch opening. A corporeal lumen extends at least in part along the length of the catheter shaft and has a proximal opening coupled to a CPB machine and a distal corporeal opening. A suction lumen extends at least in part along the length of the catheter shaft and has a proximal suction opening coupled to a suction source and a distal suction opening residing in the aortic lumen of a patient.

Abstract:

A neurovascular catheter is provided, such as for distal neurovascular access or aspiration. The catheter includes an elongate flexible tubular body, having a proximal end, a distal end and a side wall defining a central lumen. A distal zone of the tubular body includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, an outer jacket surrounding the helical coil, and an opening at the distal end. Adjacent windings of the helical coil are spaced progressively further apart in the distal direction. The opening at the distal end of the tubular body is enlargeable from a first inside diameter for transluminal navigation to a second, larger inside diameter to facilitate aspiration of thrombus into the lumen.

Abstract:

A neurovascular catheter having an elongate flexible tubular body. The body can have a catheter distal face residing on a first plane being at a first nonorthogonal angle relative to the longitudinal axis. The body can have a radiopaque marker being positioned in a distal zone of the tubular body and being proximal to the catheter distal face. The marker can have a marker distal face at least partially residing on a second plane being at a second nonorthogonal angle relative to the longitudinal axis. The first plane can be approximately parallel to the second plane.

Abstract:

A neurovascular catheter having an atraumatic navigational tip is disclosed. The catheter includes an elongate flexible tubular body, a distal zone of the tubular body comprising: a tubular inner liner; a helical coil surrounding the inner liner and having a distal end, a tubular jacket surrounding the helical coil, and extending distally beyond the helical coil distal end to terminate in a catheter distal face, and a tubular radiopaque marker embedded in the tubular jacket. The catheter distal face comprises a first section that resides on a first plane which crosses a longitudinal axis of the tubular body at a first angle within the range of from about 35 degrees to about 55 degrees, and a second section that resides on a second plane which crosses the longitudinal axis of the tubular body at a second angle within the range from about 55 degrees to about 90 degrees.

Abstract:

A neurovascular aspiration catheter has an elliptical distal aspiration port. The catheter has an elongate flexible tubular body comprising a distal port and a side wall defining a central lumen in communication with the port. A tubular radiopaque marker is embedded in the side wall and has a proximal face and a distal face. The distal face of the radiopaque marker inclines at an angle within a range of from about 45 degrees to about 80 degrees relative to the longitudinal axis of the central lumen. The distal port comprises an elliptical opening with an area that is at least about 105% of a cross-sectional area of the central lumen.

Abstract:

A method of making a high flexibility distal zone on a neurovascular catheter is provided. The method includes the steps of dip coating a removable mandrel to form a tubular inner layer on the mandrel, coating the tubular inner layer with a tie layer, applying a helical coil to the outside of the tie layer, positioning a plurality of tubular segments, heating the tubular segments to form the high flexibility distal zone on the neurovascular catheter; and removing the mandrel.
