    Abstract: The invention relates to restricting flow through a vascular access site such as an arteriovenous (AV) fistula or a graft using intravascular measurements to guide the procedure. The invention provides systems and methods for using intravascular detection to guide the restriction of flow through an AV fistula or graft. An intravascular instrument such as an imaging catheter or guidewire with measuring capabilities is inserted into a vessel proximal to an access site and used to evaluate the access site, which is banded to obtain healthy flow as indicated by the intravascular instrument. In certain aspects, the invention provides a method for improving a hemodialysis fistula or graft by inserting an intravascular instrument into a vessel proximal to the fistula or graft, making a measurement with the intravascular instrument, and restricting flow through the fistula or graft until the measurement obtains a predetermined value.

    Abstract: The invention generally relates to catheter systems and methods for guided formation of vascular access sites (such as fistulas and grafts). According to certain aspects, a catheter system for forming a vascular access site include an elongate body comprising a distal end and configured to be inserted into a first vessel. The elongate body includes an exit port along its side that is proximal to the distal end. An imaging assembly is associated with the elongate body and configured to generate image data of the first vessel and a second vessel positioned next to the first vessel. For vascular access formation, a penetrating member of the catheter system extends out of the exit port and through a wall of the first vessel and a wall of the second vessel.

    Abstract: The invention provides methods and devices for treating liver cirrhosis or portal hypertension by creating an intrahepatic shunt, or new passage, from a portal vein of a patient to a hepatic vein using a device with intravascular imaging capabilities and pressure sensing capabilities or positioning mechanisms. The integration of intravascular imaging aids in the precise placement of the shunt and pressure measurement may verify successful shunt creation. An apparatus may include a catheter with an extended body for insertion into a hepatic vein of a patient, an intravascular imaging device and a needle exit port on the distal portion of the extended body, and a needle disposed within a lumen in the catheter and configured to be pushed out of the exit port and extend away from a side of the extended body, in which the needle includes a pressure sensor.
