Abstract: Devices and methods for providing a reservoir of fluid within a handle of a guide catheter are disclosed. As one example, a delivery apparatus can include a handle including a proximal segment including one or more fluid seals mounted within the proximal segment, an intermediate segment disposed adjacent and distal to the proximal segment, the intermediate segment including an inner surface defining a first lumen having a first inner diameter, and a distal segment disposed adjacent and distal to the intermediate segment. The delivery apparatus can further include a shaft extending distally from the handle, the shaft including a second lumen extending between a distal end and a proximal end of the shaft, the second lumen including a second inner diameter that is smaller than the first inner diameter of the first lumen.

Abstract: Devices and methods for providing fluid to a lumen of a guide catheter with a fluid reservoir fluidly coupled to the lumen, such that pressure within the lumen is maintained at a desired level, are disclosed. As one example, a delivery apparatus can include a handle, a shaft extending within and distally from the handle and having a main lumen, and a reservoir fluidly coupled to the main lumen. The reservoir is filled with fluid and has an adjustable fluid volume, and the reservoir is configured to passively supply fluid to the main lumen based on a fluid pressure in the main lumen.
