Claim Text:
1. A microfluidic delivery device comprising: a reservoir that forms a hollow body with an opening, the reservoir having a reservoir volume; a transport member having a first end portion and a second end portion, wherein at least a portion of the first end portion of the transport member is in fluid communication with the reservoir, and wherein the transport member has a transport member volume; an enclosure at least partly closing the opening of the reservoir; a microfluidic delivery member comprising a microfluidic die, the microfluidic die having a fluid chamber in fluid communication with at least a portion of the second end portion of the transport member at an inlet of the fluid chamber, the microfluidic die also including a nozzle at an outlet of the fluid chamber; and an adapter disposed adjacent at least a portion of the second end portion of the transport member, the adapter having a wall that forms a cavity for receiving the second end portion of the transport member, wherein a capillary passage is formed at an interface between the wall of the adapter and the second end portion of the transport member, wherein the capillary passage has a largest effective pore size and wherein the transport member has an average effective pore size, and wherein the largest effective pore size of the capillary passage is smaller than the average effective pore size of the transport member, wherein the transport member volume is less than 60% of the reservoir volume.
