1. A valve for use during coating of implantable medical devices, the valve comprising:
a distal valve portion, wherein the distal valve portion has an outer shape tapering distally to a distal end including a distal edge having a distal dimension, wherein the distal valve portion defines an internal bore, and wherein the distally tapering outer shape is configured to be inserted into a device bore of an implantable medical device; and
a proximal valve portion coupled to the distal valve portion and including a cap, wherein the proximal valve portion has an outer shape tapering proximally to a proximal end including a proximal edge having a proximal dimension greater than the distal dimension of the distal edge, wherein the cap includes a check valve passage that extends through the cap and that is in communication with the internal bore of the distal valve portion, wherein the internal bore is sized to remain open when a vacuum pressure differential across the valve is above or below an opening pressure differential, and wherein the check valve passage is biased into a closed configuration when the vacuum pressure differential is below the opening pressure differential and transitions into an open configuration in response to the vacuum pressure differential being above the opening pressure differential.
