Abstract
A wetting device includes absorbent material for wetting the hydrophilic coating of a medical guide wire, catheter, or other medical instrument to minimize friction and to facilitate passage of such medical instrument into a patient's body or through another medical instrument. The absorbent material of the wetting device includes a central bore through which a medical instrument is threaded. The absorbent material is supported proximate the point where friction would otherwise result when the hydrophilic coating begins to dry. The absorbent material is wetted, and is preferably made of a deformable, resilient material, allowing the user to squeeze wetting fluid from the absorbent material onto the hydrophilic coating passing therethrough. A porous liner may be included to prevent physical contact between such absorbent material and the medical instrument. The wetting device may include a slit communicating with the central bore to aid in removal of the device after use.
