A device for the treatment of venous congestion or venous stasis comprising: a shell having a rim adapted to abut a patient's skin to define a suction area circumscribed by the rim and enclosed by an inner volume of the shell; a conduit supported by the shell and having a delivery tip at a distal end of the conduit the delivery tip including a blunt distal disc-shaped end comprising a microporous material and having a cross-sectional area for dispensing fluid over an area that is larger than a lumen of the conduit, the delivery tip being positionable subcutaneously through an existing incision in the skin and below the rim within the suction area when the shell is positioned against the patient's skin to diffuse an anticoagulant or a thrombolytic agent beneath the skin; and a suction port attached to the shell through which recovered anticoagulant and blood may be drawn from the inner volume.
