Surgical Band Fluid Media Dispenser
First Claim
1. A dispenser for a surgical procedure, comprising:
- a housing containing a volume of flowable material;
a dispensing orifice;
a fluid transfer apparatus operably configured to urge a portion of the volume of flowable material to the dispensing orifice;
a substrate overlying the dispensing orifice having a dispensing opening; and
a substrate transport mechanism operably configured to selectively offset the dispensing opening in the substrate from the dispensing orifice and to align the dispensing opening in the substrate with the dispensing orifice.

Abstract
A multiple use fluid dispenser dispenses a flowable material in a precise pattern and quantity with leaking and clogging between dispensing avoided by employing a trigger fired syringe plunger to expel a fixed volume through a band. Between strokes, an advancement knob rotates the band over a distal dispensing tip to a nondispensing location that wipes excess flowable material and seals a dispensing orifice in a fluid conduit. The advancement knob further may rotate the band to a dispensing position wherein a combination of one or more dispensing holes produce a desired pattern and rate of flow with material over the dispensing hole(s) serving to initiate the flowable material, to control placement, serve as a detachable bandage or buttress material, etc.
