Patent ID: 6921381

Claim:
A laparoscopic spray device useful in applying multiple component materials to locations in vivo, comprising: an interface member capable of detachably coupling to a material applicator having at least two material reservoirs storing at least two material components; an elongated body having a first end and a second end, said elongated body having at least two lumens therein, said at least two lumens having a first lumen end in fluid communication with said interface member at said first elongated body end and a second lumen end; a spray tip having a spray tip proximal end and a spray tip distal end, said spray tip detachably coupled to said second elongated body end at said spray tip proximal end, said spray tip comprising: a mixing chamber in communication with said at least two lumens at said second lumen end; a spray aperture at said spray tip distal end; and a spray forming member positioned within said mixing chamber proximate to said spray aperture; and at least one flexible mixing member positioned within said mixing chamber proximate to said second lumen end, said flexible mixing member is configured to flex in response to a force applied by advancing component materials so as to form a narrowing element, and said flexible mixing member is capable of causing impingement mixing of the component materials by forming a turbulent flow within said mixing chamber.
