Patent ID: 6884232

Claim:
A laparoscopic spray device for mixing and applying a multiple component agent to a target site, comprising: a first fluid reservoir containing a first component and a second fluid reservoir containing a second component; an elongated delivery shaft having a proximal end, a distal end, and at least two fluid delivery channels in fluid communication with the first and second fluid reservoirs, the fluid delivery channels having distal ports; a spray tip assembly having a proximal end, a distal end, and a discharge aperture disposed at the distal end, the spray tip assembly detachably coupled to the distal end of the elongated delivery shaft and having a sealing member disposed at the proximal end of the spray tip assembly that seals the distal ports of the fluid delivery channels of the elongated delivery shaft when the sealing member is in a relaxed state and which allows fluid flow from the distal ports when pressure is applied to the sealing members; an elongated mixing chamber having a proximal end and a distal end, the elongated mixing chamber in fluid communication with the fluid delivery channels when pressure is applied to the first and second components in the fluid delivery channels; at least one lateral port disposed proximally of the distal end of the elongated mixing chamber and in fluid communication with the elongate mixing chamber; and at least one spiral mixing channel proximal to the discharge aperture of the spray to assembly, the at least one spiral mixing chamber in fluid communication with the elongated mixing chamber via the at least one lateral port and in fluid communication with the discharge aperture of the spray tip assembly.
