A mixing and spraying assembly for a tissue sealant includes a mixing assembly, a spray tip assembly, and a malleable section having a proximal end connected with the mixing assembly and a distal end connected with the spray tip assembly for enabling the spray tip assembly to be angulated relative to the mixing assembly. The malleable section includes a flexible shaft having a length, a malleable wire conduit that extends along the length of the flexible shaft, and a malleable wire disposed in the malleable wire conduit. The malleable wire is longer than the flexible shaft and has a proximal end that is connected to the mixing assembly and a distal end that is connected to the spray tip assembly. First and second fluids are mixed within the mixing assembly to form a tissue sealant that is delivered through the malleable section for being expressed from the spray tip assembly.

The present invention relates to surgical instruments and methods for enhancing properties of tissue repaired or joined by surgical staples and, more particularly to surgical instruments and methods designed to enhance the properties of repaired or adjoined tissue at a target surgical site, especially when sealing an anastomosis between adjacent intestinal sections so as to improve tissue viability, prevent tissue infection, and to prevent leakage.

The present invention is directed to devices for mixing and expressing a multi-component sealant or hemostat or adhesive comprising at least two containers configured to contain and express two reactive components into separate lumens of a cannula. An elongated expression tip having a main channel that is open at a proximal end with the cannula slidably fits into the main channel. The tip contains a plurality of separate mixing chambers open at the distal end of the tip, wherein each of the mixing chambers is in fluid communication with the main channel via an individual connecting channel. Openings for each of the connecting channels are provided at different distances from the distal end. The tip is configured to slide on the cannula and advance distally when the main channel is pressurized due to an obstruction in at least one of the mixing chambers.
