1. A delivery device for applying two or more drops of a high viscosity surgical adhesive to an anatomical tissue surface, wherein said delivery device comprises:
- (a) an actuator portion comprising an actuator and a push rod, wherein said actuator portion is configured to advance said push rod when a user actuates said actuator,(b) a cartridge housing configured to receive a cartridge containing said high viscosity surgical adhesive, wherein said cartridge housing is attached to said actuator portion such that said push rod is capable of advancing into said cartridge when said cartridge is positioned within said cartridge housing, and(c) a tip releasably engaged to said cartridge housing, wherein said tip comprises two or more channels and two or more tubular members, wherein at least a portion of each of said two or more tubular members is disposed within said channels, wherein at least a portion of at least one of the two or more channels has a non-linear shape, and wherein said tubular members are configured to allow said high viscosity surgical adhesive to move from said cartridge to said anatomical tissue surface when said user actuates said actuator,wherein a single actuation of said actuator is capable of dispensing a single drop of said high viscosity surgical adhesive from a distal tip of each of said tubular members at the same time, wherein the volume of each of said dispensed drops is substantially similar.

11. A delivery device for applying two or more drops of a high viscosity surgical adhesive to an anatomical tissue surface, wherein said delivery device comprises:
-
(a) a push rod, (b) an actuator, wherein said actuator is configured to advance said push rod when a user actuates said actuator, (c) a cartridge housing portion configured to house a cartridge containing said high viscosity surgical adhesive, wherein said push rod is capable of advancing into said cartridge when said cartridge is positioned within said cartridge housing, and (d) a tip located at a distal end of said delivery device, wherein said tip comprises two or more channels and two or more tubular members, wherein at least about 25% of a length of each of said two or more tubular members is disposed within said channels, wherein at least a portion of at least one of the two or more channels is an open channel, and wherein said tubular members are configured to allow said high viscosity surgical adhesive to move from said cartridge to said anatomical tissue surface when said user actuates said actuator, wherein a single actuation of said actuator is capable of dispensing a single drop of said high viscosity surgical adhesive from each of said tubular members at the same time, wherein the volume of each of said dispensed drops is substantially similar. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
