Device and System for Dispensing a Biological Sealant

A method of delivering a biological material to a delivery site, comprising the steps of:

• a. Providing a device for dispensing a biological material, the device comprising:
• i. a headpiece having proximal and distal ends comprising:
• 1. a first tubular barrel and second tubular barrel, each barrel disposed between the proximal and distal ends of the headpiece for transporting sealant materials, each barrel including an exit port at said distal end of the headpiece;
• 2. a plunger extending into each barrel at said proximal end;
• 3. a pressurized gas conduit disposed between the proximal and distal ends of the headpiece for transporting pressurized fluid, said gas conduit having a gas exit port at the distal end of the headpiece;
• and
• 4. an attachment mechanism located at the distal end of the headpiece;
• ii. an applicator having proximal and distal ends, comprising;
• 1. a mating structure at the proximal end of the applicator, the mating structure configured to be releasably engaged with the attachment mechanism on the headpiece;
• 2. a dispensing structure disposed at the distal end of the applicator;
• 3. a first and second fluid passageway, each fluid passageway being in fluid communication with one of said exit ports and terminating at said dispensing structure;
• 4. a first gas passageway in fluid communication with said gas exit port;
• and
• iii. an actuator located on the headpiece for controlling pressurized fluid flow through the pressurized gas conduit;
• b. at least partially filling said first barrel with a first biological material and at least partially filling said second barrel with a second biological material;
• c. moving each of said plungers in a distal direction so as to force said first biological material from said first barrel through said first fluid passageway and said second biological material from second barrel through said second fluid passageway;
• d. moving said actuator so as to permit the flow of pressurized gas to travel through said gas conduit through said first gas passageway;
• e. atomizing said biological material to form an atomized composition;
• and
• f. dispensing said atomized composition at a predetermined location.

A system for loading a biological sealant into a sealant dispensing device comprising:

• a. a headpiece having proximal and distal ends comprising:
• i. a first tubular barrel and second tubular barrel, each barrel disposed between the proximal and distal ends of the headpiece for transporting sealant materials, each barrel including an exit port at said distal end of the headpiece;
• ii. a plunger extending into each barrel at said proximal end;
• iii. a pressurized gas conduit disposed between the proximal and distal ends of the headpiece for transporting pressurized fluid, said gas conduit having a gas exit port at the distal end of the headpiece;
• and
• iv. an attachment mechanism located at the distal end of the headpiece;
• b. a loader cartridge having a proximal end and a distal end comprising:
• i. an opening at the proximal end;
• ii. a mating structure at the proximal end of said canister structure configured to be releasably engaged with the attachment mechanism of the head piece;
• and
• iii. a plurality of open chambers within said loader cartridge, each open chamber being sized to house a vial in such a fashion that each vial is in fluid communication with one barrel exit port when the loader cartridge is connected to the headpiece.

A method of loading biological sealant components comprising the steps of:

• i. a headpiece having proximal and distal ends comprising:
• 1. a first tubular barrel and second tubular barrel, each barrel disposed between the proximal and distal ends of the headpiece for transporting sealant materials, each barrel including an exit port at said distal end of the headpiece;
• 2. a plunger extending into each barrel at said proximal end;
• 3. a pressurized gas conduit disposed between the proximal and distal ends of the headpiece for transporting pressurized fluid, said gas conduit having a gas exit port at the distal end of the headpiece;
• and
• 4. an attachment mechanism located at the distal end of the headpiece;
• ii. a loader cartridge having a proximal end and a distal end, comprising:
• 1. an opening at the proximal end;
• 2. a mating structure at the proximal end of said canister structure configured to be releasably engaged with the attachment mechanism of the head piece;
• and
• 3. a plurality of open chambers within said loader cartridge, each open chamber being sized to house a vial in such a fashion that each vial is in fluid communication with one barrel exit port when the loader cartridge is connected to the headpiece;
• b. at least partially filling at least two vials with a biological material;
• c. attaching the loader cartridge to the headpiece;
• d. placing said at least two vials within the loading cartridge, such that one vial is placed within one open chamber, such that each exit port is in fluid connection with one of said vials;
• and
• e. drawing the biological material of each vial into the barrel with which it is in fluid connection by withdrawing the plurality of plungers in the proximal direction of the device.
