Method for dispensing a polymerizable monomer adhesive
This invention generally relates to a method of dispensing an adhesive material using an applicator comprising: a body having a cavity; at least one breaking member integral with the body and having a surrounding gap, the breaking member deflectable into the cavity and having a first engagement member; an annular housing movable with respect to the body and having a second engagement member complementary with the first engagement member, the first and the second engagement members being cooperatively engageable; a reservoir secured to body and having applicator means; a retaining member between the body and reservoir; and a frangible container of adhesive material disposed within the cavity; moving the annular housing relative to the body from a first position to a second position where the engagement members are cooperatively engaged; deflecting the breaking members and breaking the frangible container; and squeezing the reservoir and dispensing adhesive material.
1. A method of applying/dispensing an adhesive material, the method comprising:
providing an applicator device for dispensing and/or applying an adhesive material, the applicator device comprising:
a body portion comprising a closed proximal end and an open distal end providing a cavity;
at least one breaking member integral with the body portion and each breaking member having a surrounding gap, the at least one breaking member at least partially deflectable into the cavity and each breaking member having a first engagement member;
an annular housing movable with respect to the body portion and having a second engagement member complementary with the at least one first engagement member, the first and the second engagement member being cooperatively engageable with each other;
a reservoir secured to the open distal end of the body portion, the reservoir further having a distal opening comprising applicator means,
a retaining member between the body portion and the reservoir; and
a frangible container of adhesive material disposed within the cavity between the closed proximal end and the retaining member;
moving the annular housing relative to the body portion from a first position where the first and the second engagement member are not cooperatively engaged with each other, to a second position where the first and the second engagement member are cooperatively engaged with each other, deflecting at least a portion of the breaking member into the cavity breaking the frangible container;
squeezing the reservoir providing a positive pressure within the reservoir and
dispensing adhesive material from the reservoir to a substrate;
wherein releasing the squeezed reservoir creates a negative pressure within the reservoir for urging of the adhesive material from the cavity into the reservoir.
2. The method of claim 1 , wherein the substrate is living tissue, a flexible material or mesh.
3. The method of claim 2 , wherein the flexible material or mesh comprises at least one of a medicament, a polymerization initiator or polymerization rate modifier for the adhesive material.
4. The method of claim 2 , wherein the applicator device, the frangible container of adhesive material and/or the adhesive material is sterilized.
