Method and devices for implantation of biologic constructs
Seal systems and devices for delivering a biologic construct repair for shoulder and joint surgery into an arthroscopic workspace, including a pinch to open seal that uses fluid pressure to self-seal against a curved surface when closed.
1. A seal system for use with an arthroscopic instrument comprising:
a seal having a first section with a top face, the top face having a central inwardly curved or parabola shape that curves towards a slit in the top face, said slit characterized by a longitudinal axis, said seal having a second section integrally formed with the first section, said second section having a narrower outer diameter than the first section; and
a cannula for conducting fluid therethrough, said cannula having a proximal end;
said seal second section releasably attached to the cannula proximal end; and
wherein the seal first section is moveable from a first closed configuration to a second open configuration said seal operable to attain said open configuration upon application of compressive force along the longitudinal axis of the slit, and operable to revert to the closed configuration upon removal of said compressive force.
2. The seal system of claim 1 further including a circular wiper seal.
3. The seal system of claim 1 wherein the top face is in the shape of an ellipse, wherein the slit is aligned along a major axis of the ellipse.
4. The seal system of claim 1 wherein the top face is in the shape of an oval, wherein the slit is aligned along a major axis of the oval.
5. The seal of claim 4 further including a circular wiper seal.
6. The seal of claim 4 wherein the top face is in the shape of an ellipse, wherein the slit is aligned along a major axis of the ellipse.
7. The seal of claim 4 wherein the top face is in the shape of an oval, wherein the slit is aligned along a major axis of the oval.
8. The seal system of claim 1 wherein the seal is hollow.
9. The seal system of claim 1 wherein the first section has an inner diameter and wherein the second section has an inner diameter, wherein the second section inner diameter is narrower than the first section inner diameter.
10. A seal for use with a cannula, said seal comprising:
a seal having a first section with a top face, the top face having a central inwardly curved or parabola shape that curves towards a slit in the top face, said slit characterized by a longitudinal axis, said seal having a second section integrally formed with the first section, said second section having a narrower outer diameter than the first section; and
wherein the seal first section is moveable from a first closed configuration to a second open configuration said seal operable to attain said open configuration upon application of compressive force along the longitudinal axis of the slit, and operable to revert to the closed configuration upon removal of said compressive force.
11. The seal of claim 10 wherein the seal is hollow.
12. The seal of claim 10 wherein the first section has an inner diameter and wherein the second section has an inner diameter, wherein the second section inner diameter is narrower than the first section inner diameter.
