Fan-shaped cannula for sealing ophthalmic incisions

摘要

A device for delivering an incision sealant includes a housing, a seal, and a cannula. The housing at least partially encloses a chamber that holds a quantity of a sealant. The seal is located on one end of the housing and contains the sealant in the chamber. Likewise, a similar seal may be located at the tip end of the fan-shaped cannula. The cannula is fluidly coupled to the chamber, is disposed along an axis, and has a generally fan-shaped end. The generally fan-shaped end has a top surface and an opening for dispensing the sealant. The shape of the generally fan-shaped end is configured to apply sealant to an incision geometry or to conform to the geometry of an eye.

1. A device for delivering an incision sealant comprising:
a housing at least partially enclosing a chamber, the chamber holding a quantity of an ophthalmic sealant; a seal located on one end of the housing, the seal containing the quantity of the sealant in the chamber; and a cannula fluidly coupled to the chamber, the cannula with a generally fan-shaped end, the generally fan-shaped end having a top and bottom surface and an original opening for dispensing the sealant; wherein the opening of the generally fan-shaped end is oblong; wherein the cannula with the generally fan-shaped end further comprises score marks delineating break points along the generally fan-shaped end for modifying the cannula by removing material past the break points; wherein when the generally fan-shaped end is broken along the score marks, a resulting opening has a different size than the original opening.
