Patent ID: 8470029

Claim:
A corneal donor disc medical tool, comprising: a holding member with an inner chamber having a wall and a front end; and a flexible substrate configured to slidably retract into the front end of the holding member during a tissue loading operation, wherein the flexible substrate has (i) a substantially flat shape outside the holding member and (ii) a rolled shape when slidably retracted into the inner chamber to a retracted position, wherein the flexible substrate is configured to hold a corneal donor disc during sliding retraction into the inner chamber during the tissue-loading operation, wherein the front end includes at least one retractable cannula, and wherein the tool further comprises a fluid delivery member held inside the holding chamber with a flow path of the fluid delivery member being substantially coaxially aligned with the at least one cannula, and wherein, during implantation, the front end of the tool places a respective corneal donor disc inside an anterior chamber of an eye of a patient while the flexible substrate remains inside the tool and pressurized fluid exits the fluid delivery member and the front end of the holding member to release the corneal donor disc.
