Abstract
Devices, kits and tools that facilitate pre-loading, storage, transportation and small incision, partial thickness corneal replacement procedures, including deep lamellar endothelial keratoplasty (DLEK), Descemet's stripping endothelial keratoplasty (DSEK) and Descemet's stripping automated endothelial keratoplasty (DSAEK), using donor eye tissue are provided.
Claims16
A donor corneal tissue storage and delivery device, comprising:
- a housing having a proximal end and a distal end;
- a cannula having a proximal end and a distal end, said cannula disposed at a distal end of the housing;
- a fluid channel connector disposed at a proximal end of the housing;
- at least one fluid channel with a proximal end and a distal end, the proximal end coupled to the fluid channel connector and the distal end disposed within the proximal end of the cannula;
- a flexible support configured to receive a donor corneal tissue and retract into the cannula;
- a retractor shaft coupled to the flexible support;
- one or more loading members held by the housing, coupled to the retractor shaft and operable to retract the retractor shaft and coupled flexible support thereby retracting the flexible support and donor corneal tissue into the cannula;
- a removable reservoir in fluid communication with the fluid channel and configured to enclose the flexible support and cannula and to receive a volume of fluid for hydrating the donor corneal tissue received by the flexible support while the flexible support is retracted into the cannula;
- a deployment shaft coupled to the cannula and configured to retract into the distal end of the housing;
- and
- one or more deployment members coupled to the deployment shaft and operable to cause the deployment shaft to retract the cannula and to deliver the donor corneal tissue to an implantation site from the flexible support retracted into the cannula.

- a fluid channel connector disposed at a proximal end of the housing;
- at least one fluid channel with a proximal end and a distal end, the proximal end coupled to the fluid channel connector and the distal end disposed within the proximal end of the cannula;
- a flexible support configured to receive a donor corneal tissue and retract into the cannula;
- a retractor shaft coupled to the flexible support;
- one or more loading members held by the housing, coupled to the retractor shaft and operable to retract the retractor shaft and coupled flexible support thereby retracting the flexible support and donor corneal tissue into the cannula;

- a deployment shaft coupled to the cannula and configured to retract into the distal end of the housing;
- and
- one or more deployment members coupled to the deployment shaft and operable to cause the deployment shaft to retract the cannula and to deliver the donor corneal tissue to an implantation site from the flexible support retracted into the cannula.
