Abstract
Assemblies for storing, handling, transporting, viewing, evaluating, and/or shipping corneal tissue are provided. The assembly includes a corneal tissue carrier, optimized for DSAEK and UT-DSAEK corneal grafts, within a transport vial, the transport vial removably coupled to a stabilization base, wherein the ease of access to the graft carrier allows administering the corneal tissue sample to a patient in rapid succession so that more surgeries can be performed by a single surgeon in a single day.
Claims26
A kit comprising components that together complete a Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK) fitted assembly that provides a corneal graft carrier for supporting and transporting a graft or implant or tissue wherein said kit comprises;
- a vial with a vial lid that includes a poly-cone insert so that said vial lid and a vented cap on said DSAEK fitted assembly compressively secures said DSAEK fitted assembly graft carrier within said vial, a support base that provides support so that said vial is able to stand upright and remain motionless, a collarless luer locking cap, a luer locking connector that includes both a female luer locking end and a barbed male end, wherein said female luer locking end connects with said luer locking cap and wherein said barbed male end is slideably coupled to flexible, nonbeveled tubing, that completes a connection between additional beveled tubing and two glass sections such that one glass section is a corneal tissue graft carrier holding portion that is a non-tapered straight glass tube with a largest opening at a beveled end of said straight glass tube and a second glass section with a spacer portion that provides a rigid connection between beveled flexible tubing and nonbeveled flexible tubing so that a double-flanged glass tube connects to said straight glass tube and luer lock connector and such that said DSAEK assembly provides a graft contained within said complete DSAEK fitted assembly.
A Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK) fitted assembly that is a corneal graft carrier for supporting and transporting a graft or implant or tissue wherein said fitted assembly further comprises a vial with a vial lid that includes a poly-cone insert so that said vial lid and a vented cap on said DSAEK fitted assembly compressively secures said DSAEK fitted assembly graft carrier within said vial, a support base that provides support so that said vial is able to stand upright and remain motionless, a collarless luer locking cap, a luer locking connector that includes both a female luer locking end and a barbed male end, wherein said female luer locking end connects with said luer locking cap and wherein said barbed male end is slideably coupled to flexible, nonbeveled tubing, that completes a connection between additional beveled tubing and two glass sections such that one glass section is a corneal tissue graft carrier holding portion that is a non-tapered straight glass tube with a largest opening at a beveled end of said straight glass tube and a second glass section with a spacer portion that provides a rigid connection between beveled flexible tubing and nonbeveled flexible tubing so that a double-flanged glass tube connects to said straight glass tube and luer lock connector and such that said DSAEK assembly provides a graft contained within said complete DSAEK fitted assembly.
A method for performing tissue repair or replacement surgery that includes utilizing a (DSAEK) fitted assembly within a vial filled with storage media fluid and a graft or implant for supporting and transporting said graft or implant such that when a graft or implant held within said assembly arrives for surgery, a surgeon inspects said graft or implant and said surgeon simply retrieves said fitted assembly that functions as a graft or implant carrier, removes a luer locking cap and attaches a syringe filled with a balanced salt solution (BSS) to a female luer locking connector wherein said fitted assembly includes flexible tubing and an inlet luer-locking mechanism allowing said surgeon quick and simple access to said graft or implant and rapid completion of surgery to replace or repair said tissue.
A method of using a completed DSAEK fitted assembly for supporting and transporting a graft or implant that is a tissue, wherein said DSAEK fitted assembly comprises;
- a vial with a vial lid that includes a poly-cone insert so that said vial lid and a vented cap on said DSAEK fitted assembly compressively secures said DSAEK fitted assembly graft carrier within said vial, a support base that provides support so that said vial is able to stand upright and remain motionless, a collarless luer locking cap, a luer locking connector that includes both a female luer locking end and a barbed male end, wherein said female luer locking end connects with said luer locking cap and wherein said barbed male end is slideably coupled to flexible, nonbeveled tubing, that completes a connection between additional beveled tubing and two glass sections such that one glass section is a corneal tissue graft carrier holding portion that is a non-tapered straight glass tube with a largest opening at a beveled end of said straight glass tube and a second glass section with a spacer portion that provides a rigid connection between beveled flexible tubing and nonbeveled flexible tubing so that a double-flanged glass tube connects to said straight glass tube and luer lock connector and such that said DSAEK assembly provides a graft contained within said complete DSAEK fitted assembly.
