Embodiment Construction

[0024] The present invention provides an optically transparent device that can be used for rapid and precise microscopic studies of quality control and ensuring the integrity of tissue grafts or grafts and / or implants during processing and prior to introduction into a living body. Proper orientation ("top and bottom") of the graft or implant during transport and / or storage and / or storage. The device according to the invention is suitable for securely supporting tissue grafts or implants during evaluation, storage and / or transport. Suitable tissue grafts or implants are eg DMEK, PDEK and ultrathin- / nanothin-DSEK / DSAEK grafts, or related grafts or implants. In particular, the present invention has significant benefits for the treatment of "endothelium-in" / "tri-fold" corneal grafts or implants.

[0025] The engineered properties of the device allow microscopic analysis of the implant as well as fixed orientation during preparation, evaluation, storage, transport and implantation...

Abstract

The present invention provides a device for reliable support and / or transport of tissue grafts or implants that allows for precise microscopical study and / or evaluation and quality control of tissue grafts or implants during treatment and prior to introduction into a living body. The body of the device is a sleeve or shell comprising a rectangular shape preferably having a circular edge and having two opposite openings of different sizes and shapes. The first opening is circular having a diameter suitable for connection to a tube or syringe nozzle. The second opening has an elliptical, circular, biconvex or rectangular shape, preferably with a circular edge in the case of a rectangular shape, the shape of the second opening being small enough to be inserted into a small surgical incision. The transparency and preferably circular, rectangular shape of the device body allows microscopy of tissue grafts or implants within the device and fixation of the location of the tissue grafts or implants during delivery and implantation. The elliptical, circular, biconvex, or preferably rounded rectangular internal shape of the second opening ensures proper positioning of the tissue graft or implant during surgical implantation, thereby preventing issues such as loss of orientation of the tissue graft or implant. The invention also provides an assembly for loading, storing and / or transporting a tissue graft or implant comprising a device according to the invention. The invention also provides a cleaning assembly and a method for preparing a tissue graft or implant.

Description

technical field [0001] The present invention provides a device for reliable support and / or transport of tissue grafts or implants that allows precise microscopic studies and / or Evaluation and Quality Control. The body of the device is a sleeve or tube comprising a rectangular shape, preferably with rounded edges, with two opposing openings of different size and shape. The first opening is circular with a diameter suitable for connection to a tube or syringe nozzle. The second opening has an oval, circular, lenticular or rectangular shape, preferably with rounded edges in the case of a rectangular shape, the shape of the second opening being small enough to be inserted into a small surgical incision. The transparency and preferably circular, rectangular shape of the device body allows microscopic inspection of the tissue graft or implant within the device, as well as securing the position of the tissue graft or implant during delivery and implantation. The elliptical, circul...
