Corneal Transplant Systems, Methods, and Apparatuses
A transplant tissue storage, transport, and/or placement apparatus, including at least some of a transplant device extending from a distal portion to a proximal portion; a tissue support element formed in the distal portion, the tissue support element having an upper surface having a tissue support element configured to support a central portion of transplant tissue, and a transplant tissue securing mechanism with opposing first securing pad and the second securing pad configured for clasping opposing peripheral portions of transplant tissue in a draped configuration; and a lockable arrangement formed in the proximal portion, the lockable arrangement configured to release a secured transplant tissue from the mounting surface, upon actuation.
SYSTEMS AND METHODS FOR TISSUE DISSECTION IN CORNEAL TRANSPLANTS
A dissection system for corneal transplants includes a housing including a contact side to be positioned against a cornea. The housing includes an interior passageway with an opening at the contact side. The dissection system includes a blade assembly disposed in the interior passageway. The blade assembly includes a first blade and a second blade. The first blade includes a first cutting edge and the second blade includes a second cutting edge. The first blade and the second blade are movable relative to the housing such that the first cutting edge and the second cutting edge extend through the opening of the housing and out of the interior passageway. The first cutting edge produces a first cut in the cornea. The second cutting edge produces a second cut in the cornea. The first cut and the second cut define a volume of tissue for removal from the cornea.
SCLERAL PROSTHESIS FOR TREATING PRESBYOPIA AND OTHER EYE DISORDERS AND RELATED DEVICES AND METHODS
An implantation device includes an elongated tube having a first end portion, an opposing second end portion, and a third tapered portion connecting the first and second end portions. The first end portion includes a first opening and an angled tip. The second end portion includes a second opening, and the second end portion is wider than the first end portion. The implantation device also includes a rod inserted through the first opening and extending out of and away from the first end portion. The rod includes a tapered and rounded end. The second end portion is configured to receive a scleral prosthesis into the second opening and to release the scleral prosthesis from the second opening.
CORNEAL DEVICE INSERTERS AND METHODS OF USE
Corneal device inserters and positioners that include an elongate member with a distal region, the distal region including a top portion, a bottom portion, and a corneal device receiving space, the corneal device receiving space defined by the top portion, the bottom portion, and a receiving space proximal end, the distal region further comprising a slot in fluid communication with the corneal device receiving space, the slot extending through at least one of the top portion and the bottom portion, the slot having a slot proximal end disposed at least as far proximally as the receiving space proximal end.
Intraocular lens inserter and system and method regarding same
An inserter, system and method for inserting an IOL may include a lumen having an outer wall and an inner wall that includes at least one hollowed portion; a plunger for advancing along the lumen and having a plunger shaft extending into an open proximal end and terminating at a distal plunger end; a reservoir within the lumen between the distal plunger end and the distal insertion tip, having an opening that is misaligned with the at least one hollowed portion prior to advancing of the plunger, and that is aligned with the at least one hollowed portion during advancing of the plunger; and a viscous fluid within the lumen that flows along a bypass formed of the at least one hollowed portion and the opening and into the reservoir, decreasing an inserting displacement force effected at the distal insertion tip from a plunger displacement force applied to said plunger.
CORNEA POSITIONING SYSTEM AND POSITIONING METHOD
A cornea positioning system includes: a mechanical arm assembly, an image recognition system, a background assembly arranged opposite to the image recognition system, and a calculation positioning system connected to the image recognition system. The mechanical arm assembly is configured to move a corneal package body containing a cornea to-be-positioned to be between the image recognition system and the background assembly. The background assembly is configured to provide background light. The image recognition system is configured to obtain an image formed under action of the background light of cornea packaging body. The computing positioning system is configured to analyze and calculate the image obtained by the image recognition system acquire position information about the cornea.
Device and system for injecting biological tissue
A device, kit, and method for aspirating graft tissue and delivering the graft tissue to a target delivery site. An injector comprises a cylinder and a plunger that is both linearly and rotatably advanceable and retractable within the cylinder. A kit comprises an injector, a cartridge, and a cartridge coupling element that connects the cartridge to the injector. The kit may also include a container that is configured to retain a cartridge and to facilitate connection between the injector and the cartridge. The container includes at least one fluid barrier that prevents spillage of storage solution from the container when the injector is at least partially inserted into the well of the container.
CORNEAL IMPLANTS AND METHODS AND SYSTEMS FOR PLACEMENT
A system comprising a hollow member is used to deliver a constrained corneal implant into a corneal pocket. The hollow member may be tapered and the system may further include an implant deformation chamber and an axial pusher to advance the implant through the hollow member.
DEVICES AND METHODS FOR IMPLANTING CORNEAL TISSUE
A device for manipulating an implant includes a handle coupled to a guide extending from the handle to a distal end. The device includes an engagement mechanism disposed at the distal end of the guide and configured to engage an implant. The device includes a first actuator disposed on the handle and coupled to the engagement mechanism. The first actuator causes the engagement mechanism to engage the implant. The device includes an air chamber disposed in an interior chamber of the handle and configured to hold air. The device includes a lumen coupled to the air chamber and extending along the guide to the distal end. The lumen includes an air channel extending through the lumen. The device includes a second actuator disposed on the handle. The second actuator causes the air chamber to deliver the air, via the air channel, to the distal end.
Ocular implant insertion apparatus and methods
An exemplary ocular implant insertion system includes a case and a preloaded ocular implant insertion apparatus. The apparatus includes first and second movable structures that move the ocular implant in a predetermined sequence. The respective configurations of the case and the ocular implant insertion apparatus are such that the ocular implant insertion apparatus is not removable from the case when the ocular implant insertion apparatus is in the pre-use state and is removable after the first movable structure has moved at least a portion of the optical implant.
