前記ノーズコーンの前記遠位端領域から延びる遠位シャフトであって、当該遠位シャフトは、当該遠位シャフトの近位端領域から遠位端領域までの管腔を画定し、当該遠位シャフトの少なくとも前記遠位端領域は、眼の前眼房に挿入するためのサイズおよび形状を有する遠位シャフトと、を備える組織カートリッジと、
前記ノーズコーンの前記近位端領域と係合するとともに可逆的に結合するように寸法構成された遠位端領域を有する近位ハンドルを備える送達デバイスと、を備えるシステム。 1. A system for preparing and inserting an implant into a patient's eye, the system comprising:
1. A tissue cartridge comprising:
a nosecone including a proximal end region and a distal end region;
a tissue cartridge comprising: a distal shaft extending from the distal end region of the nosecone, the distal shaft defining a lumen from a proximal end region to a distal end region of the distal shaft, at least the distal end region of the distal shaft being sized and shaped for insertion into an anterior chamber of an eye;
a delivery device comprising a proximal handle having a distal end region dimensioned to engage and reversibly couple with the proximal end region of the nosecone. 前記近位端領域と前記遠位端領域との間の可逆的結合は、雄－雌の接続を備える、請求項１に記載のシステム。 The system of claim 1, wherein the reversible coupling between the proximal end region and the distal end region comprises a male-female connection. 切断デバイスをさらに備え、当該切断デバイスが、生物由来の物質のパッチを前記移植体に切断するように構成された切断部材を備える、請求項１に記載のシステム。 The system of claim 1, further comprising a cutting device, the cutting device comprising a cutting member configured to cut the patch of biological material into the implant. 前記切断部材は、少なくとも第１の刃を備える、請求項３に記載のシステム。 The system of claim 3, wherein the cutting member comprises at least a first blade. 前記切断部材は、前記第１の刃から距離を隔てた第２の刃を備える、請求項４に記載のシステム。 The system of claim 4, wherein the cutting member comprises a second blade spaced a distance from the first blade. 前記切断部材の作動により、前記第１の刃および前記第２の刃が、前記移植体を形成する前記物質の前記パッチの厚さに向けて付勢されるとともに当該厚さで切断されて、前記距離が前記移植体の幅に等しい、請求項５に記載のシステム。 The system of claim 5, wherein actuation of the cutting member urges the first blade and the second blade toward and cuts through a thickness of the patch of material forming the implant, the distance being equal to a width of the implant. 前記切断デバイスは、前記切断部材を作動させるように構成されたベースに移動可能に結合されたハンドルをさらに備える、請求項３に記載のシステム。 The system of claim 3, wherein the cutting device further comprises a handle movably coupled to a base configured to actuate the cutting member. 前記生物由来の物質は、採取または工学的処理された組織、臓器、または臓器の一部である、請求項３に記載のシステム。 The system of claim 3, wherein the biological material is a harvested or engineered tissue, organ, or organ part. 前記組織は、自家移植片、同種移植片、または異種移植片物質である、請求項３に記載のシステム。 The system of claim 3, wherein the tissue is autograft, allograft, or xenograft material. 前記生物由来の材料は、眼内に前記移植体を配置した後に実質的に吸収され、いったん吸収されると、前記移植体が配置された場所に空間が残る、請求項３に記載のシステム。 The system of claim 3, wherein the biological material is substantially absorbed after placement of the implant in the eye, and once absorbed, leaves a space where the implant was placed. 前記送達デバイスは、前記遠位シャフトの前記管腔の内部に配置された移植体を遠位開口部から眼内に展開するように構成された少なくとも１つのアクチュエータをさらに備える、請求項１に記載のシステム。 The system of claim 1, wherein the delivery device further comprises at least one actuator configured to deploy an implant disposed within the lumen of the distal shaft through a distal opening into the eye. 前記少なくとも１つのアクチュエータは、ツールが引っ込んだ第１の位置から、前記管腔の内部に配置された前記移植体の後方で前記ツールが前記管腔の内部に挿入する第２の位置まで前記ツールを前進させるように構成される、請求項１１に記載のシステム。 The system of claim 11, wherein the at least one actuator is configured to advance the tool from a first position in which the tool is retracted to a second position in which the tool inserts into the interior of the lumen behind the implant disposed within the lumen. 前記少なくとも１つのアクチュエータは、前記移植体を前記遠位開口部から展開させるために、前記ノーズコーンを前記ツールに対して引き出すように構成される、請求項１２に記載のシステム。 The system of claim 12, wherein the at least one actuator is configured to retract the nosecone relative to the tool to deploy the implant from the distal opening. 前記少なくとも１つのアクチュエータは、前記移植体を前記遠位開口部から展開させるために、前記ツールを前記ノーズコーンに対して前進させるように構成される、請求項１２に記載のシステム。 The system of claim 12, wherein the at least one actuator is configured to advance the tool relative to the nosecone to deploy the implant from the distal opening. 前記組織カートリッジの前記遠位シャフトは、粘着性物質を送達するように構成される、請求項１に記載のシステム。 The system of claim 1, wherein the distal shaft of the tissue cartridge is configured to deliver an adhesive substance. 前記遠位シャフトは、約２．８５mm以下の角膜切開を通じて挿入するように寸法構成される、請求項１に記載のシステム。 The system of claim 1, wherein the distal shaft is sized and configured for insertion through a corneal incision of about 2.85 mm or less.
