Description
本出願は、2002年6月27日付けで出願された、米国仮出願第60/392,669号に基づき、35U.S.C.§119(e)による優先権を主張する。
フィブリングルーは、主として、局所的外科用接着剤又は止血剤として使用される血液誘導物として知られる。異種起源のフィブリングルーを得るため、トロンビン又はバトロキソビンのようなヒト又は動物由来のタンパク質活性剤と関連して、ドナーからの濃縮されたフィブリノーゲンを含有する幾つかのキットが市場にて入手可能である。
本出願は、2002年4月9日付けにて発行された、米国特許第6,368,298号の主題を引用することにより組み入れる。本出願は、また、2002年1月15日付けにて出願された、米国特許出願第10/053,247号、及び2002年6月27日付けにて出願された、米国特許出願第60/392,669号の主題を引用することにより組み入れる。
本発明による「直ちに使用可能な」キットは、凝固活性剤として塩化カルシウムを含有する密封した容器を含み得る。塩化カルシウムは、患者の血漿が密封した容器内に導入されたとき、患者の血漿中に存在するフィブリノーゲンを活性化する。
本発明によるキットに適した容器は、実施例1にて以下に説明するように、抗生物質用のガラス容器を包含する。ガラス又はプラスチック製の試験管もまた使用し得る。容器の好ましい容積は、5〜15mlである。試験管は、好ましくは直径12〜16mmの範囲及び高さ75〜100mmの範囲である。容器は、容器が排気されたとき、その内側空間と大気との間の圧力差に起因する圧力に耐え得るよう適切な厚さでなければならない。好ましくは、底が半球状又は円錐形の試験管は厚さ0.7mm、底が平坦な試験管は厚さ1mmである。プラスチック製容器は、生産後少なくとも12ヶ月真空圧を保つことを保証し得るよう、好ましくは0.2〜0.8mm厚の透明なポリエステル樹脂製である。製造
後、プラスチック製試験管は、使用日まで完全な気密性を保証するため、好ましくは熱密封した内側ポリエチレン層を有する錫箔真空気密容器内に入れる。
容器又は試験管は、容器が完全に気密であることを保証するため、並びに化学成分を導入した後及び蒸気又は放射線滅菌処理ステップの前に真空栓をすることを許容するために適した、ゴム又はシリコーンの穿刺可能なキャップにより密封し得る。
フィブリン安定剤であるトラネキサム酸を使用することができるが、純粋な結晶性ε−アミノカプロン酸もまた適する。20mlの血漿の量に適した25mlの容器を使用するとき、その量は、約1gである。フィブリン安定剤を使用する必要がない場合もある。フィブリン及び血小板のネットワークに包含させるために、性能を向上させるその他の治癒剤を第二の容器に追加し得る。その例として、非限定的に、骨及び軟組織移植片、足場材料、抗生物質、鎮痛剤、幹細胞、癌治癒用の化学毒性剤、免疫抑制剤、所望の分子を発現するよう設計した細胞、及びそれらの組み合わせを包含する。
