Abstract
Description
本願は、米国特許法§119に基づき、米国仮特許出願第61/142,242号(2009年1月2日出願)に対する優先権を主張する。この仮特許出願の全内容は参照により、本明細書に援用される。
本発明は、再充填ポートおよび放出制御機構を有するその場で再充填可能な眼用移植物に関する。本発明はまた、上記眼用移植物を形成しかつ使用するための方法に関する。
緑内障、加齢性黄斑変性、2次性白内障などのような多くの眼の状態について、眼内の特定の位置に治療剤を提供し、長期間(例えば、数週間、数ヶ月もしくはさらには数年)にわたってそれら薬剤を提供することは、しばしば望ましい。眼用移植物は、治療剤をこの様式で提供するための少なくとも1つの機構を提供する。このように、製薬産業は、このような移植物の開発において、かなりの資源を捧げてきた。
本発明は、その場で再充填可能な眼用移植物に関する。上記移植物は、代表的には、本体部分、充填部分および放出制御機構を含む。上記本体部分は、治療剤を含む薬学的組成物の受容に適したレザバを規定する。上記充填部分は、上記薬学的組成物を、上記レザバ内に反復して位置づけることを可能にするために、上記レザバと流体連絡した状態にある充填ポートを規定する。上記放出制御機構は、長期間にわたって上記眼への上記薬学的組成物の制御された受動的放出を提供するに適した少なくとも1個の開口部を含む。上記眼への上記移植物の適用の際に、上記放出制御機構は、代表的には、上記眼内(例えば、上記眼の硝子体)に位置づけられ、上記充填部分は、上記充填ポートが、上記眼の硝子体の外側に、かつ上記鞏膜、核膜もしくは両方のおそらく外側にもアクセス可能なままであるように、上記眼の鞏膜もしくは核膜に隣接して位置づけられる。
本発明は、眼用移植物の適用および上記移植物を移植および/もしくは使用するための方法に基づく。上記移植物は、代表的には、薬学的組成物の受容に適したレザバを規定する本体部分を含む。上記移植物はまた、代表的には、上記移植物レザバが、上記薬学的組成物で最初に充填されることを可能にする充填部分を含み、代表的には、上記移植物が眼に移植された後に、上記移植物レザバが再充填されることを可能にする。上記移植物はまた、代表的には、上記眼への薬学的組成物放出の量を信頼が置けるように制御し得る放出制御機構を含む。
Claims (16)
- その場で再充填可能な眼用移植物であって、
レザバを規定する本体部分;
薬学的組成物がレザバ内に反復して位置づけられることを可能にするための該レザバと流体連絡した状態にある充填ポートを規定する充填部分であって、該薬学的組成物は、治療剤を含む、充填部分;
長期間にわたる眼への該薬学的組成物の制御された受動的放出を提供するに適した少なくとも1個の開口部を有する放出制御機構;
を含み、
ここで該眼への該移植物の適用の際に、該放出制御機構は、該眼内に位置づけられ、該充填部分は、該充填ポートが、該眼の硝子体の外側にアクセス可能なままであるように、該眼の鞏膜に隣り合う該硝子体の外側に位置づけられる、
移植物。 - 前記本体部分、前記充填部分もしくはこれらの組み合わせは、前記眼への前記移植物の適用の際に、前記鞏膜を覆って配置される接触表面を規定する、請求項1に記載の移植物。
