Description
本開示のいくつかの態様によれば、医療装置は1つ以上のリザーバーを備える。リザーバーは、本明細書の組成物用の容器として機能し得る。好適なリザーバーは、例えば、シリンジ(例えば、手動又は自動注入システムに適合するシリンジバレル)、プラスチックバッグなどの可撓性のポーチ、及び好適な注入針とともに使用するように構成された別の流体容器を含み得る。リザーバーに好適な材料の例は、限定ではないが、環状オレフィンコポリマー、環状オレフィンポリマー、ポリプロピレン、ポリカーボネート、ポリ塩化ビニル、ガラスなどが含まれる。
いくつかの態様では、組成物は、全体の切除処置に亘って組織層の分離を維持し得る。ゲル組成物の一部は、切除工程により除去され得る。組織を切除した後、ゲル組成物の残った部分は、水又は生理食塩水を用いてその部位から洗い流されるか、又は、自然に組織の中に拡散し得る。
以下の実施例は、限定ではなく、本開示を例示することを意図したものである。本開示は、上記説明及び以下の実施例に一致する追加の態様及び実施形態を包含することが理解できる。
この実施例は、本開示の実施形態に係るゲル組成物を調製する為の例示の方法について説明する。1.125gのKelcogelCG-LAジェランガムと、0.01gのFD&C Blue1とを899gの水に加えて予備混合物を形成した。予備混合物は75℃になるまで攪拌しながら加熱した。次に、加熱した予備混合物に、8.1gの塩化ナトリウムと、0.132gの塩化カルシウム2水和物とを添加して混合して、混合物を形成した。次に、混合物を10ccのシリンジのバレルの中に導入した。充填したシリンジは、約122℃で約30分間オートクレーブすることにより滅菌した。
本明細書及び実施例は、例示としてのみ考慮されることを意図したものであり、本開示の真の範囲及び主旨は、以下の請求項の記載により示される。
