Description

いくつかの実施形態において、送達装置400は、送達装置400の筐体422上に構成されたノブ424をさらに含む。ノブ424は、内管404に機械的に接続されたスライダーまたはホイール式ノブでもよく、ノブ424を操作することによって、内管404は、外管402に対して移動し得る。たとえば、いくつかの実施形態において、内管404は、外管402に相対的に、及び網膜層202を通って網膜下腔に進み得る。いくつかのさらなる実施形態において、ノブ424は、複数の回転止め位置を提供してもよく、その結果ノブが一方の回転止め位置から他方まで移動するときに、内管404は、25ミクロンまでなどの、公知の距離まで外管に対して移動する。したがって、所望の距離Dは、ノブ424が回転止め位置の適切な数を移動することによって選択することができる。
