Description
このガラスの小びん178は空洞176内に配置されている。この空洞176は1つの環状の泡挿入物182により1列に並べられ、このガラスの小びん178の緩衝材が追加されている。このピッグ・ベース174は、対応する1つのピッグ・リッド184により閉鎖されている。好適には、このピッグ・ベース174には1つのラベル186が具備され、このラベルは収縮包装188の1つの外層によりこのベースに保持されている。
シード200には、外側の1つの表面に取り付けられた少なくとも1つのバーブ220が含まれている。シード200には、図示したように、2個以上のバーブ220が含まれるかもしれない。複数のバーブ220は、図示したように、シード200の周りを包む1つのカラー212に接続されるか、またはシード200に直接接着される。スリーブ32の内壁がシード200に対して複数のバーブ220を圧縮するように、シード200は矢印Aの方向にスリーブ32内に挿入される。埋め込み中、シード200がスリーブ32の遠位端部38に存在する場合、複数のバーブ220は外側に伸びて、前立腺被包204を係止し、シード200を周囲の組織に固定する。上に記載した複数のアンカー214、216、218と同様に、医師がスリーブ32を引き抜く時に、複数のバーブ220は1つまたは複数のフィラメント202に張力を作る。この張力は、複数のシード200に望ましい間隔を維持させる。
アダプター232の1つの近位端面236は、管腔234が器具スロット228とほぼ同軸であるように、器具226の1つのエッジと隣接している。アダプター232の1つの遠位端面238は、アダプターの1つの遠位端面がスリーブ32の管状部分の1つの近位端部とほぼ隣接するように、次いで、ハブ40内に挿入される。オブチュレーター42を用いて、次いで、組み立て工はシードおよびフィラメントからなる組み立て体をアダプター232を通し、ハブ40を通して、スリーブ32内に押し込む。
