Abstract
Description
第一及び第二のバットレスが前記ステープラーによって前記患者に作り出された前記孔を補強する。
本発明のバットレスと円形ステープラーとの適合性を評価するために、67%PGA:33%TMC (w/w)でウエブ密度が約0.5 g/ccの二つのバットレスが作られた。これらのバットレスは、円形ステープラー(ILS 29 mm, Ethicon Endosurgery, Somerville NJ)と共に使用するように外径約30 mmの円形に作られた。バットレスは、約0.25 mmという一様な厚さで、直径約6.3 mmの中央の孔が設けられた。各バットレスの中央領域には、また、直径約19.1 mmで厚さが約0.6 mmの円形シリコーン補強材が設けられた。各補強材には、その中央に直径が6.3 mmの孔が設けられた。各バットレスの一つの面に一つの補強材が、それぞれの部材の中央の孔を整列させて、MED-1356 シリコーン接着剤、Nusil Technologies, Carpenteria, CA,を用いて接着された。
6突出部を有するバットレスのある好ましい実施形態が、7%PGA:33%TMC (w/w)でウエブ密度が約0.5 g/ccの材料から次の方法によって作られた。二つのアクリル・シート、各ほぼ1.6 mm厚さ、がレーザー・テーブルにダクト・テープでしっかりとテープ固定された。レーザー・テーブルは、煙を逃がすためにパーフォレーションを有し、コンピューターによって運動制御される切断ヘッドを備えていた。アクリル・シートはレーザー(Laser Machining Inc., Model C-42, Somerset, WI)によって図9Aに示されているような第一のパタンにカットされた。一回目のレーザー切断はこのパタンを描くように行われ、次に二回目のレーザー切断が同じパタンで、両方のアクリル・シートを完全に通して確実に切断されるように行われた。レーザーで切断されたアクリル材料の片を取り出した。残りのアクリル・シートはレーザー切断テーブルに依然としてダクト・テープで取り付けられたままであった。
