Description
本出願は、2009年8月18日に出願した米国暫定特許出願第61/234,692号、2008年12月31日に出願した、米国暫定特許出願第61/142,053号、及び2008年12月31日に出願した、米国暫定特許出願第61/142,065号の優先権を主張する。これらの各出願は、ここに、全体を引用して組み込まれている。
臨床研究と診療は、組織部位近位に減圧を提供することが、その組織部位において新しい組織の成長を増進及び促進することを示している。この現象の適用は数多くあるが、減圧の適用は創傷治療に特に成功している。この治療(医学界では、頻繁に、「負圧創傷治療」、「減圧治療」、又は「真空治療」と呼ばれる)は、より早い治癒、及び肉芽組織の良好な形成を含む、多くの利点を提供する。典型的には、減圧は、多孔パッドあるいはその他のマニフォールドデバイスを介して組織に適用されてきた。多孔パッドは、減圧を組織に分配して、組織から取り出した流体を導くことができる孔を含んでいる。多孔パッドは、しばしば、治療を容易にするその他の部材を有するドレッシングに組み込まれている。足場も、欠陥部位に配置して、欠陥部位内への組織の成長をサポートすることができる。この足場は、通常、生体吸収性であり、新しい組織を適所に残す。
