Abstract
Description
本明細書に説明されている実施形態は、血管内の(経皮的に送達される)下大静脈(IVC)フィルターデバイスおよび方法に関連し、具体的には、一時的IVCフィルターについてである。
一時的IVCフィルターは、永久フィルターに酷似して留置されるが、一時的IVCフィルターは、別個の血管内手術において、概して大腿静脈または内頸静脈付近から回収され得るように設計される。現在利用可能な一時的フィルターの多くは、フック状機構を含み、そのフック状機構によって、一時的フィルターは、S字スネアまたは複数ループスネアを用いることによって除去用のカテーテルまたはシース内に捕捉されて回収されることが可能である。
本明細書の実施形態は、この必要性と、他の医療デバイス用途に適用されるようなその他のものとを満たす。IVCフィルターに対して、当該システムは、(既存のまたは他の態様の)多種多様なフィルターアーキテクチャとともに使用され得る。したがって、新しいフィルターは、設計の制約および/または妥協がフィルター設計に対してほとんど要求されないことがある当該回収器との使用のために設計され得る。当該システムの機構は、米国特許第3,952,747号;米国特許第5601595号;米国特許第6,443,972号;米国特許第7,338,512号および米国特許第7,625,390号のうちのいずれかに説明されている既存のおよび/または改変されたバージョンのフィルターと、OPTEASE、GUNTHER TULIP、CELECTおよびOPTIONまたはその他を含む商業的に利用可能なデバイスとに関連して使用され得る(これらの特許出願のうちの全てが、任意の目的で、参照により、それらの全体が本明細書に援用される)。
