Abstract
Description
本願は、米国仮特許出願第61/446,879号(2011年2月25日出願、名称「Reinforced Balloon Catheter」)の優先権を主張し、この出願は、参照することによりその全体が本明細書に援用される。
本発明は、バルーンカテーテルに関し、より具体的には、複数の補強され、同軸に方向付けられた内腔を有するバルーンカテーテルに関する。
バルーンカテーテルは、患者において、神経学的手技を実施するために、ますます多く採用されてきている。しかしながら、神経学的手技において使用するために意図されるバルーンカテーテルの設計パラメータは、心臓病学的手技等の非神経学的手技において使用されるバルーンカテーテルの設計パラメータと有意に異なる。例えば、神経構造内の循環系の幅は、身体の他の部分における循環系より有意に小さく、より蛇行性である。神経構造のより小さく、より蛇行性の領域にアクセスするために、バルーンカテーテルの外径を最小にする一方、カテーテルのプッシャビィリティおよび追従性を同時に維持する必要がある。
