Title:
新脈管形成のための心膜内薬物送達デバイス
Document Type and Number:
Japanese Patent JP4159357
Kind Code:
B2
Abstract:
A catheter for delivering agents to a defined biological space in vivo comprising: an inner catheter shaft defining at least one inner shaft lumen and having an inner shaft distal tip; an outer catheter shaft defining at least one outer shaft lumen and having an outer shaft distal tip; said inner catheter shaft longitudinally movable within and with respect to said outer catheter shaft; and at least one deployable support member disposed on at least one of said inner catheter shaft and said outer catheter shaft, wherein said at least one deployable support member comprises at least one inflatable balloon disposed on said inner shaft and in communication with said at least one inner shaft lumen. Preferably, the at least one deployable support member further comprises at least one deployable wire support in communication with at least one of said lumens of said inner shaft or said outer shaft. There is also disclosed a catheter for delivering agents to a defmed biological space in vivo comprising: an inner catheter shaft defining at least one inner shaft lumen and having an inner shaft distal tip; an outer catheter shaft defining at least one outer shaft lumen and having an outer shaft distal tip; said inner catheter shaft longitudinally movable within and with respect to said outer catheter shaft; and at least one deployable support member disposed on at least one of said inner catheter shaft and said outer catheter shaft, wherein said at least one deployable support member comprises at least one deployable wire support disposed on said inner shaft and in communication with said at least one inner shaft lumen, and at least one deployable wire support disposed on said outer shaft and in communication with said at least one outer shaft lumen.
