    • Dilation catheters including a mechanism used in, for example, removing gas or air from the catheters are disclosed. A dilation catheter (1) may include an elongated tubular member (20) having a distal end and a proximal end, a proximal handle (10) proximate the proximal end of the tubular member, and an inflatable balloon (30) proximate the distal end of the tubular member with inflatable balloon being in fluid communication with a fluid port to supply inflation liquid to the inflatable balloon. The inflatable balloon may include an opening (39) for permitting gas to exit the inflatable balloon. In the proximate location of the opening, an expandable material or a barrier material that permits gas to exit through the opening, while retaining inflation liquid in the inflatable balloon.
    • 公开了包括用于例如从导管去除气体或空气的机构的扩张导管。 膨胀导管(1)可以包括具有远端和近端的细长管状构件(20),邻近管状构件的近端的近侧手柄(10)和靠近远端的可充气气囊(30) 具有可膨胀气囊的管状构件与流体端口流体连通,以向充气气囊供应充气液体。 可膨胀气囊可以包括用于允许气体离开可膨胀气囊的开口(39)。 在开口的邻近位置,可膨胀材料或阻挡材料,其允许气体通过开口排出,同时将膨胀液体保持在可充气球囊中。
