摘要： A stent delivery system and a method for delivering a stent are provided. The stent delivery system includes an outer sheath having a proximal portion, a distal portion and a first lumen extending at least partially through the sheath. The system further includes an inner shaft slidably received within the first lumen and extending at least partially through the sheath. A tubular non-expandable stent is slidably positionable within the first lumen, disposed distal to the inner shaft and operably contacts a pushing surface on the inner shaft. The inner shaft and the stent are slidable relative to the outer sheath, the outer sheath providing sufficient rigidity to the stent for delivery of the stent to a delivery site.

摘要： A balloon catheter including an inflatable balloon affixed to a catheter. The proximal end of the balloon is affixed to the distal end of the catheter so as to provide an air tight seal there between. A stiffening member extends distally of the distal end of the catheter and forms a slip joint connection with the distal end of the balloon to permit the distal end of the balloon to axially move or translate relative to the distal end of the catheter. The slip joint allows the axial length of balloon to change during inflation or deflation without transferring tensile or compressive forces between the balloon and the catheter, thereby preventing transverse creases from forming in the surface of the balloon and preventing the catheter from bowing. The stiffening member provides alignment and lateral support to the distal end of the balloon.
摘要翻译：气囊导管，其包括固定在导管上的可膨胀气囊。气囊的近端固定在导管的远端，以便在其间提供气密封。加强构件在导管的远端的远侧延伸并且与气囊的远端形成滑动关节连接，以允许气囊的远端相对于导管的远端轴向移动或平移。滑动接头允许气囊的轴向长度在充气或放气期间改变，而不会在气囊和导管之间传递拉伸或压缩力，从而防止在球囊表面形成横向折痕并防止导管弯曲。加强构件向球囊的远端提供对准和侧向支撑。

摘要： The present invention provides apparatus and methods for performing endoscopic mucosal resection and endoscopic submucosal dissection of tissue. In a first embodiment, a catheter having proximal and distal ends and a balloon disposed near the distal end of the catheter is provided. A portion of the distal end of the catheter is configured to be inserted beneath a section of mucosal tissue having a lesion, and the balloon is configured to be inflated to lift the mucosal tissue in an upward direction, thereby facilitating removal of the tissue comprising the lesion. Optionally, a surgeon may advance a needle knife through the catheter to further incise submucosal tissue while the balloon is in the inflated state. If desired, a flushing fluid may be provided to a target site during the procedure.
