Title:
自己拡張型ステントのための流体圧を用いた再捕捉手段を備えた折り返し膜
Document Type and Number:
Japanese Patent JP2008541786
Kind Code:
A
Abstract:
A medical device comprising a catheter having a retractable outer sheath and a rolling membrane. The catheter includes a catheter inner shaft about which a stent in a reduced diameter configuration may be disposed. A stent retaining region of the sheath is disposed about the stent to retain the stent in the reduced diameter state prior to delivery. The rolling membrane is engaged to a portion of the outer sheath at an engagement region. The rolling membrane is positioned between the catheter inner shaft and the outer sheath and prior to retraction of the sheath the rolling membrane is disposed about at least a proximal section of the stent and is rollingly retracted therefrom when the sheath is retracted to deliver the stent. The device also recaptures a stent by pressurizing a intra-catheter space, which results in the longitudinal movement of the outer sheath in a distal direction to recover and retain the stent.
