| 摘要 |
The present invention relates to a vascular closure device for sealing a puncture site in a vascular wall comprising a sheath (10) having a distal end and at least one proximal end, wherein the sheath (10) comprises a tubular body (100). The vascular closure device (1) is characterized in that at least one distal balloon member (11) is firmly arranged at the distal end of the tubular body (100) of the sheath (10) and at least one expandable anchor member (12) is firmly arranged proximal to the distal balloon member (11) on the tubular body of the sheath (10), wherein at least the distal side of the distal balloon member (11) is a pressure area for applying pressure on the outside of the vascular wall. Furthermore a method of positioning of a vascular closure device (1) is described. |
