Document Type and Number:
WIPO Patent Application WO/2021/082822
Kind Code:
A1
Abstract:
An adjustable valve clipping system comprises a delivery device (300) and a valve clip. The valve clip comprises a main body (100) and a clip adjustment mechanism (200). The main body (100) comprises a retaining base (10), a near end clip member (30), and a far end clip member (20). The retaining base (10) is used to connect the delivery device (300) so as to enable delivery of the main body (100) by the delivery device (300), and the near end clip member (30) and the far end clip member (20) engage so as to clip a valve tissue. The clip adjustment mechanism (200) is located between the delivery device (300) and the retaining base (10), and comprises an adjustment member (40) capable of sliding along an axial direction and sleeving onto the retaining base (10). When the main body (100) is closed, the adjustment member (40) presses against the near end clip member (30), so as to adjust a pulling strength of the main body (100) on the valve tissue. The invention ensures sufficient a holding force of the main body (100) to prevent loosening, and adjusts the pulling strength of the main body (100) on the valve tissue by means of the clip adjustment mechanism (200).
