Abstract: The application provides a valve clamping system. The valve clamping system includes a pushing device and a valve clip with coatings. The valve clip includes a push rod, the coatings, and a proximal clamping plate, and a distal clamping plate. The proximal clamping plate and the distal clamping plate extend radially outwardly relative to the push rod. The distal clamping plate is connected to the push rod. The proximal clamping plate is arranged between the push rod and the distal clamping plate. A valve holding space is formed between the proximal clamping plate and the distal clamping plate. The push rod is capable of driving the distal clamping plate to be expanded radially. The proximal clamping plate is capable of expanding toward the distal clamping plate by an elastic strain of the proximal clamping plate and is configured to clamp a valve tissue received in the valve holding space.

Abstract: Disclosed are a sheath adjustable in multiple directions and a transcatheter interventional system. The sheath that can be adjusted in multiple directions includes: a body section, a bending section, connected with the distal end of the body section, the bending section is a multi-layer composite tube body and includes a plurality of segments, the middle layer of the multi-layer composite tube body is a woven mesh, and the density of the woven mesh of the plurality of segments is gradually reduced in the direction from the proximal end to the distal end; and at least a pair of traction mechanisms, each pair of the traction mechanism respectively passes through the bending section and the body section, to adjust the bending angle of the bending section to different directions.

Abstract: Disclosed are a valve clamping device and a valve clamping system, wherein the valve clamping device comprises: a supporting portion provided along an axial direction; a hollow adjusting portion, wherein at least part of the supporting portion is provided in the adjusting portion, one end of the adjusting portion is sleeved outside the supporting portion, and the other end of the adjusting portion is movable with respect to the supporting portion; a clamping portion surrounding an outside of the adjusting portion; and a driving portion connected to the clamping portion to drive the clamping portion to be close to or away from the adjusting portion.

Abstract: A valve clamping system capable of being independently controlled is provided. The valve clamping system includes a valve clip and a delivery device configured to deliver the valve clip. The valve clip includes a fixing base and proximal clamping pieces capable of being folded or unfolded relative to the fixing base. The delivery device includes a delivery sheath and control parts. The delivery sheath defines at least one pair of first cavities that are symmetrical about an axis of the delivery sheath and axially extend, and each control part movably threads the at least one pair of first cavities. Each control part is connected to one corresponding proximal clamping piece, so as to control the proximal clamping pieces to be folded or unfolded relative to the fixing base.
