Delivery device for prosthetic mitral valve annuloplasty ring and prosthetic mitral valve annuloplasty ring delivery system
First Claim
1. A delivery device for a prosthetic mitral annuloplasty ring, the prosthetic mitral annuloplasty ring comprising an adjustment member which is configured to adjust a size of the prosthetic mitral annuloplasty ring and provided with an internal thread, the delivery device for the prosthetic mitral annuloplasty ring comprising a driving member and a connecting member disposed at a distal end of the driving member, wherein:
- the connecting member comprises an outer tube, an intermediate tube and an adjusting core, the driving member comprising an intermediate tube knob for adjusting a position of the intermediate tube and a core knob for adjusting a position of the adjusting core;
the outer tube has one end fixed to the distal end of the driving member and the other end configured to be fixed to the adjustment member;
the intermediate tube has a first end connected to the intermediate tube knob and a second end passing through a body of the outer tube along an axial direction of the outer tube, such that a portion of the intermediate tube is exposed, wherein the portion of the intermediate tube exposed from the outer tube is provided with an external thread complementary to the internal thread of the adjustment member, and the intermediate tube is movable within the body of the outer tube through manipulation of the intermediate tube knob; and
the adjusting core has a first end connected to the core knob and a second end passing through a body of the intermediate tube along an axial direction of the intermediate tube, the adjusting core being able to telescope within the body of the intermediate tube through manipulation of the core knob.

Abstract
A prosthetic mitral annuloplasty ring includes a wire, an adjustment member for changing a length of the wire and a jacketing annulus for adjusting a radial dimension of the mitral valve annuloplasty ring. The jacketing annulus is sleeved over the wire and forms, together with the adjustment member, a shape matching that of a native mitral valve annulus. After the prosthetic mitral annuloplasty ring is implanted by suturing in a conventional surgical procedure and the patient'"'"'s heart starts to beat again, the adjustment member can be connected to the delivery device and the wire length therein can be adjusted by a rotating operation of the delivery device so that the mitral valve annuloplasty ring will be expanded or contracted until the prosthetic mitral annuloplasty ring perfectly fits the native mitral valve annulus in shape, effectively avoiding the problem of incomplete mitral leaflet coaptation.
