Delivery device and delivery system

A delivery device, configured to deliver an implantable instrument, wherein the delivery device comprises:

• an operating handle, comprising an accommodating cavity;
• a regulating member, wherein in a natural state, the regulating member comprises a bent section, and an end of the regulating member that is away from the bent section extends into the accommodating cavity;
• and
• a first driving assembly, arranged on the operating handle, connected to the regulating member, and configured to control an axial displacement of the regulating member, so that the bent section of the regulating member abuts against an implantable instrument to achieve shaping of the implantable instrument, wherein the first driving assembly comprises a guide rail, a first rotating member and a second rotating member;
• the guide rail and the first rotating member are accommodated in the accommodating cavity;
• the guide rail is connected with the first rotating member and the second rotating member;
• wherein the second rotating member comprises a base, a regulating rod and a screw cap;
• the regulating rod is inserted into the base;
• the screw cap surrounds the regulating rod and the base;
• the base is rotatably connected with the operating handle;
• and the guide rail is connected with the regulating rod.

A delivery system, comprising:

• an implantable instrument comprising an occlusion frame that has a waist portion, the implantable instrument having a fixing member that surrounds the waist portions of the occlusion frame, and a channel extending axially from a distal end of the fixing member to a proximal end of the fixing member is formed;
• and
• a delivery device comprising:
• an operating handle, comprising an accommodating cavity;
• a regulating member, wherein in a natural state, the regulating member comprises a bent section, and an end of the regulating member that is away from the bent section extends into the accommodating cavity;
• and
• a first driving assembly, arranged on the operating handle, connected to the regulating member, and configured to control an axial displacement of the regulating member, so that the bent section of the regulating member abuts against an implantable instrument to achieve shaping of the implantable instrument;
• wherein the bent section of the regulating member of the delivery device is able to abut against the implantable instrument.
