Occluder and occlusion system
By incorporating a guidewire channel within the occluder, the problem of reconnection after detachment from the push cable is resolved, enabling the occluder to be retrievable and re-released, thus improving surgical efficiency and reducing risks.

AI Technical Summary
Technical Problem
Existing occluders are difficult to reconnect after being detached from the push cable, resulting in low efficiency and high risk of occlusion surgery, requiring surgical replacement of the occluder.
Method used
Design an occluder comprising an occluder mesh, a first end cap, and a second end cap, with an internal guide wire channel that allows the guide wire to remain in the guide wire channel after the occluder is detached from the push cable. The push cable can be reconnected to the end cap to retrieve the occluder.
Benefits of technology
It improves the efficiency of occlusion surgery, reduces surgical risks, and allows the occluder to be re-released and repositioned.

Abstract
The present invention relates to the field of interventional medical device technology, and specifically, to an occluder and an occlusion system. The occluder comprises an occlusion net, a first closure head, and a second closure head. The occlusion net comprises a net structure formed by weaving one or more braided wires and an inner cavity. One axial end of the occlusion net is gathered and fixed to the first closure head, and the other axial end of the occlusion net is gathered and fixed to the second closure head. A first through hole is formed in the first closure head, and a second through hole is formed in the second closure head. The first through hole, the inner cavity of the occlusion net, and the second through hole are in communication with each other to form a guide wire channel through which a guide wire can pass. By providing the guide wire channel, after the occluder is detached from a pushing cable, the guide wire can still be retained in the guide wire channel. When the release effect of the occluder is unsatisfactory, the pushing cable can be re-docked with and fixed to the second closure head along the guide wire, such that the occluder can be retrieved and re-released, the surgical efficiency is improved, and the surgical risk is reduced.
