Description
Technical field
The utility model belongs to insertion type the field of medical instrument technology, and it is medical to be related to a kind of unobstructed heart valve implanted
Sacculus.
Background technique
In recent years, it with the progress of interventional therapeutic technique, has been obtained quickly through catheter heart valves displacement or prosthetic
Develop and be applied to clinic, achieves more satisfied effect.It is performed the operation by minimally invasive intervention by insertion type artificial cardiac valve branch
Frame is implanted in the bicuspid valve or aorta petal of heart by balloon expandable, carries out phase to replace or repair the natural valve of damage
Close work.Insertion type artificial cardiac valve mainly includes bracket, and is set to the leaflet of internal stent, is pressed and is held in sacculus
On, by the full expansion of sacculus, heart valve is made to strut the original native valve of displacement.In terms of interventional therapy, sacculus is risen
To very crucial effect, so that interventional therapeutic technique process is not necessarily to open chest, thus wound is small, post-operative recovery is fast.For those mesh
Preceding conventional therapy means cannot extend its life or alleviate the valve stenosis patient of its pain, and sacculus interventional therapeutic technique provides
A kind of new solution.
CN 102921095A discloses a kind of novel passability valve or Angiectasis sacculus, by sacculus be fabricated to by
Center guide wire is inflated to periphery air bag, and the lumen for having multiple stringers straight-through between seal wire and periphery air bag passes through for blood flow,
In inflatable dilatation narrow zone, still there is blood flow to pass through in lumen, supplies distal end internal organs, however it is made of single sacculus, easily
In cause sacculus to slide the problem of.
CN 103622769A discloses a kind of three leaf-head capsules for spreading belt valve aorta petal bracket, including autumn nanmu
Sacculus, conduit and connector, the sacculus, which is connected by three single saccules by side, to be formed, and is passed through among three single saccules
Seal wire, the conduit stretch out sacculus and are broken down into two-chamber connector, the gas tube and gas transmission orifice of the conduit, the gas transmission
Orifice air-source or water source, the air-source or water source are connected to sacculus by gas tube；However since the sacculus is by three
Single saccule composition, unbalance stress is likely to result in balloon expandable, is still likely to result in sacculus displacement, or even make to heart
At added burden.
In conclusion currently used for the sacculus in interventional therapeutic technique, when application, also faces more problem.Such as sacculus
Easily sliding；Sacculus fills expanse process and cardiac flow is be easy to cause to block, and needs to use temporary pacemaker etc. for patient.Needle
To problem existing for sacculus used in existing insertion type, those skilled in the art always search for the method solved.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of this utility model is to provide a kind of unobstructed heart valve implanteds to cure
