Description
Technical field
The present invention relates to medical field, particularly relate to a kind of therapeutic medical heart volume reduction system.
Background technology
Heart failure has become the healthy heavy burden in the whole world, and whole world heart failure patient there are about 26,000,000 at present, and prevalence is
1-2%.More than 70 years old crowd's heart failure prevalence >=10% of American-European countries.In the heart failure patient course of disease of 74% at least one
Complication, this type of patient is easier to occur the deterioration of disease, causes admission rate and mortality rate to remain high again.Advanced heart failure prognosis
More worse than part entity tumor and myocardial infarction, 5 annual survival rates of severe patient are less than 20%.Heart failure brings for society simultaneously
Huge financial burden.
In recent years, being paid attention to by clinic more and more, it main reason is that it becomes whole world morbidity and dead head
Want one of inducement, even and if calcification score technology development widely available instantly, still have 20%～50% myocardial infarction patient
Can transfer heart failure patient to, and left ventricle geometry is as one of the main prognosis of heart failure, particularly myocardial ischemia
Heart geometry can be changed.Three coronary artery are easiest to myocardial infarction occur with anterior descending branch especially, the antetheca that result causes
, there is apex impaired movement even ventricular aneurysm in large area infarction, increases the weight of remodeling ventricle further and CHF occurs
Symptom.After acute anterior wall myocardial infarction patients, myocardial necrosis and scarring subsequently, cause left ventricular remodeling, causes left ventricle dilation and a left side
Ventricular systolic function declines.The important symbol of remodeling ventricle is exactly wall tension change and heart volume change.Therefore machinery
The minimizing bulk of left ventricle of property can alleviate wall tension thus improve remodeling ventricle, here it is the theory of surgery partial left ventriculectomy depends on
According to.Though the history in partial left ventriculectomy existing more than 50 years, surgery operating wound is relatively big, and to the requirement of surgery patient relatively
Height makes clinical practice limited.

Heart volume reduction system of the present invention provides the benefit that, barb plays fixation at cardiac muscle, prevents the dress after release
Put and be moved, stability and the intensity of heart volume reduction system can be effectively improved；Guidance system uses macromolecular material or gold
Belong to material, there is preferable propelling movement ability.Heart volume reduction system can be by puncturing mode, specifically by volume reduction being filled
Put and be housed in guidance system, penetrate on left ventricle surface and heart volume reduction system is delivered in human heart, be implanted in heart
In, capacity-reduction device operates by guidance system, sliding opening capacity-reduction device, by use multi-rod skeleton and isolating membrane
Compartmentation, effectively reduces ventricular volume, reduces ventricle tension force, improves the cardiac function of remodeling ventricle and patient.Overcome existing
The elastic performance of wadding is poor, cardiac stimulus inner chamber；And the shortcoming that existing wadding structure stimulates the apex of the heart etc..Heart volume reduction system
System fix and fit in heart by surface barb in heart inner cavity position, particularly cardiac lumen owing to disease is in irregularly
Shape, is prevented effectively from cardiac stimulus inner chamber, and the fixing pedestal that supports uses Thermoplastic polyurethane elastomer material simultaneously, can protect the heart
Point is not damaged, and utilizes the separation of isolating membrane, stops blood to flow into the apex of the heart, plays plugging action.Many by capacity-reduction device
Rod-type skeleton from swollen at cardiac lumen, effectively reduce ventricular volume, and reduces ventricle tension force, to reach to improve remodeling ventricle and trouble
The therapeutic purposes of the cardiac function of person；The metallic rod of guidance system and protection set unitary design, conveniently operate and exit heart.
Preferably, described multi-rod skeleton is by can making from swollen Nitinol.Niti material has Memorability and superlastic
Property characteristic, be effectively improved the size restoration of bracing frame and overall compliance, more effectively avoid cardiac stimulus inner chamber.
Preferably, a diameter of the 60～120mm of capacity-reduction device；Can effectively cover most patient demand.
Preferably, the quantity of described brace rod is 12-25, and fixed angle between brace rod described in each two be 15 °-
30°。
Preferably, described macromolecule isolating membrane is electricity textile polymer.This material has good biocompatibility, controls
Biological interaction and specialty filtering medium, and without or less fluid seepage performance, play the effect effectively blocked and isolate.
Preferably, described support pedestal and the type of attachment of capacity-reduction device be hot jet welding or UV optical cement bonding.Improve the heart
The stability that dirty volume reduction system is overall.
Preferably, described brace rod top turns up 40 °-50 ° along surrounding.
Preferably, a length of 1.5-3mm of described barb.
Preferably, described multi-rod skeleton and macromolecule isolating membrane use suture way combination fixing.This mode can make
Isolating membrane is effectively fixed on multi-rod skeleton and improves the support force of multi-rod skeleton.
Preferably, described support pedestal is formed in one with multi-rod skeleton.Seamless compartmentation can be played, improve heart
The structural stability that volume reduction system is overall, without dropping risk.
