Abstract
The invention discloses a tapered metal bracket. The bracket which is tapered has the diameter at a center proximal end greater than that at the center far end; preferably, the diameter of the tapered metal bracket at the center proximal end is 0.5 mm greater than that at the center far end; and a polymer carrying an anti-proliferation drug is coated on the surface of the metal bracket. The tapered metal bracket can solve a stenosis lesion of a tapered vessel.
Description
Technical field
The present invention relates to medical instruments field, particularly a kind of cone-shaped metal support.
Background technology
Atherosclerosis is the aging modal pathological change form of human vas, is characterized in that ductus arteriosus wall thickens hardening, follows the string and tube chamber dwindles, and mainly involves big-and-middle-sized tremulous pulse and coronary artery.Along with atherosclerotic continuous progress, it is narrow in 75% o'clock to involve vessel lumen, the corresponding organ ischemia symptom can occur.Narrow in order effectively to remove, improve ischemia symptom, coming physical property to remove narrow by the implanted metal support at present is the most effective treatment means.
Fig. 1 is metal rack sketch map of the prior art.Present existing metal rack be with metal material make cylindrical, hollow, cradle wall is connect the support that forms by the metallic steel beam bridge.Stent diameter and blood vessel diameter after the expansion are suitable, select corresponding support according to the lesion vessels reference diameter.Get involved the doctor and by arteries (femoral artery or radial artery) metal rack that tightens is sent to diseased region, accurately behind the location, by balloon expandable metal rack is discharged.Under the effect of pressure, support is expressed to blood vessel wall with atherosclerotic plaque, thereby removes local luminal stenosis, improves blood flow.
Existing human vas support is the identical cylindrical metal support of two ends lumen diameter, but in the intervene operation treatment of reality, find, the blood vessel of human body is that tapered (blood vessel near-end to far-end is tapered a bit, there is gap in the two ends diameter), if select for use conventional bracket may make blood vessel near-end or far-end vascular dissection occur, at a loss what to do when this make to get involved doctor and selects support for the taper angiostenosis, can not choose the support of suitable this pathological changes.
Summary of the invention
Can not remove the deficiency of taper angiostenosis in order to overcome existing intravascular stent, the invention provides a kind of taper bracket for eluting medicament, this support can better be removed the narrow of taper blood vessel.
The present invention proposes a kind of cone-shaped metal support, this support is tapered, and its proximal part stent diameter is greater than the distal end stent diameter.
Preferably, the proximal part stent diameter of this cone-shaped metal support is than the big 0.5mm of distal end stent diameter.
Preferably, this cone-shaped metal rack surface bag has the polymer that carries anti-proliferative drugs.
Utilize the metal rack of taper of the present invention can better solve the stenotic lesion of taper blood vessel.
Description of drawings
Fig. 1 is the sketch map of metal rack in the prior art;
Fig. 2 is the structure chart of cone-shaped metal support of the present invention.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in more detail.
Because existing human vas support is the identical cylindrical metal support of two ends lumen diameter, therefore when the tapered situation of blood vessel that runs into human body, if select for use conventional bracket may make blood vessel near-end or far-end vascular dissection occur, at a loss what to do when this make to get involved doctor and selects support for the taper angiostenosis, can not choose the support of suitable this pathological changes.Therefore the present invention proposes a kind of taper bracket for eluting medicament, can better remove the narrow of taper blood vessel.Therefore, the invention provides a kind of cone-shaped metal support, specifically be the taper bracket for eluting medicament, this support is a kind of physical solution has the polymer that carries anti-proliferative drugs except the surface bag of human body coronary artery, renal artery, cerebrovascular stenosis metal (Nitinol or cochrome etc.) support.
Fig. 2 is the structure chart of cone-shaped metal support of the present invention.
With reference to Fig. 2, the configuration design of intravascular stent is tapered, wherein the proximal part stent diameter is greater than the distal end stent diameter, for example, nearly heart end support diameter is set to than the big 0.5mm of distal end diameter, also can be set to other values, to select different models according to the practical situation of patient's blood vessel.When target vessel is the taper blood vessel, use conical support can make the target lesion two ends adherent better, far-end can not cause vascular dissection, break because stent diameter is excessive simultaneously.Utilize taper bracket for eluting medicament of the present invention can better solve the stenotic lesion of taper blood vessel.
The metal rack of this taper of the present invention is identical with the material of existing metal rack, made by metal material, hollow, difference mainly is its shape difference, existing metal rack is cylindrical, and metal rack of the present invention is to be designed to taper, is that cradle wall is connect the support that forms by the metallic steel beam bridge.Stent diameter and blood vessel diameter after the expansion are suitable, select corresponding support according to the lesion vessels reference diameter.Get involved the doctor and by arteries (femoral artery or radial artery) metal rack that tightens is sent to diseased region, accurately behind the location, by balloon expandable metal rack is discharged.Under the effect of pressure, support is expressed to blood vessel wall with atherosclerotic plaque, thereby removes local luminal stenosis, improves blood flow.
Above-described specific embodiment; purpose of the present invention, technical scheme and beneficial effect are further described; be understood that; the above only is specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (3)
