Description
Technical field
This utility model relates to a kind of Ink vessel transfusing implant and relates to be deployed in health tremulous pulse implant
Delivery apparatus.
Background technology
Aneurysm is one layer or the abnormal dilatation of multilamellar arterial wall, it is common that the knot caused by the hardening of arterial wall
Structure defect or, the other system defect such as such as dissection of aorta caused by hypertension causes.Universally recognized treatment
The method of the aneurysm (that is, " abdominal aortic aneurysm " or " AAA ") in ventral aorta is by surgical repair, relates to using artificial limb device
Official replaces aneurysm section.This operation is a big invention, but along with excessive risk and high mortality and sickness rate.
Typical AAA surgical repair enters aorta by abdominal incision with permission internist and performs.Once can enter
Enter aorta, aorta can be clamped to allow surgeon open aorta and sewing up the one of graft at heart
End.The other end of graft is being seamed to aorta through aneurysmal position.This allows blood to walk around aorta from heart
Weak area flowing.
One replacement scheme of surgical repair is to use endovascular treatment, is i.e. used for treating aneurysm, especially for AAA
Catheter directed technology.The exploitation of intravascular stent promotes endovascular treatment, intravascular stent can and already in connection with standard
Or thin-walled graft material uses, in order to form stent graft or interior graft.The potential advantages of minimally-invasive treatment include
Reduce operation M & M and shortening is in hospital and the intensive care unit time of staying.
In use AAA, one of graft (or interior prosthese) has a problem in that: false in great majority (if not all) AAA
Body is configured to AAA is rendered as kidney mo(u)ld bottom half AAA.The enough touch-down zones for graft are typically presented under kidney, thus real
Tight seal between inner surface and the outer surface of interior prosthese of the blood vessel wall of aorta now.Wherein, at renal artery and tremulous pulse
Distance (that is, " neck length ") between tumor is less than 15 mm, generally believes and uses the interior prosthese being designed for presenting under kidney to cause
Complication.Thus, in the presenting of the neck length less than 15 mm, for nearly kidney type AAA, other type AAA of kidney or kidney mo(u)ld top half AAA
Situation, in generally believing the existing AAA of use, prosthese will cause complication.
Others skilled in the art have attempted to be overcome now by the technology utilizing referred in the art as " windowing technology "
There is the defect of prosthese in AAA.This technology depend on home built customization window so that kidney and superior mesenteric artery be incorporated to for
Nearly kidney type AAA is in the interior prosthese this customized of kidney mo(u)ld top half AAA.In an aspect of windowing technology, internist is permissible
With hands, ready-made AAA implant is carried out opening or windows.The defect of the amended implant of windowing of internist is: plant
Enter body to permit without FDA, it is therefore desirable to internist applies for that supervision is exempted；And internist may spend make for several hours
This implant of windowing.In order to reduce these defects, manufacturer has been provided for based on the 6-12 week before predetermined implantation
The customization of aneurysmal imaging is windowed implant.But, a defect of this technology is: the anatomical structure of renal artery uniqueness can
Customization implant can be made to lose efficacy.For example, it may be possible to relate to extra renal artery or Hepatic artery, and upwardly-directed renal artery.
It addition, implant customized typically requires the long period time, within this long period time, the anatomical structure of AAA may significantly change
Become, thus cause bifurcated artery not to be directed at windowing.Although internist can implant the known implant of amendment on the same day (with
Problem time lag of the customization implant avoiding mentioning before), but the customization caused due to the angulation of anatomical structure is windowed
From the skew with the ideal alignment of bifurcated artery, therefore, this internist revises implant (and customization implant) possibility
The most undesirable.
Summary of the invention
Therefore, we have been designed that prosthese in a kind of implanted, and in this implanted, prosthese overcomes customization windowing
In shortcoming so that internist made customization implant by hand without several hours before transplant operation.Further, this practicality is new
Type overcomes and shifts to an earlier date, with before actual AAA operation, the anatomical structure being associated by the implant of Order creation in several weeks or move
The problem that arteries and veins tumor may change during customized implant and actual implantation.In short, this utility model provides three
Kind of key improvements: (1) is easy for simplifying and disposes one every time and window；(2) each opening is directed in situ with intended branch tremulous pulse,
Thus cause the clinical effectiveness of improvement；And (3) are because the various piece of interior prosthese is less, and it is only required to extra leading
Silk inner chamber, so the overall profile of this interior prosthese is ultralow (that is, less than the 16French of bigger autologous tremulous pulse, and at great majority
In the case of less than 12French).
