Embodiment
For term defined below, difference is either only given elsewhere in specification in claim
Definition, otherwise should using these definition.
Regardless of whether explicitly pointing out, it is assumed that all numerical value are modified by term " about ".Term " about " is usual
Refer to those skilled in the art will be considered that be (that is, with identical function or result) suitable with described value number range.
In many cases, term " about " may include to be rounded to the numerical value closest to effective digital.
Refer to the attached drawing is answered to read following detailed description, wherein reference similar in different accompanying drawings represents similar member
Part.Accompanying drawing (it is not necessarily to scale) describes exemplary embodiment, without being intended to limit the scope of the present invention.
The disease and/or health for influenceing cardiovascular system are universal.Generally, carried out by being directly involved treatment
The treatment of cardiovascular system is the gimmick of comparative maturity.Medicine equipment is needed to use to carry out in above-mentioned interventional procedure, this hair
The bright improvement carried out aiming at this medicine equipment.
Device disclosed herein is namely based on the improvement of the medicine equipment operating side of angiocardiopathy progress, may also provide perhaps
The desired character and benefit added more, as described in detail below.
Above-mentioned treatment system is usually conduit system, with reference to Figure 11 and Figure 14, and it includes outer sheath 100 or and at least
The inner catheter 110 of outer sheath 100 is extended partially through, implantation silk guide passage 111 and manipulation line are provided with inner catheter 110
Passage 112 (is shown in broken lines one part) in fig. 12.In the delivery process of implant 200, medical device implants 200
It can be moved under the guiding of seal wire in silk guide passage, handle is arranged on the end of above-mentioned outer sheath, belong to an independent work(
Can part.
Implant is usually plugging device, with the medical element such as septate plugging device or screen pack, but is not limited to above-mentioned
Type.
Above-mentioned outer sheath, inner catheter composition conduit system, typically elongated part insert blood vessel from wound, directly
Logical lesion, during advance, when running into branch pipe, it may occur that turn to, the steering of current outer sheath is to pass through
Experiential operating, especially at vascular bifurcation, when needing to turn to branch vessel by main blood vessel, often occur operational error
Situation, solved for this problem.
The handle 300 is arranged on the outer end of outer sheath 100 and inner catheter 110, usually the operating side of doctor's hand.Pass through
The trend of operation at the end, control outer sheath and inner catheter, and internal seal wire accurate expanding-contracting action.
In use, the outer sheath 100 in system can percutaneously advance through vascular system to the position of neighbouring region-of-interest.
For example, through vascular system to the position adjacent to defective aorta petal or damage location.In delivery process, implant
200 can be with elongated and low profile " delivering " prominent form in outer sheath 100.Once positioning, implant 200 is internally led
By implant " release " in the presence of silk.Implant 200 can be actuated to expand into implant suitable for being implanted into vivo.It is logical
Often, implant is memory alloy material, after implant 200 is properly positioned in vivo, and the outer sheath in system can be from
Removed in vascular, and implant is left in place to play a part of such as repairing.The improvement of the present invention is outside
Operation handle part.It can both have been manipulated by outer handle section from vitro, and realize above-mentioned accurate operation.
Outer sheath 100 has proximal portion 101 and distal portion 102.Distal portion 102 can be interior with what is increased or extend out slightly
Footpath, it can provide additional space to remain at implant 200.For example, outer sheath 100 is along proximal portion 101 and above-mentioned
It is attached between handle, for example, is threadedly coupled or snaps connection.Can be distal tip in the distal end of distal portion 102, it can
To extend out or with the shape as funnel.Shape as funnel increases external diameter of the outer sheath at distal tip
(and internal diameter), and can help to that implant 200 is inserted and/or is reinserted into outer sheath.Outer sheath 100 can have big
The constant external diameter of body.For example, the external diameter of outer sheath 100 can be at about 0.3 to 1.3 centimetres, certainly, it is contemplated that other embodiment party
The different sizes of formula, its external diameter with outer sheath and/or internal diameter (are suitable to suffer from comprising the different bodily forms including children including those
The size of person) and/or layout.It is contemplated that outer sheath can also have the length for being suitable to reach expected region-of-interest in vivo.
To adapt to the path of blood vessel, outer sheath 100 is also flexible, and especially flexible close to distal portion, it is special that the position is designed to
The structure at other positions is different from, the formation of the bending can carry out control substantially by operation handle position, described herein
Substantially control refer to control trend substantially, and alter course, can be reduced to blood vessel by handle control in the progress of blood vessel
Wound, improves comfortableness.In one example, (measured since the center of outer sheath 100) sweep can about 5 to
6 centimetres, the size is merely illustrative, is not intended to the limitation present invention.
Outer sheath 100 can be made up of single integrated pipe or assembly of elements.Such as braid, coil, mesh, and its group
The common patterns such as conjunction.
Inner catheter 110 includes polymeric material, the polymeric material of polyether block amide of such as PEP, and
Seal wire 410 and manipulation line are worn in inner catheter, wherein seal wire sets middle position, and quantity is one, and seal wire can be logical with seal wire
Moved axially in road 111, manipulation line can be moved in manipulation line passage 112, but sufficiently small, the blood vessel that gap should be controlled
In blood can not be flowed back from gap.
Above-mentioned manipulation line collection is fixed in distal end portion, and fixed form is is permanently fixed, such as heat seal, riveting.Above-mentioned
It is four to manipulate line, and facing each other is one group, can be divided into left and right manipulation line 411 and forward and backward manipulation line 412 according to orientation,
Four above-mentioned manipulation lines are centered around around seal wire, are evenly arranged, effect is the change with left and right directions before and after controlling respectively
To, formed and effectively controlled, the steering of control outer sheath distal end and trend.
Above-mentioned manipulation line can be reinforced fiber, i.e. optical fiber and the complex of reinforcing fiber, with certain stretching
Intensity, while inside is compounded with optical fiber, the distal end portion of optical fiber exposes to outside, forms such as illumination, the function of local tomography, with
Beneficial to the progress of operation, inside can especially be detected.
In some cases, various sensors, or ultrasonic probe etc. can also be integrated with above-mentioned manipulation line.
Target spot, such as plutonium alloy point, in favor of the monitoring of imaging device are provided with the distal end portion of outer sheath 100.
The need in view of steering, set in the inner catheter 110 close to the cm of 200 side of distal end portion implant 10
Into cavity structure 113, cavity structure 113 be along axis direction set it is multiple, in favor of turn to, as shown in figure 13, cavity
For multiple, such as space of puffy, bending can be formed.After manipulation line is pullled, bend here at first, and then
Control and guide outer sheath and inner catheter steering.
Above-mentioned outer sheath and inner catheter are routine techniques in PCI, and its technical parameter and relevant criterion borrow existing
The explanation of big length is no longer carried out in technology, the present invention.
