Abstract
The utility model provides a kind of left ventricular lead by the fixed prevention dislocation of balloon expandable, it is characterized in that, including lead body, the head of the lead body is equipped with the sacculus for preventing lead body abjection blood vessel for withstanding vascular wall, and the sacculus can be inflated or deflate.The utility model adds a sacculus in left room conducting wire head end commercial at present, wire end is connected to by the channel in conducting wire, for syringe after being found in art to suitable left room pace-making site by tail end to inflated, balloon expandable can assist fixed conducting wire.
Description
Technical field
The utility model relates to a kind of left ventricular leads, lead for being implanted into left room in cardiac resynchronization therapy (CRT) art
After line, conducting wire is more firmly fixed in coronary venous.
Background technique
Current left room conducting wire is expanded generally by electrode section or wing electrode is fixed in coronary venous, pre- anti-electric
Pole dislocation.As shown in Figure 1, to be traditional with the left room conductor structure schematic diagram for expanding electrode, the left ventricular lead packet
Include lead body, the head end of lead body is equipped with first electrode 1 and second electrode 2, first electrode 1 and second electrode 2 and blood vessel
Pace-making is realized in wall contact discharge, and 3 sets of oversleeve of anchoring is located at extravascular portion outboard in lead body, and the end of lead body is set
Have the part 4 for being connected with pacemaker, in use, 5 above section of line of demarcation be set to it is intravascular, 5 or less line of demarcation is partially set
In outside blood vessel.But the outer diameter for expanding electrode or wing electrode be it is fixed, intravascular be still easy to happen dislocation, research thicker
It shows that left room dislocation incidence is 4.3%, and dislocates and generally require re-operation, damage and the warp of more bodies are brought to patient
The burden of Ji.
Summary of the invention
The purpose of the utility model is to provide a kind of left ventricular leads, for preventing the postoperative short-term and long-term left room CRT
Conducting wire dislocation.
In order to achieve the above object, the utility model provides a kind of left ventricle by the fixed prevention dislocation of balloon expandable
Conducting wire, which is characterized in that including lead body, the head of the lead body is equipped with for withstanding vascular wall to prevent conducting wire sheet
Body deviates from the sacculus of blood vessel, and the sacculus can be inflated or deflate.
Preferably, it is equipped in the lead body for the pipeline to inflated or deflation, the end of lead body
Equipped with inflating port, the inflating port passes through the piping connection sacculus.
It is highly preferred that the inflating port is equipped with valve, the valve can be connect with syringe, the syringe
For to inflated.
Preferably, the head of the lead body is additionally provided with first electrode and second electrode.
It is highly preferred that the sacculus is located at the proximal end of first electrode.
Compared with prior art, the utility model has the beneficial effects that
The utility model adds a sacculus in the proximal end of left room conducting wire first electrode commercial at present, by conducting wire
Channel be connected to wire end, filled by the syringe of tail end to sacculus after being found in art to suitable left room pace-making site
Gas, balloon expandable can assist fixed conducting wire.
The utility model safe operation not will increase the risk performed the operation at present；Apparatus structure is simple, need to only apply at present
Conducting wire close electrode area add sacculus.
Detailed description of the invention

Fig. 2 is the left ventricular lead schematic diagram by the fixed prevention dislocation of balloon expandable in embodiment 2.
Specific embodiment
Clear, complete description is carried out to the embodiments of the present invention below in conjunction with embodiment, it is clear that described
Embodiment be merely to illustrate a part of the embodiment of the utility model, and be not construed as limitation the scope of the utility model.With
Upper only the utility model preferred embodiment, is not intended to limit the utility model, all essences in the utility model
Mind and principle within, any modification, equivalent replacement, improvement and so on, should be included in the protection scope of the utility model it
It is interior.
Embodiment 1
As shown in Fig. 2, the left ventricular lead by the fixed prevention dislocation of balloon expandable of the present embodiment includes lead body
11, the head of the lead body 11 is equipped with the sacculus 12 for preventing lead body abjection blood vessel for withstanding vascular wall, described
Sacculus 12 can be inflated or deflate.Sacculus 12 is located at the proximal end of the first electrode of lead body 11.
It is equipped in the lead body 11 for the pipeline inflated for deflated to sacculus 12, the end of lead body 11
Equipped with inflating port 13, the inflating port 13 passes through the piping connection sacculus 12.The inflating port is equipped with valve, described
Valve can be connect with syringe, the syringe is used for inflated.
The head of the lead body 11 is additionally provided with first electrode 1 and second electrode 2, first electrode 1 and second electrode 2
It realizes and paces with vascular wall contact discharge, 3 sets of oversleeve of anchoring is located at extravascular portion outboard in lead body, lead body
End is equipped with the part 4 for being connected with pacemaker.
In use, by left ventricular lead by subclavian vein, in right room to coronary venous, in coronary venous depths in art
Sacculus 12 is strutted to inflated through inflating port 13 by syringe after finding suitable left room pace-making site, it is therefore an objective to anti-
Only conducting wire is expanded in coronary venous distraction by sacculus 12, and the short-term support prevention by sacculus 12 in coronary venous is led
Line dislocation, for a long time by sacculus 12 and the fixed prevention conducting wire dislocation of endangium adhesion.
