Be dispersed into 8 wires 42 that form it from extended the 2nd wire group 42G of cardinal extremity opening of the 2nd insulating properties pipe 27, these wires 42 utilize respectively welding and the pin terminal of the top end face 50A that is disposed at adapter 50 to be connected and fixed respectively.Here be connected region that fixing pin terminal (pin terminal 52) is configured as " the 2nd terminal group region " using forming the wire 42 of the 2nd wire group 42G.

The top ends (apart from top 10mm left and right) of the 3rd insulating properties pipe 28 is inserted into the 3rd lumen 13 of multi-lumen tube 10, and thus, the 3rd lumen 13 that the 3rd insulating properties pipe 28 and the 3rd wire group 43G extend links.

The endoporus of the 2nd protecting tube 62 that the 3rd insulating properties pipe 28 linking with the 3rd lumen 13 extends by the inside at handle 20 extends to the top end face 50A that adapter 50(pin terminal is configured) near, form the base end part of the 3rd wire group 43G guided to near the road of inserting adapter 50.Thus, from multi-lumen tube 10(the 3rd lumen 13) extended the 3rd wire group 43G can not be wound around, can (endoporus of the 3rd insulating properties pipe 28) extend in the inside of handle 20.

Be dispersed into 4 wires 43 that form it from extended the 3rd wire group 43G of cardinal extremity opening of the 3rd insulating properties pipe 28, these wires 43 utilize respectively welding and the pin terminal of the top end face 50A that is disposed at adapter 50 to be connected and fixed respectively.Here be connected region that fixing pin terminal (pin terminal 53) is configured as " the 3rd terminal group region " using forming the wire 43 of the 3rd wire group 43G.

Here as the constituent material of insulating properties pipe (the 1st insulating properties pipe 26, the 2 insulating properties pipes 27 and the 3rd insulating properties pipe 28), can exemplify polyimide resin, polyamide, polyamide-imide resin etc..Wherein, particularly preferably hardness is higher, easily inserts wire group, the polyimide resin that shaping can be thinner.

As the wall thickness of insulating properties pipe, be preferably 20～40 μ m, the preferred example illustrating is 30 μ m.

In addition, the constituent material of the protecting tube (the 1st protecting tube 61 and the 2nd protecting tube 62) being interpolated as insulating properties pipe, can illustrate the nylon based elastomers such as " Pebax " (registered trade mark of ARKEMA company).

According to the defibrillation probe 100 with above-mentioned such present embodiment forming, the 1st wire group 41G is in the interior extension of the 1st insulating properties pipe 26, the 2nd wire group 42G is in the interior extension of the 2nd insulating properties pipe 27, the 3rd wire group 43G is in the interior extension of the 3rd insulating properties pipe 28, thus in the inside of handle 20, the isolation of also the 1st wire group 41G, the 2nd wire group 42G and the 3rd wire 43G can being insulated completely.Its result, in the time having applied the required voltage of defibrillation, can prevent the short circuit (especially near the short circuit between the extended wire group opening of lumen) between the 1st wire group 41G, the 2nd wire group 42G and the 3rd wire 43G of inside of handle 20 reliably.

And; in the inside of handle 20; the 1st insulating properties pipe 26 is protected by the 1st protecting tube 61; the 2nd insulating properties pipe 27 and the 3rd insulating properties pipe 28 are protected by the 2nd protecting tube 52; thus, for example can prevent the situation that contacts because of carrying the component parts (movable member) of button 22, nuzzle up and cause insulating properties pipe to damage in the time of the deflection operation of the top ends of multi-lumen tube 10.

The top end face 50A that defibrillation probe 100 in present embodiment possesses the adapter 50 that multiple pin terminals are configured is divided into the 1st terminal group region, the 2nd terminal group region and the 3rd terminal group region, and by wire 41, wire 42 and wire 43 partition wall 55 of isolation mutually.

The partition wall 55 of dividing the 1st terminal group region, the 2nd terminal group region and the 3rd terminal group region is by being that the catheter-like in both sides with tabular surface is formed by insulative resin machine-shaping.As the insulative resin that forms partition wall 55, be not particularly limited, can use the common resins such as polyethylene.

The thickness of partition wall 55 is for example 0.1～0.5mm, illustrates that a preferred example is 0.2mm.

The height (distance from cardinal extremity edge to top edge) of partition wall 55 need to be higher than the standoff distance of the top end face 50A of adapter 50 and insulating properties pipe (the 1st insulating properties pipe 26 and the 2nd insulating properties pipe 27), in the time that this standoff distance is 7mm, the height of partition wall 55 is for example 8mm.Highly be less than on the partition wall of 7mm, cannot making its top edge be positioned at than the cardinal extremity of insulating properties pipe by tip side.

According to such formation, can reliably and fitly isolate the wire 41(that forms the 1st wire group 41G from the cardinal extremity part of the extended wire 41 of cardinal extremity opening of the 1st insulating properties pipe 26) and form the wire 42(of the 2nd wire group 42G from the cardinal extremity part of the extended wire 42 of cardinal extremity opening of the 2nd insulating properties pipe 27).

In the situation that not possessing partition wall 55, wire 41 and wire 42 fitly cannot be isolated to (division), likely cause their swinging cross.

And, thereby the wire 41 of formation the 1st wire group 41G of different voltage and the wire 42 that forms the 2nd wire group 42G are mutually isolated and can not be contacted by partition wall 55 to be mutually applied in polarity, therefore in the time using defibrillation probe 100, even if apply the required voltage of intracardiac defibrillation, at the wire 41(that forms the 1st wire group 41G from the cardinal extremity part of the extended wire 41 of cardinal extremity opening of the 1st insulating properties pipe 26) and the wire 42(of formation the 2nd wire group 42G from the cardinal extremity part of the extended wire 42 of cardinal extremity opening of the 2nd insulating properties pipe 27) between also can not be short-circuited.

In addition, in the time manufacturing defibrillation probe, the in the situation that of making a mistake in the time that wire and pin terminal are connected and fixed, for example, in the case of the wire 41 that forms the 1st wire group 41G has been connected with the pin terminal in the 2nd terminal group region, this wire 41, across next door 55, can easily be found the mistake connecting thus.

In addition, form the wire 43(pin terminal 53 of the 3rd wire group 43G) with wire 42(pin terminal 52) in the lump by partition wall 55 from wire 41(pin terminal 51) isolation, but be not limited to this, also can with wire 41(pin terminal 51) in the lump by partition wall 55 from wire 42(pin terminal 52) isolation.

In defibrillation probe 100, the top edge of partition wall 55 is positioned at than the cardinal extremity of the cardinal extremity of the 1st insulating properties pipe 26 and the 2nd insulating properties pipe 27 and all leans on tip side.

Thus, at the extended wire of cardinal extremity opening from the 1st insulating properties pipe 26 (forming the wire 41 of the 1st wire group 41G) with between the extended wire of cardinal extremity opening (forming the wire 42 of the 2nd wire group 42G) of the 2nd insulating properties pipe 27, partition wall 55 always exists, and can prevent reliably that wire 41 from contacting with wire 42 short circuit causing.

As shown in Figure 8, extend and 8 wires 41 being connected and fixed with the pin terminal 51 of adapter 50, extend and 8 wires 42 being connected and fixed with the pin terminal 52 of adapter 50, extend and the surrounding of 4 wires 43 being connected and fixed with the pin terminal 53 of adapter 50 is fixed by resin 58 from the cardinal extremity opening of the 3rd insulating properties pipe 28 from the cardinal extremity opening of the 2nd insulating properties pipe 27 from the cardinal extremity opening of the 1st insulating properties pipe 26, shape separately keeps fixing thus.

Keep the resin 58 of shape of wire to be formed as with adapter 50 cylindric with footpath, in the inside of this resin molded body, the state that the base end part in pin terminal, wire, insulating properties pipe and partition wall 55 are embedded into.

According to the flow chart shown in Figure 11, one example of the defibrillation therapy of the intracardiac defibrillation probe system to present embodiment describes below.

(1) first, connect supply unit 700 to defibrillation probe 100.Particularly, utilize connector-cable C1 that the adapter of defibrillation probe 100 50 and the probe adapter 72 of supply unit 700 are linked to (with reference to Step1, Fig. 9 of Figure 11 A).

(2) detect that the probe sequence storage part 111 of the arithmetic processing section 75 of this supply unit 700 that has connected the situation of supply unit 700 to defibrillation probe 100 from the memorizer of defibrillation probe 100 read sequence information, and it is initial connection or the connection again of identical or different supply units in order to judge that this is connected in this defibrillation probe 100, with reference to the first link information storage part 112 in memorizer 110, whether judgement has wherein been written into information, there is no writing information in first link information storage part 112 time, enter Step3, in the time having write information, enter Step4(with reference to Step2, Figure 12).

(3) while thering is no writing information in first link information storage part 112, the arithmetic processing section 75 of supply unit 700 is the first link information storage part 112 that has connected the moment (moment of internal clocking 753) of supply unit 700 and the sequence information (sequence information that memorizer 752 is stored) of supply unit 700 write in Step1 in the memorizer 110 of defibrillation probe 100, and enters Step5(with reference to Step3, Figure 12).

(4) while having write information in first link information storage part 112, the arithmetic processing section 75 of supply unit 700 is the event information storage part 113 that has connected the moment of supply unit 700 and the sequence information of supply unit 700 write in Step1 in the memorizer 110 of defibrillation probe 100, and enters Step5(with reference to Step4, Figure 12).

(5) in radioscopic image, confirm the position of the electrode (the formation electrode of 1DC electrode group 31G, 2DC electrode group 32G and base end side potential-measuring electrode group 33G) of defibrillation probe 100, and select to invest the electronic pads of surface from heart potential measuring unit 900(note) input to the part of the heart potential information (12 lead electrocardiogram) of ecg scanning instrument 800, and from the arithmetic processing section 75(Step5 of electrocardiogram input connector 77 input power devices 700).Now, a part for the heart potential information of input arithmetic processing section 75 is shown in heart potential information display section 78(with reference to Figure 13).

In addition, from the 1DC electrode group 31G of defibrillation probe 100 and/or the formation electrode of 2DC electrode group 32G via probe adapter 72, switching part 76, ecg scanning instrument adapter 73 input to the heart potential information of ecg scanning instrument 800, the heart potential information that inputs to ecg scanning instrument 800 via probe adapter 72, ecg scanning instrument adapter 73 from the formation electrode of the base end side potential-measuring electrode group 33G of defibrillation probe 100 is shown in ecg scanning instrument 800 monitor (omitting diagram omits).

(6) then, input is as the mode selector switch 741(Step6 of external switch 74).Supply unit 700 in present embodiment is " heart potential measurement pattern " in original state, and switching part 76 is selected the 1st contact, thereby guarantees to arrive via switching part 76 from probe adapter 72 path of ecg scanning instrument adapter 73.

(7) in the time that mode selector switch 741 is transfused to, the arithmetic processing section 75 of supply unit 700 judges that the moment of the first link information storage part 112 memorizer 110 from writing defibrillation probe 100 starts till whether the elapsed time in the moment of last writing events information storage part 113 has exceeded the use binding hours of the probe that the memorizer 752 of arithmetic processing section 75 stores, enter Step8 while not exceeding being judged as, being judged as while exceeding, cannot carry out later action and become " end " (Step7).

Here, being connected in this defibrillation probe 100 while being initial connection of the supply unit 700 in Step1 (via Step2,3,5,6 situation), owing to there is no writing information in event information storage part 113, therefore can enter Step8.On the other hand, being connected in this defibrillation probe 100 of supply unit 700 in Step1 is (via Step2,4,5,6 situation) while again connecting, and the moment of last writing events information storage part 113 becomes the moment that again connects supply unit 700 writing in Step4.

(8) when being judged as that moment from writing first link information storage part 112 starts till elapsed time in the moment of last writing events information storage part 113 while not exceeding the use binding hours of probe, arithmetic processing section 75 switches to " defibrillation mode " (Step8 of Figure 11 B) by the pattern of supply unit 700 from " heart potential measurement pattern ".

(9) as shown in figure 14, when thereby mode selector switch 741 is transfused to while switching to defibrillation mode, according to the control signal of arithmetic processing section 75, the contact of switching part 76 is switched to the 2nd contact, guaranteed to arrive via switching part 76 from probe adapter 72 path of arithmetic processing section 75, the path that arrives ecg scanning instrument adapter 73 via switching part 76 from probe adapter 72 is cut off (Step9).In the time that switching part 76 has been selected the 2nd contact, therefore heart potential information from the 1DC electrode group 31G of defibrillation probe 100 and the formation electrode of 2DC electrode group 32G cannot input to ecg scanning instrument 800(, also this heart potential information cannot be sent to arithmetic processing section 75.）。But, be not input to ecg scanning instrument 800 via the heart potential information of the formation electrode from base end side potential-measuring electrode group 33G of switching part 76.

(10) in the time that the contact of switching part 76 is switched to the 2nd contact, the resistance value (Step10) between 1DC electrode group (31G) and the 2DC electrode group (32G) of measurement defibrillation probe 100.The resistance value that is input to arithmetic processing section 75 via switching part 76 from probe adapter 72 can be shown in heart potential information display section 78(with reference to Figure 14 in the lump with a part for the heart potential information from heart potential measuring unit 900 of input arithmetic processing section 75).

(11) contact of switching part 76 is switched to the 1st contact, and (Step11) recovered in the path that arrives ecg scanning instrument adapter 73 via switching part 76 from probe adapter 72.

In addition, to be selected to the time (above-mentioned Step9～Step10) of the 2nd contact be for example between 1 second to the contact of switching part 76.

(12) arithmetic processing section 75 judges whether the resistance value of measuring in Step10 exceedes certain value, in the time not exceeding, enter next Step13(for applying the preparation of DC voltage), in the time exceeding, return to the location confirmation of the electrode of Step5(defibrillation probe 100) (Step12).

Here, in the time that resistance value has exceeded certain value, mean that 1DC electrode group and/or 2DC electrode group do not have fully and regulation position (tube wall of for example Coronary vein, the inwall of right ventricle) butt, therefore need to return to Step5 and again adjust the position of electrode.

Like this, can be only for example, just apply voltage when butt fully at the 1DC electrode group of defibrillation probe 100 and 2DC electrode group and regulation position (, the tube wall of Coronary vein, the inwall of right ventricle), therefore can carry out effective defibrillation therapy.

(13) input applies energy (Step13) while setting defibrillation as the electric energy configuration switch 742 of external switch 74.

According to the supply unit 700 in present embodiment, applying energy can set with 1J scale between from 1J to 30J.

(14) input built-in capacitance charging (Step14) to DC power supply unit 71 as the charge switch 743 of external switch 74.

(15) after charging finishes, input applies switch 744(Step15 as the electric energy of external switch 74).

(16) in the time that electric energy applies switch 744 and inputs, by arithmetic processing section 75, the contact of switching part 76 is switched to the 2nd contact, guarantee to arrive via switching part 76 from probe adapter 72 path of arithmetic processing section 75, cut off the path (Step16) that arrives ecg scanning instrument adapter 73 from probe adapter 72 via switching part 76.

(17) be switched to after the 2nd contact at the contact of switching part 76, apply polarity mutually different DC voltage (with reference to Step17, Figure 15 of Figure 11 C) via output circuit 751, switching part 76 and the probe adapter 72 of arithmetic processing section 75 to 1DC electrode group and the 2DC electrode group of defibrillation probe 100 from the DC power supply unit 71 of the control signal of arithmetic processing section 75 from acceptance.

Here, arithmetic processing section 75 is carried out calculation process and is transmitted control signal to DC power supply unit 71, make with the heart potential synchronous waveform of inputting via electrocardiogram input connector 77 apply voltage.

Particularly, in the heart potential waveform of successively inputting to arithmetic processing section 75 (from a part for 12 lead electrocardiogram of heart potential measuring unit 900), detect 1 R ripple (peak-peak), and obtain this peak height, then, moment (when next R ripple rises) at 80% the height (triggering level) that arrives this peak height from potential difference starts for example, to start to apply through after certain hour (, the utmost point short time of 1/10 left and right of the peak width of R ripple).

Figure 16 is the figure of the potential waveform for example, measured while representing to utilize defibrillation probe 100 in present embodiment to give regulation electric energy (setting output=10J).In the figure, transverse axis express time, the longitudinal axis represents current potential.

First, according to process certain hour (t after the potential difference arrival triggering level making in the heart potential waveform of input arithmetic processing section 75 ₀) after, the become-utmost point of 1DC electrode group 31G, the mode of the become+utmost point of 2DC electrode group 32G, between applies DC voltage, and thus, electric energy is supplied to measures current potential rising (V ₁it is crest voltage now.）。Passing through certain hour (t ₁) after, according to making the become+utmost point of 1DC electrode group 31G, the mode of the become-utmost point of 2DC electrode group 32G, between applies and reversed ± DC voltage, thus, electric energy is supplied to and measures the current potential (V that rises ₂it is crest voltage now.）。

Here, from arriving triggering level to the time (t that starts to apply ₀) be for example 0.01～0.05 second, illustrate that a preferred example is 0.01 second, time (t=t ₁+ t ₂) be for example 0.006～0.03 second, illustrate that a preferred example is 0.02 second.

Thus, can synchronously apply voltage with the heart potential waveform (being the R ripple of peak-peak) of input arithmetic processing section 75, can carry out effective defibrillation therapy.

Crest voltage (the V measuring ₁) be for example 300～600V.

(18) potential difference in heart potential waveform has been passed through certain hour (t after arriving triggering level ₀+ t) after, thereby accept to stop apply (Step18) from the voltage of DC power supply unit 71 from the control signal of arithmetic processing section 75.

(19) after applying of voltage stops, the record that applying (heart potential waveform when applying as shown in Figure 16) is shown in heart potential information display section 78(Step19).As displaying time, for example, be between 5 seconds.

(20) arithmetic processing section 75 of supply unit 700 is in the time utilizing defibrillation probe 100 to carry out defibrillation, setting value (input value of energy settings switch 742), the output voltage (V of Figure 16 of the electric energy that obtain resistance value (the intracardiac resistance value of first measuring while carrying out defibrillation) between 1DC electrode group 31G and 2DC electrode group 32G, will apply between 1DC electrode group 31G and 2DC electrode group 32G ₁the shown actual voltage applying) and the information of output time (the actual time applying shown in the t of Figure 16), these information with carry out the moment (moment of being determined by internal clocking 753) of this defibrillation and the sequence information (sequence information that memorizer 752 is stored) of supply unit 700 and be written in the lump event information storage part 113(in the memorizer 110 of defibrillation probe 100 with reference to Step20, Figure 17).

(21) contact of switching part 76 is switched to the 1st contact, recover in the path that arrives ecg scanning instrument adapter 73 via switching part 76 from probe adapter 72, is input to ecg scanning instrument 800(with reference to Step21, Figure 13 from the heart potential information of the 1DC electrode group 31G of defibrillation probe 100 and the formation electrode of 2DC electrode group 32G).

(22) to be shown in ecg scanning instrument 800 monitor, from the heart potential information (electrocardiogram) of the formation electrode (the formation electrode of 1DC electrode group 31G, 2DC electrode group 32G and base end side potential-measuring electrode group 33G) of defibrillation probe 100 and observe from the heart potential information (12 lead electrocardiogram) of heart potential measuring unit 900, if " normally ", finishes, when " undesired (ventricle trembles and do not cure) ", return to Step6(Step22).
