Description
.Ps O\ (N \O ( n ( x Ett annat ändamål med uppfinningen är att åstadkomma en ballongkateter, som termiskt påverkar blodkärlets vägg men som inte koagulerar blodet i blodkärlet. Ännu ett ändamål med uppfinningen är att åstadkomma en bal- longkateter som vid termisk påverkan av blodkärlets vägg lämnar en slät yta på kärlväggen. Another object of the invention is to provide a balloon catheter which thermally affects the wall of the blood vessel but which does not coagulate the blood in the blood vessel. Yet another object of the invention is to provide a balloon catheter which in thermal impact of the blood vessel wall leaves a smooth surface on the vessel wall.
De för uppfinningen utmärkande särdragen framgår ur de bifogade patentkraven.The features characteristic of the invention appear from the appended claims.
Enligt en föredragen utföringsform av uppfinningen utgörs ballongenhetens värmeisolerande organ av en reflekterande beläggning anordnad på ballongenhetens ändytor, företrädesvis på ändytornas insidor.According to a preferred embodiment of the invention, the heat-insulating member of the balloon unit consists of a reflective coating arranged on the end surfaces of the balloon unit, preferably on the insides of the end surfaces.
Enligt en annan. utföringsform av' uppfinningen anordnas en som värmeisolering tjänande luftfylld kammare vid såväl den proximala som den distala änden av ballongenheten.According to another. embodiment of the invention, an air-filled chamber serving as thermal insulation is provided at both the proximal and distal ends of the balloon unit.
En tillkommande fördel med uppfinningen.erhålls om ett röntgen- kontrastmedel tillsätts den. heta vätskan. Kirurgen kan, då noggrant fastställa ballongkateterns position i kärlet.An additional advantage of the invention is obtained if an X-ray contrast agent is added to it. the hot liquid. The surgeon can then accurately determine the position of the balloon catheter in the vessel.
Uppfinningen kommer att beskrivas närmare nedan i anslutning till de bifogade ritningarna, i vilka fig. 1 är en längdsektionsvy av en ballongkateter enligt en första utföringsform av uppfinningen, fig. 2 är en tvärsektionsvy utmed linjen II-II i fig. 1, fig. 3 är en längdsektionsvy av en andra utföringsform av en ballongkateter enligt föreliggande uppfinning, fig. 4 är en tvärsektionsvy utmed linjen IV-IV i fig. 3 fig. 5 är en längdsektionsvy av en tredje utföringsform av -b J 'i \§§..I) cpfla i 3 en ballongkateter i enlighet med föreliggande uppfinning, fig. 6 visar en tvärsektion av ballongkatetern enligt fig. 4 i tryckavlastat tillstånd och fig. 7 visar en tvärsektionsvy av ballongkatetern enligt fig. 1 i trycksatt tillstånd.The invention will be described in more detail below in connection with the accompanying drawings, in which Fig. 1 is a longitudinal sectional view of a balloon catheter according to a first embodiment of the invention, Fig. 2 is a cross-sectional view along the line II-II in Fig. 1, Fig. 3 is a longitudinal sectional view of a second embodiment of a balloon catheter according to the present invention, Fig. 4 is a cross-sectional view taken along the line IV-IV in Fig. 3. Fig. 5 is a longitudinal sectional view of a third embodiment of -b J 'in §§. Fig. 6 shows a balloon catheter according to the present invention, Fig. 6 shows a cross section of the balloon catheter according to Fig. 4 in pressure-relieved condition and Fig. 7 shows a cross-sectional view of the balloon catheter according to Fig. 1 in pressurized condition.
Fig. l visar en ballongkateter innefattande ett kateterrör 1 och en långsträckt ballongenhet 2 anordnad vid kateterns distala ände. Axiellt i kateterröret löper en lumen 3 som via en öppning 4 i. kateterrörets väggyta står :i kommunicerande förbindelse med det invändiga utrymmet 5 av ballongenheten.Fig. 1 shows a balloon catheter comprising a catheter tube 1 and an elongate balloon unit 2 arranged at the distal end of the catheter. Axially in the catheter tube runs a lumen 3 which via an opening 4 in the wall surface of the catheter tube stands: in communicating connection with the internal space 5 of the balloon unit.
Fig. l och 7 visar ballongenheten i dilaterat, dvs. trycksatt läge, nedan kallat arbetsläget, medan fig. 6 visar ballongen- heten i tryckavlastat, evakuerat läge, dvs. det tillstånd ballongenheten intar vid dess införande i det blodkärl 6 vars ockluderade parti 7 skall öppnas. En guide-wire 8 har genom manipulering navigerats fram till det ockluderade partiet 7 och därefter har ballongkatetern trätts över guide-wiren och manuellt matats fram till det ockluderade partiet genom patien- tens blodkärlssystem. Kateterrörets 1 distala parti har ett koniskt spetsparti 9.Figs. 1 and 7 show the balloon unit in dilated, i.e. pressurized position, hereinafter referred to as the working position, while Fig. 6 shows the balloon unit in pressure-relieved, evacuated position, ie. the condition of the balloon unit upon its insertion into the blood vessel 6 whose occluded portion 7 is to be opened. A guide wire 8 has been manipulated to the occluded portion by manipulation and then the balloon catheter has been passed over the guide wire and manually fed to the occluded portion through the patient's blood vessel system. The distal portion of the catheter tube 1 has a conical tip portion 9.
Ballongenheten 2 har i det dilaterade tillståndet en axiellt långsträckt cylindrisk sektion 10, en distal ändsektion ll och en proximal ändsektion 12.In the dilated state, the balloon unit 2 has an axially elongate cylindrical section 10, a distal end section 11 and a proximal end section 12.
Enligt uppfinningen fylls det evakuerade invändiga utrymmet 5 med het, eventuellt trycksatt, vätska genom lumen 3. Enligt uppfinningen har den cylindriska sektionen 10 i ballongkate- terns arbetsläge en slät utvändig yta samt är framställd av värmeledande material så att en intim värmeöverförande kontakt erhålls mellan den cylindriska sektionen 10 och den invändiga ytan av blodkärlet 6. Värmeinnehållet i den heta vätskan koagulerar termiskt blodkärlets väggyta så att såsom resultat av värmebehandlingen blodkärlets väggyta blir slät, vilket v3- 'n C22*- 4 befrämjar cirkulationen. För att den heta vätskan inte skall koagulera blodet i blodkärlet finns värmeisolerande organ i form av en reflekterande beläggning 13 och en reflekterande beläggning 14 anordnade vid ballongenhetens distala resp. proximala ändsektion 11 resp. 12. Den reflekterande beläggnin- gen, som är anordnad på den invändiga ytan av ballongenheten, tjänar som värmeisolering genom att utnyttja den s.k. termosef- fekten. Termoseffekten kan förstärkas genom att även förse den utvändiga ytan av ändsektionerna 11 och 12 med en reflek- terande beläggning såsom antyds vid de streckade linjerna 15, 16.According to the invention, the evacuated interior space 5 is filled with hot, possibly pressurized, liquid through the lumen 3. According to the invention, the cylindrical section 10 in the working position of the balloon catheter has a smooth outer surface and is made of heat conducting material so that an intimate heat transfer contact is obtained between the the cylindrical section 10 and the inner surface of the blood vessel 6. The heat content of the hot liquid thermally coagulates the wall surface of the blood vessel so that as a result of the heat treatment the wall surface of the blood vessel becomes smooth, which v3 'n C22 * - 4 promotes circulation. In order for the hot liquid not to coagulate the blood in the blood vessel, heat-insulating means in the form of a reflective coating 13 and a reflective coating 14 are arranged at the distal resp. proximal end section 11 resp. 12. The reflective coating, which is arranged on the inner surface of the balloon unit, serves as thermal insulation by utilizing the so-called the thermos effect. The thermos effect can be enhanced by also providing the outer surface of the end sections 11 and 12 with a reflective coating as indicated by the dashed lines 15, 16.
Den reflekterande beläggningen kan t.ex. vara av silver, aluminium, eller guld som anbringats t.ex. genom målning, påàngning, limning eller svetsning.The reflective coating can e.g. be of silver, aluminum, or gold applied e.g. by painting, steaming, gluing or welding.
I fig. 3 visas en annan utföringsform av ballongkatetern enligt uppfinningen. Utförandet skiljer sig från det i fig. 1 genom att de värmeisolerande organen utgörs av en distal luftfylld kammare 17 och en proximal luftfylld kammare 18.Fig. 3 shows another embodiment of the balloon catheter according to the invention. The embodiment differs from that in Fig. 1 in that the heat insulating means consist of a distal air-filled chamber 17 and a proximal air-filled chamber 18.
Den distala kammaren 17 är bildad av en med kateterröret l koncentrisk och mot kateterrörets längdaxel lutande vägg 19 med en ringformad distal kantyta 20 tätande förankrad vid ett distalt parti 21 av kateterröret. Detta distala parti 21 är beläget ett stycke framför, dvs. distalt relativt ett första avsnitt 22 som är beläget framför' ballongenhetens distala ändsektion 11. En ringformad proximal ändyta 23 av väggen 19 är tätande förankrad vid ett radiellt sett yttre parti 24 av den distala ändsektionen ll av ballongenheten. På samma sätt är den proximala kammaren 18 bildad av en med kateterröret koncentrisk och mot kateterrörets längdaxel lutande vägg 25 med en ringformad proximal kantyta 26 tätande förankrad runtom ett parti 27 av kateterröret. Detta proximala parti 27 är beläget vid den proximala änden av ett avsnitt 28 som är beläget bakom, dvs. proximalt relativt ballongenhetens ändsek- tion 12. En ringformad distal ändyta 29 av väggen 25 är tätande förankrad vid ett radiellt sett yttre parti 30 av den proximala ändsektionen 12 av ballongenheten. En lumen 31 står .F s.The distal chamber 17 is formed by a wall 19 concentric with the catheter tube 1 and inclined to the longitudinal axis of the catheter tube with an annular distal edge surface 20 sealingly anchored to a distal portion 21 of the catheter tube. This distal portion 21 is located some distance in front, i.e. distally relative to a first section 22 located in front of the distal end section 11 of the balloon unit. An annular proximal end surface 23 of the wall 19 is sealingly anchored to a radially outer portion 24 of the distal end section 11 of the balloon unit. Similarly, the proximal chamber 18 is formed by a wall 25 concentric with the catheter tube and inclined to the longitudinal axis of the catheter tube with an annular proximal edge surface 26 sealingly anchored around a portion 27 of the catheter tube. This proximal portion 27 is located at the proximal end of a section 28 located behind, i.e. proximal to the end section 12 of the balloon unit. An annular distal end surface 29 of the wall 25 is sealingly anchored to a radially outer portion 30 of the proximal end section 12 of the balloon unit. A lumen 31 stands .F p.

Ehuru inte utvisat i figurerna står lumen 3 i kommunicerande förbindelse med en luftkälla och lumen 31 kommunicerar med en. källa, med het vätska.C L '5 via openings 32 and 33 in the wall of the catheter tube in communicating connection with the chambers 17 and 18. Although not shown in the figures, lumen 3 is in communicating connection with an air source and lumen 31 communicates with one. source, with hot liquid.
Fig. 5 visar en. modifiering av utföringsformen i fig. l.Fig. 5 shows a. modification of the embodiment of Fig. 1.
Lumen 3 för tillförsel av hetvatten till det invändiga utrymmet 5 sträcker sig ända fram till det distala partiet av utrymmet där den genomgår kateterrörets vägg vid en väggöppning 34.The lumen 3 for supplying hot water to the interior space 5 extends all the way to the distal portion of the space where it passes through the wall of the catheter tube at a wall opening 34.
Den på detta sätt tillförda heta vätskan strömmar bakåt och avgår genom en väggöppning 35 belägen vid ballongenhetens 2 proximala ände. Till denna väggöppning 35 ansluter en tillkom- mande lumen 36 för avledning av den heta vätskan. Tack vare detta utförande kan het vätska cirkuleras genom ballongenhetens invändiga utrymme 5, varvid en särskilt god termisk påverkan av kärlväggen erhålls. Detta utförande lämpar sig för ter- mokoagulering när volymen 5 är liten och vätskan kyls av människokroppen.The hot liquid supplied in this way flows backwards and exits through a wall opening located at the proximal end of the balloon unit 2. To this wall opening 35 is connected an additional lumen 36 for diverting the hot liquid. Thanks to this design, hot liquid can be circulated through the internal space 5 of the balloon unit, whereby a particularly good thermal effect of the vessel wall is obtained. This design is suitable for thermocoagulation when the volume is small and the liquid is cooled by the human body.
Enligt ett_ föredraget utförande av uppfinningen tillsätts röntgenkontrastmedel till den heta vätskan varigenom operatören lätt kan kontrollera ballongkateterns läge i blodkärlet. Den heta vätskan är företrädesvis röntgenkontraslösning med en temperatur inom ett område från ca. 50° till ca. 90° C.According to a preferred embodiment of the invention, X-ray contrast agent is added to the hot liquid whereby the operator can easily check the position of the balloon catheter in the blood vessel. The hot liquid is preferably X-ray contrast solution with a temperature in a range from approx. 50 ° to approx. 90 ° C.
De ovan beskrivna utföringsformerna av uppfinningen kan på många sätt modifieras och varieras. Exempelvis kan den heta vätskan i stället för röntgenkontrastlösning bestå av saltlös- ning, blodersättningsmedel såsom t.ex. dextran, eller andra biokompatibla vätskor. I stället för luft såsom värmeisolerande material i kamrarna 17 och 18 kan vät- eller kvävgas eller blandningar därav användas. I stället för eller såsom komple- ment till de reflekterande beläggningarna 13-16 kan de distala och proximala ändsektionerna ll, 12 innefatta partiklar av värmeisolerande material inblandade i ändsektionerna 11, 12. Ãndsektionerna 11, 12 kan alternativt vara framställda av ett böjligt material med värmeisolerande egenskaper.The above-described embodiments of the invention can be modified and varied in many ways. For example, the hot liquid instead of X-ray contrast solution may consist of saline, blood substitutes such as e.g. dextran, or other biocompatible liquids. Instead of air as heat insulating material in the chambers 17 and 18, hydrogen or nitrogen gas or mixtures thereof can be used. Instead of or as a complement to the reflective coatings 13-16, the distal and proximal end sections 11, 12 may comprise particles of heat insulating material involved in the end sections 11, 12. The end sections 11, 12 may alternatively be made of a flexible material with heat insulating characteristics.
