Description

Technical field related to the invention

The invention relates to a balloon catheter for the treatment and cleaning or removal of digestion (digestion), dilatation, fluid administration, drug administration, plaque, stenosis, blood clot (thrombus) and other extra-anatomical, extra-biological structures and structures or formations in arterial, venous and other circulatory systems in human and animal circulatory systems, as well as a thrombus catheter and the treatment process.

Known state of the art

Arterial occlusions and constrictions or strictures, venous occlusions, constrictions and venous insufficiency, constrictions in the evacuation system, whereby occlusions are defined as complaints originating from extra-anatomical and extra-biological conditions.

Arterial vasoconstriction or blood vessel narrowing or arterial occlusion are vascular diseases. These diseases are found in the carotid artery, artery under the clavicle (subclavian), in the armpit (axillary), in the upper arm (brachiel), radial artery, abdominal aorta, main pelvic vein (main iliac), iliaca externa, iliaca interna, leg veins (arteria femoralis, Sfa, profunda or DFA, popliteal aorta, anterior tibial artery, "peroneal artery", posterior tibial artery) observed. These diseases that occur in the arteries lead to a slowdown in the blood flow after the occlusion or narrowing of the area or cut it off completely, whereby after the occlusion the supply is inadequate and there is a great deal of pain at rest after the occlusion, which results in severe pain leads to a color change and ultimately leads to a loss of the limb. Venous occlusions, thrombosis or insufficiency are venous diseases. The most important vein occlusions are blood clots and insufficiency, which occur in the veins in the legs and on the abdomen. In addition to these, vein occlusions and blood clots occur in the legs and veins. Such occlusion can result in severe paralysis or death due to thrombosis or pulmonary occlusion in the brain due to advanced stage / period thrombosis, with pain, swelling and dislocation in the affected area of the blood clot or insufficiency.

Today's treatments for arterial and venous occlusions, blood clots and narrowing are as follows: Bypass surgery is a method in which endothelium in the affected area is dilated with a pt balloon dilation, aspiration, stent delivery and / or drug-filled balloons in endovascular Treatments are relieved.

The most common treatment known for the major diseases is the introduction of a balloon loaded with medication to the diseased area or area. The patient is placed on an examination table of an imaging device (angioscopy and fluoroscopy) in an imaging laboratory. The necessary antiseptic treatment is applied to the relevant area in which it is to be introduced. An intravenous cannula is placed by introducing an introducer sheath using the Seldinger technique. All subsequent process steps and all devices to be used are introduced above or within this vascular lock. A contrast medium is injected intravenously into the sheath or with the support of a catheter for diagnostic imaging, providing a vascular view under fluoroscopy. In this way, occlusions, constrictions, blood clots, stenosis, plaques, limescale deposits and / or diseased areas in the vessel can be diagnosed and recognized. This region is passed through a guidewire and / or catheter to provide complete intravenous cannulae. The guidewire is inflated with an ATM (atmosphere) pressure, useful for creating a balloon by pre-dilation, by inserting a PTA balloon catheter over the vessel into the vein, expanding the area and deflating the balloon after a desired waiting time. The same process is repeated if the expansion is not sufficient. If there appears to be sufficient space in the relevant area or area in the vein, a balloon catheter loaded with paclitaxel or other medication is introduced to the diseased area or area to be inflated at a particular time, at the point where the balloon is located covered vessel surface. This drug registration process aims to keep closures to a minimum. Despite all of these process steps, it is possible that the diseased region or area in the vein does not reach the desired width. With the help of various ablation devices, attempts are made to remove the plaque which is loaded or deposited in the vein, or to place a balloon loaded with a stent or a self-opening stent, in order to provide the optimal width in the vein and, in particular, to achieve the desired width without using an ablation method achieve.

There are some procedural issues with using one Drug-loaded balloons, which is under these treatment steps. Various chemicals are applied to the balloon to deliver the coated drug into the vein. When the balloon is removed from the sterile packaging, the surface of the guide wire comes into contact with the hands during loading and there is a liquid contact. The guides, with the help of which they are guided to the target locations by means of wires, are in contact and interact with blood due to the close contact during insertion during insertion into the veins or channels filled with blood or liquid and when passing through the valve . In all of these steps, the drug applied to the balloon is seriously damaged by these interactions and cannot be delivered to the surface of the vessel in the target dose and amount. Drugs on part of the surface of the balloon can be lost entirely.

There are some catheters that have been put on the market to solve the above problems. The catheters are compressed within the general target vessel, with balloons inflated from both sides of the discomfort area to be cleaned with an aspiration procedure, and are then transferred to the relevant location within the lumen.

European patent application no. EP2497524 describes a multi-balloon catheter for the entry of medication into the veins or veins. This invention relates to a multi-balloon catheter for delivery of a therapeutic and / or diagnostic agent into tissue, comprising a first balloon, a second balloon and a catheter with a third balloon positioned between the first and second balloons. Between the first and second balloons, the catheter has a fluid source in which a fluid is placed to inflate the first and second balloons so that a chamber is created thereon. The first balloon and the second balloon of the catheter, between which a therapeutic and / or diagnostic agent can be delivered via a fluid channel to increase the fluid pressure in the chamber, whereby fluid is transferred to the third balloon, which causes the Inflating or inflating the middle balloon the drug is targeted into the tissue with the fluid source.

In the invention of the American patent number US6485500 For the isolation of an area of a blood vessel, an embolic protection system is mentioned which has a treatable target in an interventional procedure in order to prevent vascular migration of emboli in the rest of the system. A proximally blocking balloon catheter, adapted to be confined in the blood vessel on the distal blocking balloon catheter, a distally blocking balloon catheter with proximal end holes in the catheter and a proximally blocking balloon catheter, adapted to be in the blood vessel on the proximally blocking balloon catheter is limited, as close as possible to the right and against the proximal balloon catheter in order to block the flow of fluid exchange by inflating the lumen to ensure rapid flow and it is in fluid exchange with the proximal and distal inflatable balloon blocks, includes a supply for a Inflatable fluid.

After injecting in the discomfort area delimited by inflated distal and proximal balloons, the injected drug cannot exert enough pressure. The drug, which cannot be supplied with sufficient pressure, cannot efficiently adhere to the blood clots on the surface of the vein or to the extra-anatomical and extra-biological problem areas. Therefore, after performing this procedure, which requires a quick solution, and resuming blood flow through this area after pulling out the catheter, medication cannot achieve the required benefit.

In the known prior art, various embodiments were formed by the invention; the main goal of the catheter is to create porous balloons and / or perforated catheter aspirations with hydrodynamic principles as shaft ingenuity through circulation and pressure application to the vessel surface; To provide fluid and / or liquid drug administration according to the pre-dilation or pre-dilation or post-dilation or post-dilation procedures, blood clot formation in the arteries and / or veins or veins, extra-anatomical and extra-biological structures. The cuts or ruptures (dissection) that can occur during the pre-dilation or post-dilation procedures, as well as the adhesion of plaque flaps or expansions to the surface of the vessel are said to be more efficient. For this purpose, an inflatable balloon has been constructed between the distal and proximal balloons, and hydrodynamic pressure can be applied with a perforated balloon that swells toward the surface of the vessel. Thus, in the treatment of ruptures and flaps in the veins or veins, the tedious or long-lasting pt bladder application and / or stent insertion, which perceives the vascular structure as a foreign substance, is avoided.

The invention aims at aspiration and circulation from holes located in the distal-proximal balloon space on the multi-lumen catheter shaft are arranged. The proximal and distal balloons perform the treatment according to the invention more effectively through holes on the shaft of the balloon or the catheter in different areas, but for the same purposes, namely dilation, aspiration of a liquid. According to the treatment according to the invention, the product is used in that liquid medication is added, it serves to save costs and is readily available.

The invention is a balloon catheter comprising three or two balloons on a catheter shaft. The catheter is perforated with holes of different sizes or with the same dimensions on the catheter shaft between the two balloons if the catheter has a perforated balloon in the middle and a proximal balloon of the shaft and a perforated balloon and a distal or proximal balloon. Aspiration should be performed simultaneously from the holes in the distal-proximal balloon space on the multi-lumen catheter shaft.

The balloon catheter according to the invention moves on the guide wire, which is manufactured in various diameters and sizes. The distal and proximal balloons can be inflated or inflated from the same catheter channel via a pump, an injector or a stamp. The perforated balloon or the perforated catheter structure in the middle can be inflated with a fluid and / or a liquid medicament by means of the same device from a separate channel within the catheter shaft.

Object of the invention

The main object of the invention is to predilate the arterial and venous vessels by exerting pressure on the surface of the vessel using the hydrodynamic principle, with the aim of dilatation, aspiration, fluid circulation and / or delivery of a liquid drug, clogging in the affected area or clearing and Treating extra-anatomical and extra-biological conditions, introducing a rupture or section that can occur during post-dilation procedures, and a catheter that allows plaque flaps to adhere more effectively to the vessel surface.

Another object of the invention is to provide a catheter with perforated balloons and with perforations formed on the shaft, which are formed between the inflated or inflated distal and proximal balloons, these being used to generate dilation by means of hydrodynamic pressure and contact at the target area of the vascular Lesion to be bloated.

Another object of the invention is to provide a catheter with an aspiration hole through which aspiration can be performed simultaneously through the holes in the distal proximal balloon spaces on the multi-lumen catheter shaft.

The invention was developed for three different models for the treatment of diseases caused by arterial and venous lesions, constipation, narrowing, blood clots (thrombus), plaque, stenosis, extra-anatomical and extra-biological conditions.

The treatment method sought by this invention is: aspiration and circulation processes for fluid administration, drug administration, dilatation using hydrodynamic principles in the diseased area, based on lesions, occlusions, constrictions, thrombosis, plaque, stenosis, arterial and venous vessels and extra-anatomical and extra-biological conditions or conditions using the invention.

A first embodiment of the invention is in 1 shown. The distal balloon ( 100 ) and the proximal balloon ( 102 ) arranged on the catheter shaft ( 105 ), form the perforated channel ( 101 ) arranged between the distal balloon ( 100 ) and the proximal balloon ( 102 ), out. The holes ( 103 ) on the perforated balloon ( 101 ) and the aspiration hole ( 121 ) on the catheter shaft ( 105 ) are in 2nd shown. In this embodiment, the lumen consists of a multi-lumen port (“hub”) ( 106 ) who with the catheter shaft ( 105 ) communicates, hoses ( 108 ) which are connected to the multi-lumen tube and connecting pieces ( 109 ) connected to the hoses. The connectors ( 109 ) can use a hose line for a perforated balloon ( 110 ), a guide wire hose line ( 111 ), a hose line for inflating and deflating the distal and proximal balloon ( 112 ) and an aspiration hose line ( 122 ) include. The multi-lumen catheter shaft ( 105 ) is with a valve ( 123 ), distal to the guidewire ( 111 ), designed.

He has marker tapes ( 104 ) and a soft tip ( 107 ) to mark the catheter.

As in 4th the distal balloon is shown ( 100 ) and the proximal balloon ( 102 ) designed in such a way that they are on the catheter shaft ( 105 ) are welded in advance to seal both sides of the lesion or target area. The perforated balloon ( 101 ) and / or the aspiration hole ( 121 ) can be used to deliver liquid fluid medication to the region or area that is caused by inflation or inflation of the distal balloon ( 100 ) and the proximal balloon ( 102 ) has been closed at both ends and is designed for pressure application using the hydrodynamic principle, aspiration and circulation.

The guide wire ( 115 ) of the catheter according to the invention is to the diseased area by means of a percutaneously introduced lock (inducer sheath) or via a surgically opened vessel as in the 5 , 6 , 7 shown fed.

The distal balloon ( 100 ) and the proximal balloon ( 102 ) positioned in the diseased region are inflated with a pump, syringe and indwelling devices, the distal and proximal balloons being inflated with the tubing ( 112 ) are connected, as in the 8th , 9 shown. If the remaining fluid or blood within the aspiration holes ( 121 ) is aspirated simultaneously in the region between the two balloons, a liquid liquid-drug mixture ( 118 ) from the hose line ( 110 ) pumped through the pump, injector and detector devices. This procedure also enables the circulation of fluid or fluid fluid-drug mixtures ( 118 ) between the distal balloon ( 100 ) and the proximal balloon ( 102 ) and a controlled circulation in order to exert a dilation with the hydrodynamic pressure on the vessel surface in the diseased area or in the diseased area. Due to the pressure exerted on the vessel surface using the hydrodynamic principle, a rupture or section which can occur during the pre-dilation or post-dilation procedures and adhesions or adhesions of the plaque expansions or flaps to the vessel surface more effective. In the treatment of ruptures and flaps that occur in the veins or veins due to the hydrodynamic pressure, a long-term (long-term) pt bladder application and / or stent placement, which the vascular structure as a foreign body perceives and reacts, avoided.

A second embodiment of the invention is in the 20th , 21st and 22 shown; the distal balloon ( 100 ) on the catheter shaft ( 105 ) and the perforated balloon (vein) ( 101 ). The holes ( 103 ) on the balloon and the aspiration hole ( 121 ) are in 22 shown. In this embodiment, the lumen consists of a multi-lumen port or hub ( 106 ) who with the catheter shaft ( 105 ) communicates, hoses ( 108 ) connected to the multi-lumen port and connectors ( 109 ) connected to the hoses. The catheter community ( 105 ) closes a hose line for a perforated balloon ( 110 ), a guide wire hose line ( 111 ), a hose line for inflating and deflating the distal and proximal balloon ( 112 ) and an aspiration hose line ( 122 ) with a. The multi-lumen catheter shaft ( 105 ) is distal to the guidewire ( 111 ) with a valve ( 123 ) designed.

He has marker tapes ( 104 ) and a soft tip ( 107 ) to mark the catheter.

The distal balloon or bladder ( 100 ), the advance on the catheter shaft ( 105 ) is welded on, is designed such that it closes off the distal end of the lesion or of the target area. The perforated balloon ( 101 ) and / or the aspiration holes ( 121 ) are designed such that they contain the liquid fluid-drug mixture ( 118 ) to the distally closed region or the distally limited area, apply pressure using the hydrodynamic principle and aspirate.

The guide wire ( 115 ) of the catheter according to the invention is fed into the percutaneously introduced lock or surgically controlled to the diseased area.

The distal balloon ( 100 ) is like in 23 shown by connecting the distal and proximal balloons to the tubing for inflation ( 112 ) inflated to either a pump, an injector or an indwelling device. The remaining fluid or blood is removed from the aspiration hole ( 121 ) in the region between the distal balloon ( 100 ) and the perforated balloon ( 101 ) aspirated and the fluid and / or the drug mixture ( 118 ) from the perforated balloon ( 101 ) is through the corresponding hose line ( 110 ) injected using either an injector or stamp device. This process helps in delivering the liquid-drug mixture ( 118 ) in the target zone as in 23 is shown. Due to this control it is also possible to use the perforated balloon ( 101 ) to dilate the vessel surface using the hydrodynamic pressure.

A third embodiment of the invention is in the 16 , 17th and 18th shown; the distal balloon ( 100 ) on the catheter shaft ( 105 ) has the proximal balloon ( 102 ) and the perforated catheter shaft ( 119 ). Aspiration can also be done with the Aspiration hole ( 121 ), which opens in the perforated catheter shaft.

In this embodiment, the lumen consists of a multi-lumen port ( 106 ) who with the catheter shaft ( 105 ) communicates, hoses ( 108 ) connected to the multi-lumen port and connectors ( 109 ) connected to the hoses. The catheter community ( 105 ) closes a hose line for a perforated balloon ( 110 ), a guide wire hose line ( 111 ), a hose line for inflating and deflating the distal and proximal balloon ( 112 ) and an aspiration hose line ( 122 ) with a. The multi-lumen catheter shaft ( 105 ) is distal to the guidewire ( 111 ) with a valve ( 123 ) designed.

He has marker tapes ( 104 ) and a soft tip ( 107 ) to mark the catheter.

The distal balloon and the proximal balloon ( 102 ) are designed so that they are on the catheter shaft ( 105 ) are welded in advance to complete both sides of the lesion or target area (as seen in the figures). The perforated catheter shaft ( 119 ) applies pressure and causes aspiration and circulation using the hydrodynamic principles by dispensing a liquid fluid-drug mixture ( 118 ) to both closed regions or areas.

Using the third embodiment of the invention, the guide wire ( 115 ) of the catheter into the percutaneously placed sheath or surgically opened place. The distal balloon ( 100 ) and the proximal balloon ( 102 ), which are positioned in the diseased region, are inflated with a pump, an injector and indwelling devices, the distal and proximal balloons with the tubing for inflation ( 112 ) are connected. The fluid and / or drug mixture is drawn from the perforated catheter shaft ( 119 ) through the perforated catheter shaft ( 119 ) aspirated simultaneously in the region between the two balloons, as in the aspiration flow model ( 124 ) in the remaining fluid or blood ( 19th ) in the aspiration hole ( 121 ) using the pump, injector, or director device. This procedure also enables circulation of a fluid fluid-drug mixture ( 118 ) in the region between the distal balloon ( 100 ) and the proximal balloon ( 102 ) to dilate with the hydrodynamic pressure on the vessel surface in the diseased area or in the diseased area with the help of the control of this circulation. Due to the pressure exerted on the vessel surface using the hydrodynamic principle, a rupture or section and a plaque expansion or plaque flaps, which can occur during the pre-dilation or post-dilation procedures, will adhere more effectively to the vessel surface. In the treatment of ruptures and flaps that occur in the veins or veins due to the hydrodynamic pressure, a long-term (long-term) pt bladder application and / or stent placement, which perceives and reacts the vascular structure as a foreign body, avoided.

The invention is designed for use in endovascular and / or open surgical procedures in arteries and venous vessels, the application of the invention in 13 is illustrated and the application method in 14 is illustrated.

The object of the invention is to create a zone or area in which both ends of the diseased region or area are closed or delimited by a catheter; the proximal balloon ( 102 ) is designed such that it is distal to the balloon ( 100 ) and distal to the catheter shaft ( 105 ) to complete the distal end of the lesion or target region. The hose line ( 112 ) for inflating and deflating the two balloons is connected. The aspiration hole ( 121 ), however, is designed in such a way that blood is aspirated by the interstitial fluid, whereby it is on the catheter shaft ( 105 ) at the proximal end of the distal balloon ( 100 ) is arranged and inflated. The aspiration hole ( 121 ) with the aspiration hose line ( 122 ) connected.
