Description

Tapered Coronary Sinus Vein Balloon
The taper balloon of coronary sinus vein has the technical field of health and medical equipment. In Cardiac Resynchronization Therapy (CRT), after insertion of the coronary sinus lead and lead analysis, the guide wire and sheathe must be removed. However, sometimes, when removing the guide wire and sheathe, the lead is displaced or removed that it is important to put it in the right place. The taper balloon of the coronary sinus vein has a fixed distal wire that passes through sheathe. According to the operator’s opinion and using the maneuver, the balloon is inflated at the proximal or distal lead to jail the lead at the balloon site and prevent it from displacement. Then the guide wire and sheathe are removed by ensuring the lead analysis. Using the taper balloon of coronary sinus vein, the procedure time, X-rays and costs are reduced.
Cross Reference to Related Application
This application claims the benefit of priority to an Iran patent application having serial number 139750140003004780 filed on Aug. 29, 2018, which is incorporated by reference herein in its entirety.
The innovation refers to an advantageous technology in a dilatation balloon assembly and particularly to a novel improvement in variable distention angioplasty balloon assembly.
The first pacemakers made, had the size of a table-clock and a service life shorter than 12 months. However, the idea of using an electrical device to provide for a regular heart beat was suggested by Paul Zoll in 1952.
The initial design of this system represented a device with two wires to be connected to the patient's belt. The device would be connected to an electricity socket and therefore, heart of the person having suffered a cardiac attack would be stimulated by electrical shock. This would often result in resumption of normal activity of the heart. This almost effective device would initially be used under emergency conditions; until batteries were added to the systems in 1958 and this converted the pace-makers into portable systems which facilitated mobility of the patient. The first implantable pacemaker was invented by William Cardac and Willson Gretback and used for a living person in 1960. Its battery had a service life of 12-18 months.
The modern technique for implanting a pacemaker into the heart was innovated by Simon Foreman in 1960. Instead of opening the patient's Chest he passed the leads through the veins and guided toward cardiac ventricles. Placement of the leads into ventricles reduced the voltage needed for adjustment of heart beats and this provided for a longer utilization of the pacemaker. Though this method was not utilized broadly at first, cardiologists started using the method later in 1960's. Along with the advancement made in respect of regulating leads, which consist of some wires depending on kind of lead covered with multiple layers of insulating materials and placed in heart through a vein, substituted the primary leads that would be connected to the outer surface of heart. Nowadays, pacemakers and leads are implanted without the requirement of opening the chest. Some pacemakers are temporary and they are normally used for an immediate establishment of hemodynamic stability of heart; or they may be used where a probability exists for arising of a brachycardia amidst the surgical Operation.
The most simple kind of pacemakers is referred to as single chamber pacemaker as this is connected to only right atrium or right ventricle by a lead. A dual Chamber pacemaker has two leads, one of which is placed into right atrium and the other one into right ventricle. This kind of pacemaker can stimulate two chambers. An ICD (Implantable Cardioverter Defibrillator) has a wire which is placed into right ventricle and it is principally used for quick ventricular arrhythmia. There are also more recent pacemakers which are Wireless and they are placed into the heart through feet veins in the way similar to angiography. Currently the aforesaid pacemakers (wireless) are supplied in the form of single chamber pacemakers only.
There is some kind of double ventricle, triple chamber pacemakers referred to as cardiac resynchronization therapy defibrillator (CRT-D) or Cardiac resynchronization therapy pacemaker (CRT-P) which are used in treatment of Cardiac insufficiency.
A lead is placed into right ventricle with another lead placed into right atrium. These are mostly active- fixation and steroid-eluting leads. A third lead is placed at Coronary sinus. This latter lead is curved, tined or steroid-eluting to pace the left ventricle.

The catheter includes a connection between the distal balloon and the central wire, which shows the minimum resistance to torsion in the central wire when the central wire is rotated towards the balloon and the balloon is inflated.

This summary is intended to provide an overview of the subject matter of the present disclosure, and is not intended to identify essential elements or key elements of the subject matter, nor is it intended to be used to determine the scope of the claimed implementations. The proper scope of the present disclosure may be ascertained from the claims set forth below in view of the detailed description below and the drawings.
According to some exemplary embodiments, the taper balloon of coronary sinus vein has the technical field of health and medical equipment. In Cardiac Resynchronization Therapy (CRT), after insertion of the coronary sinus lead and lead analysis, the guide wire and sheathe must be removed. However, sometimes, when removing the guide wire and sheathe, the lead is displaced or removed that it is important to put it in the right place. The taper balloon of the coronary sinus vein has a fixed distal wire that passes through sheathe. According to the operator’s opinion and using the maneuver, the balloon is inflated at the proximal or distal lead to jail the lead at the balloon site and prevent it from displacement. Then the guide wire and sheathe are removed by ensuring the lead analysis. Using the taper balloon of coronary sinus vein, the procedure time, X-rays and costs are reduced.
Some kind of pacemakers known as double atrium triple chamber pacemakers or Cardiac resynchronization therapy (CRT) pacemakers, are used in treatment of Cardiac insufficiency. A lead is placed in right ventricle, another lead in right atrium and the third lead in Coronary Sinus. Much progress has taken place in designing leads to substitute the straight and curved tip leads.
Modern leads are tined or active stabilization leads and they are more commonly used nowadays. They provide for a more reliable connection to cardiac tissue so that dislocation of the lead is prevented.
This kind of active leads are used in right atrium and ventricle. However Coronary Sinus lead cannot be activated in the same way as those of atrium and ventricle. Coronary Sinus leads are mostly curved and only some of those leads are tined or steroid-eluting to pace left ventricle.
To place a Coronary Sinus lead, a sheath is required to be placed first. In case the tip of sheath rests on the proper location, then 0.014-in guide-wire is placed at the proper point on a branch of Coronary Sinus and subsequently the lead runs over the guide-wire. Sometimes the guide-wire is dislocated when the lead is running over the guide-wire whereupon it should be retried or instead, one may displace or even substitute the guide-wire with another one so that the lead is properly located with the help of guide-wire. There are accessions when the lead is displaced at the moment of removing the sheath after the coronary sinus lead has been properly placed and it has been checked by using an analyzer. There are even the occasions when tip of the lead is displaced when removing the sheath after we have properly placed the coronary sinus lead and have checked it by using an analyzer, and there are even the occasions when tip of the lead is displaced after the sheathe has been removed and we are trying to remove the guide (Stylet) . The aforesaid displacements make us place the sheathe again with the help of guide-wire and repeat the procedures completely.
Purpose: It is to prevent displacement of lead or tip of coronary sinus lead when removing the sheath or guide (Stylet) and hence to prevent repetition of sheath placement and other procedures.
Tapered coronary sinus vein balloon is a catheter balloon with a length of 70 to 135 cm made of a polymer-polyethylene-polypropylene-polyurethanes-nylon-silicon-pebax or a combination of it, which has a hydrophilic or non-hydrophilic guidewire at the distal end with a straight or cure or shapeable head with a length of five to twenty mm and a diameter of 0.014 or 0.010 inches, and there are two types of (Compliance) balloon or (semi or non-compliance) balloon with a pressure of 6 to 24 atmospheres and length of the balloon is 6 to 30 mm and a diameter of 1.50 to 8.00 mm, which have no the same diameter (Tapered) at the proximal end and the distal end, and they are different in the lower diameters from 0.125 mm (such as 1.50 in the distal and 1.75 in the proximal) and in the higher diameter to 0.05 mm (such as 6.00 in the distal and 6.50 in the proximal), and always the Proximal part of the balloon is more than the Distal part of the balloon.
The tapered balloon has at least one marker in the middle of the balloon or two markers at the proximal and the distal ends of the balloon that the markers are opaque and approximately one to two millimeters in diameter, indicating position of the Proximal end and the Distal end or the middle of the balloon at the time of fluoroscopy. The balloon (Shaft) has a (Lumen), associated with a (Hub) at the Proximal end and with a balloon at the Distal end.
(Hub) is embedded at the Proximal part of the balloon, which is connected through the lumen inside the catheter shaft to the balloon's lumen, and balloon's inflation/deflation can be done with the help of a syringe or special medical instruments (Inflator) through the connection to the Catheter Hub.
1- A better body balloon support for lead when passing beside the balloon.
2- Prevention of movement of guide-wire when passing the lead under the conditions that the balloon in inflated and guide-wire is jailed.
3- Prevention of displacement of lead when the lead is jailed and we intend to remove sheath and guide-wire.
4- Reduction in procedure time because of prevention of probability of displacement of lead and due to prevention of a repeated procedure for placement of sheath.
5- Reduction in fluoroscopy time, X-ray and sometimes in costs

DETAILED DESCRIPTION OF THE DRAWINGS
In the following detailed description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant teachings. However, it should be apparent that the present teachings may be practiced without such details. In other instances, well known methods, procedures, components, and/or circuitry have been described at a relatively high-level, without detail, in order to avoid unnecessarily obscuring aspects of the present teachings.
The following detailed description is presented to enable a person skilled in the art to make and use the methods and devices disclosed in exemplary embodiments of the present disclosure. For purposes of explanation, specific nomenclature is set forth to provide a thorough understanding of the present disclosure. However, it will be apparent to one skilled in the art that these specific details are not required to practice the disclosed exemplary embodiments. Descriptions of specific exemplary embodiments are provided only as representative examples. Various modifications to the exemplary implementations will be readily apparent to one skilled in the art, and the general principles defined herein may be applied to other implementations and applications without departing from the scope of the present disclosure. The present disclosure is not intended to be limited to the implementations shown, but is to be accorded the widest possible scope consistent with the principles and features disclosed herein.
For purposes of reference, it should be understood that the techniques and systems disclosed herein are applicable to coupled motion in a wrist; however, the techniques and systems may be adapted to a number of other applications.
To Place the coronary sinus lead, one should first place a sheath the sheathe is to be placed at the beginning of coronary sinus vein with the help of a 0.033 in guide-wire and a catheter while contrast material is injected as well.
When sheath tip has been placed at the proper point, first the 0.014-in guide-wire is placed in a branch of coronary sinus with the help of catheter. In case the operator intends to jail the distal part by the balloon, then tapered coronary sinus vein balloon should be guided by support from the guide-wire so that it is placed beside guide-wire. Then; the balloon is to be inflated while it jails the guide-wire. After we have ensured that the guide-wire has been jailed by the balloon, we may pass the coronary sinus lead over the jailed guide-wire until it is guided to the intended point. Most often it is happened that the guide is dislocated when we are passing the lead through the curve or bifurcation of the vein.
However, there is no possibility for us to displace the guide-wire under these circumstances because of jailing of the guide-wire. Therefore, the lead is guided to the end of balloon, when we may guide the deflated balloon and lead with the support of guide and balloon to the intended point and after all, we way inflate the balloon when every analysis has been made on the lead by the system in the may thut the balloon is jailed. Under these conditions, we way first remove the sheathe and then the guide (stylet).
This method doesn't require to passing of a second guide-wire for guiding the balloon. At the same time, the balloon's shaft provides a better support for passing the coronary sinus lead over the guide-wire. Furthermore, when the operator intends to jail proximal (beginning) part of the lead, the balloon my be guided through the sheath to the beginning of the vein after the lead has been passed and positioned appropriately.
Then, after lead analysis we may inflate the balloon. We may then remove the sheath and stylet and finally remove the deflated balloon slowly. After analysis of coronary sinus lead, we may fix the same at the point of incision with the help of Anchored-sleeve.

Examples
According to one or more exemplary embodiments of the present disclosure:
1- The balloon catheter in addition to the coronary sinus can be used as a trap technique in the cardiovascular and peripheral vessels.
2- in another example, When, after passing the guide wire to the desired area, the guide wire does not provide the necessary support for the passage of the lead to the intended point, it is possible to lead the taper balloon to the end of the branch and then conduct the guide wire and lead with balloon catheter support easily to the point where the balloon catheter is located.
3- in another example, Fixing or trapping the lead occurs when the lead is trapped by the taper balloon. In this case, after temporary fixing or trapping of the lead, sheathe and guide wire can be removed without displacing the lead from the point it is trapped and finally, the balloon catheter is removed.
Tapered coronary sinus vein balloon has its application in cardiac resynchronization therapy defibrillator (CRT-D) or Cardiac resynchronization therapy pacemaker (CRT-P) where it prevents displacement or removal of the lead upon removing the sheath and guide-wire (stylet) after the lead has been jailed.
