AI Technical Summary
Existing atrial septostomy procedures face complications such as prolonged procedure times, operator-dependent variability, increased risk of complications like perforation, and the need for multiple invasive steps due to imprecise puncture methods, particularly when using larger catheters or implants like stents that can cause thrombosis and infection.
A steerable support sheath at the distal end of the catheter provides precise, anatomically optimal puncture at the atrial septum, reducing the need for additional imaging and catheters, and offering stability and guidance for subsequent cardiac interventions.
This approach reduces procedure duration, minimizes complications, enhances patient safety, and allows for efficient, single-system performance of multiple cardiac interventions by ensuring precise and stable access to the left atrium.

Abstract
Description
1 TARIFF ATRIAL SEPTOSTOMY CATHETER TECHNICAL FIELD The invention aims to improve atrial function in cardiovascular treatment methods and angiography units. In procedures requiring septostomy, 5 are provided to facilitate the septostomy. It is related to the catheter that was inserted. STATE OF THE ART To create a connection between the heart chambers, a bridge is built between the body chambers. There are several medical conditions that are treated by creating an opening. Heart left It has an interatrial septum or wall that separates the upper atrium and the right atrium. Some 10 To reduce left atrial pressure in heart failure patients, blood is drawn from the left atrium It is necessary to allow blood to flow into the right atrium. Similarly, congenital heart diseases and some other heart diseases and conditions such as pulmonary hypertension It can be treated by creating an interatrial opening; however, high right-sided pressure To reduce it, a right-to-left shunt needs to be created. 15 In left heart catheterization procedures, atrial catheterization is performed using a mechanical or radiofrequency needle. The method of puncturing and passing the septum appears to be becoming more common. Small For catheters of larger diameters, this procedure is generally simpler. However, for the interatrial septum... when a larger catheter is inserted, allowing the catheter to pass through the septum It is necessary to widen the drilling site. The initial widening of the septal drilling site is 20 Current methodologies for this involve using a dilator to open the access location, or This involves inflating the balloon. In this case, the doctor needs to change the instruments several times. This is necessary. However, this has an undesirable effect on the tissue. Creating permanent openings along the interatrial septum, and particularly along the fossa ovalis, can be done in various ways. Medical device technologies have been developed. Creating a hole in the septum in one procedure 25 A balloon is used for this. However, a hole created in this way opens It has been observed that it may not remain open or may close spontaneously after a while. 2 Several other devices have been identified that could provide a temporary solution beyond using balloons. Placing a stent in the interatrial septum allows blood to flow through the opening to the other atrium. by allowing blood to flow and reducing atrial pressure, high pressure in one atrium It is used as a treatment. A heart surgeon, blood flow between the atria In an effort to control the quantity, stents were made in specific predetermined sizes. It inserts a stent or stent-type structure to keep the hole open. The device uses a stent, a type of valve, to help control the direction of blood flow. These devices may contain substances that can promote thrombosis. Significant disadvantages of these devices include the potential for causing thrombosis. They are permanent implants that are potentially susceptible to infection. In addition, these types of implants require blood-thinning medication regimens. This also leads to other medical 10 This causes problems. These implants are also used in conjunction with other necessary surgical treatments. It also causes other types of problems. The invention aims to eliminate the aforementioned disadvantages and contribute to the relevant technical field. It was developed to offer an innovative solution. THE PURPOSE OF THE INVENTION 15 The main goal of the invention is to reduce complications of atrial puncture and to make the procedures easier. by ensuring safety, the puncture is performed at the optimal point of the atrial septum. The goal is to shorten the processing time by performing this action. As evidence that the stated purpose is achieved, the catheter that is the subject of the invention can be guided. Thanks to its supportive structure, it is positioned at the most anatomically optimal point of the atrial septum. It allows for access with high precision. In traditional methods... Transseptal puncture performed with image-guided manual transfer. These procedures carry operator-dependent variability and a risk of complications. Our invention... Thanks to this, the steerable support sheath at the distal end of the catheter provides optimum support to the septum. It allows for an approach at an angle and performs septal puncture at the anatomically safest point, 25°. This allows for the delivery of iatrogenic gases into the aorta or pericardial space. It reduces the risk of serious complications such as perforation, while shortening the duration of the procedure. It improves patient safety and reduces operator dependency. The aim of the invention is to reduce the need for additional invasive procedures. 3 As evidence that the aforementioned goal has been achieved, traditional transseptal puncture is used. In these procedures, ascending septum is frequently used to determine the position of the atrial septum. An anatomical reference point is created by placing a pigtail catheter in the aorta. This addition... The invasive procedure both prolongs the procedure time and requires additional needle insertions. This increases the risk of complications. In the catheter system we developed, however, there are 5 Thanks to its steerable distal end structure and support sheath, the septum's anatomical structure The location can be directly localized, which eliminates the need for additional catheters or imaging. This eliminates the need for it. Thus, patient comfort and procedure efficiency are improved. As the number of infections increases, the level of invasiveness decreases significantly. Another aim of the invention is to improve atrial fibrillation ablation and mitral balloon valvuloplasty. The goal is to provide catheter support during the procedures. As evidence that the aforementioned objective is achieved, the catheter design is transseptal only. not only for the puncture itself, but also for further cardiac interventions that follow the procedure. It provides mechanical and directional support, especially in atrial fibrillation ablations. Ensuring safe and stable access to the left atrium is of paramount importance. 15 Similarly, in mitral balloon valvuloplasties, the balloon catheter must be in the correct position. Ensuring that the holding and passing maneuvers are carried out in a controlled manner increases the success rate. These are the key factors influencing the process. The developed catheter can remain in a fixed position. The adjustable support sleeve provides the operator with stability and safety throughout the operation. This provides 20 features that classic introducer cases cannot provide. It offers both guidance and support functions. Another aim of the invention is to create a multi-purpose system for post-transseptal puncture procedures. It provides the possibility of being used as an access platform. As evidence that the aforementioned objective is achieved, the internal structure of the catheter conforms to the standard 0.035. 25 inch guide wires and compatible with balloon / dilator systems of different diameters. It is designed in such a way that the device is used not only for the puncture procedure, but also... It also serves as an access platform for initiatives to be undertaken after the puncture in a timely manner. This results in ablation directed into the left atrium via a catheter. Catheters, balloon valvuloplasty devices, or biopsy tips are easily delivered. Thus, multiple interventional procedures can be performed through the same system throughout the procedure. 30 This is done by reducing device changes and intravascular maneuvers, thereby both 4 It both increases security and saves time. This aspect of the device is very advantageous. It is made possible to use it as a functional system.
