Medical Steerable/Deflectable Catheters

A steerable/deflectable catheter is a medical device used to perform diagnostic or therapeutic procedures within the human body. It’s made of a soft material that passes fiber optics, cables, or other tools inside the catheter so doctors can view or manipulate specific areas.

Steerable/deflectable catheters are commonly used for endoscopy, interventional procedures or treatments, such as gastroscopy, enteroscopy, cardiac catheterization procedures, etc. Its flexibility and maneuverability enable doctors to accurately navigate to the target area and perform necessary operations.

This conduit is usually made up of multiple joints and can be operated with an external joystick or controller. The doctor can adjust the bending angle, direction and depth of the catheter through the controller to achieve the desired position and angle.

The use of steerable/deflectable catheters can reduce surgical trauma and pain and improve surgical accuracy and safety. It is widely used in the medical field and is constantly developed and improved to meet different clinical needs.

FEATURES

Medical Steerable/Deflectable Catheters

Medical steerable/deflectable catheters have a wide range of applications in the medical field. Here are some common application areas:

Endoscopy: Steerable/deflectable catheters are commonly used for endoscopy such as gastroscopy, colonoscopy, and bronchoscopy. Doctors can introduce the lens into the body through the catheter to observe and examine lesions or abnormalities in the digestive tract, respiratory tract and other organs.

Interventional surgery: Steerable/deflectable catheters play a key role in interventional surgery. For example, in cardiac catheterization surgery, doctors can introduce instruments into the heart blood vessels through the catheter to perform angioplasty, vascular stent implantation and other treatment operations.

Neurosurgery: Steerable/deflectable catheters are also used in neurosurgery. For example, in the treatment of cerebrovascular diseases, doctors can introduce instruments into the cerebral blood vessels through catheters to perform procedures such as blood vessel embolization and blood vessel repair.

Urology: Steerable/deflectable catheters are commonly used in urology surgeries for the examination and treatment of organs such as the urethra, bladder, and ureters. For example, during bladder tumor resection, doctors can introduce instruments through a catheter to remove the tumor and repair the lesion.

Gynecological surgery: Steerable/deflectable catheters are also used in gynecological surgery. For example, in the treatment of endometriosis, doctors can introduce instruments through a catheter to perform procedures such as endometrial ablation and endometrial cauterization.

Steerable/deflectable catheters are widely used in the medical field and can be used for various endoscopic examinations, interventional surgeries and therapeutic procedures, providing doctors with more accurate, safe and effective diagnosis and treatment means.

Steerable Catheter Capabilities for Medical

Medical steerable catheters have a variety of functions and applications, here are some common ones:

Bending and deflecting functions: The steerable catheter can be bent and deflected via an external joystick or controller to adapt to different anatomy and operating needs. This feature allows the catheter to pass through tortuous passages or organs to reach the target area.

Navigation and positioning functions: The steerable catheter can accurately navigate to the target area and perform necessary operations. The doctor can control the movement of the catheter through the controller and guide it to the area that needs examination or treatment for accurate positioning and positioning.

Vision and observation functions: Steerable catheters are usually equipped with optical fibers or cameras that can transmit image or video signals, allowing doctors to observe and examine the target area in real time. This helps doctors make accurate diagnoses and assessments.

Operation and treatment functions: The steerable catheter can deliver various tools and instruments for operation and treatment. Doctors can introduce tools such as blades, pliers, and lasers through the catheter to perform cutting, clamping, cauterizing and other treatment operations.

Sampling and testing functions: The steerable catheter can be used for sampling and testing. Doctors can introduce sampling equipment through the catheter to collect tissue samples or body fluid samples for pathological examination, bacterial culture, genetic testing, etc.

Medical steerable catheters are used in a wide range of applications, including but not limited to the following areas:

Endoscopy: such as gastroscopy, colonoscopy, bronchoscopy, etc., used to examine lesions or abnormalities in the digestive tract, respiratory tract and other organs.

Interventional surgery: such as cardiac catheterization surgery, vascular interventional surgery, etc., used for angioplasty, vascular stent implantation and other treatment operations.

Neurosurgery: such as cerebrovascular surgery, spinal surgery, etc., used for therapeutic operations such as vascular embolization and nerve stimulation.

Urology: such as cystoscopy, ureteral surgery, etc., used for the examination and treatment of urethra, bladder, ureter and other organs.

Gynecological surgeries: such as endometrial ablation, endometrial cautery, etc., for the treatment of endometriosis.

In general, medical steerable catheters have a variety of functions and applications and can be used for various endoscopic examinations, interventional surgeries and therapeutic operations, providing doctors with more accurate, safe and effective diagnosis and treatment methods.

Medical steerable catheters have the following properties and common materials:

Flexibility and flexibility: Steerable catheters need to have good flexibility and flexibility to adapt to different anatomy and channels. Common materials include polyurethane, silicone, polyethylene, etc.

Strength and durability: While steerable catheters need to be flexible, their materials also need to be strong and durable enough to withstand the forces and pressures of manipulation and treatment. Common materials include stainless steel, nickel-titanium alloy, etc.

Biocompatibility: The materials of medical steerable catheters need to have good biocompatibility to avoid irritation or adverse reactions to human tissues. Common materials include polyurethane, silicone, etc.

Visibility: Steerable catheters are often equipped with fiber optics or cameras to deliver image or video signals, allowing doctors to observe and examine the target area in real time. Therefore, the catheter material needs to have good transparency or light conductivity. Common materials include optical fiber materials, glass, etc.

Maneuverability: The material of the steerable catheter needs to have good maneuverability so that the doctor can accurately operate and control the catheter through an external joystick or controller. Common materials include polyurethane, silicone, etc.

Cleanability and Disinfectability: Medical steerable catheters need to have good cleanability and disinfectability to ensure hygiene and safety before and after use. Common materials need to be able to withstand routine cleaning and disinfection methods.

Custom liners

Braid- or coil-reinforced composite shafts featuring design enhancements such as Flex Tube technology

Pull wires
