Catheter Solutions


In the medical industry, finding suitable catheter solutions is an ongoing pursuit. Catheters are flexible plastic tubes that transport liquids and other substances inside or outside the body. However, the type and design of these medical devices can vary depending on the medical procedure. To meet the needs of healthcare providers, reliable design capabilities and a range of materials are essential.

The effectiveness of these devices can be significantly impacted by the choice of materials used in their construction. Catheters are available in various materials, such as flexible polymers, hydrophilic coatings, and hypoallergenic compounds, each affecting their performance. They also have different designs and functions, such as guiding catheters, microcatheters, and electrophysiology catheters.

Seisa Medical has assembled a specialized team of designers and manufacturers to create customized catheter solutions. Our experienced and knowledgeable team is skilled in developing catheters using specific materials required for various medical procedures.

What is a catheter?

A catheter is a hollow conduit that transports liquid, cameras, cables, and other elements. Plastic is the most used component for catheters, but silicon, nylon, and polyethylene are also frequent materials. Hydrophilic catheters with a slippery surface can be easily inserted and removed from the body due to their outer coating.

Physicians use catheters to drain fluids from specific organs in the body. The most frequent draining catheter is a urinary catheter, which extracts urine from the bladder when the liquid cannot leave the body naturally, however, some catheters also may transport blood and other fluids. They are prevalent in providing medical care and medical facilities, specifically for drug administration and blood transfusion.

Catheters are also the most reliable way to access internal organs without invasive procedures, and experts can insert the catheter through different body orifices and perform less harmful surgeries. Additionally, catheters can transport cameras and other exploratory equipment, allowing surgeons to use them during operations.

Catheter types

Catheter construction varies depending on its intended use. Some catheters have a bag attached for liquid extraction, drug administration, and blood transfer. Some have a needle at the end to puncture the skin and access organs, conduits, or tissues. Additionally, exploratory catheters contain cables to power the camera and transmit visual information.

Urinary catheter

Urinary catheters come in two main types: intermittent or straight catheters and indwelling catheters.

  • The intermittent catheter enters through the urethra and is easy to insert and extract, and patients may use it without medical help.
  • The indwelling catheter has a balloon at the end, keeping it in place. Depending on the patient’s condition and needs, it may stay in the body for several days, weeks, or even months.
    There are two options for this catheter: Urethral and suprapubic. For the suprapubic option, the doctor should install it through a small hole made below the belly button.
  • The Coloplast catheter is an intermittent catheter designed for one use. It contains a container for the liquid, and its materials make it easy to auto-catheterize. This design is for people who may need the procedure infrequently.

Intermittent and indwelling catheters serve the same purpose, but their usage depends on the patient’s condition and needs. Both types of catheters have different constructions for men and women to adapt to the patient’s body.

Steerable catheter

The steerable catheter is a mechanical device that physician’s control remotely, revolutionizing multiple procedures and medical specialties with non-invasive surgery.

It can enter intricate body parts without producing excessive injury, enabling cardiologists to assess vein or artery blockages and eliminate the clogging material.

Several varieties of steerable or deflectable catheters include:

  • Guiding catheter. It enters the body and provides a route for the other tubes to enter the body. Its construction provides tools for manipulating wires to guide medical procedures.
  • Diagnostic catheter. It counts on a camera to provide images and establish a diagnostic with visual information.
  • Dilation catheter (balloons). Equipped with an inflatable balloon to generate expected reactions in the intended tissue or organ.

These catheter varieties have developed since their invention in the 1970s, and the technology is now more precise and effective. Steerable catheters have applications in cardiovascular, gastrointestinal, neurovascular, and ophthalmological fields.

Other catheter types

There are catheters to transport liquids inside and out of the body. Drug administration and blood transfusion are joints. Some specialties and procedures may need specific needles, diameters, and manipulation capabilities. These specifications need clear communication between the compromised medical team and the manufacturers.

Catheters manufacturers

Catheters are essential tools in medical practice, and manufacturers must supply catheters that meet the specific medical specialties’ needs. To achieve this, manufacturers should use various materials and comply with reliable designs.

Catheter Solutions FAQ

Q. What materials are used in catheter construction, and how do they impact device performance?

A. Catheters can be constructed from various materials, such as flexible polymers, hydrophilic coatings, and hypoallergenic compounds. The material selection impacts the device’s performance, including flexibility, lubricity, and biocompatibility. For instance, hydrophilic coatings can make catheters easier to insert and remove from the body because of their slippery surface, while hypoallergenic compounds reduce patients’ risk of allergic reactions.

Q. What distinguishes intermittent from indwelling catheters, and how do they serve distinct purposes?

A. Intermittent catheters are utilized for short-term bladder drainage and are inserted and removed daily. Conversely, indwelling catheters contain a balloon at the end that retains them in place and can be used for more extended periods ranging from days to months. They serve different objectives depending on the patient’s needs and condition.

Q. How are catheters tailored to meet the specific demands of various medical procedures and specialties?

A. Catheters are tailored to meet the specific requirements of every medical procedure and specialty, such as the materials used, size, shape, and catheter functionality, among other factors. Specialized teams of designers and manufacturers collaborate to develop and produce catheters that meet the distinct requirements of each medical procedure.

Q. How is compliance with industry regulations and standards ensured during catheter production?
