Our biocompatible polyurethane and silicone catheters are designed to enhance patency and greatly reduce vascular damage during implantation. All of these catheter beads are accurately positioned from the tip of the catheter to find a good implantation site within the blood vessel. Beads can also be positioned to provide a secure tension ring, greatly improving the sustained patency during movement and growth.

Mouse jugular vein catheter

Mouse femoral vein catheter

The biocompatible polyurethane structure can greatly reduce vascular damage and improve patency

Mouse ductus arteriosus

We designed a biocompatible catheter for precise placement of mouse carotid arteries to greatly improve patency. Their size is suitable for fitting into small mouse blood vessels and they are equipped with sutures for easy positioning. These catheters can be used for blood pressure measurement or infusion.

Mouse tail vein catheter

The tail vein entry system consists of very small catheters and catheterization needles, which can be easily inserted into the tail vein of restrained rodents. The size allows for quick and accurate access to the tail vein, and once inserted, the flexibility can minimize vascular damage. Unlike sharp, hard needles, this catheter can move freely in the vein to ensure that the dose enters the bloodstream rather than entering surrounding tissues or returning through the insertion site. It bends naturally with the tail, reducing damage and allowing for continuous infusion or repeated push administration, thereby reducing the chance of losing the tail. These catheters are typically used for MRI, PET, and CT applications and can be easily modified to eliminate all metal components.

Micro needle

Our microcatheter simplifies the vascular pathways of small blood vessels in rodents and other small species. Sharp probes facilitate insertion, while conical tips enable fast and reliable placement of the catheter. Its features include firmly placed sutures and highly biocompatible Teflon tubes, as well as resistance to organic carriers. These catheters are connected to standard syringes or any other threaded fittings.

Butterfly Needle

These special needles (commonly known as winged infusion sets) provide a highly effective method for entering surrounding blood vessels for infusion or sampling of animals of all sizes. Compared to traditional straight needles, butterfly needles are usually shorter, with wings on both sides of the needle to improve stability, and a tube installed at the end for easy connection to the needle or collection device. Wings can provide higher grip and accuracy when handling needles. These needles come in various sizes and lengths and can be customized. They are usually injected into rodents through the tail vein of large tailed animals or in the head or great saphenous vein, and they are biocompatible and resistant to organic carriers. These needles are connected to standard needles or any other threaded connectors.

Our tapered catheter combines multiple functions to provide you with the best of both worlds performance. These catheters have thick walls outside the animal's body, which are sturdy and durable, while they are soft and easy to bend in the blood vessels. Our catheter uses a circular tip to reduce intravascular damage. Circular tips have been proven to increase vascular patency, reduce histological presentation, and provide less resistance when inserting blood vessels

Rat jugular vein catheter

Rat femoral vein catheter

The biocompatible polyurethane structure can reduce vascular damage and improve patency.

Rat ductus arteriosus

Polyester patch rat gastric duct

The gastric catheter we use for intragastric administration has Dacron patches and suture beads, which can firmly fix it at the implantation site.

Intrathecal injection catheter for rats

Our intrathecal catheter is designed specifically for implantation from the large water tank to the lumbar region. A Ga strong tube joint can greatly reduce the twisting at the outlet of the sheath space. Once installed in place, the PE coated core needle can smoothly slide out of the catheter. All catheters are exposed to ETO.

Rat T-tube

The T-tube is designed for non obstructive (straight) venous, arterial, or biliary sampling in rats and mice.

Intrathecal conduit in rodents

Catheters are used for intrathecal delivery or sampling in rodents. SAI provides a range of catheters and sleeves for collecting CSF or administering compounds to the intrathecal space of mice and rats. Our new Cisterna Magna sleeve is made of non reactive PEEK (instead of stainless steel) and features a unique non core tip to prevent unnecessary trauma. A sample size of 50 microliters is easy to collect and can be reused for up to 12 weeks.

LYMT lymphatic collection catheter

For a long time, lymphatic collection has been considered a very difficult model for laboratory research. SAI has developed a new lymphatic collection catheter that features a unique catheter design. Lymph has the same tendency to coagulate as blood, and coupled with its ultra-low production, ductal obstruction becomes a major limiting factor. SAI's new innovative technology allows for microinjection of low concentration heparin solution to accompany lymphatic collection, greatly reducing or eliminating this limitation.

Mouse bile duct

Suitable for Alzet ® The catheter pump

By connecting appropriate conduits, Alzet ® Osmotic pumps can deliver substances to the venous or arterial circulation, as well as any organ, lumen, or solid tissue entering the brain. Alzet provides a range of services related to Alzet ® Pump compatible specialized conduits can deliver to various locations with targeted delivery. Note: When subcutaneous or intraperitoneal delivery is required, no catheter is needed. These can be achieved by implanting Alzet without a catheter ® Pump to complete

Rodent endotracheal tube

These endotracheal tubes can be used for ventilation, sampling, or management, and are equipped with flexible tubes and adapters to minimize dead spaces. Three specifications are available for mice, rats, and other small rodents, and the catheter can be easily connected to anesthetic catheters. If necessary, we can trim our endotracheal tube to the appropriate size.

Pipe connection joint

It can ensure safe entry and no damage to the catheter. High quality stainless steel plugs and connectors have no burrs, which can prevent the end of the conduit from tearing during insertion and removal. No longer do we need to 'handcraft' these crucial fine components. We also provide non-metallic PEEK connectors.

Stainless steel joint

Awakening activity cage:

·Equipped with corresponding liquid swivel rings, continuous administration or blood collection can be performed on mice and rats;

·The equipment is divided into two types: rat type and mouse type, and the cage size can also be customized according to customer needs;
·Can be paired with specially designed mouse water bottles and food troughs for long-term research needs;
