Percutaneous Sheath Introducer

ARROW® PSI (Percutaneous Sheath Introducer) with ARROWg+ard® Blue Technology

The ARROW® PSI with ARROWg+ard® Blue Technology is designed to provide optimal access for hemodynamic monitoring. The hemostasis valve also allows easy access for additional devices such as thermodilution catheter or PSI companion catheter, adding up to three lumens. The sheath's inner lumen accommodates large fluid administration for fast resuscitation. The ARROW-Flex® Feature on the PSI body is designed to flex without kinking or collapsing, ensuring a patent lumen and consistent monitoring during patient movement or catheter manipulation.

The ARROWg+ard® Blue PSI catheter uses Teleflex's proprietary chlorhexidine-based antimicrobial technology proven to protect your patients from the known pathogens of Catheter- Related Bloodstream Infections (CRBSIs).

The ARROW® ErgoPack® System provides 30 essential tools systematically organized for procedural ease. The ErgoPack® System integrates the latest infection prevention and safety measures recommended by the CDC, SHEA/IDSA, IHI, JCAHO, NHSN and OSHA into one convenient bundle.

Frequently Asked Questions

Can we use the Side Port of an indwelling PSI to do blood draws?

Mechanically, PSIs are a single-lumen system indicated for venous access. Clinicians should follow the same techniques used with any CVC to maintain patency. If the catheter through the valve is withdrawn and the PSI is left indwelling, an obturator must be used to guard against any potential bleeding or air embolism.

What is the function of the obturator on the ARROW® PSI products? Is there a danger to the patient if the obturator is not placed into the Introducer upon removal of an indwelling catheter? Are these obturators available separately?

The hemostasis valves in an ARROW® PSI must be occluded at all times to minimize the risk of patient air embolism or hemorrhage. If catheter introduction is delayed, or the catheter is removed, temporarily cover valve opening with sterile-gloved finger until a catheter or obturator is inserted. Use an ARROW® Obturator, either included with the introducer or sold separately, as a dummy catheter with hemostasis valve/side port assembly and sheath. This will ensure that leakage does not occur and the inner seal is protected from contamination. Sold separately: Product #AO-09000 ARROW® Hemostasis Valve Short Obturator.

Can we use an ARROW® PSI with a power injector? What is the maximum pounds per square inch (psi) that can be injected through an ARROW® PSI?

The ARROW® PSI is not indicated for pressure injection, and is not designed to withstand the higher pressures associated with contrast used during CT scans. Internal testing has shown the ARROW® PSI is capable of pressure up to 45 psi. The minimum strength of 45 psi allows for hand injections performed with a 10 cc or larger syringe, as indicated. ARROW® PSI can also be used with most rapid infusers which typically utilize 5.8 psi or 300 mmHg (millimeters of mercury). For more information, contact your rapid infuser manufacturer.

Are ARROW® PSIs MRI compatible? Is the ARROWg+ard® Antimicrobial Technology with chlorhexidine and silver sulfadiazine also MRI compatible?

Yes. ARROW® PSIs are MRI compatible. The catheters are made entirely of polyurethane and they contain no wire or ferromagnetic material. The catheters have been tested to be compatible to use with an MRI machine. Additionally, chlorhexidine and silver sulfadiazine are organic antimicrobial compounds that do not contain wire or ferromagnetic materials, and are compatible to use during an MRI procedure.

Can the ARROW® PSIs be exposed to alcohol or acetone?

ARROW® PSIs can be exposed to alcohol, but the length of the exposure is key. Brief exposure at the insertion site or during a dressing change will not compromise the integrity of the catheter. You should allow skin preps to completely dry per the manufacturer's Instructions For Use to minimize exposure. Prolonged exposure to alcohol, like soaking the catheter in alcohol for a few days, is not recommended and long periods of exposure to alcohol can weaken the structure of the polyurethane. Ethanol lock solutions have not been tested by the manufacturer, and no specific recommendation can be made by the company. Do not use acetone on the catheter surface. Acetone may be applied to skin but must be allowed to dry completely prior to applying dressing.

What are the recommended temperature storage conditions for ARROW® PSIs products?

It is generally recommended that ARROW® PSI products should be stored between 20 – 25°C (68 – 77°F). The kits should not be exposed to freezing temperatures at 0°C (32°F) or below nor excessive heat 40°C (104°F) or above. The temperature controls are to ensure the quality, functionality, and safety of our product. The temperature parameters are based on internal testing and individual kit items. Check your product lidstock for more information.
