The pre-loaded Fathom and Transend Guidewires can be used to selectively introduce and position the microcatheter in the peripheral vasculature. The microcatheter can be used for controlled and selective infusion of diagnostic, embolic, or therapeutic materials into the vessel. ## Device Story Direxion and Direxion HI-FLO Torqueable Microcatheters are peripheral vascular catheters designed for selective infusion of diagnostic, embolic, or therapeutic materials. Devices feature hydrophilic-coated distal shafts, radiopaque markers for fluoroscopic visualization, and steam-shapeable distal tips. Available in small (2.5F-2.7F) and large (2.9F-3F) lumen configurations to accommodate steerable guidewires (Fathom-16, Transend 14/18). Operated by physicians in clinical settings under fluoroscopic guidance. Pre-loaded guidewire configurations facilitate navigation through distal, tortuous vasculature. Output is the delivery of therapeutic or diagnostic agents to specific vessel sites. Benefits include improved pushability, steerability, and torqueability for accessing challenging anatomy. ## Clinical Evidence Bench testing only. No clinical data provided. Performance testing included microcatheter luer compatibility, ID/OD verification, coating integrity, particulate evaluation, tensile strength, corrosion resistance, kink resistance, distal tip flexibility, proximal shaft pushability, torsional strength, maximum infusion pressure, leakage testing, embolic/PVA compatibility, chemical compatibility, guide catheter/guidewire/accessory compatibility, shelf life, packaging, sterilization, and biocompatibility. ## Technological Characteristics Peripheral vascular microcatheters with hydrophilic coating and radiopaque distal markers. Available in small (2.5F-2.7F) and large (2.9F-3F) lumen sizes. Steam-shapeable distal tips. Proximal end features standard luer with rotating hemostatic valve or Y-adapter. Materials and sterilization methods are consistent with predicate. No software or electronic components. ## Regulatory Identification A continuous flush catheter is an attachment to a catheter-transducer system that permits continuous intravascular flushing at a slow infusion rate for the purpose of eliminating clotting, back-leakage, and waveform damping. ## Predicate Devices - Renegade HI-FLO Microcatheter ([K100892](/device/K100892.md)) ## Reference Devices - Fathom-16 Steerable Guidewire ([K111485](/device/K111485.md)) - Transend 14 Steerable Guidewire ([K971254](/device/K971254.md)) - Transend 18 Steerable Guidewire ([K964611](/device/K964611.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The pre-loaded Fathom and Transend Guidewires can be used to selectively introduce and position the microcatheter in the peripheral vasculature. The microcatheter can be used for controlled and selective infusion of diagnostic, embolic, or therapeutic materials into the vessel. #### Device Description The Direxion Microcatheter is available in small and large lumens. The Direxion Torqueable Microcatheter (Direxion) is a small lumen microcatheter with a distal outside diameter of 2.5F (0.85 mm), and a maximum outside diameter of 2.7F (0.95 mm). It has an inside diameter of 0.021 in (0.5 mm) minimally in the proximal and distal regions. The microcatheter lumen is able to accommodate steerable guidewires with diameters ≤ 0.018 in (0.47 mm). The Direxion HI-FLO Torqueable Microcatheter (Direxion HI-FLO) is a large lumen microcatheter with a distal outside diameter of 2.9F (1.00 mm), and a maximum outside diameter of 3F (1.05 mm). It has an inside diameter of 0.027 in (0.6 mm) minimally in the proximal and distal regions. The microcatheter lumen is able to accommodate steerable guidewires with diameters ≤ 0.021 in (0.53 mm). The Direxion and Direxion HI-FLO Microcatheters are available in a variety of tip shapes (Straight, Bern, Swan Neck, and J Shape) to aid with accessing challenging anatomy. The distal outer surface of the microcatheter is coated with a hydrophilic coating. A radiopaque marker is located at the distal tip to facilitate fluoroscopic visualization. Some Direxion Microcatheters have a second marker 3 cm proximal to the first marker. The distal tip of the microcatheter is steam shapeable. The proximal end incorporates a standard luer with rotating hemostatic valve (RHV) or Y-adapter. The Direxion and Direxion HI-FLO Microcatheters are available with the following preloaded guidewires: #### Fathom-16 Steerable Guidewire (K111485) - 0.016 in (0.41 mm) diameter; 140 or 180 cm lengths #### Transend 14/18 Steerable Guidewires (K971254 / K964611) - 0.014 in (0.37 mm) or 0.018 in (0.47 mm) diameters; 135, 165 or 190 cm lengths The guidewires have a hydrophilic coating to provide lubricity, which aids in the navigation of distal, tortuous vasculature. The guidewires are radiopaque to allow for visualization under fluoroscopy and the tips are shapeable. Accessories may include a RHV or Y-adapter, steam shaping mandrel, microcatheter introducer, quidewire introducer and torque device. {2}------------------------------------------------ K132947 p. 3 of 3 #### Comparison of Technological Characteristics The Direxion and Direxion HI-FLO Torqueable Microcatheters are similar in fundamental design, function, device materials, packaging, sterilization, operating principle, intended use / indication for use and fundamental technology as the predicate device, Renegade HI-FLO Microcatheter. The modifications from the predicate device include changes to catheter design and materials for added pushability, steerability, and torqueability in accessing the treatment site. In addition the microcatheters are provided with preloaded guidewires for physician convenience. A minor change was made to the packaging design to accommodate the preloaded guidewires. #### Performance Data The following bench testing was conducted for design elements and performance characteristics deemed appropriate to demonstrate equivalence to the predicate device. The Direxion and Direxion HI-FLO Torqueable Microcatheters including packaging met the predetermined acceptance criteria ensuring substantial equivalence to the predicate device. No new safety or performance issues were raised during testing. - Microcatheter Luer Compatibility � - Microcatheter ID / OD Verification . - Catheter Usable Length . - .
