The device also has the ability to deliver physician specified fluids out the distal tip with or without inflation of the balloons. ## Device Story IsoFlow is a 2.4F multi-lumen dual-balloon infusion catheter; used with 4F guide catheters and 0.010" guidewires. Operates by inflating two compliant balloons simultaneously via radiopaque fluid to isolate a vascular segment; allows localized infusion between balloons or distal tip delivery. Features hydrophilic coating; radiopaque markers for fluoroscopic positioning. Used by physicians in clinical settings to isolate treatment regions while maintaining blood perfusion via a bypass lumen. Output is the targeted delivery of physician-specified fluids; enables localized therapy while minimizing systemic exposure or maintaining distal flow. Single-use; sterile. ## Clinical Evidence Bench testing only. ## Technological Characteristics Multi-lumen dual-balloon catheter; 2.4F diameter; 120cm length. Features hydrophilic coating. Radiopaque markers for fluoroscopic visualization. Compliant balloons inflated via radiopaque fluid. Sterile, single-use device. ## 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 - DISPATCH™ Coronary Infusion Catheter ([K932616](/device/K932616.md)) - ISOLATE™ Infusion Catheter System ([K913517](/device/K913517.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Inc. | K913517 | {1}------------------------------------------------ Description of the device: The IsoFlow™ Infusion Catheter is a multi-lumen dual balloon catheter designed to isolate a specific treatment region from blood flow while allowing infusion of fluids into the region and perfusion of blood past the region. The exterior surface of the distal 120cm catheter length is treated with a hydrophilic coating. The 2.4F IsoFlow™ Infusion Catheter System is intended to be used with guide catheters 4F (0.050") and larger, along with a 0.010" guide wire for positioning the catheter in the desired region. A standard Y-adaptor RHV provides for guide wire entry and saline flush into the main guide wire / bypass lumen of the catheter. Radiopaque markers at the distal tip and between the two balloons allow for final position adjustment under fluoroscopy guidance. The two compliant balloons are inflated simultaneously using radiopaque fluid delivered via a single inflation lumen. Physician specified infusion fluid through either the labeled infusion lumen or the labeled guidewire lumen is delivered via the 1-way stopcock connection. The mixture of infusion and radiopaque agents is delivered directly to the target region between the balloons, or out the distal tip respectively. For infusion out of the sideport holes, retracting the guide wire to the radiopaque marker band proximal to both balloons allows blood to bypass the isolated tarqet region via holes connecting the guide wire / bypass lumen with the catheter exterior. Complete removal of the guidewire allows delivery from the distal tip. All components of the catheter system are provided sterile. Each device is intended for single use. Do not reuse or attempt to resterilize any component of the system. Indications: The IsoFlow™ Infusion Catheter is a multi-lumen dual balloon catheter designed to isolate a specific treatment region from blood flow while allowing infusion of fluids into the region and perfusion of blood past the region. The device also has the ability to deliver physician specified fluids out the distal tip with or without inflation of the balloons. {2}------------------------------------------------ Summary of characteristics of our device compared to the predicate device: | ISO Flow Catheter versus predicate devices | | | |--------------------------------------------|-----------------------------------------|--------------------------------------| | | DISPATCH™ Coronary
