AI for vascular access.
Lumen is the clinical AI built where lines are placed. PICC, CVC, midline, port, and arterial line answers — sourced, bedside-ready, and trusted by the nurses and physicians who do this work every day. And it's how device makers like BD, Teleflex, and every VA manufacturer reach clinicians at the moment of decision.

For VA Clinicians
Answers at the catheter cart.
PICC nurses, vascular access RNs, interventional radiology, infusion teams, ICU, and ED — Lumen is one prompt away on the device you already have in your pocket.
Device selection
PICC vs. midline vs. peripheral IV by therapy, duration, osmolarity, and pH. Lumen factors in vessel diameter and patient history — and shows you the guideline behind the call.
Tip position & placement
Cavoatrial junction targeting, ECG-guided confirmation, post-placement chest x-ray interpretation, malposition troubleshooting.
Declotting & occlusion
Alteplase (Cathflo) dosing, dwell times, contraindications, and stepwise troubleshooting for partial vs. complete occlusion.
CLABSI prevention bundle
CDC + SHEA/IDSA bundle elements, chlorhexidine prep, dressing intervals, daily necessity review, and scrub-the-hub technique — at your fingertips.
Dwell time & removal
Evidence-based dwell limits, removal indications, line-rotation policies, and when a midline should escalate to a PICC.
Vessel health & preservation
DIVA assessment, ultrasound technique, vein selection, anticipatory planning for the next placement — preserve the patient's vessels over a hospitalization, not just a shift.

We place the lines.
We write the code.
Intracav was founded by a trauma surgeon and vascular access medical director, an Interventional Vascular Access Specialist RN, and an engineer. Vascular access isn't a vertical we added — it's where this company began.

Two meanings of vascular access.
"Vascular access" covers two distinct clinical worlds. Lumen and Intracav focus on infusion and central venous access — but a complete picture includes hemodialysis access too.
Infusion & central venous access
PICCs, CVCs, midlines, implanted ports, arterial lines, and peripheral IVs — for delivering medications, fluids, blood products, and nutrition. Governed by INS, AVA, and CDC standards. This is where Lumen lives.
See the infusion & CVAD guidelines.
Hemodialysis access
Arteriovenous (AV) fistulas, AV grafts, and tunneled dialysis catheters — the durable access that makes long-term hemodialysis possible for patients with kidney failure. Governed by the KDOQI, ESVS, and SVS clinical practice guidelines.
See the hemodialysis access guidelines.
FAQ
Common questions.
What is clinical AI for vascular access?
Clinical AI for vascular access is software that gives PICC nurses, vascular access RNs, interventional radiologists, and bedside clinicians instant, sourced answers about catheter selection, placement, maintenance, and complications. Lumen by Intracav is purpose-built for this work and shows its sources with every answer.
What can Lumen answer about PICC lines?
Catheter and lumen size selection, tip position verification, dwell time, securement and dressing intervals, declotting (alteplase) protocols, occlusion and malposition troubleshooting, CLABSI signs, removal criteria, and patient education — all sourced.
Does Lumen support CVC and central line care?
Yes — internal jugular, subclavian, and femoral CVCs. Insertion bundle, tip confirmation, maintenance, dressing changes, removal. CDC central line bundle, SHEA/IDSA recommendations, and CLABSI surveillance definitions are all in scope.
How is Intracav different from BD or Teleflex?
BD and Teleflex make vascular access devices. Intracav builds the clinical AI that sits next to those devices at the bedside. Lumen answers any question about any VA device — and any manufacturer (including BD, Teleflex, ICU Medical, Cook, Argon, Access Vascular) can publish a Lumen Extension so their product's IFU, troubleshooting, and complication management are answered in-context.
Is Lumen aligned with INS standards and CDC guidelines?
Yes. Lumen draws on the Infusion Nurses Society (INS) Standards of Practice, CDC guidance for intravascular catheter-related infections, SHEA/IDSA recommendations, and Vessel Health and Preservation frameworks. Sources are shown with every answer.
Is Lumen free for vascular access nurses?
Yes. Lumen is free for individual clinicians, including vascular access RNs, PICC nurses, infusion nurses, and ER/ICU nurses. Lumen Max adds shared workspaces and admin controls for whole VA teams; Lumen for Enterprise (via qPolicy) gives a health system a dedicated Lumen instance scoped to its own policies.
Can Lumen help with difficult IV access (DIVA)?
Yes. Lumen answers questions about vessel selection for DIVA patients, ultrasound-guided peripheral IV technique, midline vs. PICC decision-making, and when to escalate to central access — and pairs naturally with the in-depth DIVA guides on clinical-database.com.
Is Lumen HIPAA compliant?
Yes. Intracav is HIPAA compliant. Enterprise deployments include SOC 2 Type II and ISO 27001 certifications, and MagicAF supports on-premise and air-gapped deployment for organizations with strict data-residency requirements.
Built where the lines are placed.
Lumen is free for individual clinicians. Lumen Max scales to whole VA teams. And device makers can be in every answer — sourced and in-context — with Extensions.
