A New Surgical Architecture for the Abdomen:
Open-like Access, Minimally Invasive
Built to solve the limitations of current robotic systems
Designed to solve the limitations of current robotic systems
The Majority of Abdominal Surgery Remains Open
Open surgery persists despite higher trauma, longer recovery, and increased cost
Robotics transformed pelvic surgery
Adoption drops sharply in abdominal surgery
High-volume abdominal procedures still performed open
Driven by system limitations
Robotics fails to address the majority of abdominal surgery.
New systems increase competition, not capability, as they share the same underlying architecture
Current Robotic Systems Were Not Designed for the Abdomen
Core architectural limitations restrict access and scalability
Designed for confined anatomy, not the full abdomen
External arms create collisions and procedural complexity
Limited reach across multi-quadrant surgery
Iteration improved performance, not architecture
New entrants replicate the same architecture
Current Multi-Port System
This is not a market limitation,
it is a structural design constraint inherent to current robotic systems.
External arms create collisions and limit access
A New Architecture Designed for Full Abdominal Access
Enables procedures current systems cannot reach
Internalized single-port eliminates collisions
→ Enables true abdominal access
Human-like articulation enables full dexterity
→ Enables complex procedures minimally invasively
Purpose-built for the full abdomen
A fundamentally different architecture
→ Not an incremental improvement.
We extend robotics beyond the limits of current systems.
Internalized architecture enables full abdominal access without external constraints
A New Category in Robotic Surgery
Not an incremental improvement, a structurally different platform
Different architecture
Different market
Different economics
A new architecture unlocks a new market.

Starting with Ventral Hernia Repair
A high-volume procedure where access limitations drive open surgery
Initial adoption is driven by open conversion, not displacement of existing robotic systems
Reach where others cannot
Full abdominal wall access → enables minimally invasive treatment of cases that are currently performed open.
Large, Constrained Market
>60% of ventral hernia repairs remain open, driven by access limitations.1
High-Impact First Indication
High-volume procedure → strong utilization and repeatable, high-margin consumable revenue.
A direct application of our architecture in a high-value indication2
"We begin by converting the >60% of ventral hernia cases that remain open."

Why Vicarious Enables Conversion of Open Procedures
Designed for full abdominal access and visualization
Limited Access (Laparoscopy)
This is what enables conversion of open procedures to minimally invasive robotic surgery.
Constrained Access (Multi-port Robotics)
Full Access (Vicarious Surgical)
✔ Miniaturized shoulders, elbows and wrists, as if a full arm was operating inside the abdomen
✔ Fully articulating robotic camera enables full abdominal visualization
Simplified Workflow Drives Utilization and Recurring Revenue.
Higher throughput → more procedures per system → increased recurring revenue per installed system
Current Multi-Port Systems
Multi-Port Systems Limit Throughput:
Vicarious Single-Port System
Single-Port System Enables Efficient Turnover:
Faster setup and turnover drive higher system utilization.
Integrated Architecture Lowers Cost and Expands Adoption
Patient Cart
compact footprint, easy integration
Surgeon Console
with integrated display, no vision cart required
Replicating the access of open surgery through a minimally invasive approach
This is what enables conversion of procedures that remain open today.
Decoupled actuators enable additional intra-abdominal joints with true intra-abdominal dexterity and reach.
360° camera articulation with 120° field of view provides full operative field visualization & self cleaning.
Instrument arms generate
high forces needed across soft-tissue indications.
VS Camera: 120° FOV
Integrated Visualization Enables True Abdominal Access
Unprecedented Range of Motion
9.7 mm

Miniaturization
Faster workflow, reduced complexity
Full abdominal access
Enables minimally invasive treatment of open procedures
Stable visualization
Improves precision and consistency
Surgeon Validation
"Often with existing technologies, you fix the trajectory of your arms and your instruments and you're stuck there. If you have to move too far out of that region, the arms start banging into each other; your mobility gets limited. The ability to have a grouped camera and two arms that can move around anywhere in the belly through one incision, one fulcrum, is exciting."
Richard Hoehn, MD | Surgical Oncologist | University Hospitals (Cleveland, OH)
Faster setup, more consistent workflows, and reduced surgeon fatigue
Full-Stack IP Protection Across Core System Architecture
IP spans the full system, not isolated components
Initial Target Procedures: >1M Open Surgeries Annually in the U.S.
Across global markets, the opportunity expands significantly
Initial Target Procedures (~2M annually)1:
Ventral hernia: ~350-500K (60-70% open)
Inguinal hernia: ~700-800K+ (60-80% open)
Recurring, procedure-driven revenue model

Colorectal: ~300K+ (30-40% open)
Conversion Opportunity
~45-55% still open
~0.9M - 1.2M procedures annually

Same-Architecture Competition Compresses Price, Not Market Expansion
New entrants compete for the same procedures, not expand the market
Competing for the same procedures using similar architectures
New entrants are reinforcing this dynamic, not expanding the market
Pricing pressure already visible in competitive regions (e.g., China)
Likely to emerge in the U.S. as new systems enter
Incremental innovation drives competition, not market expansion
We expand the market, not compete for share.
Competing systems fight for share; Vicarious expands the market and creates new procedure volume
