Core offering

Gemini Untwined is a UK-registered charity that provides life-saving surgical separation of craniopagus twins (conjoined twins fused at the head with intertwined brains and shared blood vessels) through multi-stage procedures performed at partner hospitals worldwide. The organization coordinates global surgical teams, funds treatment through donations, and applies proprietary AI-driven surgical planning, mixed reality and virtual reality simulation tools to plan and execute these rare procedures at no cost to families.

Product overview

Gemini Untwined is a charitable organization (not a commercial product company) providing specialized medical services for craniopagus twin separations. The organization operates as a coordination hub bringing together global medical teams, and utilizes advanced technology platforms including XRlabs' AI-powered Surgical Intelligence system for implant design, the simXAR mixed reality platform for anatomical visualization, and VR simulation tools for pre-operative rehearsal. These technologies are employed as operational tools in delivering surgical care rather than being sold as standalone commercial products.

Expansion highlights4 records

Emerging players

• FundamentalVR: VR surgical simulation platform with haptic feedback used for surgeon training and pre-operative rehearsal. Comparable to Gemini Untwined's VR rehearsal workflow for complex procedures.
• Surgical Theater: Provider of VR-based surgical planning and rehearsal platforms used in complex neurosurgery. Directly comparable to Gemini Untwined's VR pre-operative planning technology stack, but commercialized for broader hospital customers.

Broad incumbents

• Children's Hospital of Philadelphia: Leading US pediatric hospital with a history of complex conjoined twin separations and pediatric neurosurgery. Comparable in clinical scope but operates as a general hospital, not a dedicated craniopagus program.
• Brainlab: Established provider of surgical planning software, 3D imaging, and navigation used in neurosurgery and craniomaxillofacial procedures. Comparable in the underlying surgical-planning and 3D modeling technology layer.
• Boston Children's Hospital — Conjoined Twin Program: Major US pediatric hospital with one of the world's most active conjoined twin separation programs. Overlaps with Gemini Untwined in clinical capability for conjoined twin separation, though it is a broad hospital rather than a dedicated charity.

Direct peers

• Operation Smile: Non-profit providing free cleft lip and palate surgeries to children in low- and middle-income countries via volunteer medical teams and donations. Closely analogous charity operating model focused on complex pediatric craniofacial conditions.
• CURE International: Non-profit organization providing free surgical care to children in underserved regions, with a similar donation-funded model for complex pediatric procedures. Comparable operating model: charity mobilizing surgical teams and donor funding to deliver specialized procedures children could not otherwise access.
• Smile Train: Non-profit providing free cleft palate and craniofacial surgeries globally through a partner-hospital network and donor funding. Directly analogous in mission (free complex pediatric craniofacial surgery), funding model (donations), and delivery model (partner-hospital enablement).
