1. Introduction to Medical Technology
1.1 Medical Technology (MedTech)
Definition: The design, development, and use of devices, software, systems, or processes that diagnose, treat, or improve human health. MedTech solutions range from simple bandages to complex surgical robots and AI-driven diagnostics.
Context: MedTech enables earlier diagnoses, safer surgeries, advanced rehabilitation, and more personalised care, significantly shaping modern healthcare delivery.
1.2 Medical Device
Definition: An instrument, apparatus, or machine used for medical purposes—diagnosing, preventing, monitoring, or treating disease—distinct from drugs, as it primarily achieves its effects by physical rather than biochemical means.
Context: Medical devices can be as simple as a syringe or as complex as a multi-axis surgical robot. They usually fall under rigorous regulations (e.g., FDA, MDR in the EU).
2. Core Concepts & Classifications
2.1 Device Classification
Definition: A risk-based categorisation of medical devices (Class I, IIa, IIb, III in EU, or Class I, II, III in FDA), determining the regulatory oversight needed.
Context: Higher classes indicate higher risk to patients/users, requiring more testing, clinical evidence, and post-market surveillance.
2.2 CE Mark / UKCA Mark
Definition: Conformity marks indicating a medical device meets the EU’s (CE mark) or UK’s (UKCA mark) safety and performance standards.
Context: Post-Brexit, UKCA certification applies for devices marketed in Great Britain. CE marking remains relevant in Northern Ireland and the EU.
2.3 Reimbursement
Definition: The process by which healthcare providers or patients are compensated for medical device usage through insurance, national health services, or payers.

Context: Cybersecurity is increasingly critical as more devices integrate IoT or cloud connectivity. Regulators often require vulnerability disclosures and secure development practices.
4.4 User Interface (UI) / Human-Machine Interface (HMI)
Definition: The visual and interactive layer enabling clinicians to operate a medical device. Must be intuitive, consistent with clinical workflows, and designed to mitigate errors.
Context: UI in medtech often includes touchscreens, foot pedals, or voice commands. Testing user interactions is key to safety and adoption.
5. Clinical & Regulatory Pathways
5.1 Clinical Trials
Definition: Formal studies evaluating a device’s safety, efficacy, and performance with human participants. Data from trials supports regulatory approval and market access.
Context: For complex or high-risk devices, multi-phase trials or multi-centre studies are crucial. Ethical committee approvals and informed consent are mandatory.
5.2 Regulatory Submission
Definition: Preparing documentation (e.g. 510(k), PMA in the US or EU technical file) demonstrating compliance with safety and performance standards.
Context: Submissions typically include lab test data, design controls, clinical evidence, and risk management documentation. Approval opens the device to specific markets.
5.3 Post-Market Surveillance
Definition: Ongoing monitoring of devices after launch, gathering real-world performance data, managing recalls or safety notices if issues arise.
Context: Surveillance ensures continuous improvement, detecting rare adverse events or new usage contexts. Regulators like MHRA or FDA may require periodic reports.
