A surgeon watches a live case demo at a cardiology congress in Paris. Eighteen months later, that same surgeon has run the device on 40 patients, trained two colleagues, and written it into the hospital's default treatment protocol.

Unlike a SaaS free trial, it can take two to four years, involves committees rather than individuals, and ends not with a purchase but with something more durable: becoming the standard of care.
In consumer or B2B software, the funnelfunnelThe customer journey from awareness to purchase, typically Awareness, Interest, Consideration, Decision, Action, with prospects narrowing at each stage.View full definition → is roughly: click, sign up, activate, pay, renew. In biotech and medtech, the "buyer" is a fragmented committee: the physician who wants the device, the hospital procurement office that controls the budget, and the payer (insurer or national health system) that decides reimbursement.
A key term first: standard of care means the treatment that clinical guidelines and peers consider the default, correct choice for a given condition. Reaching it is the real goal, because once a device or therapy is embedded in a hospital protocol and a specialty society guideline, switching costs become enormous. That is your retention moatmoatA lasting edge over competitors: a resource, capability or position they cannot easily replicate, letting a firm earn above-average returns over time.View full definition →.

Entry point is usually a medical congress (a large specialty conference like ESC for cardiology or ASCO for oncology) plus KOL engagement. A KOL, or Key Opinion Leader, is an influential physician whose adoption signals credibility to peers.
Metric: qualified congress leads, meaning clinicians who visited the booth, attended a symposium, or requested follow up, filtered to those in your target specialty and institution type.
The clinician requests an evaluation: a demo, a data pack, or entry into an evaluation trial. This is the first true intent signal.
A supervised trial of the product, often on a handful of cases, sometimes under a formal clinical evaluation framework. In the EU, ongoing clinical evidence is required under the Medical Device Regulation (MDR, Regulation 2017/745), which fully applies as of 2024 to 2025 transitions. In the US, market entry runs through the FDA via 510(k) clearance (showing equivalence to an existing device) or PMA (Premarket Approval, the stricter path for high risk devices).
The clinician performs the first real, paid procedure. This is your activation event, the medtech equivalent of a first purchase.
The clinician uses it routinely, and adoption spreads to colleagues in the same department.
The device or therapy is written into the hospital's clinical protocol and, ideally, referenced in specialty society guidelines. This is durable retention.
Let's model a medtech field team launching a surgical device in a mid-size European market. Numbers are illustrative planning assumptions.
| Gate | Volume | Conversion to next |
|------|--------|--------------------|
| Qualified congress leads | 1,000 | 25% |
| Evaluation requests | 250 | 40% |
| Evaluation trials run | 100 | 60% |
| First procedures | 60 | 70% |
| Repeat / routine users | 42 | 30% |
| Protocol embedded accounts | ~13 |, |
End to end, 1,000 leads produced roughly 13 embedded accounts, a 1.3% congress-lead-to-standard-of-care rate. That sounds brutal, but each embedded account may represent decades of recurring procedures.
The single most useful number to track per gate is stage conversion rate:
Stage conversion = (entities exiting this stage into the next) / (entities entering this stage)
Find your worst gate. Above, evaluation trial to first procedure (60%) and repeat to embedded (30%) are the leaks. A 10 point improvement at the repeat-to-embedded gate here adds roughly 4 embedded accounts, a 30% lift in the outcome that actually compounds.

For grounding your assumptions in real device economics and evidence expectations, the FDA's plain-language overview of device pathways is a solid free start: FDA Device Approvals and Clearances.

Two metrics deserve dedicated tracking because they predict Gate 6.
Procedure velocity: procedures per active account per quarter. A flat or declining velocity after first use signals the account will never embed. Rising velocity is your leading indicator of protocol adoption.
Depth of adoption: number of trained clinicians per account. One champion is fragile; if they leave, adoption collapses. Three or more trained users signals institutional stickiness.
For retention, the medtech equivalent of churn is de-adoption: an account that stops ordering or reverts to a competitor or the prior standard. Track:
De-adoption rate = accounts lost in period / active accounts at start of period
Estimated annual de-adoption for well-embedded devices tends to be low, often in the single digit percentages, because protocol change requires committee action.
