We turn ideas into real products.

ISO 13485 certified engineering company. We help start-ups and SMEs take medical devices, aesthetic equipment and laboratory instrumentation from concept to market — designing products oriented to obtain MDR / FDA clearance.

Who we work with

Three sectors, one same standard

Companies that need a technical partner capable of delivering regulated or technically demanding products — without splitting the project across five suppliers.

ECG-Expert — medical device developed by the CS&E group engineering team

Medical devices

We work with start-ups and SMEs developing regulated devices: patient monitoring, cardiology, imaging, rehabilitation or digital health. We design products oriented to obtain MDR / FDA clearance — without replacing the client's regulatory bodies. We've done it before with our own products (ECG-Expert) and with client products.

Aesthetic medicine device developed by TecnoCSE

Aesthetic medicine

We design the electronics and software of IPL, laser, radiofrequency, HIFU and cryolipolysis equipment. We focus on modern touch interfaces, management apps and cloud integration — real differentiation in the professional channel. These devices fall under MDR Annex XVI, a regulation we've already applied in previous projects.

Lab equipment developed by TecnoCSE

Laboratory equipment

We modernise analytical equipment, IVD instrumentation and research devices: high-precision electronics, embedded firmware, LIMS integration and component obsolescence management. These devices are regulated under IVDR (the sister regulation to MDR) — a certification cycle we've already completed in previous projects.

Scope of our role

How we fit into your team

We're an engineering supplier. The client retains ownership of the product and the role of legal manufacturer. These are the clear limits of our responsibility.

What we do

Activities included in our typical scope

  • Product design and development (HW, FW, SW and mechanics)
  • Modernisation of legacy electronic platforms
  • Technical documentation under ISO 13485 / IEC 62304
  • Support for conformity testing (IEC 60601-1, IEC 61010-1, etc.)
  • Obsolescence management of key components
  • Prototypes, pre-production and serial manufacturing
  • Technical after-sales service and repair

What we DON'T do

Activities that remain the client's responsibility

  • Acting as the legal manufacturer of the product
  • Approving or signing the CE mark on the client's behalf
  • Replacing the Notified Body or the health authority
  • Clinical trials or analytical validation of reagents
  • Production of consumables or chemical reagents
  • Commercial strategy or post-market surveillance of the end product
Why TecnoCSE

Six reasons to entrust us with your development

What sets us apart from a generic consultancy and from a freelancer: a complete team with experience in regulated sectors.

01

Complete technical capability

Hardware, firmware, software and manufacturing under a single interlocutor. No need to coordinate four suppliers to reach the final product.

02

ISO 13485 certified company

We hold a current, audited ISO 13485 certification for quality management systems of medical devices. Our documentation fits the client's without adding regulatory friction.

03

20+ years in regulated products

Designing electronics and firmware for demanding sectors since 2002. We know the real cost of a deviation or a late prototype iteration.

04

Multidisciplinary in-house team

Hardware, firmware, application software, mechanical and industrialisation engineers — all in-house. No critical core depends on a subcontractor.

05

Made in Barcelona

The whole cycle, from idea to the first production batches, runs through our workshop at the Sant Pau Modernist Site. Visits and audits are welcome.

06

Group with its own track record

We're part of the CS&E group, which has brought to market its own products distributed in more than ten countries. We don't theorise medtech: we practise it.

How we work

From idea to product, in four phases

A methodology we've refined over 20 years of projects — adaptable to the stage where the client finds us.

PHASE 01

Definition

We work with the client to set specifications, applicable regulatory requirements, realistic budget and timeline.

PHASE 02

Engineering

Hardware, firmware and software design. We generate the technical documentation (gerbers, BOMs, source code, manuals) following ISO 13485.

PHASE 03

Prototype and validation

Manufacturing of the first prototypes, commissioning, functional verification and support for the clinical or market validation process.

PHASE 04

Production

Serial manufacturing, quality control, traceability and after-sales service. Obsolescence management and life-cycle reviews.

Applicable experience

Regulatory experience that crosses all three sectors

We are an ISO 13485 certified company with real track record across the three regulations that govern our sectors:

  • MDR (EU 2017/745) — We developed our ECG-Expert, Class IIa with Notified Body 0318, and products for clients in the medtech sector.
  • MDR Annex XVI — We've developed aesthetic equipment for clients under this reclassification (laser, IPL, radiofrequency and similar).
  • IVDR (EU 2017/746) — We've developed laboratory instrumentation for clients under the in-vitro diagnostic regulation.

The same methodology applies to products oriented to FDA. Working with a team that has already lived through the full certification cycle with a Notified Body is the best guarantee that your product will reach the market with its technical documentation ready.

Success stories

From concept to market: two real examples

A group device already on the market with MDR clearance and a European project under way with reference partners. We speak with facts, not promises.

CS&E group product · On the market

ECG-Expert

Wireless 12-lead electrocardiograph developed entirely by the group's engineering team: isolated acquisition hardware, embedded firmware, native multi-platform apps and serial manufacturing. Developed in collaboration with Hospital Clínic de Barcelona and commercialised by MedicalCSE.

European stress-ECG analysis platform with AI

The CS&E group — together with two Dutch partners, Cordys Analytics and UMC Utrecht — is developing an AI platform for stress-ECG analysis, aimed at the early detection of cardiovascular diseases that today go unnoticed on a resting ECG.

The CS&E group's contribution to the consortium: design of the multi-lead electronics, integration with our own device (ECG-Expert) and regulatory experience in MDR Class IIa.
