Started Stockcross Consulting Ltd in 2014 to provide expertise to organisations primarily in the areas of medical device design, design control, and quality systems. Examples of projects undertaken so far are:•A project, working with a UK-based manufacturer of medical devices to improve their design control and risk management procedures. Initially, the company’s systems for design control and risk management were reviewed against the requirements of international standards and regulations. Once the review was completed, a revised design control procedure was written, compliant with the requirements of ISO 13485, EU Medical Devices Directive (93/42/EEC) and US FDA quality system regulation, 21 CFR 820.•Working with a UK-based manufacturer of specialist textile solutions for the medical devices industry, the aim of the project was to work with their US partner to improve the product release and testing criteria for textile products for the US market. Test methods were developed for batch release to ensure that products for export to the US continue to meet the product requirements. •With the same company, help was also provided to prepare for their first FDA audit, including participation in the entire 4 day inspection. No non-conformities were identified by the investigator•Working with an EU manufacturer of tissue adhesive. Initially, risk management procedures and activities were reviewed. New procedures were written suited to the needs of the organisation. Failure mode and effect analyses (FMEAs) were then facilitated for the organisation after implementation of these procedures.•A contract to provide assistance to the Design Assurance department of a multinational contract manufacturing organisation. Working on a project for a high volume injection-moulded drug delivery product assisting with design and process FMEAs, design verification reviews, process validation (including Validation Master Plan – VMP) and quality planning.

Oxford Endovascular Limited is a spin out from The University of Oxford. The Company is developing metallic mesh tube devices invented by engineers and clinicians at the university to treat patients suffering from brain aneurysms.
