The need for modern medicine to extend quality life of a worldwide aging population requires new technologies and models for testing new therapies or devices. Besides performing high quality research the CMCiB develops innovative tools and provides expertise to help researchers and industry users transfer their innovations to the patient or the market.

CMCiB as a Reference Centre in the Validation of Medical Devices
As a reference centre in the validation of medical devices, in addition to the GLP validation of iVascular and Rob Surgical products and new medical device candidates in the portfolio, CMCiB has positioned itself over the years as a reference centre in the territory for the validation of new and complex technologies.
Recently, an important early-phase multicentric clinical study (first-in-human, FIH) for patients with coronary microvascular dysfunction or microvascular angina has been initiated, using an innovative therapy developed by VahatiCor Inc, an international client of the centre specialised in developing medical devices addressing unmet medical needs for cardiac patients. CMCiB has carried out preclinical validation functional studies with the A-FLUX Reducer performed in their state-of-the-art surgical facilities, as well as specialised training for reference clinicians, enabling them to use the new product in people in the planned trials, reaffirming CMCiB's position as a reference centre in the validation of medical devices within various therapeutic areas.
The A-FLUX Reducer, implanted in the coronary sinus -the largest vein of the heart-, has been designed to improve blood flow in ischemic areas of the heart, with the aim of alleviating symptoms and enhancing the quality of life of patients.
This success story demonstrates the capability of new technologies to meet unmet medical needs, by "providing predictable and low-risk treatments for a growing population of patients with angina symptoms who do not achieve satisfactory results with conventional medications or lifestyle changes", as noted by VahatiCor.
NIMBLE Diagnostics: Groundbreaking Microwave-based Medical Device for non-invasive stent monitoring
NIMBLE Diagnostics is pioneering a groundbreaking microwave-based medical device for the non-invasive monitoring of patients with implanted stents. Stents are commonly used to re-open blocked arteries (e.g. Heart attacks) and prevent vascular issues, but they often fail without noticeable symptoms until it's too late, leading to serious complications. Current diagnosis relies on invasive procedures. NIMBLE's system can accurately detect stent issues (blockages, fractures, etc) in seconds during routine clinical visits, enabling early intervention and personalized care. Their technology has shown excellent results in pre-clinical testing, with a pilot study on 120 patients ongoing, aiming to reduce heart attacks, hospitalizations, and premature deaths.
According to NIMBLE, the experience and support from CMCiB was very helpful in the pre-clinical validation of their technology and has allowed them to move into clinical trials.
Establishment of a new reproducible and minimally invasive stroke model through an endovascular approach
Researchers of the Cellular and Molecular Neurobiology (CMN) Research Group at the Germans Trias i Pujol Institute (IGTP) have developed and established a novel, reproducible and minimally invasive stroke model in pigs through an endovascular approach. The work has been conducted at the Centre for Comparative Medicine and Bioimage (CMCiB), a centre devoted to translational medicine at the very core of the Can Ruti Campus in Badalona together with the IGTP and the Germans Trias i Pujol University Hospital.
This recent advance fulfils the requirements needed to promote an efficient translation of innovations and new treatments from the bench to the bedside in this field. The study is published in the April 2023 issue of the Journal of Clinical Investigation Insight as a remarkable Technical Advance that mimics the occlusion at the same cerebral artery site reported in the most widely used experimental stroke model in mice and rats, but using pigs as the experimental subject for its brain is far more similar to that of humans than rodent's. The need for animal models of stroke to search for and to find new treatments in species with more human-like brain characteristics as compared to rodents, but avoiding the use of non-human primates to fulfil the EU regulations and to fit ethical concerns, is a long-pursued demand of stroke.
In this regard, this novel stroke model in pigs will allow to better model and keep on studying the mechanisms operating in stroke that are also present in stroke patients, and to find stroke therapies useful to alleviate patients. The new technique described produces an effective occlusion of the cerebral arteries of interest, induces early focal brain damage at the desired cerebral regions 90 min post-occlusion that later evolves to a large cerebral infarction, and produces neither mortality during the intervention nor surgical-derived discomfort. This novel ischemic stroke model in pigs shows translational features strikingly common to human stroke, including damage to the white matter axonal tracts that transmit information interconnecting specific functional brain areas. In this model, the researchers used longitudinal multimodal cerebral MR imaging similar to the one currently used in the clinical set up to assess the evolution of brain damage and cerebral blood supply.
"The reproducibility of the damage in specific brain areas in the model is important to any study that aims to determine the true neuroprotective effect of new molecules to be tested in brains similar to those of humans", says Dr. Teresa Gasull, who has led the study. In words of Dr. Carlos Castaño and Marc Melià-Sorolla, co-first authors of the study, "We expect this new model will foster the development of new therapeutic compounds and devices to treat patients in the years to come".
