Overview of Resorbable Vascular Scaffolds

Resorbable vascular scaffolds (RVS) are innovative medical devices designed to provide temporary support to blood vessels after interventions such as coronary artery bypass grafting (CABG) or percutaneous coronary interventions (PCI). Unlike traditional metallic stents, resorbable vascular scaffolds are made from biocompatible materials that gradually dissolve in the body over time. This dissolution process allows for the restoration of the vessel’s natural architecture and function, reducing the risk of long-term complications such as restenosis (re-narrowing of the artery) and thrombosis (blood clots).

The growing demand for less invasive, long-term effective treatments and biocompatible materials has significantly driven the adoption of resorbable vascular scaffolds. These devices offer the benefits of traditional stents in terms of mechanical support while avoiding the long-term presence of a foreign object in the artery.

Market Insights and Trends

The resorbable vascular scaffolds (RVS) market is witnessing rapid growth due to advancements in material science, increasing incidences of cardiovascular diseases, and a preference for bioresorbable over metallic stents. With growing awareness among healthcare professionals and patients about the benefits of RVS, the market is expected to expand significantly by 2030.

Key market drivers include:

Increasing Incidence of Cardiovascular Diseases:

Cardiovascular diseases (CVDs) are the leading cause of death globally. The rising prevalence of coronary artery diseases (CAD) and the aging population are major contributors to the growing demand for effective vascular interventions.

Preference for Bioabsorbable Solutions:

Resorbable scaffolds offer a temporary solution that dissolves after completing its function, which reduces the risk of complications associated with permanent stents. The potential for restoring normal vascular function after the scaffold dissolves is a significant factor driving interest.

Technological Advancements:

Significant progress in the development of materials such as polylactic acid (PLA), polyglycolic acid (PGA), and magnesium alloys has improved the mechanical properties and resorption rates of vascular scaffolds. Innovations in scaffold design, such as bioresorbable polymers with enhanced strength and flexibility, have also contributed to market growth.

Favorable Regulatory Environment:

As healthcare systems continue to approve bioresorbable solutions, regulatory bodies such as the FDA and EMA are increasingly providing clear guidelines for the development and approval of resorbable vascular scaffolds, making it easier for companies to bring these products to market.

Growing Demand for Less-invasive Procedures:

The increasing preference for minimally invasive procedures like PCI, which allows doctors to treat blocked arteries through small incisions, is driving demand for advanced stent technologies. RVS provides a better long-term outcome compared to conventional metallic stents.

Current Treatment Landscape

Currently, vascular interventions primarily use metallic stents, which have limitations such as the risk of restenosis and the long-term presence of a foreign object in the body. RVS offers advantages by addressing these challenges, as they gradually dissolve and do not leave a permanent foreign object in the artery.

Resorbable Vascular Scaffold Materials:

Polylactic acid (PLA) and poly-lactic-co-glycolic acid (PLGA) are commonly used materials for manufacturing RVS due to their favorable mechanical properties and biocompatibility.
Magnesium-based scaffolds: Magnesium alloys are another emerging material used in resorbable scaffolds, offering the benefits of resorbability and a high strength-to-weight ratio.

Key Market Players and Products:

Abbott Laboratories: Abbott’s Absorb bioresorbable coronary scaffold was one of the most well-known RVS products, though it was eventually withdrawn from the market in 2017 due to performance issues in clinical trials. However, Abbott continues to develop alternative resorbable products.
Biotronik: Biotronik’s Magmaris is another resorbable scaffold product, made from magnesium-based alloys, providing mechanical strength while being bioresorbable over time.
Boston Scientific: Boston Scientific has developed Eluvia, a drug-eluting stent system, which is not bioresorbable but represents the competition faced by resorbable vascular scaffolds in the coronary artery intervention space.

Competitive Landscape

The RVS market is highly competitive, with several key players working on developing and commercializing bioresorbable scaffold technologies. These include multinational companies, startups, and academic institutions focusing on innovations in material science, scaffold design, and clinical validation. The competitive landscape can be segmented as follows:

Market Leaders:

Abbott Laboratories: Despite the challenges faced by Abbott’s Absorb stent, it remains a leading name in vascular interventions. The company is focusing on advancing resorbable technology and other innovative stent solutions.
Biotronik: Biotronik’s Magmaris and Absorb competitors focus on the development of high-strength, biocompatible materials, and magnesium-based products that dissolve over time.

Emerging Players:

Elixir Medical: The company has developed bioresorbable scaffolds and focuses on drug-eluting scaffolds, which combine the benefits of drug therapy with the resorbable structure.
Reva Medical: Reva Medical is working on biodegradable scaffolds using proprietary materials, aiming to improve outcomes in coronary interventions.

Research Institutions: Many academic and research institutions are also focusing on developing new biodegradable materials and scaffold structures. Collaborative efforts between these institutions and companies are expected to bring innovations to the market.

Epidemiology

The market for resorbable vascular scaffolds is influenced by the increasing prevalence of cardiovascular diseases, particularly coronary artery diseases (CAD). As populations in both developed and developing countries age, the incidence of cardiovascular disorders is rising.

Prevalence of CAD: Coronary artery disease is the most common form of heart disease worldwide. The global prevalence of CAD is expected to increase significantly by 2030, directly impacting the demand for vascular interventions.
Age Group: Older adults, particularly those above 65, are at higher risk of developing CAD. As the aging population grows, the need for coronary interventions using technologies like RVS will rise.

Market Forecast – 2030

The resorbable vascular scaffold market is expected to experience significant growth through 2030, driven by factors such as increasing cardiovascular disease prevalence, technological advancements in scaffold materials, and rising demand for biocompatible and bioresorbable stent solutions.

Market Growth Drivers:

Aging Global Population: As the global population ages, the number of individuals affected by coronary artery disease will rise, creating a higher demand for RVS.
Technological Innovation: Ongoing research into new materials such as magnesium alloys and biodegradable polymers will improve the performance and reliability of RVS, leading to increased adoption.
Preference for Non-Permanent Solutions: The market is expected to see growth as more patients and healthcare providers opt for resorbable solutions due to the reduced risk of complications and the ability to restore natural vessel function.

Challenges:

Regulatory Hurdles: While RVS has clear advantages, regulatory bodies may require more clinical data on long-term safety and effectiveness before full-scale adoption.
Competition from Drug-Eluting Stents: Drug-eluting stents (DES) continue to be widely used due to their proven efficacy in preventing restenosis, which poses competition for RVS.

The resorbable vascular scaffold market is projected to grow at a CAGR of 9-10% from 2023 to 2030, with key innovations and regulatory approvals driving its expansion.
