Biomedical Textiles for Cardiovascular Applications
Today’s biomedical textile structures can be engineered to support and promote the healing and even the regeneration of damaged cardiovascular tissue, with complex and fully customizable geometries.
Cardiovascular devices are becoming smaller, less invasive, and more complex. To meet these demands, biomedical textiles must deliver exceptional strength, flexibility, and precision in increasingly lower-profile designs.
At Cortland Biomedical, we engineer braided, woven, and knitted textile structures that enable next-generation cardiovascular technologies—from electrophysiology and cardiac diagnostic catheters to structural heart therapies and endovascular interventions. We have extensive experience using medical-grade fibers of various sizes and properties such as ultrahigh molecular weight polyethylene (UHMWPE) and polyester. By tailoring fiber selection and construction methods, our textiles can support minimally invasive delivery while maintaining the durability and performance required in demanding cardiovascular environments. Final textile structures can be customized to provide:
- Controlled density and porosity
- High tensile strength and dimensional stability
- Flexibility and shape transformation capabilities
- Radial reinforcement and expansion
- Biocompatibility
- Architecture for tissue integration
- Lower-profile, less invasive device designs
Applications
Electrophysiology
As electrophysiology (EP) procedures become increasingly complex and devices continue to shrink, manufacturers need components that deliver precision, flexibility, and durability in increasingly lower-profile designs. For cardiac diagnostic applications, including intracardiac echocardiography (ICE) catheters used during electrophysiology procedures to guide mapping and ablation,, next-generation EP technologies depend on advanced textile solutions that enable precise navigation,optimal mechanical performance, and stability, while aiding other components in the effective transfer of torque.. At Cortland Biomedical, we engineer braided cable solutions that help OEMs balance critical design requirements—including flexibility, strength and durability—to support the development of high-performance electrophysiology devices, including mapping catheters, ablation systems, ICE and ultrasound catheters, and steerable catheter platforms.

Structural Heart
As valve therapies evolve, biomedical textiles are doing more than holding components together – they’re enabling the next generation of minimally invasive treatment. From performance-critical skirts to precision-engineered braids, Cortland Biomedical’s solutions are woven into the future of structural heart care.
Cortland Biomedical supports next-generation structural heart device development with custom engineered textile solutions designed to enhance durability, deliverability, and long-term device performance across complex cardiac interventions. Our braided, knitted, and woven material platforms can support a wide range of implantable and transcatheter technologies, including transcatheter valve repair and replacement systems (TAVR, TMVR, and TTVR), where precise structural support is required to facilitate controlled deployment, reliable anchoring, and sustained performance in minimally invasive procedures.
In Transcatheter Aortic Valve Replacement (TAVR), textiles play a crucial role in the design and functionality of the replacement valve. For example, polyester or ePTFE textiles are used in valve skirts to prevent paravalvular leakage and support endothelialization. Textiles also reinforce the leaflets and anchoring systems, ensuring secure placement and long-term durability in the aorta’s high-pressure environment. In the delivery system, braided textiles guide the catheter and control valve release. Cortland Biomedical’s braids offer unmatched strength and flexibility, which is critical for navigating tight, difficult pathways with precision.
The mitral valve’s irregular shape and high-pressure environment require highly adaptive textile constructions. Cortland Biomedical’s precision textiles conform to the mitral annulus, distribute mechanical load, and support leaflet function without compromising durability. During deployment, our braided structures can enable smooth, controlled navigation through the vasculature and across the left atrium, ensuring that the larger TMVR device reaches its target intact and aligns accurately within the heart.
TTVR procedures face complex anatomy and variable pressure conditions. Cortland Biomedical’s textiles deliver flexibility and conformity to seal against the tricuspid annulus, minimize regurgitation, and secure the device in a shifting environment. For the delivery system, our braids excel in maneuverability and friction reduction, which is especially important when advancing the valve through the vena cava and positioning it precisely in the heart.
In other structural heart applications, our textiles can be incorporated into left atrial appendage closure devices to support secure occlusion and reduce thromboembolic risk, as well as septal closure systems where controlled porosity, radial strength, and fatigue resistance are critical to long-term defect sealing. Our braided textile technologies can also support intracardiac echocardiography (ICE) catheters, providing the flexibility and catheter performance required for high-quality cardiac diagnostic imaging during structural heart procedures to help guide device deployment and confirm accurate implant placement.
Vascular
Cortland Biomedical can support next-generation vascular device development with advanced textile solutions engineered for strength, flexibility, and long-term durability in demanding vascular environments. In peripheral stent applications—including those used to treat peripheral artery disease (PAD) in the lower extremities and carotid artery disease—engineered fabrics and reinforcements are designed to support vessel patency, enhance radial strength, and maintain conformability through complex and tortuous anatomy while preserving reliable long-term performance.
In endovascular aneurysm repair (EVAR) and thoracic endovascular aortic repair (TEVAR) graft systems, textile coverings and structural reinforcements play a critical role in achieving effective exclusion of aneurysms while maintaining graft integrity and desired blood flow. These materials are designed to support sealing, reduce endoleak risk, and provide durable vessel wall reinforcement across the aortic arch, thoracic aorta, and abdominal aorta where mechanical forces are significant and long-term reliability is essential.
Across both peripheral and aortic applications, Cortland Biomedical textile architectures are engineered to balance strength and flexibility while enabling controlled delivery, secure deployment, and sustained vascular support in minimally invasive procedures.
