Heart Valve Stent Solutions for Transcatheter Interventions

CATALOG's Heart Valve Stent is a critical, high-performance component for transcatheter valve replacement and repair systems. It is specifically engineered for the treatment of mitral regurgitation (MR) and tricuspid regurgitation (TR), supporting the next generation of minimally invasive, transcatheter structural heart therapies.

Engineered for Performance and Safety:

The stent is manufactured from surgical implant-grade cobalt-chromium alloy wire, sourced to meet stringent ASTM F1058 standards. This ensures exceptional biocompatibility, radial strength, fatigue resistance, and MRI compatibility, which are paramount for long-term implantation in the dynamic cardiac environment.

A Trusted Partner in Innovation:

We have established in-depth development partnerships with several leading medical device companies. CATALOG supports these collaborations through our integrated capabilities in:

Our mission is to provide the high-reliability, precision components that form the foundation of safe and effective interventional cardiac treatments.

Pain Point Analysis & Solutions for Heart Valve Stents

Challenge	CATALOG’s Response	Outcome
1. Poor Hemodynamics & Restricted Flow Conventional stent structures create uneven pressure distribution and flow turbulence, limiting the effective orifice area (EOA) and resulting in suboptimal hemodynamic performance (e.g., high transvalvular gradient).	Optimized Flow Design • Independent Tricuspid Valve Frame: Features a diaphragm-free right coronary post design to maximize geometric orifice area. • Pressure Distribution Engineering: Optimized cell geometry to reduce flow resistance and expand the functional valve opening area.	• Enhanced Hemodynamic Performance: Achieves superior blood flow characteristics with lower gradients, ensuring smooth, efficient circulation and reducing cardiac workload.
2. Difficult Implantation in Complex Anatomy Challenging anatomies with irregular, elliptical, or heavily calcified annuli make secure seating and suturing of traditional rigid stents difficult, increasing procedural risk and potential for paravalvular leak (PVL).	Anatomically Adaptive Seating • Contoured Waveform Seat: Mimics the natural shape of the aortic root for improved anatomical conformity. • Coronary Top Clearance: Designed to accommodate high or irregular coronary ostia and conform to calcified annuli, simplifying suturing.	• Improved Fit & Seal: Enhances implant conformity to native anatomy, simplifying the suturing process and reducing the risk of paravalvular leak (PVL).
3. Premature Valve Wear & Limited Durability Leaflet-frame contact, abrasion, and stress concentration points accelerate structural valve deterioration (SVD), leading to reduced long-term durability and potential for re-intervention.	Engineered for Long-Term Integrity • Integrated Suturing Points: Eliminates direct leaflet-to-frame contact and friction. • Shock-absorbing Elastic Frame: Absorbs cyclic hemodynamic forces for uniform stress distribution. • Premium Materials & Validation: Uses ASTM F1058 cobalt-chromium alloy wire and validates with extensive fatigue testing (e.g., 400 million cycles).	• Extended Product Lifespan: Significantly reduces wear mechanisms, enhancing long-term durability and reliability to meet the demanding lifetime requirements of heart valve implants.
4. Limited Adaptability to Patient-Specific Needs The spectrum of patient annular sizes and pathological conditions (e.g., bicuspid aortic valve) exceeds the adaptability of off-the-shelf, standardized stent platforms.	Fully Customizable Platform • Tailored Dimensions: Supports complete customization of outer/inner diameter, wire diameter, and height. • Adaptable Secondary Processes: Offers adjustable welding, polishing, and cleaning protocols to meet specific design and finish requirements.	• Precision Patient Matching: Enables stents to be accurately tailored to individual anatomical and clinical needs, expanding treatable patient populations and improving procedural outcomes.

CATALOG Spring Solutions

Comprehensive Customization & Material Expertise

We provide a fully customizable platform supporting a range of high-performance cobalt-chromium alloys, including MP35N, L605, and Elgiloy. Critical dimensions—outer/inner diameter, wire diameter, and stent height—are tailored to specific valve designs. We also adapt secondary processes like welding, polishing, and cleaning to meet exacting personalized requirements.

Anatomically & Hemodynamically Optimized Design

Maximized Flow: Features an independent tricuspid valve frame with a diaphragm-free right coronary post, optimizing pressure distribution and maximizing the effective orifice area (EOA) for superior hemodynamics.

Secure Anatomical Fit: The contoured, waveform aortic seat mimics the native aortic root shape, accommodating high coronary ostia and conforming to irregular or calcified annuli, simplifying implantation and improving seal.

Implant-Grade Quality & Traceability

Our stents are manufactured from certified, surgical implant-grade cobalt-chromium alloy wire, validated through extensive reliability testing (400 million fatigue cycles). A controlled, fully traceable manufacturing process—from coiling and welding to polishing and cleaning—ensures batch-to-batch consistency, material integrity, and long-term performance on par with leading global standards.

Engineered for Long-Term Durability

Dynamic Compliance: The elastically designed valve frame accommodates cardiac cycle compliance, absorbing hemodynamic shock loads.

Wear Elimination: Integrated leaflet attachment points eliminate direct abrasion between the leaflet and frame.

Stress Management: This combined approach ensures uniform stress distribution, prevents load concentration, and significantly extends the service life of the valve leaflets
