COIL TYPES
HELICAL/SOLENOIDAL COILS
Traditional winding designs used in guidewire tips, reinforcement structures, and delivery systems.
Multi-pitch coils
Feature variable pitch along the length to fine-tune flexibility, stiffness, and compression behavior.
tapered coils
Designed with changing diameters or pitch to achieve graded mechanical properties and improved device performance.
flat/ribbon coils
Utilize flattened wire profiles wound into coil geometries for specialized flexibility or compact integration.
complex/custom 3d-shape coils
Engineered with non-cylindrical geometries or integrated into catheter shafts and hybrid subassemblies.
single-layer coils
Provide consistent flexibility and support, ideal for standard catheter and guidewire constructions.
multi-layer coils
Offer enhanced torque response, kink resistance, and mechanical stability.
CUSTOM coils
Precision-engineered to meet specific dimensional, functional, or integration requirements.
materials and finishes
Materials
Stainless steel (302/304V), MP35N, nitinol, platinum–iridium, tungsten, and other specialty alloys.
Surface & Coating Options
Electropolishing, passivation, Parylene, PTFE, polyimide insulation, hydrophilic coatings, polymer jackets, and radiopaque markers.
Precision Tolerances
Coils and wires can be manufactured to diameters as small as 0.001″, with micrometer-level tolerances for both diameter and length.
Applications
Our wires and coils find use in a variety of medical devices and subsystems:
- Cardiovascular (guidewires, embolic coils)
- Neurovascular devices
- Catheter-based systems
- Diagnostic and therapeutic devices
- Minimally invasive delivery systems
Because we design with your target anatomy, mechanical requirements, and geometry in mind, the outcome is a coil or wire element integrated seamlessly into your device.
Capabilities
Comprehensive Process Capabilities
Laser cutting, precision coiling, tapering, grinding, forming, welding/bonding, finishing, and inspection — all performed under tight process control.
Cleanroom Assembly
All assembly is conducted in ISO-classified environments, ensuring sterility, traceability, and full regulatory compliance.
Scalable Manufacturing
From rapid prototypes and small-batch builds to high-volume production, our processes scale seamlessly with your program.
Collaborative Design & Integration
Our engineering team partners early in development to refine coil and wire geometries, optimize material selection, and enhance manufacturability.
Quality Systems & Traceability
ISO systems drive every operation, with lot-level tracking, complete documentation, and verification at each stage.
Tailored Customization
Adjustments in pitch, coil length, taper transitions, insulation, and transition regions are readily accommodated to meet exact performance needs.
Your Competitive Advantage
Where larger competitors may emphasize scale or breadth, Salt Medical stands apart through rapid prototyping, tighter collaboration, and hands-on client engagement, all without compromising precision or performance.
