Flexible Delivery Sheaths
Clinical Application
Flexible delivery sheaths are used to support controlled advancement of interventional devices through tortuous vascular anatomy while maintaining stable access from the insertion site to the target location.
They are commonly used in structural heart interventions, peripheral vascular procedures, and complex catheter-based therapies where navigation, pushability, and positional stability are critical.
Flexible delivery sheaths support:
- Smooth advancement through curved or angled vessels
- Reduced vessel trauma during device delivery
- Stable conduit for large-profile devices
- Controlled access during device exchange and retrieval
Design and Performance
ALSPL flexible delivery sheaths are designed to balance flexibility, support, and lumen stability.
Key characteristics include:
- Multi-layer shaft construction to optimise pushability and flexibility
- Controlled inner lumen geometry for device compatibility
- Smooth internal surface to reduce friction during advancement
- Kink resistance to support navigation through tortuous anatomy
- Secure proximal hub interface for stable manipulation
Flexibility is graduated along the shaft to provide proximal support and distal compliance where required.
Construction Options
Flexible delivery sheaths may be configured with:
- Variable flexibility profiles
- Reinforced shaft structures
- Defined inner diameter platforms
- Compatible dilator or obturator systems
- Interface options suited to structural and peripheral workflows
Length and diameter selection depends on anatomical pathway and procedural requirements.
Standard Configurations
Standard delivery sheath platforms are available across commonly used French sizes and length ranges.
Dimensional specifications and detailed configurations are provided in the product brochure.
Customisation
Custom flexible delivery sheath programs may include:
- Alternative shaft lengths
- Modified flexibility gradients
- Custom inner diameter platforms
- Reinforcement adjustments for enhanced support
- Modified hub interfaces
- Integration into structural heart or peripheral delivery systems
- OEM and private label manufacturing
Custom designs are evaluated to ensure device compatibility and predictable performance.
