Micropuncture Sets
Clinical Application
Micropuncture sets are used to obtain controlled vascular access using a low-profile needle and guidewire before upsizing to a standard introducer sheath.
They are commonly used in interventional cardiology, peripheral vascular procedures, neurovascular access, and critical care interventions where vessel preservation and controlled entry are important.
Micropuncture technique supports:
- Reduced initial puncture size
- Improved control during guidewire introduction
- Lower risk of vessel trauma
- Safer access in small or fragile vessels
- Paediatric and neonatal access workflows
Design and Performance
ALSPL micropuncture sets are designed as integrated access systems in which each component functions together during initial vessel entry and transition.
Key characteristics include:
- Low-profile introducer needle for precise vessel access
- Flexible guidewire construction to support atraumatic advancement
- Controlled dimensional compatibility between needle, guidewire, and dilator
- Smooth transition to standard introducer systems
- Stable hub interfaces for procedural control
Component interaction is engineered to minimise resistance during guidewire passage and dilator advancement.
Guidewire Construction
The guidewire supplied within micropuncture sets may be configured with:
- Nitinol core construction
- Stainless steel core construction
- Stainless steel coil reinforcement
Distal coil configurations may include:
- Standard stainless steel coil
- 7 cm gold tip
- 7 cm tungsten tip
Gold and tungsten tipped variants provide a softer distal segment to support atraumatic advancement in delicate vessels.
Guidewires supplied within micropuncture sets are configured specifically for access use and are not positioned as standalone catalogue wires.
Standard Configurations
Micropuncture sets are available in defined standard configurations aligned with commonly used vascular access workflows.
Standard dimensional specifications and component combinations are detailed in the product brochure.
Customisation
Custom micropuncture programs may include:
- Alternative guidewire constructions
- Modified distal tip configurations
- Custom stiffness profiles
- Procedure-specific kit assembly
- Bulk non-sterile supply for OEM integration
- Private label manufacturing
Custom configurations are evaluated to ensure dimensional compatibility and performance stability within the access system.
