Designed for Reliable Peripheral Angioplasty Performance
Peripheral vascular disease treatments demand devices capable of navigating challenging vessel anatomy while delivering consistent dilatation force. The Mustang™ balloon catheter is specifically designed for peripheral PTA procedures, addressing lesions found in:
- Iliac arteries
- Femoral arteries
- Popliteal arteries
- Tibial and peroneal vessels
- Subclavian arteries
- Renal arteries
- Native and synthetic AV dialysis fistulae
- Post-stent deployment dilatation procedures
The catheter enables physicians to safely expand narrowed vessels, restore blood flow, and optimize stent placement when required.
Advanced Balloon Material Technology
One of the most notable features of the Mustang™ system is the NyBax™ balloon material, a proprietary co-extrusion of nylon and Pebax®. This material combination provides several procedural advantages:
High Pressure Capability
The balloon maintains structural integrity even at elevated pressures, enabling treatment of resistant or fibrotic lesions while minimizing the risk of balloon rupture.
Excellent Rewrapping Performance
After inflation, the balloon folds efficiently, simplifying catheter withdrawal and reducing friction within the sheath and vessel.
Controlled Compliance
The balloon delivers predictable expansion characteristics, allowing clinicians to achieve precise vessel sizing during angioplasty.
This balance of strength and flexibility is essential in modern PTA balloon catheter systems.
Enhanced Deliverability and Navigation
Peripheral interventions often involve tortuous or calcified vascular pathways. The Mustang™ catheter is engineered for smooth device advancement through challenging anatomy.
Low Entry Profile
The catheter’s lesion crossing profile is only slightly larger than the guidewire, enabling efficient lesion access and reducing resistance at stenotic segments.
Hydrophilic Coating
The shaft coating minimizes friction, improving catheter trackability through vascular structures and sheath systems.
Smooth Pushability and Torque Response
The shaft construction ensures controlled movement, supporting accurate positioning during intervention.
These characteristics collectively reduce procedure time and enhance procedural success rates.
Accurate Positioning Under Fluoroscopy
Precise balloon placement is critical in angioplasty procedures. The Mustang™ catheter includes radiopaque platinum-iridium markers positioned to indicate balloon working length clearly under fluoroscopic imaging.
This enables physicians to:
- Accurately center the balloon within the lesion
- Reduce geographic miss
- Improve treatment precision
- Optimize stent post-dilatation
Improved visibility contributes to safer and more efficient procedures.
Compatibility with Standard Clinical Equipment
The catheter integrates seamlessly with commonly used vascular intervention equipment:
- Compatible with 0.035″ guidewires, widely used in peripheral procedures
- Works with 5F or larger introducer sheaths
- Suitable for standard inflation devices
- Supports use across multiple vascular access strategies
This compatibility simplifies adoption and reduces the need for workflow modifications.
Clinical Applications
The Mustang™ PTA balloon dilatation catheter is indicated for use in multiple peripheral vascular treatments, including:
Peripheral Artery Disease Treatment
Enables vessel widening in stenosed peripheral arteries to restore circulation.
Dialysis Access Maintenance
Used in treatment of obstructive lesions in AV fistulae and grafts to maintain dialysis access functionality.
Stent Optimization
Ideal for post-deployment balloon expansion of both balloon-expandable and self-expanding stents.
Multi-Segment Lesion Treatment
Suitable for treating short-segment lesions requiring controlled dilatation.
Sterility and Packaging Assurance
Each catheter is supplied in original manufacturer packaging, ensuring:
- Sterility at point of use
- Protection during transport and storage
- Device integrity until procedure time
Packaging integrity is crucial in maintaining compliance with hospital and clinical sterilization protocols.
