Guide Needles TRIZ Cases
- Curved Diaphragm Self-Sealing Catheter Valve
A curved flexible diaphragm with a traverse slit opens and closes automatically via pressure changes.
- Duckbill Valve Catheter Adapter Blood Control
Merged one-way and port valves eliminate manual occlusion to reduce blood exposure risks.
- Fluid-Mediated Ablation for Smooth Muscle Targeting
Permeable sheath delivers energy through fluid medium to impair smooth muscle while preserving endothelium integrity.
- Curved Introducer Sheath for CSF Space Navigation
A curved introducer sheath navigates the cerebrospinal fluid space, resolving delivery accuracy constraints in complex anatomical pathways.
- Balloon Catheter Bending Adjustment with Steering Handle
A balloon catheter steering handle rotates wires to bend the guide tube end.
- Dilation Catheter Removable Guide Member and Rotary Control
A dilation catheter assembly incorporates a removable guide member and rotary control mechanism for precise guidewire advancement.
- Coronary Sinus Guide Segmentation and Nitinol Reinforcement
Segmented coronary sinus guides with local nitinol reinforcement balance flexibility for altered anatomy against torqueability for precise placement.
- Tapered Introducer Sleeve Reducing Insertion Force
Segmented outer sleeve and inner cannula minimize tissue trauma while accommodating standard wire guides.
- Expandable Introducer Vessel Spasm Prevention
An expandable introducer transitions from a compressed profile to an expanded state using a dedicated support member.
- Flexible Endoscope Overtube with Inflatable Sealing Rings
An inflatable overtube creates a sealed compartment to improve ultrasound imaging quality by minimizing air interference while preventing fluid escape.
- Stent Graft Delivery Device Curvature Control
A pull wire mechanism bends a guide wire catheter to fit the thoracic arch, creating working space for branch vessel catheterization.
- Chest Tube Insertion Sheath with Pneumostatic Clamp
Tapered pneumostatic clamp maintains pleural pressure while the semi-rigid sheath enables precise chest tube positioning.
- Luer-Activated Blood Control Valve for IV Catheter Hub
An integrated blood control valve prevents clinician blood exposure during placement without adding manual procedure complexity.
- Blood Control Valve for Ported Catheter Adapter
Integrated port and blood control valves prevent leakage while allowing air venting through surface tension mechanisms.
- Expandable Catheter Pump Sheath Assembly for Aortic Valve Stability
Expandable catheter pump sheath assembly stabilizes impeller flow across the aortic valve via vessel contact zones.
- Guide Extension Catheter Tapered Design for Vessel Alignment
Tapered geometry and nested configuration reduce stent-device interaction while ensuring precise delivery of interventional devices.
- Expandable Sheath for Intravascular Catheter Insertion
A perforated expandable sheath adapts to different catheter sizes, reducing vascular trauma and blood loss during intravascular procedures.
- Blunt Dissection Catheter for Crossing Vascular Occlusions
A Blunt Dissection Catheter creates a dissection track through vascular occlusions using atraumatic spreading members.
