- It also enabled the delivery of 1-mm gelatin particles for embolization.
Conclusions:
- The novel slippery coaxial catheter device offers a safe and effective solution for complex vascular interventions.
- This technology enhances the precision of chemotherapy infusion and embolization procedures.
Abstract:
A slippery coaxial, 3-F catheter device was developed for selective angiography, embolization, and infusion of chemotherapeutic agents. The device comprises three parts: an 0.018-inch, plastic-coated guide wire; a 3-F coaxial catheter; and a 6.5-F guiding catheter. Both the guide wire and coaxial catheter are coated with hydrophilic polymer, which becomes slippery when immersed in water. Experience with four patients indicates the new coaxial catheter device is capable of traversing tortuous vessels smoothly and safely, and it permits infusion of chemotherapeutic agents and 1-mm gelatin particles.
