Summary: The Envoy Guiding Catheter by Cordis Neurovascular is used in neurovascular procedures. It is primarily used for guiding other devices during endovascular treatments. Key evidence highlights its use in complex catheterizations and embolization procedures.
The Envoy Guiding Catheter was cleared by the FDA through the 510(k) pathway on July 23, 1997. It is manufactured by Cordis Neurovascular and classified as a Class II device.
What It Is
The Envoy Guiding Catheter is a medical device used to facilitate the introduction and guidance of other devices in neurovascular procedures. It is designed to provide support and stability during endovascular interventions.
Clinical Applications
Commonly used in procedures involving the treatment of intracranial aneurysms and other neurovascular conditions, the Envoy Guiding Catheter aids in the precise placement of microcatheters and other interventional tools.
Evidence Summary
The available literature includes four studies, ranging from case series to prospective trials, published between 1997 and 2020. These studies explore the catheter's use in various neurovascular interventions.
Reported Outcomes
Published studies report successful use of the Envoy Guiding Catheter in complex neurovascular procedures, including embolization of intracranial aneurysms and balloon-assisted coiling. The catheter has been noted for its ability to accommodate multiple microcatheters simultaneously, enhancing procedural efficiency.
Safety Profile
Reported complications include difficulties in catheterization due to acute vessel angulation, as noted in some cases. However, the catheter's design generally supports safe and effective navigation in challenging anatomical scenarios.
Evidence Limitations
The evidence is limited by the small number of studies and the variability in study design. Further research is needed to establish long-term outcomes and to compare the Envoy Guiding Catheter with other similar devices in larger, randomized trials.
