Successful embolization depends not only on the embolic device itself but on the delivery system used to reach the target vessel. INVAMED's MicroDELIVERY Embolization Catheter is a microcatheter system designed specifically for therapeutic embolization and diagnostic angiography in peripheral vessels, engineered to combine procedural control with the flexibility needed to navigate tortuous vascular anatomy. This overview summarizes the device's design intent for interventional radiologists.
What Is the MicroDELIVERY Catheter?
MicroDELIVERY is a microcatheter system designed to support therapeutic embolization procedures as well as selective angiographic imaging in peripheral vessels. Because embolic devices such as vascular plugs and coils are deployed through the microcatheter lumen, the catheter's trackability, kink resistance, and distal flexibility directly influence how reliably the physician can reach and treat the intended target.
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
What Are the Key Design Features?
MicroDELIVERY is engineered around several design priorities relevant to embolization procedures:
- Kink resistance — the catheter shaft is designed to maintain lumen patency even when navigated through tortuous or angulated vascular pathways, helping preserve the ability to deliver embolic devices without interruption
- Distal flexibility — the distal segment is designed to conform to small, winding peripheral vessels, supporting access to distal target sites
- Control with ease of use — the catheter is engineered to provide predictable torque response and pushability, supporting precise catheter tip positioning during embolic delivery
- Compatibility with embolic devices — designed to accommodate coils, plugs, and other embolic materials used in peripheral embolization procedures
Why Does Microcatheter Selection Matter in Embolization?
Microcatheter selection is an important planning consideration because the target vessel's diameter, tortuosity, and distance from the access site all influence which catheter profile and length are appropriate. A catheter with inadequate trackability may struggle to reach distal or angulated targets, while a catheter without sufficient kink resistance could compromise the ability to deliver coils or plugs reliably during the procedure.
Interventional radiologists typically select a microcatheter based on:
- Distance from the vascular access site to the target vessel
- Degree of vessel tortuosity along the intended pathway
- Compatibility with the specific embolic device planned for use (coil diameter, plug delivery profile)
- Whether diagnostic angiographic runs are needed through the same catheter before embolization
How Does This Fit Into the Broader Embolization Workflow?
MicroDELIVERY is typically used in conjunction with a guiding catheter or sheath placed at the primary vascular access site, with the microcatheter then advanced coaxially to the target vessel. Once positioned, the physician confirms placement with angiography before deploying the selected embolic device. As with all embolization equipment, device selection and technique are determined by the treating physician based on the specific clinical case.
Frequently Asked Questions
What procedures is the MicroDELIVERY catheter designed for?
MicroDELIVERY is designed to support both therapeutic embolization procedures and diagnostic angiography within peripheral vessels.
Can MicroDELIVERY be used with both coils and vascular plugs?
The catheter is designed for compatibility with a range of embolic devices, including coils and plugs; specific compatibility details are outlined in the official Instructions for Use.
Why is kink resistance important in an embolization catheter?
Kink resistance helps ensure the catheter lumen remains patent during navigation through tortuous vessels, which is essential for reliably delivering embolic devices to the target site without procedural delay.
