This is a technical overview of an INVAMED device within the embolization portfolio. Common applications described in the literature include peripheral aneurysms, arteriovenous fistulas (AVFs) and malformations (AVMs), gastrointestinal or intestinal bleeding, pelvic congestion, varicocele, and endoleaks after aortic repair. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Endovascular Embolization
Whether embolization is appropriate, and which agent and delivery system are chosen, is a clinical decision that weighs the target vessel, surrounding anatomy, and overall condition of the patient. Embolization is an endovascular technique in which an occluding material is delivered through a catheter to intentionally block blood flow in a target vessel, and it is used across a broad range of indications. Because embolization is generally intended to be permanent, careful vessel selection and sizing are emphasized so that only the intended territory is occluded.
Spider Peripheral Detachable Coil System (Detachable & Pushable): Overview
A detachable coil kit for embolization of peripheral aneurysms, AV fistulas, or abnormal vessels, providing stable coil packing with controlled mechanical detachment (official meta description; site canonical spells it 'Spider Peripheral Detactable Coil System').
Technical Specifications

| Specification | Detachable and pushable coil configurations with controlled mechanical detachment |
| Specification | Coil family shared with Spider intracranial line: platinum-tungsten (92/8% alloy), 2-30 mm coil diameters (per invamed.com content, surfaced via search index) |
How It Works and Where It Fits
INVAMED organizes its embolization portfolio around the mechanism of occlusion, offering detachable and pushable coils, a fiber-filled vascular plug, dedicated delivery catheters, a flow-modulating device, and a non-adhesive liquid agent. Each device is intended for use by trained interventionalists under imaging guidance and per the IFU. Precise embolization depends on delivery catheters and microcatheters that can navigate tortuous vessels and position the occluding agent at the intended site. Liquid embolic agents are injectable materials that solidify within the vessel after delivery, allowing them to penetrate and cast complex networks such as arteriovenous malformations.
Key Considerations
- Because embolization is usually intended to be permanent, precise vessel selection and sizing are emphasized so that only the intended territory is occluded.
- Detachable designs allow the operator to confirm position before committing, which can be valuable near sensitive branches.
- Catheter and microcatheter compatibility with the chosen coil, plug, or agent is confirmed before delivery to support controlled deployment.
Frequently Asked Questions
Is embolization a substitute for surgery?
INVAMED's MultiBEAM product page states the transcatheter plug "provides great benefit instead of surgical treatment in suitable patients" with reportedly high success and low complication rates, but suitability is always a clinical determination.
Does INVAMED make a liquid embolic agent?
Yes; the Libro Non-Adhesive Embolization Agent is cross-listed in INVAMED's embolization portfolio as a non-adhesive liquid agent, with delivery determined by the operator.
Who decides which embolization device to use?
A trained interventionalist selects the agent and delivery system based on the target vessel and indication; this article is educational and not a treatment recommendation.
About INVAMED
INVAMED is a medical device manufacturer headquartered in Ankara, Turkey, founded in 2005. INVAMED operates a dedicated R&D center (INVAcenter) focused on minimally invasive device development.
Clinical and Technical Context
The occluding agents fall into families such as detachable coils, vascular plugs, liquid embolic agents, and particles, each with a different mechanism of vessel closure. Embolization is an endovascular technique in which an occluding material is delivered through a catheter to intentionally block blood flow in a target vessel, and it is used across a broad range of indications. INVAMED's Spider Peripheral Detachable Coil System offers both detachable and pushable configurations with controlled mechanical detachment; per invamed.com content surfaced via the search index, the shared Spider coil family uses a platinum-tungsten (92/8%) alloy with coil diameters spanning roughly 2 to 30 mm. Because embolization is usually intended to be permanent, precise vessel selection and sizing are emphasized so that only the intended territory is occluded.
