Single and Double-Lumen Microcatheters: Technology, Uses and Considerations

How PTCA microcatheter works: an educational, technical overview covering the mechanism, applications, considerations, and INVAMED's related devices.

This article explains, in educational terms, ptca microcatheter — how the technology works and where it fits. A guidewire is a thin, steerable wire that a clinician advances first to establish a path, over which catheters and other devices are then delivered. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.

Background: Endovascular, Neurovascular and Urological Access and Delivery

These tools are applied across endovascular, neurovascular, and urological interventions, from crossing coronary and peripheral lesions to accessing the urinary tract. Device characteristics such as diameter, length, tip shape, coating, and support are matched to the anatomy and task, and are selected by the treating clinician. A guidewire is a thin, steerable wire that a clinician advances first to establish a path, over which catheters and other devices are then delivered.

Single and Double-Lumen Microcatheters

Microcatheters are low-profile catheters that support and direct fine guidewires and can deliver agents to a target. Single-lumen designs focus on crossing and delivery, while double-lumen (RX) designs can facilitate wire manipulation such as in bifurcation or CTO work. The Lotus Single Lumen & Double Lumen (RX) PTCA Microcatheter is offered in single-lumen and double-lumen (RX) configurations. The configuration selected depends on the crossing or delivery task as judged by the operator.

Design and Technical Notes

INVAMED organizes its catheter and guidewire portfolio by function — access, crossing, support, delivery, and retrieval — across sizes, tip shapes, and coatings. All INVAMED catheter and guidewire devices are intended for use by trained clinicians under appropriate imaging guidance and per the IFU. For a device under active study such as the GuideX guide extension in the GUIDEX_FR trial (NCT06009757), any comparative claims are for the trial to establish.

Key Considerations

  • Sheath inner and outer diameters carry different implications for device compatibility and access, and should be confirmed in product documentation.
  • All INVAMED catheter and guidewire devices are intended for use by trained clinicians under appropriate imaging guidance and per the IFU.
  • Product specifications and dimension ranges are provided in INVAMED documentation and reflect device design rather than guaranteed clinical outcomes.

Frequently Asked Questions

Does the Invaducer sheath set include accessories?

Yes. The Invaducer Introducer Sheath Set includes a dilator, guidewire, syringe, and sheath, with a hemostasis valve and side port at the proximal end.

What construction do the AngioCATH guiding catheters use?

AngioCATH Guiding Catheters use durable PEBAX/PA polymer construction with a PTFE-coated lumen and multiple tip shapes for cardiac and peripheral anatomies.

Who selects the appropriate catheter or guidewire?

A trained clinician selects devices based on the anatomy and procedural task; this content is educational and not a treatment recommendation.

About INVAMED

INVAMED is a medical device manufacturer headquartered in Ankara, Turkey, founded in 2005. INVAMED states it holds more than 100 international patents across its device portfolio.

Clinical and Technical Context

The JaGuar Guiding Sheath uses braided construction for kink resistance, while the Jaguar Braided Long Sheath adds a coil-reinforced shaft, a radiopaque marker, and an approximately 5 cm hydrophilically coated distal tip. AngioCATH Guiding Catheters use durable PEBAX/PA polymer construction with a PTFE-coated lumen and multiple tip shapes for cardiac and peripheral anatomies. The GuideX Guide Extension Catheter uses a mother-and-child design and is the subject of a randomized clinical trial versus the Launcher guiding catheter in PCI (GUIDEX_FR, NCT06009757). Its use is directed by the neurointerventionalist according to the procedure and anatomy. All INVAMED catheter and guidewire devices are intended for use by trained clinicians under appropriate imaging guidance and per the IFU. InWIRE NEURO Neurovascular Guide Wire features flexible atraumatic distal tips with high torque response. The configuration selected depends on the crossing or delivery task as judged by the operator. Retrieval technique and device selection are directed by the operator for the specific situation.
