This article explains, in educational terms, guidewire 0.035 — how the technology works and where it fits. Access is commonly established with an introducer sheath, which creates a stable, valved entry point through the vessel wall for exchanging devices. 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
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. These tools are applied across endovascular, neurovascular, and urological interventions, from crossing coronary and peripheral lesions to accessing the urinary tract. 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.
0.035 and 0.038 inch Guidewires
The 0.035 inch and 0.038 inch guidewire sizes are common workhorse diameters in peripheral and general endovascular access. Larger-diameter wires generally provide more support for advancing catheters and sheaths. InWIRE Peripheral Guidewires provide 0.035 inch and 0.038 inch options with a choice of nitinol or stainless steel cores. Which diameter is used depends on the vessel, the devices being delivered, and clinician preference.
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. Sheath inner and outer diameters carry different implications for device compatibility and access, and should be confirmed in product documentation.
Key Considerations
- All INVAMED catheter and guidewire devices are intended for use by trained clinicians under appropriate imaging guidance and per the IFU.
- Device sizing across French, inch, and centimeter units must be matched to the vessel, the access site, and the devices being delivered, as determined by the clinician.
- Sheath inner and outer diameters carry different implications for device compatibility and access, and should be confirmed in product documentation.
Frequently Asked Questions
What is the GuideX guide extension catheter?
GuideX is INVAMED's mother-and-child guide extension catheter, which is the subject of a randomized clinical trial versus the Launcher guiding catheter in PCI (GUIDEX_FR, NCT06009757).
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.
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.

Clinical and Technical Context
INVAMED offers a comprehensive catheter and guidewire portfolio spanning sheaths, guidewires, guiding and support catheters, microcatheters, and retrieval devices. Product specifications and dimension ranges are provided in INVAMED documentation and reflect device design rather than guaranteed clinical outcomes. Sheath inner and outer diameters carry different implications for device compatibility and access, and should be confirmed in product documentation. Whether a guide extension is used is determined by the operator based on the procedural needs. Catheters and guidewires are the working tools of minimally invasive procedures, used to gain vascular access and navigate to a target inside the body. The appropriate tip shape and catheter are chosen by the clinician for the target anatomy. Sheath French size and length are matched to the intended devices and access site by the clinician. These tools are applied across endovascular, neurovascular, and urological interventions, from crossing coronary and peripheral lesions to accessing the urinary tract.
