Steerable Catheters & Deflectable Catheters
As an industry-leading catheter manufacturer, DUKE Extrusion has produces custom steerable catheters—often called deflectable catheters—that meet your unique specifications.
Steerable catheter delivery systems help to guide catheters, stent delivery systems, and therapeutic devices into the target location, and are particularly suited for navigating torturous anatomy. Common applications for steerable catheters include electrophysiology mapping, ultrasound imaging, general imaging, mitral valve repair, site-specific radiation, steerable balloon systems, and stent delivery systems.
DUKE’s Steerable Catheters
DUKE Extrusion can help you achieve a defined curve of deflection for your steerable catheter through the use of pull wires and the proper application of materials and support configurations. We can match the specific curve to a tip shape that you provide. We can also recommend deflection curves for medical catheter tubing that are suitable for accessing particular anatomies.
We manufacture steerable catheters from a wide range of materials. We will design your product with the best materials to meet all of your functional and dimensional requirements, including bend radius and wall thickness. DUKE Extrusion manufactures deflectable in a wide range of French sizes, from 2Fr through 40Fr.
A steerable catheter delivery system often includes a braid or coil reinforcement; laser cut hypotube can also be used for this purpose. PTFE liners are frequently utilized to improve inner lubricity. We can manufacture your custom deflectable catheters in numerous configurations and constructions. Ultra-thin wall deflectable catheters are available with all thicknesses as low as 0.007”. Options for deflectable catheters include PTFE-lined lumens and customized or standard handle configurations.
Multi-Directional Deflectable Catheters
DUKE Extrusion’s steerable catheters can be deflectable on up to four different planes—we can create unidirectional, bidirectional, 3- and 4-directional steerable catheters, according to your specific application. Deflection refers to the movement of the catheter tip, independent of the rest of the device.
Unidirectional Deflectable Catheters
A single-direction deflectable catheter features a tip that can be pulled into a defined curve via pull wires and anchor rings. Deflectable catheters are useful where highly angulated turns in target anatomy are encountered or where precise tip positioning is required.
Bidirectional Deflectable Catheters
The tips of two-direction deflectable catheters can be pulled in two opposing directions. This requires two pull wires, usually connected to a single anchor ring. Because they can be steered forward and backward, bidirectional deflectable catheters are especially useful where a sweep motion, with no rotational maneuvering, is desired for exact tip placement.
3- & 4-Directional Deflectable Catheters
These highly specialized deflectable catheters feature tips that can be pulled in multiple directions, usually using a special device handle with multiple pull wires attached. Multidirectional deflectable catheters can be maneuvered through challenging anatomy, such as multiple heart chambers.
