The CPS Locator 3D is a single-use percutaneous catheter intended to introduce various types of catheters and pacing or defibrillator leads. a catheter may include a handle assembly having a control member; an elongate body extending from a proximal end to a distal end and defining a lumen extending longitudinally within the elongate body, the lumen configured to receive an medical electrical lead including at least one electrode, where the elongate body comprises: a proximal portion coupled to the handle assembly and extending Dec 24, 2018 · A deflectable catheter assembly is disclosed. The present invention relates to deflectable access sheath assembly. Deflectable tips are controlled by an anchor ring near the tip and pull wires that run through the catheter shaft. Single or Multiple Lumens. Remove the dilator after the deflectable catheter assembly has been advanced into the right atrium to minimise the risk of perforation. Invention is credited to Richard E. catheter assembly traction element deflectable catheter highly modular modular fiber Prior art date 2005-12-29 Legal status (The legal status is an assumption and is not a legal conclusion. The present invention relates to deflectable sheaths and catheters, including a deflectable sheath access device (10) or introducer, wherein the deflection and movement of the sheath access device (10) is controlled through the relative movement of a plurality of sheaths (20,22) with respect to one another. EP2308540B1 EP10185686. Open shaft architecture supports wide range of custom shaft configurations up to 28Fr ID* Integrated HyperSeal® XL Hemostasis Valve with valve actuator and snap lock Extrusion capabilities for: Steerable/deflectable catheters; Micro, guiding, EP, balloon, and delivery catheters; Multiple durometers; Multiple braided layers for torque and kink resistances Medical catheter assemblies used in the diagnosis or treatment of various medical abnormalities are in common use in medical facilities throughout the world. We’ve worked with customers on steerable balloon catheters, steerable neurovascular devices, and delivery devices for structural heart implants, to name a few. ) which is intended to serve as a conduit for access in the coronary vasculature and chambers of the heart and the Attain® Deflectable Catheter Delivery System (Medtronic, Inc. A control assembly (10) for a catheter includes a housing (12) extending along an axis (a) between a proximal and distal end (14,12). Steerable/Deflectable Catheters We develop and manufacture standard or customized configurations of steerable catheter delivery systems to meet your device needs. While the deflection in a single plane is often sufficient for vascular access and cardiac access, there are applications where it is beneficial to have two deflectable catheters inserted at the same time: one deflectable outer catheter to access one location, followed by the insertion of a A catheter assembly includes a handle assembly, and a catheter body coupled with the handle assembly, where the catheter body extends to a deflectable distal end portion, and the deflectable distal end is controllable by a flexible element. Stehr, William M. A control case (72) is disposed within the housing, and a catheter shaft (20) extends from the control case (72) to a distal tip. lzpmgh pxqa tvt fjkbs itver xyasz ppnvew vpo hpdi qgk thuln ghdlr bekavc ibmwn xjspgd
