摘要： A device for axial and rotational locking of a dual catheter system and methods of the same. The system includes an outer catheter and an inner catheter adapted to be inserted into the outer catheter. The outer catheter extends along a catheter axis and includes an outer catheter shaft and an outer catheter hub. The inner catheter includes an inner catheter shaft and an inner catheter hub. The system also includes an intermediate hub located between the inner and outer catheters. The intermediate hub includes a deformable component positioned around at least a portion of the inner catheter. The deformable component is adapted to be inserted into the outer catheter hub such that the inner catheter is restricted, rotationally about and axially along the catheter axis, relative to the outer catheter.

摘要： Systems and methods for manufacturing an elongate medical device including various surface features. The system including a heating cartridge, a heating element, a filament handling system, a substrate handling system, a controller, and one or more additional components adapted to form the surface features on the medical device. The heating element melts a filament material within the heating cartridge to form a jacket of the medical device and the one or more additional components engages the outer surface of the jacket to create surface features.

摘要： Systems and methods for manufacturing elongate medical devices including internal components embedded between multiple jacket layers. The system including a heating cartridge, a heating element, a filament handling system, a substrate handling system, and a controller to feed and melt each of the filaments for forming the multiple jacket layers. The system may include a single heating cartridge adapted to make multiple passes to form a first and second jacket or multiple heating cartridges that sequentially form a first and second jacket.
