Latest Patent Applications

Andrew Cragg's latest patent application is titled "CATHETERS AND DEVICES AND SYSTEMS INCORPORATING SUCH CATHETERS." This application describes a catheter that features a jacket defining a lumen and a helical support. The catheter consists of a proximal portion and a distal portion, with the distal portion having a corrugated outer surface for at least some of its length. A transition portion is designed to have a flexural stiffness that is less than that of the distal portion and more than that of the proximal portion. This transition portion optimizes flexural stiffness through features of the jacket, including the geometry of jacket corrugations or overlapping tubular layers. The distal end of the distal portion may include an extension of liner material folded over to provide a particularly soft tip. In other examples, the liner is terminated before the distal tip. The catheter is particularly suited for use in an aspiration device with a flow restrictor, and an aspiration system may employ the catheter with a pump that dynamically applies negative or positive pressure to optimally aspirate a clot.

Conclusion

Andrew Cragg is an innovative inventor whose work in catheter technology has the potential to impact medical devices significantly. His latest patent application showcases his dedication to improving catheter design and functionality.
