Abstract: A system for measuring a pressure in a vein includes a needle sized and shaped to be inserted through a working channel of an endoscope. The needle is extending longitudinally and including a channel extending longitudinally therethrough. The system also includes a pressure sensing device including a longitudinally extending body sized and shaped to be slidably inserted through the channel of the needle and a sensor mounted on a distal portion of the body and connected to a proximal portion of the pressure sensing device via a connection cable. The sensor is configured to detect information corresponding to a pressure of a flow of blood through a vein.

Abstract: A medical catheter with improved structural integration and performance is disclosed. The catheter features a flexible shaft with a reinforcing braid and a polymeric jacket. Structural elements, such as a reinforcing assembly and an articulation structure, are positioned within the shaft and mechanically connected to the polymeric jacket. The connection is formed by creating windows in the polymeric jacket to expose the underlying reinforcing braid and disposing an attachment material through the windows and the braid into circumferential grooves of the structural elements. The attachment material fills the grooves, interlocking the structural elements with the braid and creating a strong, seamless bond with the polymeric jacket. This approach enhances force transmission, steering control, and overall catheter performance.
