FLUID SEALING MECHANISM FOR A CATHETER

This abstract first appeared for US patent application 18969024 titled 'FLUID SEALING MECHANISM FOR A CATHETER

Original Abstract Submitted

Devices and methods for selectively directing fluid flow through lumens of a catheter in order to effectively flush and/or de-air specified lumens of the catheter are disclosed. As one example, an assembly comprises a catheter including a first shaft and a second shaft extending through the first shaft. The assembly further comprises a sealing mechanism including a first seal disposed around a distal end portion of the first shaft, a second seal disposed around a portion of the second shaft that extends distal to the first shaft, and a cavity disposed within a housing of the sealing mechanism between the first seal and the second seal. A distal end of the first shaft is disposed within the cavity and the cavity is fluidly sealed by the first seal and the second seal such that fluid from a first lumen of the first shaft cannot exit the cavity.
