1. A catheter connector system, comprising:
- a catheter hub, comprising;
a cannula on a proximal end of the catheter hub sized for insertion into a lumen of a first tubular element,a bore to communicate a fluid from the cannula through the first tubular element,a housing on a distal end of the catheter hub, anda distal interface having;
a retention collar,a deformable sealing element positioned within the retention collar, anda tapered seal post longitudinally fixed relative to the catheter hub and positioned within the deformable sealing element,each of the retention collar, deformable sealing element, and tapered seal post extending past a distal end of the housing; and
a coupling member, comprising;
a cavity receiving at least a portion of the distal interface of the catheter hub,at least one locking member formed on an outer surface of the cavity, the locking member having a ledge formed on an inner surface of the cavity to engage at least a portion of the retention collar,an actuating member disposed within the cavity to engage at least a portion of the deformable sealing element, anda bore to communicate a fluid from the catheter hub through the coupling member into a second tubular element.

Abstract
A catheter connection system is disclosed. In one embodiment, a catheter connection system may include at least two components and a deformable sealing element positioned between the at least two components configured to allow, upon deformation, fluid flow through the at least two components. In another embodiment, the catheter connection system may include a sealing element positioned between at least two components, wherein the components are coupled to one another by a locking member.
