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.

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; anda 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. 2. The catheter connector system of claim 1, wherein the cavity, the deformable sealing element, the distal interface of the catheter hub, the retention collar, and the actuating member are substantially annular. 3. The catheter connector system of claim 1, wherein the locking member and the ledge are integrally formed on the surface of the cavity. 4. The connector system of claim 1, wherein the deformable sealing element surrounds and abuts the seal post to seal a bore of the connector hub. 5. The connector system of claim 4, the connector system comprising a sealed configuration where a sealing surface of the deformable sealing element is in contact with the seal post to prevent fluid flow through the connector hub, and an open configuration where the deformable sealing element is deformed such that the sealing surface is longitudinally displaced with respect to the connector hub and the seal post to open a fluid flow path through the connector hub. 6. The catheter connector system of claim 1, wherein a distal end of the tapered seal post, deformable sealing element, and retention collar are longitudinally co-extensive in a sealed position. 7. The catheter connector system of claim 6, wherein the deformable sealing element is retained between the retention collar and the housing of the catheter hub to longitudinally fix a proximal end of the deformable sealing element with respect to the catheter hub. 8. The catheter connector system of claim 7, wherein the retention collar comprises an internal indention creating an open space between the deformable sealing element and the retention collar to provide a volume for the deformable sealing element to deform when engaged by coupling member.
