Occlusion catheter system for partial occlusion or full occlusion

An occlusion catheter system for partial or complete occlusion of the aorta to preserve blood flow to a heart and brain of a patient, the occlusion catheter system comprising:

• a proximal hub having a single inlet and forming an internal inflation fluid pathway;
• a flow valve;
• a proximal catheter member in fluid communication with the inflation fluid pathway;
• a distal catheter member;
• an intervening, compliant occlusion balloon connecting the proximal catheter member with the distal catheter member;
• a lumen extending from the proximal hub through the proximal catheter member and into communication with the occlusion balloon;
• and
• a stiffener member having a proximal end and a distal end, the proximal end of the stiffener member being (i) located within and bonded to the proximal hub and (ii) spaced distally from the flow valve, the distal end of the stiffener member being secured within the distal catheter member,
• wherein, in an open position of the flow valve, the flow valve is configured to fluidly communicate an inflation device with the inflation fluid pathway, via the single inlet, for occlusion balloon inflation, and in a closed position of the flow valve, the flow valve is configured to block fluid communication between the inflation device and the inflation fluid pathway, the flow valve being selectively actuatable into each of the open and closed positions with the stiffener member extending distally from the proximal catheter member.

An occlusion catheter system for partial or complete occlusion of the aorta to occlude non-compressible hemorrhage in emergency or trauma environments where guidance imaging is typically not available, the occlusion catheter system comprising:

• a proximal hub forming an internal inflation fluid pathway;
• a flow valve having an inlet and an outlet, whereby the outlet of the flow valve is connected to an inlet of the proximal hub, the flow valve having an open position configured to fluidly communicate a syringe with the inflation fluid pathway of the proximal hub;
• a proximal catheter member extending from the proximal hub;
• a distal catheter member terminating in an atraumatic tip;
• an intervening, compliant occlusion balloon connecting the proximal catheter member with the distal catheter member;
• a length marking on an exterior of the proximal catheter section to indicate an insertion depth of the occlusion catheter;
• an inflation lumen originating from the proximal hub, in fluid communication with the inflation fluid pathway, and extending through the proximal catheter member and into fluid communication with the occlusion balloon;
• and
• a stiffener member having a proximal end and a distal end, the stiffener member being longitudinally solid from the proximal end to the distal end, the stiffener member extending within the inflation lumen, the occlusion balloon and into the distal catheter member, the proximal end of the stiffener member being located within and fixedly coupled to the proximal hub, the distal end of the stiffener member being fixedly coupled to the distal catheter member, wherein the proximal catheter member, the occlusion balloon and the distal catheter member have a greatest outer diameter of 6 Fr or less in an uninflated configuration.
