  • Publication number: 20220323083
    Abstract: An occlusion catheter system includes an inflation catheter member and an occlusion balloon. The proximal and distal balloon ends are connected to the inflation catheter between the proximal and distal catheter ends. A distal pressure sensor is attached to the inflation catheter member between the proximal balloon end and the atraumatic tip. An inflatable spine is connected to the inflation catheter. The proximal spine end is connected to the inflation catheter near the proximal balloon end and the distal spine end is connected to the inflation catheter near the distal balloon end. The occlusion balloon and the inflatable spine are configured to define blood flow channels with the internal surface and the external balloon surface when the occlusion catheter system is at least partially positioned in the vessel and the occlusion balloon and the inflatable spine are in a partially inflated configuration.

  • Publication number: 20210290243
    Abstract: An occlusion catheter system for full or partial occlusion of a vessel having a vessel diameter includes a proximal catheter shaft having a proximal lumen and a hypotube positioned partially within the proximal lumen and spaced from the proximal catheter shaft. The catheter system also includes a distal catheter shaft attached to a distal end of the hypotube and an occlusion balloon connected at a proximal end to the proximal catheter shaft and at a distal end to the distal catheter shaft. The occlusion balloon is configured to define flow channels with inner surfaces of the vessel at folds in the occlusion balloon when the occlusion balloon is partially inflated and in engagement with the inner surfaces.

  • Patent number: 10885813
    Abstract: A body model system for temporary hemorrhage control training and simulation includes a frame simulating at least a torso of the body having a hollow portion, a simulated artery positioned in the hollow portion, a thigh patch mounted to the frame proximate the hollow portion, a pump connected in fluid communication with the simulated artery and a reservoir connected in fluid communication with the simulated artery and the pump. The frame is substantially rigid. The thigh patch is constructed of a resilient material that is pierceable by a needle. The simulated artery extends through the thigh patch. The pump is configured to produce a pulsatile flow in the simulated artery.

  • Patent number: 10806903
    Abstract: A handheld vascular access device for gaining access to a patient's vessel includes a hub, a plurality of access needles and a manifold. The hub has an inner wall and side walls that define a plurality of ports. Each of the plurality of ports has a proximal port end and a distal port end. The proximal port ends define a proximal cross-sectional area and the distal port ends define a distal cross-sectional area. The proximal cross-sectional areas are greater than the distal cross-sectional areas. Each of the plurality of ports taper from the proximal port end to the distal port end. The plurality of hollow access needles is arranged along a plane and fixedly coupled to the distal end of the hub. Each of the plurality of needles has a tip. The manifold removably engages the hub at the proximal end of the hub.

  • Publication number: 20200276419
    Abstract: An access device includes a body, a needle and a guidewire. The body has a guidewire channel extending from a distal end of the body toward the proximal end. The guidewire channel opens into a funnel-like port having a proximal port diameter greater than a distal port diameter. The distal port diameter is substantially the same as a guidewire channel diameter. The needle has a tip, a proximal end and a needle lumen. The proximal end of the needle is removably secured to a distal end of the body in an assembled configuration. A guidewire has a front end portion positioned in the guidewire channel in an initial configuration and a guidewire diameter. The guidewire channel diameter is greater than the guidewire diameter and the guidewire channel facilitates blood flow between the guidewire and an internal surface of the guidewire channel when the guidewire is positioned in the guidewire channel.
