A vascular introducer sheath device comprising a tubular main shaft and main hub attached to the proximal end of the main shaft. Attached to the proximal end of the main hub is a header hub having a first arm and second arm. The header hub is attached to the main hub in a releasably locked configuration and functionally detachable from the main hub. The header hub and main hub could together have a twist-on or snap-on mating mechanism. An example of such a mating mechanism is a male lock fitting on the header hub and a female lock fitting on the main hub. There could be a side port on the main hub and a side port on the header hub, wherein the side ports for the main hub and header hub are oriented on a same plane when the header hub and the main hub are in locked configuration.

An aspiration control device can have an aspiration control valve and a switch, button, slider, trigger, grip, lever, rotating wheel, rotating valve, handle or other interface for resizing the aspiration control valve. The aspiration control interface can be conveniently positioned and configured to be manipulated while simultaneously stabilizing a catheter and/or retracting an elongated member. The aspiration control device can be integrated with a hemostasis valve, integrated with a wire gripping device, and/or attached to an inlet, outlet, hose, pump, or syringe in series with an aspiration flow path.

A system includes a first port comprising a first inlet, a first outlet, a first fluid pathway extending from the first inlet to the first outlet, a second inlet, a second outlet, and a second fluid pathway extending from the second inlet to the second outlet. The system further includes one or more CSF catheters having a first lumen, a first distal opening in fluid communication with the first lumen, a second lumen, and a second distal opening in fluid communication with the second lumen. The one or more CSF catheters are, or are configured to be, operatively coupled with the first implantable device such that the first lumen is in fluid communication with the first fluid pathway and the second lumen is in fluid communication with the second fluid pathway. At least the first distal opening is configured to be placed in the CSF-containing space. The system further includes a second port having a third inlet, a third outlet, and a third fluid pathway extending from the third inlet to the third outlet. The system also includes a port catheter configured to operatively couple the third fluid pathway to the second fluid pathway.

The present disclosure describes a flow reversing valve, along with associated methods and systems for providing forward flow, reverse flow, and bypass flow modes of operation, and integrating them into patient treatment systems, including those used for treating and inducing hyperthermia.

A low profile catheter system includes a catheter hub with proximal, distal, and intermediate portions, a stabilization surface located on an underside, and a receptacle located within a top surface. A substantially linear flow path extends from an opening at the distal portion to an inlet located within the intermediate portion and allows fluid to flow between the distal and intermediate portions. The inlet of the flow path is located between the proximal and distal portions. A base connector has a fluid path extending through at least a portion of the base connector and between a first opening located nearer a first end and a second opening. The fluid path is fluidly connected to the inlet of the flow path and a second end of the base connector is retained within the receptacle by the proximal portion when the base connector is received by the receptacle.

A surgical port includes an end face comprising a channel extending through the end face, the channel having a cross section shaped to receive a surgical instrument cannula, and a lateral wall extending around a perimeter of the end face, the lateral wall and end face enclosing an open volume. An end portion of a wound retractor is received in the open volume of the surgical port and in engagement with an inner surface of the lateral wall, and the surgical port is configured to abut a body wall in an inserted position of the wound retractor through the body wall.
