1. An intravascular system comprising:
- a sheath comprising a primary sheath lumen and a sensor sheath lumen, the sheath having a sheath length, wherein the sensor sheath lumen terminates at an opening along a distal end of the sheath, the opening located along an exterior of the sheath; and
a hub configured to couple to a proximal end of the sheath, wherein the hub comprises;
a primary hub lumen configured to be placed in fluid communication with the primary sheath lumen when the hub is coupled to the sheath;
a sensor hub lumen terminating at a sensor port and configured to be placed in fluid communication with the sensor sheath lumen when the hub is coupled to the sheath; and
a flushing lumen terminating at a flushing port and in fluid communication with the primary hub lumen;
wherein a transmission line is configured to be positioned within the sensor sheath lumen and the sensor hub lumen;
wherein the transmission line is configured to couple to a sensor positioned within the sensor sheath lumen at or adjacent the opening of the sensor sheath lumen along the distal end of the sheath, wherein the sensor is configured to detect a parameter of fluid passing into the opening from a space within a subject;
wherein the primary sheath lumen is separate from the sensor sheath lumen, such that the primary sheath lumen is not in direct fluid communication with the sensor sheath lumen and does not impinge on the sensor sheath lumen along the sheath length; and
wherein the primary hub lumen is separate from the sensor hub lumen, such that the primary hub lumen is not in direct fluid communication with the sensor hub lumen.

Abstract
Medical devices, perfusion systems, and methods for detecting a pressure within a space in a subject and for perfusion of fluid into a space in a subject. The space may be a fluid-filled space, or a space that is depleted of fluid due to an obstruction to fluid flow into the space. Methods for forming the medical devices.

14. An intravascular system comprising:
-
a sheath comprising a primary sheath lumen and a sensor sheath lumen, wherein the sensor sheath lumen terminates at an opening along a distal end of the sheath, the opening being located along an exterior of the sheath; wherein the sensor sheath lumen is not in direct fluid communication with the primary sheath lumen and does not impinge on the primary sheath lumen. a hub configured to couple to a proximal end of the sheath, wherein the hub comprises; a primary hub lumen; a sensor hub lumen; and a flushing lumen in fluid communication with the primary hub lumen; wherein the hub is configured to be coupled to the sheath; wherein the primary hub lumen is configured to be placed in fluid communication with the primary sheath lumen of the sheath when the hub is coupled to the sheath; wherein the sensor hub lumen is configured to be placed in fluid communication with the sensor sheath lumen when the hub is coupled to the sheath; wherein a transmission line is configured to be positioned within the sensor sheath lumen and the sensor hub lumen; wherein the transmission line is configured to couple to a sensor, the sensor being positioned within the sensor sheath lumen at or adjacent the opening of the sensor sheath lumen; and wherein the sensor is configured to detect a parameter of fluid passing into the opening from a space within a subject. - View Dependent Claims (15, 16, 17, 18, 19)
