1. A method comprising:
- forming an elongated body having a wall that defines a first lumen, a stiffener embedded in the wall, and a sensor lumen positioned in the wall, where the sensor lumen is not in direct fluid communication with the first lumen and does not impinge on the first lumen, the elongated body has a first end and a second end, and the first lumen extends from the first end to the second end such that both the first and second ends are open; and
positioning a sensor at least partially in the sensor 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.

30. A method comprising:
-
positioning one or more of; a first lumen mandrel; a stiffener; a second lumen mandrel; a first lumen tube; a second lumen tube; and a shrink wrap material such that the stiffener is outside of the first lumen mandrel, the first lumen tube is outside of the stiffener, the shrink wrap material is outside of the first lumen tube, and both the second lumen mandrel and the second lumen tube are inside of the shrink wrap material, thereby forming a combination; heating the combination such that a melting temperature of the first lumen tube is reached and such that an activation temperature of the shrink wrap material is reached, the heating being sufficient to form an elongated body having a wall defining a first lumen, the elongated body also having a second lumen positioned in the wall; after the heating, removing the second lumen mandrel leaving the second lumen formed at least in part by the second lumen tube; and positioning a sensor at least partially in the second lumen; where the elongated body has a first end and a second end, and the first lumen extends from the first end to the second end such that both the first and second ends are open. - View Dependent Claims (31)

57. A medical device comprising:
-
an elongated body having a wall that defines a first lumen, a stiffener embedded in the wall, and a sensor lumen positioned in the wall; and a sensor positioned at least partially in the sensor lumen; where the sensor lumen is separate from the first lumen so as not to be in direct fluid communication with the first lumen and does not impinge on the first lumen, the elongated body has a first end and a second end, and the first lumen extends from the first end to the second end such that both the first and second ends are open. - View Dependent Claims (58, 59, 60, 61, 70, 72, 73, 74, 75)

82. A medical device comprising:
-
a body configured as a hub for connection to an elongated tube, the body including a primary lumen, a side arm that includes a flushing lumen that is in direct fluid communication with the primary lumen, and an embedded transmission line that is not in direct fluid communication with the flushing lumen or the primary lumen within the body; and a valve configured to seal the primary lumen. - View Dependent Claims (83, 84)

86. A medical device comprising:
-
an elongated body having a passageway, a distal end, and a proximal end; and a pressure sensor attached to the elongated body, the pressure sensor having a length along any axis that is not greater than 2 mm, the pressure sensor being configured to detect a fluid pressure and output one or more signals representative of the detected fluid pressure where the elongated body includes a region that thermally insulates the passageway.
