Sheath with sensing capabilities
First Claim
1. An elongated member comprising:
- a valve apparatus;
a first passageway extending along a single longitudinal axis from a first proximal end to a first distal end, the first distal end located at a distal end of the elongated member, the first proximal end configured to couple to the valve apparatus, wherein the valve apparatus is configured to seal around a device that is inserted through the valve apparatus and into the first passageway, wherein the first passageway comprises a first diameter and a first length, wherein the valve apparatus comprises a membrane that extends at least partially across the first passageway to allow other devices to be introduced through the first passageway while preventing fluid from flowing out of the first proximal end of the first passageway;
a second passageway comprising a generally circular cross-section and further comprising a second diameter and a second length; and
a detector positioned at least partially within and along a distal end of the second passageway such that the detector is at least partially within a portion of the elongated member;
wherein the first passageway and the second passageway are fluidly separate from each other and located along different longitudinal axes along an entire length of the elongated member; and
wherein the first and second passageways are adjacent each other for at least a portion of the elongated member.

Abstract
Disclosed are sheaths that comprise a first sheath member having a first passageway, a first length, and a first proximal end defined by a first valve apparatus configured to seal the first passageway, the first passageway having a first passageway diameter at a location in the first passageway; and a second sheath member coupled to the first sheath member, the second sheath member having a second passageway and a second length, the second passageway having a second passageway diameter at a location in the second passageway; where the first passageway and the second passageway are separate from each other and not co-axial, the first length is different from the second length, and the first and second sheath members are positioned beside each other for a portion of their first and second lengths.

6. An elongated member comprising:
-
a valve; a first passageway extending from a first proximal end to a first distal end, the first proximal end being configured to couple to the valve, wherein the first passageway comprises a first diameter and a first length, wherein the valve comprises a membrane that extends at least partially across the first passageway to allow an at least one other device to be introduced through the first passageway while preventing fluid from flowing out of the first proximal end of the first passageway, wherein the first passageway extends to a distal end of the elongated member; a second passageway comprising a generally circular cross-sectional area, the second passageway comprising a second diameter and a second length; and a detector positioned at least partially within and along a distal end of the second passageway such that the detector is positioned at least partially within the elongated member; wherein the first passageway and the second passageway are fluidly separate from each other and are located along different longitudinal axes of the elongated member; and wherein the first diameter is larger than the second diameter, and the first and second passageways are adjacent each other for at least a portion of the elongated member. - View Dependent Claims (7, 8, 9, 10, 17)

11. An elongated member comprising:
-
a valve apparatus; a first passageway extending along a single longitudinal axis from a first proximal end to a first distal end of the elongated member, the first proximal end configured to couple to the valve apparatus, wherein the valve apparatus is configured to seal around a device that is inserted through the valve apparatus and into the first passageway, wherein the first passageway comprises a first diameter and a first length; wherein the valve apparatus is configured to allow other devices to be introduced through the first passageway while preventing fluid from flowing out of the first proximal end of the first passageway; a detector positioned at least partially within and along a distal end of the elongated member; and a wire positioned within a second passage located through a wall of the elongated member, the wire being coupled to the detector, wherein the first passageway is fluidly separate from and located along a different longitudinal axis than the second passage; wherein the detector is configured to monitor a physiologic or biochemical property. - View Dependent Claims (12, 13, 14, 15, 18)
