Abstract
An essentially hollow device for use in a body opening without limitation to but as an endotracheal tube, a bronchoscope, a vascular or cervical dilator and the like wherein the same has an outer surface that is operable to expand into engagement with the wall of the body opening into which the same is adapted to be inserted.
Claims20
A device for insertion into a body opening comprising a tube-like member longer in length than in cross section having an uninterrupted relatively smooth outer surface yieldable to vary in cross section along substantially its full length,
- a hollow passage extending through the full length of said member,
- means movable in response to a selective operation to vary the cross section of the outer surface of said member along substantially the full length thereof,
- and operable means connected with said movable means to selectively move the same to vary the cross section of said outer surface of said member.
A device for insertion into a body opening as an endotracheal tube and the like comprising a member for removable insertion into a body opening and having an outer surface for expanding toward engagement with and for contraction away from engagement with the body opening and an inner surface defining a passage in said member and that is open at the opposite ends of said member,
- said member including means movable to cause said member to expand and contract at its outer and inner surfaces along substantially the full length thereof and to vary the cross-sectional area of said passage,
- and operable means connected with said movable means to move the same to expand and contract said member.
An elongated substantially tube-like device for insertion into and removal from a body opening having an inner surface defining a passage extending from one end to the other end thereof and adapted to increase and decrease in its cross section at its inner and outer surfaces in a plane substantially perpendicular to the length thereof comprising a plurality of elements movable relative to each other in a direction substantially perpendicular to the length of said device and positioned along substantially the full length of said device and free of interference with said passage,
- means on said device to cause said elements to move relative to each other,
- and said device being an elastomeric member engaging said elements and movable therewith to increase and decrease in cross section in the plane substantially perpendicular to the length of said device in response to the relative movements of said elements.
A device for use in a body opening comprising an elongated member having an essentially smooth uninterrupted outer surface for insertion into a body opening and having an inner surface defining a hollow, unobstructed through passage,
- said member being expandable along substantially its full length in a direction substantially normal to its length and having means operable to cause said outer and inner surfaces and said unobstructed through passage to expand in a direction substantially normal to the length of said member,
- and manual means on said device to operate said operable means.
