Abstract
A device, comprising: a tubular member which is flexible, the tubular member forming a channel when in an open and active configuration and the tubular member narrowed when in a closed and inactive configuration. The device, once expanded into the open and active configuration provides for a channel. The channel provides for a passthrough for medical instruments.
Claims24
A device configurable between a closed configuration and an open configuration to form a passageway for passage of a surgical instrument therethrough, the device comprising:
- a) a tubular member which is flexible, wherein the tubular member is configured to expand from the closed configuration to the open configuration;
- b) a channel formed in the tubular member when in the open configuration which provides the passageway through the tubular member;
- c) one or more wires inside of the tubular member biased toward the open configuration;
- and
- d) one or more biasing devices configured to pass through the one or more wires to restrict the one or more wires in the closed configuration;
- and
- wherein removal of the one or more biasing devices causes the one or more wires to become unrestricted and exert a radially outward force on an interior wall of the tubular member such that the tubular member radially expands from the closed configuration to the open configuration.
A method using a device for providing a passageway into an anatomical orifice, the method comprising:
- a) inserting the device into the anatomical orifice, the device configurable between a closed configuration and an open configuration, wherein the device comprises:
- a tubular member which is flexible, wherein the tubular member is configured to expand from the closed configuration to the open configuration;
- a channel formed in the tubular member when in the open configuration which provides the passageway through the tubular member;
- one or more wires inside of the tubular member biased toward the open configuration;
- and
- one or more biasing devices configured to restrict one or more wires in the closed configuration;
- and
- b) expanding the device by removing one or more biasing devices such that the one or more wires become unrestricted and exert a radially outward force on an interior wall of the tubular member to provide for expansion of the device from the closed configuration to the open configuration thus forming the channel within the tubular member of the device, wherein upon expansion into the open configuration, the device provides the passageway for one or more surgical instruments in the anatomical orifice and causes dilation of the anatomical orifice.
A device configurable between a closed configuration and an open configuration to form a passageway for a surgical instrument, the device comprising:
- a) a tubular member which is flexible, wherein the tubular member is configured to expand from the closed configuration to the open configuration;
- b) a channel formed in the tubular member when in the open configuration which provides the passageway of the tubular member;
- c) one or more wire coils inside of the tubular member, wherein in the closed configuration, each wire coil is in a twisted configuration such that each wire coil has a main coil and a pass-through coil overlapping the main coil;
- d) at least one biasing device configured to apply a compressive force to each wire coil to maintain the twisted configuration of each wire coil such that the tubular member remains in the closed configuration;
- and
- wherein removal of the at least one biasing device causes the one or more wire coils to untwist and move into an untwisted configuration such that the one or more wire coils exert an outward force in a radial direction on an interior wall of the tubular member such that the tubular member expands in the radial direction from the closed configuration to the open configuration.
