Guidewire locking device and method
First Claim
14. A locking device for maintaining a position of a first elongated member relative to a flexible endoscope while a second elongated member is withdrawn from the body lumen, the locking device comprising:
- a mounting mechanism for selectively coupling the locking device to a proximal end of the endoscope;
a head which, when the mounting mechanism is coupled to the endoscope in a predetermined configuration, overlies an opening at the proximal end of the endoscope to a working channel of the endoscope; and
a plurality of locking features extending from the head to immobilize a portion of the first elongated member relative to the endoscope.

Abstract
A locking device for a maintaining an elongated member at a selected place within a body lumen includes a substantially rigid body including an attachment portion adapted to be coupled to a proximal portion of a medical instrument. When in an operative position, the distal portion of the medical instrument is received within the body lumen and a head coupled to the substantially rigid body. The head is configured to overlie an access port of the medical device when the attachment portion is coupled to the proximal portion of the medical device in a predetermined configuration. A plurality of locking features extends from the head to immobilize a section of the elongated member relative to the medical device.

22. A method of performing a medical procedure, comprising the steps of:
-
inserting an endoscope into a body lumen;
inserting a distal end of a first elongated member into the lumen via an access port at a proximal end of the endoscope, so that a proximal portion of the first elongated member extends proximally from the access port; and
immobilizing a portion of the first elongated member relative to the endoscope by engaging a first locking feature of a locking device with the first elongated member. - View Dependent Claims (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 23, 24, 25, 26)

26-1. The method according to claim 23, wherein the locking device comprises a second locking feature, the method further comprising the steps of:
-
immobilizing a portion of a third elongated member relative to the endoscope by engaging a second locking feature with the third elongated member; and
engaging the locking arm with the third elongated member to direct the third elongated member along a second predetermined path from the proximal end of the endoscope to the second locking feature.
