摘要:
An ERCP catheter having a removable handle for a lithotriptor compatible basket is disclosed. The removable handle allows the catheter and handle assembly to be removed, leaving the basket in place within the duct and facilitates the use of a lithotriptor for mechanically crushing stone captured in the basket.
摘要:
A handle for a medical device is provided. The handle includes an inner handle member and first and second outer handle members slideably disposed on the inner handle member. An elongate sheath is attached to the inner handle member and extends axially beyond a distal end of the inner handle member and a stylet is attached to one of the outer handle members and disposed in a lumen of the sheath. Slideable movement of the outer handle members relative to the inner handle members controls relative positioning of various components of the handle.

A steerable wire-guide comprises an elongate member having a longitudinal axis. The elongate member comprises a leading portion and a body portion. The leading portion comprises a loop and the body portion comprises a first wire and a second wire. The first and second wires are movable relative to each other such that relative movement of the first wire with respect to the second wire directs the leading portion in a first direction, which is at an angle relative to the longitudinal axis, and relative movement of the second wire with respect to the first wire directs the leading portion in a second direction different from the first direction.
摘要:
A wire guide has first and second portions with first and second diameters, respectively. A resilient loop positions a distal end of the wire guide adjacent another section of the wire guide. A closure member comprising at least one attachment tab maintains the distal end in a fixed position relative to the remainder of the wire guide. A covering may be positioned around one or more parts of the wire guide.
摘要:
An elongate medical device configured for navigation through a lumen is provided. The device includes an elongate shaft having a proximal portion and a distal portion. The distal portion includes a first interlocking connector. The device further includes a loop portion operably connected to the distal portion. The loop portion includes a second interlocking connector configured for connecting to the first interlocking connector. A medical system is also provided including a catheter and a wire guide. A method of making a wire guide is provided.
摘要:
A wire guide holder having a body for securing an elongate medical wire or tube, such as a wire guide or catheter. The body is adapted to be attached to a scope or a bite block. The body can be provided with protrusions and/or grooves for holding a wire guide. The wire guide holder may be affixed to the medical scope by clamping. The wire guide holder can also be provided with a seal.
摘要:
A multi-dimensional loop tip structure is provided that is capable of navigating through a tortuous body lumen. The multi-dimensional loop tip structure includes two or more loops or partial loops at the distal end of the structure. The structure may alternatively include three or more legs at the distal end of the structure. The loops or legs allow the structure to continuously realign itself to the center of a body lumen that it is being navigated through when encountering impediments therein.

摘要:
A device and method for accessing the interior of a cavity of a patient is described. The transmural access system includes an overtube for use with an endoscope, a safety trocar, suture anchors, and a suture exchanger. The overtube is deployed in conjunction with an endoscope through a selected body passageway of a patient to locate a sight for an access portal. The distal end of the multi-lumen overtube is secured to an interior body wall of the selected access portal. A safety trocar is advanced through the main lumen of the overtube to form the access portal to the body cavity. Upon completion of the desired medical procedure, the access portal can be closed by deploying a suture exchanger.
