Abstract

A medical device introduction system and method can include a medical introducer, a separate imaging device, and/or a separate working channel device, each of which may be movable independent of the other. The medical introducer can include a handle and an elongate introducer tube extending from the handle and having a plurality of lumens, and may be inserted into an interior body region of a patient. The separate imaging device may be inserted through the handle and positioned in one of lumens. The separate working channel device can include an elongate working channel tube and a position controller. The working channel tube can include at least one lumen defining a working channel. The position controller can be configured to control positioning of the working channel tube. The working channel device may be removably connected to the handle and positioned in another lumen. Associated with the medical device may be a slider and a rail that stabilizes a medical device and prevents it from turning allowing medical personnel that previously had to hold the medical device to be free to be able to perform other tasks. The medical device may also possess a bent working channel device that provides easier access to orifices or other body parts that are in an orientation that is not straight (i.e., in an orientation that does not require a bend in the working channel device). The medical device may also have sheaths associated with it that causes a bend in the working channel device that also allows easier access to orifices or other body parts that are not straight

Claims

1. A medical device introduction system, comprising:

a medical introducer comprising a handle and an elongate introducer tube extending therefrom and having a plurality of lumens extending

longitudinally therein, the medical introducer insertable into an interior body region of a patient;

a separate imaging device insertable through the handle and positionable in a predetermined one of the plurality of lumens, the imaging device having an interface with the handle such that each of the imaging device and the medical introducer is movable independent of the other; and

a separate working channel device comprising an elongate working channel tube having at least one lumen extending the length thereof defining a working channel and a position controller for controlling the position of the working channel tube, the working channel device removably connectable to the handle and positionable in another predetermined one of the plurality of lumens such that each of the medical introducer, the imaging device, and the working channel device is movable independent of the other;

wherein the position controller further comprises a circular, lower housing having an upwardly extending hollow hub and a cooperating circular, upper housing having a downwardly extending rotor rotatingly seated inside the hollow hub,

wherein the position controller further comprises an automatic braking mechanism comprising a soft material on the outer surface of at least one of the upper housing rotor and the lower housing hub so as to provide sufficient friction to hold the upper housing in position relative to the lower housing when released by a user.

2. The medical introducer device of claim 1, further comprising at least one seal, the seal being of a type and situated in a direction that allows the flow of fluid in one direction but not in the other direction in the medical introducer device.

3. The medical introducer device of claim 1, wherein at least one of the plurality of lumens comprises at least one compound-curved tip.

4. The medical introducer device of claim 3, further comprising more than one compound curved tip.

5. The medical introducer device of claim 3, wherein the at least one compound-curved tip allows the passage of one or more of the imaging device and/or the working channel device is able to pass through an interior of the at least one compound-curved tip.

6. A medical introducer device, comprising:

a handle comprising an oval-shaped ring of material having an open interior, a proximal end, and a distal end;

an elongate introducer tube extending from the distal end of the handle and having a plurality of lumens extending longitudinally therein; and

a separate working channel device comprising an elongate working channel tube having at least one lumen extending the length thereof defining a working channel and a position controller for controlling the position of the working channel tube;

the proximal end of the handle configured to receive at least one fluid tube and an imaging device therethrough; and

the distal end of the handle adapted to connect to the introducer tube, wherein the device is insertable into an interior body region of a patient

wherein the position controller further comprises a circular, lower housing having an upwardly extending hollow hub and a cooperating circular, upper housing having a downwardly extending rotor rotatingly seated inside the hollow hub,

wherein the position controller further comprises an automatic braking mechanism comprising a soft material on the outer surface of at least one of the upper housing rotor and the lower housing hub so as to provide sufficient friction to hold the upper housing in position relative to the lower housing when released by a user.
