Abstract

A medical device having a member with a lumen extending from a proximal end to a distal end of the member is disclosed. The lumen has a device portion defined by at least one curved walled portion and at least one anchoring portion. An endoscopic device, such as a needle, is attached to an actuator inserted into the device portion of the lumen. A housing or stop is inserted into the distal end of the lumen.

Claims

1. A medical device for performing endoscopic procedures, comprising:

a member having at least one lumen extending from a proximal end to a distal end, wherein the at least one lumen has both a device portion and at least one anchoring portion, wherein the device portion is defined by at least one curved walled portion, wherein the device portion and the at least one anchoring portion are disposed parallel along a length of the member, and the at least one curved walled portion defines at least a portion of a perimeter of the device portion from a center point thereof;

an actuator having a proximal end and a distal end disposed within the device portion of the at least one lumen;

an endoscopic device attached to the distal end of the actuator; and

a housing having a base and at least one leg, wherein the at least one leg is fixed to the at least one anchoring portion of the at least one lumen, and the base has a hole sized to permit deployment of the endoscopic device therethrough;

wherein the at least one lumen is operably configured to reduce side-to-side motion of the actuator, and to reduce friction between the endoscopic device and the member, by;

i) having the at least one curved wall portion adjacent to the actuator from the proximal end to the distal end of the member; and

ii) fixing the at least one leg to the at least one anchoring portion at a location outside of the perimeter of the device portion.

2. The medical device of claim 1 further comprising at least one connection between the device portion and the at least one anchoring portion.

3. The medical device of claim 2, wherein two elongated ridges define the at least one connection between the device portion and the at least one anchoring portion.

4. The medical device of claim 1, wherein the device portion is defined by two curved walled portions defining an inner diameter at least as large as an outer diameter of the actuator.

5. The medical device of claim 1, wherein the at least one leg is sized to engage the at least one anchoring portion of the at least one lumen to create a press fit when the at least one leg is inserted into a distal end of the at least one anchoring portion.

6. The medical device of claim 5, wherein the at least one leg further comprises at least one ribbed section that creates a friction surface against the at least one anchoring portion of the at least one lumen.

7. The medical device of claim 5, wherein an adhesive holds the at least one leg of the housing in the at least one anchoring portion of the at least one lumen.

8. The medical device of claim 1, wherein the base further comprises a conical concave surface for aligning the endoscopic device with the hole as the endoscopic device is deployed.

9. The medical device of claim 8, wherein the endoscopic device further comprises a hub sized to interfere with the conical concave surface and prevent the endoscopic device from exiting the distal end of the at least one lumen.

10. The medical device of claim 1, wherein the at least one leg further comprises an inner surface that defines a travel path of the endoscopic device and prevents the endoscopic device from puncturing the member.

11. The medical device of claim 1, wherein a outer surface of the housing comprises a non-conductive material.

12. The medical device of claim 1, wherein the endoscopic device is a needle and the actuator is a tube.

13. A medical device for performing endoscopic procedures, comprising:

a member having a first lumen and a second lumen, each lumen having a proximal end and a distal end, wherein the first lumen has both a device portion and at least one anchoring portion, wherein the device portion is defined by at least one curved walled, wherein the device portion and the at least one anchoring portion are disposed parallel along a length of the member;

a first actuator and a second actuator, each actuator having a proximal end and a distal end, wherein the first actuator is disposed within the device portion of the first lumen and the second actuator is disposed within the second lumen;

a first endoscopic device and a second endoscopic device, wherein the first endoscopic device is attached to the distal end of the first actuator and the second endoscopic device is attached to the distal end of the second actuator; and

a housing having a base and at least one leg, wherein the at least one leg is fixed to the at least one anchoring portion at a location radially beyond the curved wall portion relative to a centerpoint of the device portion, and the base has a hole sized to permit deployment of the first endoscopic device therethrough.

14. The medical device of claim 13, wherein the first endoscopic device includes a needle and the second endoscopic device includes a snare.

15. A medical device for performing endoscopic procedures, comprising:

a member having a lumen extending from a proximal end to a distal end, wherein the lumen has a device portion, a first anchoring portion, and a second anchoring portion disposed remotely from the first anchoring portion, wherein the device portion, the first anchoring portion and the second anchoring portion are disposed parallel along a length of the member, and the device portion is defined by two walled portions defining an inner channel;

an actuator tube having a proximal end and a distal end, the tube disposed within the device portion of the lumen;

a needle attached to the distal end of the actuator tube; and

a housing having a base, a first leg, and a second leg, wherein the first leg is fixed relative to the first anchoring portion and the second leg is fixed relative to the second anchoring portion, wherein the base has a hole sized to permit deployment of the needle and a conical concave surface for aligning the needle with the hole as the needle is deployed, and the first leg and the second leg are disposed radially beyond the inner channel defined by the two walled portions relative to a centerpoint of the device portion.

16. The medical device of claim 15, wherein the first leg and the second leg each comprise an inner surface, wherein the inner surface of the first leg and the inner surface of the second leg form a partial-walled cylinder defining a travel path of the needle and actuator tube.

17. A medical device for performing endoscopic procedures, comprising:

a catheter having a first lumen and a second lumen, each lumen having a proximal end and a distal end, wherein the first lumen defines three contiguous and parallel portions including a device portion, a first anchoring portion, and a second anchoring portion disposed remotely from the first anchoring portion, wherein the device portion is defined by two opposing curved walled portions partially defining a cylinder;

an actuator tube having a proximal end and a distal end disposed within the device portion of the first lumen;

a cable having a proximal end and a distal end disposed within the second lumen;

a needle attached to the distal end of the actuator tube;

a snare assembly attached to the distal end of the cable; and

a needle housing having a base, a first leg extending from the base, and a second leg extending from the base, wherein the first leg is fixed within a distal end of the first anchoring portion and the second leg is fixed within a distal end of the second anchoring portion, wherein the base has a hole sized to permit deployment of the needle therethrough and a conical concave surface on a proximal side thereof, and the first leg and the second leg are each disposed entirely outside of the cylinder partially defined by the two curved walled portions.
