Abstract

Apparatus and methods for use in an image-guided interventional procedure are described herein. In one embodiment, an apparatus includes a base configured to be releasably coupled to a patient'"'"'s skin. A support portion extends from the base at an angle transverse to a longitudinal axis defined by the base. The support portion has a first end portion and a second end portion. The first end portion is disposed adjacent the base. A holder portion extends from the second end portion of the support portion. The holder portion defines an opening and is configured to be moved between a first configuration in which the opening defined by the holder portion has a first size and is configured to movably receive an interventional tool therethrough, and a second configuration in which the opening defined by the holder portion has a second size different than the first size.

Claims

1. An apparatus, comprising:

a base configured to be releasably coupled to a patient'"'"'s skin, the base defining a longitudinal axis;

a support portion extending from the base at an angle transverse to the longitudinal axis defined by the base, the support portion having a first end portion and a second end portion, the first end portion disposed adjacent the base;

a holder portion extending from the second end portion of the support portion in a first direction, the holder portion defining an opening configured to receive an interventional tool therethrough;

a first rib member extending from the support portion in a second direction opposite the first direction; and

a second rib member extending from the support portion in the second direction, the first rib member and the second rib member each being pivotally movable relative to the support portion from a first configuration in which the first rib member and the second rib member are substantially parallel to each other and the opening defined by the holder portion has a first size, and a second configuration in which the first rib member and the second rib member are each pivoted relative to the support portion and toward each other and the opening defined by the holder portion has a second size greater than the first size.

2. The apparatus of claim 1, wherein when the first rib member and the second rib member are in the first configuration, the holder portion is configured to releasably maintain the interventional tool within the opening.

3. The apparatus of claim 1, wherein the holder portion includes a first holder arm and a second holder arm that collectively define the opening.

4. The apparatus of claim 1, further comprising:

an adjustment mechanism coupled to the holder portion, the adjustment mechanism configured to be moved between a first configuration in which an opening defined by the adjustment mechanism has a first size and a second configuration in which the opening of the adjustment mechanism has a second size different than the first size.

5. The apparatus of claim 1, wherein the first size of the opening is a first diameter of the opening, the second size of the opening is a second diameter of the opening, the holder portion includes an adjustment portion configured to selectively adjust the diameter of the opening defined by the holder portion between a plurality of diameters, the plurality of diameters including the first diameter and the second diameter.

6. The apparatus of claim 1, wherein the base is configured to be adhesively coupled to the patient'"'"'s skin.

7. The apparatus of claim 1, wherein the base is configured to be coupled to the patient'"'"'s skin using a suction force.

8. The apparatus of claim 1, wherein the interventional tool is a needle.

9. An apparatus, comprising:

a base configured to be releasably coupled to a patient'"'"'s skin;

an elongate support member coupled to the base, the elongate support member having a first end portion and a second end portion, the first end portion being coupled to the base;

a holder member releasably couplable to the second end portion of the elongate support member, the tool guide configured to guide an interventional tool during an image guided interventional procedure at a predetermined angle relative to the patient'"'"'s body,

the holder member configured to be coupled to a tool guide of an image guided positioning device during an image guided interventional procedure, the tool guide configured to guide an interventional tool during an image guided interventional procedure at a predetermined angle relative to the patient'"'"'s body,

the holder member configured to be movable from a first position in which a first coupling portion of the holder member is coupled to the tool guide and the holder member is not coupled to the second end portion of the elongate support member, and a second position in which a second coupling portion of the holder member is coupled to a clamp device coupled to the second end portion of the elongate support member and configured to stabilize the interventional tool at the predetermined angle relative to the patient'"'"'s body.

10. The apparatus of claim 9, wherein the clamp device is pivotally coupled to the second end portion of the elongate support member, the holder member being releasably couplable to the clamp device, the clamp device and the holder member collectively being pivotally movable relative to the support member when the holder member is coupled to the clamp device.

11. The apparatus of claim 9, wherein the first end portion of the support member is pivotally coupled to the base.

12. The apparatus of claim 9, wherein the base is configured to be adhesively coupled to the patient'"'"'s skin.

13. The apparatus of claim 9, wherein the base is configured to be coupled to the patient'"'"'s skin with a suction force.

14. The apparatus of claim 9, wherein the interventional tool is a needle.

20. The apparatus of claim 9, wherein the tool guide is configured to guide an interventional tool during an image guided interventional procedure at a predetermined height relative to the patient'"'"'s body.

15. An apparatus, comprising:

a base configured to be releasably coupled to a patient'"'"'s skin;

an elongate support member coupled to the base, the elongate support member having a first end portion and a second end portion, the first end portion being coupled to the base;

a holder member releasably couplable to the second end portion of the elongate support member; and

an image-guided positioning device disposed adjacent the patient, the image-guided positioning device including a tool guide, the tool guide configured to guide an interventional tool during an image guided interventional procedure at a predetermined angle relative to the patient'"'"'s body,

the holder member configured to be coupled to the tool guide of the image guided positioning device during an image guided interventional procedure,

the holder member configured to be movable from a first position in which the holder member is coupled to the tool guide and is not coupled to the second end portion of the elongate support member and a second position in which the holder member is coupled to a clamp device coupled to the second end portion of the elongate support member and configured to stabilize the interventional tool at the predetermined angle relative to the patient'"'"'s body.

16. The apparatus of claim 15, wherein the base is configured to be adhesively coupled to the patient'"'"'s skin.

17. The apparatus of claim 15, wherein the base is configured to be coupled to the patient'"'"'s skin with a suction force.

18. The apparatus of claim 15,

wherein the clamp device is pivotally coupled to the second end portion of the elongate support member, the holder member being releasably couplable to the clamp device.
