Abstract

The various embodiments disclosed herein relate to procedural space maintenance devices, medical device positioning devices, and devices that provide both procedural space maintenance and device positioning. Further embodiments relate to medical device insertion and/or retraction devices.

Claims

1. A body cavity spatial support device, the device comprising:

(a) a first inflatable body configured to be disposed within a cavity of a patient'"'"'s body; and

(b) a first inflation mechanism operably coupled to the first inflatable body.

2. The device of claim 1, wherein the first inflatable body is inflatable into an expanded configuration.

3. The device of claim 2, wherein the expanded configuration comprises a generally cylindrical shape.

4. The device of claim 2, wherein the expanded configuration comprises a generally donut-like shape.

5. The device of claim 1, further comprising a second inflatable body configured to be disposed within the cavity of the patient'"'"'s body.

6. The device of claim 5, wherein the first inflation mechanism is further operably coupled to the second inflatable body.

7. The device of claim 5, further comprising a second inflation mechanism operably coupled to the second inflatable body.

8. The device of claim 1, wherein the first inflation mechanism is operably coupled to the first inflatable body through a port, incision, or natural orifice of the patient.

9. A collapsible body cavity spatial support device, the device comprising:

(a) a first link;

(b) a second link hingedly coupled to the first link; and

(c) a third link hingedly coupled to the second link,

wherein the support device is configured to have a collapsed configuration and a deployed configuration.

10. The device of claim 9, further comprising at least five additional links, wherein each of the five additional links is hingedly coupled to at least one of the first, second, third, or additional links.

11. The device of claim 9, the deployed configuration defining a procedural space.

12. A delivery or removal device, comprising:

(a) a tubular body;

(b) a device lumen defined by the tubular body;

(c) a wire lumen defined by the tubular body; and

(d) a wire disposed through the device lumen and the wire lumen.

13. The device of claim 12, wherein the device lumen further comprises a proximal device opening at a proximal end of the tubular body and a distal device opening at a distal end of the tubular body.

14. The device of claim 12, wherein the wire lumen further comprises a proximal wire opening at a proximal end of the tubular body and a distal wire opening at a distal end of the tubular body.

15. The device of claim 12, wherein the wire comprises an attachment component configured to be attachable to a medical device.

16. The device of claim 15, wherein the attachment component is a ball.

17. The device of claim 12, wherein the tubular body comprises protrusion at a distal end of the tubular body, wherein the protrusion further defines the wire lumen.

18. The device of claim 17, wherein the protrusion is a deployable protrusion, the deployable protrusion comprising:

(a) a pivotal connection coupling the deployable protrusion to the distal end of the tubular body;

(b) a releasable retention component configured to retain the deployable protrusion in an undeployed position; and

(c) a spring operably coupled to the deployable protrusion, the spring configured to urge the deployable protrusion toward a deployed position.

19. The device of claim 17, wherein the protrusion further comprises a device receiving component configured to receive a medical device.

20. The device claim of 19, wherein the device receiving component comprises at least one magnet configured to magnetically couple to the medical device, whereby the medical device releasably couples to the device receiving component.
