Abstract

Devices, systems, and methods for treating wounds in endoluminal spaces of a patient are disclosed. A device may include an elongate tube defining a proximal end, a distal end, and a lumen, an expandable component adjustably positioned at the distal end of the elongate tube, and a tether coupled to the expandable component and extending proximal from the expandable component through the lumen to a location exterior of the elongate tube. The expandable component may be adjustable between a delivery position within the elongate tube and a fully deployed position at least partially exterior of the elongate tube. The expandable member may be absorbent. A proximal end of the elongate tube may couple to a vacuum source to apply a negative pressure at or proximate the expandable component. An inner member may extend through the elongate tube and be configured to adjustably engage the expandable component.

Claims (15)

  1. 1. A device for treating a wound in an endoluminal space of a patient, the device comprising: an elongate tube defining a proximal end, a distal end, and a lumen; an expandable component adjustably positioned at the distal end of the elongate tube between a delivery position within the elongate tube and a fully deployed position at least partially exterior of the elongate tube, wherein the expandable component is absorbent; and a tether coupled to the expandable component and extending proximally from the expandable component through the lumen to a location exterior of the elongate tube.
  2. 2. The device of claim 1, wherein the expandable component is adjustable to a partially deployed position having a desired volume between a first volume when the expandable component is in the delivery position and a second volume when the expandable component is in the fully deployed position.
  3. 3. The device of claim 1 or 2, wherein the elongate tube is an elongate outer tube and the device further comprises: an elongate inner member configured to extend into the lumen of the elongate outer tube and having a proximal end exterior of the elongate outer tube.
  4. 4. The device of claim 3, wherein the elongate inner member is configured to engage a proximal portion of the expandable component to adjust a volume of the expandable component deployed from the distal end of the elongate outer tube.
  5. 5. The device of claim 3 or 4, wherein the elongate inner member is an elongate inner tube defining a lumen and the tether extends through the lumen of the elongate inner tube to a location exterior of the elongate inner tube.
  6. 6. The device of any one of claims 1-5, wherein a distal end of the tether is coupled to the expandable component at a location of the expandable component distal of the distal end of the elongate tube when the expandable component is in the fully deployed position.
  7. 7. The device of any one of claims 1-6, wherein the expandable component is configured to evert as it transitions between the delivery position and the fully deployed position.
  8. 8. The device of any one of claims 1-7, wherein the expandable component includes a stem portion and a cap portion and the elongate tube is configured to extend between the stem portion and the cap portion of the expandable component when the expandable component is in the fully deployed position.
  9. 9. The device of any one of claims 1-8, further comprising: a lubricious layer at a location of an outer surface of the expandable component configured to contact the distal end of the elongate tube when the expandable component adjusts between the delivery position and the fully deployed position.
  10. 10. The device of any one of claims 1-9, further comprising: one or more cavities within the expandable component.
  11. 11. The device of any one of claims 1-10, wherein the expandable component is a sponge.
  12. 12. The device of any one of claims 1-11, wherein the expandable component is configured to be wrung-out when it is positioned within the elongate tube.
  13. 13. A system for treating a wound, the system comprising: a vacuum source; an elongate tube defining a lumen; and an expandable component configured to have a first volume associated with a delivery configuration of the expandable component and a second volume associated with a fully deployed configuration of the expandable component, the expandable component is absorbent, and wherein the expandable component is configured to change volume as the expandable component transitions between the delivery configuration and the fully deployed configuration, and wherein the vacuum source is in fluid communication with the lumen and the expandable component when the expandable component is in the delivery configuration, the fully deployed configuration, and transitional configurations between the delivery configuration and the fully deployed configuration.
  14. 14. The system of claim 13, further comprising: a tether coupled to the expandable component and extending proximally from the expandable component through the lumen to a location exterior of the elongate tube.
  15. 15. The system of claim 13 or 14, wherein the elongate tube is an elongate outer tube and the system further comprises: an elongate inner member configured to extend into the lumen of the elongate outer tube and engage a proximal portion of the expandable component to adjust the expandable component from the delivery configuration to an at least partially deployed configuration.

Description

DRAINAGE DEVICES AND SYSTEMS CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Patent Application Serial No. 63/517,657, filed August 4, 2023, which is incorporated herein by reference. TECHNICAL FIELD [0002] The present disclosure pertains generally, but not by way of limitation, to drainage devices, systems, and methods of treatment. More particularly, the present disclosure relates to a device or system for use in providing vacuum wound therapy to a wound of a patient. BACKGROUND [0003] A wide variety of intracorporeal and extracorporeal medical devices and systems have been developed for medical use, for example, for endoscopic procedures. Some of these devices and systems include guidewires, catheters, catheter systems, endoscopic instruments, wound therapy systems, vacuum therapy systems, and the like. These devices and systems are manufactured by any one of a variety of different manufacturing methods and may be used according to any one of a variety of methods. Of the known medical devices, systems, and methods, each has certain advantages and disadvantages. There is an ongoing need to provide alternative medical devices and systems as well as alternative methods for manufacturing and using medical devices and systems. BRIEF SUMMARY [0004] This disclosure provides design, material, manufacturing method, and use alternatives for medical devices.

[0006] Additionally or alternatively to any of the examples above, the expandable component may be adjustable to a partially deployed position having a desired volume between a first volume when the expandable component is in the delivery position and a second volume when the expandable component is in the fully deployed position. [0007] Additionally or alternatively to any of the examples above, the elongate tube may be an elongate outer tube and the device may further comprise an elongate inner member configured to extend into the lumen of the elongate outer tube and having a proximal end exterior of the elongate outer tube. [0008] Additionally or alternatively to any of the examples above, the elongate inner member may be configured to engage a proximal portion of the expandable component to adjust a volume of the expandable component deployed from the distal end of the elongate outer tube. [0009] Additionally or alternatively to any of the examples above, the elongate inner member may be an elongate inner tube defining a lumen and the tether may extend through the lumen of the elongate inner tube to a location exterior of the elongate inner tube. [0010] Additionally or alternatively to any of the examples above, a distal end of the tether is coupled to the expandable component at a location of the expandable component distal of the distal end of the elongate tube when the expandable component is in the fully deployed position. [0011] Additionally or alternatively to any of the examples above, the expandable component may be configured to evert as it transitions between the delivery position and the fully deployed position.
