Abstract

This present disclosure provides devices, systems, and methods relating to the management of a subject's medical needs involving safely accessing a body cavity. In particular, the present disclosure is directed to body cavity conduit devices and systems that facilitate repeated access to a subject's body cavity for removing fluid or performing a procedure in a manner that provides enhanced comfort, safety, and efficacy.

First claim

1 . A body cavity conduit device comprising:
a proximal end comprising a low-profile first opening positioned external to a subject's body; a distal end comprising a second opening positioned within a body cavity of the subject; and a stem comprising a channel that connects the proximal end and the distal end; wherein at least one of the proximal end and/or the distal end comprises a self-sealing valve.

2 . The device of claim 1 , wherein the proximal end comprises a self-sealing valve and wherein the distal end comprises a self-sealing valve.

3 . The device of claim 1 , wherein the self-sealing valve is configured to prevent fluid flow through the stem channel.

4 . The device of claim 1 , wherein the self-sealing valve comprises a perforation for insertion of an accessory component, wherein the perforation is configured to form a seal around the accessory component when inserted into the stem channel.

5 . The device of claim 1 , wherein the proximal end comprises a cover cap and plug for insertion into the first opening, wherein the plug is configured to form a seal when inserted into the first opening.

6 . The device of claim 1 , wherein the low-profile first opening does not extend outwardly more than 5 cm from the subject's body.

7 . The device of claim 1 , wherein the low-profile first opening extends outwardly from about 1 cm to about 3 cm from the subject's body.

8 . The device of claim 1 , wherein the proximal end further comprises a retention balloon port and a retention balloon valve.

9 . The device of claim 1 , wherein the distal end comprises a retention balloon that is positioned within the subject's body cavity.

10 . The device of claim 1 , wherein the stem comprises a retention balloon channel extending from the retention balloon port to the retention balloon, wherein the retention balloon channel is parallel to the stem channel

11 . The device of claim 9 , wherein the retention balloon is configured to hold from about 2 ml to about 25 ml of a fluid.

12 . The device of claim 1 , wherein the stem is no greater than 30 cm in length.

13 . The device of claim 1 , wherein the stem is from about 1 cm to about 15 cm in length.

14 . The device of claim 1 , wherein the stem is no greater than 35 Fr in diameter.

15 . The device of claim 1 , wherein the stem is from about 10 Fr to about 30 Fr in diameter.

16 . The device of claim 1 , wherein the accessory component comprises at least one of a bladder catheter, a gastrostomy tube, a drainage catheter, an ablation catheter, a catheter for instilling medication or fluid, an endoscope, a needle, and/or a biopsy tool.

17 . The device of claim 1 , wherein the subject's body cavity comprises at least a portion of a bladder cavity, a stomach cavity, an intestinal cavity, a peritoneal cavity, a pleural cavity, a fluid collection cavity, a retroperitoneal cavity, a kidney cavity or a gall bladder.

18 . A kit comprising:
the body cavity conduit device of claim 1 ; and an obturator tool, device, balloon and/or dilator.

19 . The kit of claim 18 , wherein the kit further comprises at least one of the following: a guidewire, a dilator, a stem measuring device, a slip tip syringe, bladder catheter, a gastrostomy tube, a drainage catheter, an ablation catheter, a catheter for instilling medication or fluid, an endoscope, a needle, a biopsy tool, a splitable or separating removable sheath, and a cleaning tool for a channel.

20 . A method for inserting the body cavity conduit device of claim 1 into a body cavity of a subject, the method comprising:
insert an obturator tool, device, balloon, and/or dilator positioned at the distal end of the device over a guidewire and into the subject's body cavity such that the distal end of the device is positioned in the subject's body cavity and the proximal end of the device is positioned external to the subject's body;
inflate the retention balloon with a suitable volume of a fluid to secure placement of the device in the subject; and
remove the obturator and the guidewire.
