Kit for washing an intestinal anastomosis in situ
A kit including a device for intestinal anastomosis enema in situ, and an anastomosis protection device comprising a flexible external sheath connected to a stent located downstream of the sheath and designed to be anchored upstream of the anastomosis. The enema device has: a perforated, tubular element of annular shape that can distribute an enema composition, upstream of the anastomosis, a supply tube one end of which emerges in the tubular element and one end of which is open to injection means designed to deliver the composition into said tubular element, holding means for the tubular element upstream of the anastomosis.
1. A kit for performing an intestinal anastomosis enema in situ in an intestine having an anastomosis, the kit comprising:
an anchor configured to be anchored within the intestine upstream of the anastomosis;
a sheath coupled to the anchor, the sheath configured to extend downstream from the anchor and across the anastomosis to thereby protect the anastomosis; and
an enema device comprising a perforated, annularly shaped tube configured to distribute an enema composition, the perforated, annularly shaped tube configured to be positioned in the intestine upstream of the anastomosis, the enema device further comprising a supply tube having a first end coupled to the perforated, annularly shaped tube and a second end configured to receive an injection of the enema composition for delivery into the perforated, annularly shaped tube upstream of the anastomosis such that the enema composition flows downstream to the anastomosis.
2. The kit of claim 1 , wherein the perforated, annularly shaped tube comprises loops, tabs, or hooks positioned on the perforated, annularly shaped tube.
3. The kit according to of claim 1 , wherein the anchor comprises a stent configured to contact the intestine's wall for anchoring.
4. The kit of claim 1 , wherein the supply tube of the enema device has an inner diameter between 1 and 8 mm.
5. The kit of claim 1 , wherein the perforated, annularly shaped tube of the enema device comprises multiple perforations regularly spaced around a circumference of the perforated, annularly shaped tube.
6. The kit of claim 1 , wherein the enema device is formed of biocompatible material.
7. The kit of claim 1 , wherein the second end of the supply tube is configured to be coupled to a syringe or a pump for delivering the enema composition.
8. The kit of claim 1 , wherein the kit comprises the enema composition.
9. The kit according to of claim 1 , wherein the perforated, annularly shaped tube is coupled to the anchor.
10. The kit of claim 1 , wherein the perforated, annularly shaped tube is positioned at a downstream end of the anchor.
11. The kit of claim 1 , wherein the anchor comprises a vacuum chamber configured to maintain a vacuum for anchoring within the intestine.
12. The kit of claim 11 , wherein the supply tube is separate from a suction tube configured to apply suction to the vacuum chamber.
13. The kit of claim 1 , wherein the sheath is configured to divert fecal matter to the anus such that the fecal matter does not contact the intestine at the anastomosis to thereby protect the anastomosis.
14. The kit of claim 1 , wherein the enema device is configured to deliver the enema composition over an enema period between 1 day and 3 weeks.
15. A method for performing an intestinal anastomosis enema in situ in an intestine having an anastomosis, the method comprising:
anchoring an anchor within the intestine upstream of the anastomosis, the anchor coupled to a sheath that extends downstream from the anchor across the anastomosis to thereby protect the anastomosis; and
delivering an enema composition from an enema device comprising a perforated, annularly shaped tube positioned in the intestine upstream of the anastomosis via a supply tube coupled to the perforated, annularly shaped tube such that the enema composition flows downstream to the anastomosis.
16. The method of claim 15 , wherein the perforated, annularly shaped tube is coupled to a downstream end of the anchor.
17. The method of claim 15 , wherein delivering the enema composition comprises injecting the enema composition into an externally-positioned end of the supply tube.
18. The method of claim 15 , wherein anchoring the anchor comprises applying suction to a vacuum chamber of the anchor to suck the intestine against the anchor.
19. The method of claim 15 , further comprising diverting, via the sheath, fecal matter to the anus such that the fecal matter does not contact the intestine at the anastomosis to thereby protect the anastomosis.
20. The method of claim 15 , wherein delivering the enema composition comprises delivering the enema composition over an enema period between 1 day and 3 weeks.
