Abstract
Surgical assemblies and related methods are provided for using an actuator to deploy an coupler configured to close a tissue puncture or natural opening in the body, or to create an anastomosis. The surgical method includes deploying first and second anastomotic couplers within a patient to create anastomoses in the body to aid in the treatment of various ailments. The first coupler is deployed to fluidly join a gall bladder and an ileum, and the second coupler is deployed to fluidly join a proximal ileal loop and a distal ileal loop. Fluid can flow between central lumens of the first and second couplers.
Claims17
A surgical method, comprising:
- advancing a first coupler through a small intestine to a region of the small intestine proximate a gallbladder, the first coupler being coupled to a distal end of an elongate shaft;
- piercing the region of the small intestine and the gallbladder using a penetrator advanced through the elongate shaft and the first coupler;
- advancing the first coupler at least partially within the gallbladder;
- deploying, via a rotational force applied to the first coupler, a first distal wing of the first coupler within the gallbladder;
- retracting the elongate shaft to cause the first distal wing to contact an inner surface of the gallbladder;
- deploying, via a rotational force applied to the first coupler, a first proximal wing of the first coupler within the small intestine to removably affix the first coupler to the gallbladder and the small intestine;
- and
- ejecting the first coupler from the distal end of the elongate shaft.

A method, comprising:
- deploying, via an actuator tool having an elongate shaft and a first coupler coupled to a distal end of the elongate shaft, a first distal wing of the first coupler within a gallbladder and first proximal wing of the first coupler within an ileum;
- deploying, via the actuator tool having a second coupler coupled to the distal end, a second distal wing of the second coupler within a first loop of the ileum distal to the deployed first coupler, and a second proximal wing of the second coupler within a second loop of the ileum proximal to the deployed first coupler;
- wherein the first coupler defines a first central lumen configured to fluidly join the gallbladder and the ileum therethrough;
- and
- wherein the second coupler defines a second central lumen configured to fluidly join the first and second loops therethrough.
2 more elements
A method comprising:
- introducing a first coupler into an ileum, the first coupler being attached to an elongate shaft extending distally from an actuator tool, the first coupler and the elongate shaft defining a first central lumen therethrough;
- contacting an outer wall of the ileum adjacent an outer wall of a gallbladder with a distal end of the first coupler;
- extending a first penetrator through the first central lumen to pierce the inner wall of the ileum and the outer wall of the gallbladder;
- advancing the first coupler from the ileum and into the gallbladder;
- deploying, through a first rotational force applied by the actuator tool, a distal wing of the first coupler within the gallbladder;
- retracting the first coupler to contact an inner wall of the gallbladder with the distal wing;
- deploying, through a second rotational force applied by the actuator tool, a proximal wing of the first coupler within the ileum, the gallbladder and the ileum being in fluid communication via the first coupler;
- and
- de-coupling the first coupler from the elongate shaft.
6 more elements
A method, comprising:
- inserting a sheath through an ileum and into a gallbladder;
- advancing an expandable coupler coupled to a distal end of an actuator tool through the sheath and into the gallbladder;
- retracting the sheath from the gallbladder to expose the expandable coupler;
- deploying, through a first rotational force applied by the actuator tool, a distal wing of the expandable coupler within the gallbladder;
- deploying, through a second rotational force applied by the actuator tool, a proximal wing of the expandable coupler within the ileum, the gallbladder and the ileum being in fluid communication via the deployed expandable coupler;
- and
- de-coupling the expandable coupler from the actuator tool.
