Abstract

A medical device may include a luminal body defining a working channel extending between a proximal end of the luminal body and a distal end of the luminal body. The device may also include a carrier defining a pusher thereon. The carrier may be configured to transition between a first state and a second state. In the first state, a distal portion of the carrier may extend within the working channel along a central longitudinal axis thereof. In the second state, the distal portion of the carrier may extend distally of the luminal body. The device may also include a plurality of anchors which may be disposed about the carrier. Also, at least a distal-most anchor of the plurality of anchors may define a surface configured to cooperate with the pusher and further defines a curved wall configured to cooperate with the pusher to rotate the plurality of anchors.

First claim

What is claimed is:

1. A medical device, comprising:
a luminal body defining a working channel extending between a proximal end of the luminal body and a distal end of the luminal body;
a rotatable member disposed within the working channel;
a carrier defining a pusher thereon, wherein the carrier is configured to transition between a first state and a second state, when in the first state, a distal portion of the carrier is disposed within the working channel along a central longitudinal axis of the working channel, and when in the second state, the distal portion of the carrier extends distally of the luminal body and the rotatable member at an angle with respect to the longitudinal axis; and
a plurality of anchors, each anchor of the plurality of anchors disposed about the carrier, wherein at least a distal-most anchor of the plurality of anchors defines a surface configured to cooperate with the pusher, and wherein at least the distal-most anchor of the plurality of anchors further defines a curved wall configured to cooperate with the pusher to rotate the plurality of anchors.

2. The medical device of claim 1 , wherein the carrier is comprised of a shape memory material.

3. The medical device of claim 1 , wherein the carrier has a distal tip configured to pierce tissue.

4. The medical device of claim 3 , wherein the distal tip of the carrier is configured to be passed through a central lumen of each of the plurality of anchors.

5. The medical device of claim 1 , wherein the plurality of anchors comprises at least the distal most anchor and a travel anchor, wherein the travel anchor is coupled to the distal most anchor via at least one suture member.

6. The medical device of claim 1 , wherein each anchor of the plurality of anchors defines a recess configured to cooperate with the pusher, and wherein each anchor of the plurality of anchors defines a curved wall configured to cooperate with the pusher to rotate the plurality of anchors.

7. The medical device of claim 6 , wherein each anchor of the plurality of anchors is coupled to an adjacent anchor of the plurality of anchors via at least one suture member.

8. The medical device of claim 1 , further comprising: a handle coupled to the proximal end of the luminal body and including an actuator operably coupled with the carrier to move the carrier between the first and second states.

9. The medical device of claim 8 , wherein the actuator is operably coupled to the carrier via a cam follower mechanism.

10. The medical device of claim 1 , wherein each anchor of the plurality of anchors define a proximal extension and a distal recess.

11. The medical device of claim 10 , wherein the proximal extension of each anchor of the plurality of anchors is configured to be matingly received within the distal recess of an adjacent anchor of the plurality of anchors.

12. The medical device of claim 10 , wherein the proximal extension and distal recess of at least some of the plurality of anchors are radially offset from one another while the proximal extension and distal recess of the remaining anchors of the plurality of anchors are aligned along a common axis.

13. A medical device, comprising:
a luminal body defining a working channel extending between a proximal end of the luminal body and a distal end of the luminal body;
a revolving member defining a plurality of chambers therein, the revolving member being rotatably coupled to the distal end of the luminal body;
a carrier configured to transition between a first state and a second state, wherein:
when in the first state, a distal portion of the carrier is disposed within the working channel along a central longitudinal axis of the working channel, and
when in the second state, the distal portion of the carrier is configured to extend distally of the luminal body and the revolving member in a curved configuration; and

a plurality of anchors, at least one anchor of the plurality of anchors being positioned within each chamber of the plurality of chambers; and
a handle assembly including an actuator operably coupled with the carrier and an energy transmission element operably coupled with the revolving member, wherein linear movement of the carrier may result in rotational movement of the revolving member via the energy transmission element.

14. The medical device of claim 13 , wherein the carrier is comprised of a shape memory material.

15. The medical device of claim 13 , wherein the revolving member defines six chambers.
