Abstract

A marking device may include a body. The body may be configured to transition between a closed configuration and an open configuration. The body may further include two arms. A distal end of each arm may be coupled to a distal end of the body. The marking device may further include a suture coupled to the body. Application of a force on a proximal end of each arm may be configured to cause the body to transition between the closed configuration and the open configuration.

Claims

1. A marking device, comprising:

a body configured to transition between a closed configuration and an open configuration;

two arms, wherein a distal end of each arm is coupled to a distal end of the body; and

a suture coupled to the body,

wherein application of a force on a proximal end of each arm is configured to cause the body to transition between the closed configuration and the open configuration.

2. The marking device of claim 1, wherein the body comprises a clip.

3. The marking device of claim 1, wherein, in the open configuration, the body defines a receiving space.

4. The marking device of claim 3, wherein the receiving space is configured to retain tissue therein.

5. The marking device of claim 1, wherein the body further includes two legs.

6. The marking device of claim 5, wherein a distal end of each leg includes a rounded lip.

7. The marking device of claim 6, wherein the distal end of each arm is received within the rounded lip of a respective leg.

8. The marking device of claim 7, wherein a shape of each distal end of each arm is complementary to a shape of each lip.

9. The marking device of claim 5, wherein in the open configuration, distal ends of each leg are spaced from one another by a first distance, and wherein in the closed configuration, the distal ends of each leg are spaced from one another by a second distance, wherein the first distance is greater than the second distance.

10. The marking device of claim 1, wherein the body comprises at least one of stainless steel, plastic, and Nitinol.

11. The marking device of claim 1, wherein the suture includes a length sufficient to extend externally of a patient when the marking device is internal of a patient.

12. The marking device of claim 1, wherein a handle member is coupled to a proximal end of the suture.

13. A marking system for treating BPH, comprising:

an adjustable ligation member configured to transition between a first collapsed configuration and a second expanded configuration;

a suture coupled to the adjustable ligation member; and

a manipulation tool, the manipulation tool including a working element on a distal end thereof, the working element configured to grasp tissue;

wherein the adjustable ligation member is sized so as to be placed about grasped tissue in the second expanded configuration, and tightened about the grasped tissue in the first collapsed configuration.

14. The marking system of claim 13, wherein the working element includes a pair of forceps positioned on a distal end of the manipulation tool.

15. The marking system of claim 13, wherein the tissue includes prostate tissue.

16. A method of treating tissue, comprising:

delivering a marking device to a position proximate target tissue;

adjusting the marking device to transition between a closed configuration and an open configuration;

securing the marking device on the target tissue while in the open configuration; and

severing the target tissue from remaining tissue portions while the marking device is secured on the target tissue.

17. The method of claim 16, wherein severing the target tissue includes enucleating the target tissue so as to be separated from remaining tissue portions.

18. The method of claim 16, further including:

urging the severed target tissue and marking device into a bladder of a patient.

19. The method of claim 18, further including:

morcellating the target tissue within the bladder.

20. The method of claim 19, further including:

coupling a morcellator device to the marking device via a suture, wire, or string.
