Abstract

In one embodiment, a medical device includes a needle and a catch. The catch has a body portion. The body portion of the catch defines a cavity. The catch is configured to be coupled to the needle such that at least a portion of the needle is disposed within the cavity.

First claim

What is claimed is:

1. A medical device for treatment of a pelvic condition, comprising:
a needle having a needle head; and
a catch having a body portion and a base portion, the body portion of the catch having a sidewall with an inner surface defining a funnel shaped cavity and a first opening in communication with the funnel shaped cavity, the first opening being larger than the needle head, the catch being configured to be coupled to the needle such that at least a portion of the needle is moved into the cavity via the first opening, the catch including a projection member extending from the sidewall inner surface and being configured to engage the needle to help couple the needle to the catch, the catch including a retention member configured to engage bodily tissue when the catch is disposed within a body of a patient.

2. The medical device of claim 1 , wherein the needle is configured to pierce the bodily tissue.

3. The medical device of claim 1 , wherein the needle head of the needle includes a tissue piercing portion, the tissue piercing portion being configured to be disposed within the cavity when the needle is coupled to the catch.

4. The medical device of claim 1 , further comprising:
a coupling member having a first end portion coupled to the needle and a second end portion coupled to the catch.

5. The medical device of claim 1 , wherein the catch includes an attachment portion, the attachment portion is configured to engage a delivery tool to removably couple the catch to the delivery tool.

6. The medical device of claim 1 , wherein the catch includes an attachment portion, the attachment portion is configured to engage a delivery tool to frictionally couple the catch to the delivery tool.

7. The medical device of claim 1 , wherein the catch includes an attachment portion, the attachment portion is configured to engage a delivery tool to removably couple the catch to the delivery tool, the needle being configured to be removably coupled to a carrier portion of the delivery tool.

8. The medical device of claim 1 , wherein the retention member extends from an outer surface of the sidewall.

9. The medical device of claim 1 , wherein the retention member is a first retention member, the catch includes a second retention member.

10. A medical device for treatment of a pelvic condition, comprising:
a delivery tool having a distal end portion, the distal end portion defining an opening, the distal end portion including a receiving portion and a carrier portion, the carrier portion configured to move out of the opening and towards the receiving portion, the receiving portion being disposed proximally from the opening;
a needle, the needle being configured to be removably coupled to the carrier portion of the delivery tool; and
a catch having a body portion and a base portion, the base portion being configured to prevent the needle from extending from the base portion, the body portion of the catch having a first opening portion and a sidewall having an inner surface defining a cavity, the catch being configured to be removably coupled to the receiving portion of the delivery tool such that the catch is configured to remain stationary with respect to the delivery tool as the carrier moves the needle towards the catch, the catch including a retention member configured to engage bodily tissue when the catch is disposed within a body of a patient.

11. The medical device of claim 10 , wherein the catch includes an attachment portion that is configured to frictionally couple the catch to the receiving portion of the delivery tool.

12. The medical device of claim 10 , wherein the needle is configured to pierce the bodily tissue.

13. The medical device of claim 10 , wherein the needle includes a tissue piercing portion, the tissue piercing portion being configured to be disposed within the cavity when the needle is coupled to the catch.

14. The medical device of claim 10 , further comprising:
a filament having a first end portion coupled to the needle and a second end portion coupled to the catch.

15. The medical device of claim 10 , wherein the cavity defined by the sidewall inner surface is funnel shaped.

16. The medical device of claim 10 , wherein the cavity defined by the sidewall inner surface is funnel shaped, the catch includes a projection extending from the sidewall inner surface.

17. The medical device of claim 10 , wherein the retention member extends from an outer surface of the sidewall.

18. The medical device of claim 10 , wherein the retention member is a first retention member, the catch includes a second retention member.
