Abstract

In one embodiment, a medical device includes a delivery tool having a carrier member, and a cartridge. The cartridge is coupled to the delivery tool. The cartridge defines an opening. The cartridge is configured to retain an anchor defining a lumen. The carrier member has a retracted configuration and an extended configuration. The carrier member is configured to extend through the lumen defined by the anchor and through the opening defined by the cartridge when the cartridge is coupled to the delivery tool and the carrier member is in its extended configuration.

First claim

What is claimed is:

1. A medical device, comprising:
a delivery tool having a distal end portion, and a carrier member, the distal end portion defining a carrier opening and a catch location, the catch location being disposed proximally from the carrier opening, the carrier member configured to move along a travel path from a position within the distal end portion, out of the carrier opening, and into a portion of a catch, the catch being removably coupled to the distal end portion, at least a portion of the carrier member being curved, at least a portion of the travel path being curved, the distal end portion defining a slot; and
a cartridge coupled to the distal end portion of the delivery tool, the cartridge having a longitudinal axis extending from a first end portion to a second end portion, the cartridge configured to be inserted into the slot, the cartridge including a coupling member configured to couple the cartridge to the delivery tool in response to the cartridge being disposed within the slot of the distal end portion, the cartridge defining an opening, the opening of the cartridge being disposed within the travel path of the carrier member, the cartridge being configured to retain an anchor defining a lumen, the cartridge including a biasing member, the biasing member being disposed within a cavity of the cartridge, the biasing member being disposed proximally of the opening of the cartridge, the anchor being attached to the catch via an attachment member,
wherein the distal end portion of the delivery tool includes a projection, the coupling member of the cartridge includes an aperture, the projection being configured to at least partially extend into the aperture to couple the cartridge to the delivery tool,
wherein the cartridge is coupled to the delivery tool such that a portion of the travel path of the carrier member is disposed between the biasing member of the cartridge and the projection of the delivery tool, and
wherein the carrier member is configured to extend through the lumen defined by the anchor and through the opening defined by the cartridge in response to the carrier member moving along the travel path.

2. The medical device of claim 1 , wherein the cavity is configured to retain the anchor.

3. The medical device of claim 1 , wherein the cartridge is configured to retain a plurality of anchors.

4. The medical device of claim 1 , wherein the delivery tool includes an actuation member configured to move the carrier member along the travel path.

5. The medical device of claim 1 , wherein the cartridge is removably coupled to the delivery tool.

6. The medical device of claim 1 , wherein the cartridge has a first end portion and a second end portion opposite the first end portion, the first end portion being disposed on a surface outside of the delivery tool and the second end portion being disposed on a surface inside of the delivery tool.

7. The medical device of claim 1 , wherein the biasing member is configured to move the plurality of anchors that are disposed within the cavity of the cartridge.

8. A medical device, comprising:
a delivery tool having a distal end portion, and a carrier member, the distal end portion defining a carrier opening, the delivery tool including a catch removably coupled to the distal end portion, the catch being disposed proximally from the carrier opening, the carrier member configured to move along a travel path from a position within the distal end portion, out of the carrier opening, and into a portion of the catch, at least a portion of the carrier member being curved, at least a portion of the travel path being curved, the distal end portion defining a slot;
a cartridge coupled to the distal end portion of the delivery tool, the cartridge having a base member and a coupling member that extends orthogonally to the base member, the base member of the cartridge being configured to be inserted into the slot of the distal end portion of the delivery tool, the cartridge defining an opening, the opening of the cartridge being disposed within the travel path of the carrier member; and
an anchor disposed within the cartridge, the anchor defining a lumen, the anchor being attached to the catch via an attachment member, the cartridge including a biasing member, the biasing member being disposed within a cavity of the cartridge, the biasing member being disposed proximally of the opening of the cartridge,
wherein the distal end portion of the delivery tool includes a projection, the coupling member of the cartridge includes an aperture, the projection being configured to at least partially extend into the aperture to couple the cartridge to the delivery tool,
wherein the cartridge is coupled to the delivery tool such that a portion of the travel path of the carrier member is disposed between the biasing member of the cartridge and the projection of the delivery tool,
wherein the carrier member is configured to extend through the lumen of the anchor, through the opening of the cartridge, and through bodily tissue in response to the carrier member moving along the travel path and,
wherein the catch, the anchor, and the attachment member are configured to collectively form a loop about an implant and bodily tissue in response to the carrier member moving along the travel path.

9. The medical device of claim 8 , wherein the distal end portion of the delivery tool defines a curved opening, the cartridge being disposed within the curved opening when the cartridge is disposed within the slot of the distal end portion.

10. The medical device of claim 8 , wherein the cartridge is configured to retain the anchor, the cartridge being configured to be removably coupled to the delivery tool.

11. The medical device of claim 8 , wherein the attachment member is a suture, the suture having a first end portion coupled to the anchor and a second end portion coupled to the catch.
