Abstract

A system and associated method for manipulating tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders or other purposes. In one aspect, the system includes a delivery device and a plurality of anchor assemblies. The delivery system is configured to deliver a first anchor using loaded energy and reload the energy required to deliver an addition anchor.

Claims

1. A system for deploying an anchor assembly, comprising:

a cartridge carrying the anchor assembly, wherein the cartridge comprises a needle,

a handle configured to couple with the cartridge such that mechanical energy loaded in at least one spring mechanism within the handle is transferred to the cartridge to deploy the anchor assembly;

an actuator configured to initiate transfer of the mechanical energy and restore the majority of the mechanical energy to the at least one spring mechanism; and

an insert configured to couple with the handle, wherein prior to removal of the insert the at least one spring mechanism is loaded with less mechanical energy than is sufficient to deliver the anchor assembly.

2. The system of claim 1 wherein the actuator is configured to restore the majority of the mechanical energy during deployment of the anchor assembly.

3. The system of claim 1 wherein the actuator is configured to be activated more than one time to completely deploy the anchor assembly and restore the majority of the mechanical energy.

4. The system of claim 2 wherein the actuator is configured to restore mechanical energy to the at least one spring mechanism sufficient to deploy a second anchor assembly from a second cartridge.

5. The system of claim 1 wherein the cartridge is removable from the handle without releasing the mechanical energy in the at least one spring mechanism.

6. The system of claim 1 wherein the anchor assembly comprises a first anchor, a connector, and a second anchor.

7. The system of claim 1 wherein the cartridge further comprises an elongate member configured to access an interventional site adjacent a prostate.

8. The system of claim 1 wherein the insert is configured such that removal of the insert loads mechanical energy in the at least one spring mechanism sufficient to deliver the anchor assembly.

9. The system of claim 1 wherein prior to removal of the insert the at least one spring mechanism is in an unloaded state.

10. The system of claim 1 where the anchor assembly includes a customizable-length connector element.

11. The system of claim 1 further comprising a scope, wherein the cartridge is configured such that insertion and removal of the cartridge can be completed without removal or adjustment to the scope.
