Abstract

A single trigger 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 configured to deploy and implant anchor devices for such purposes.

Claims

1. A method for treating a prostate involving an anchor delivery device including a trigger and an extendable element and at least one anchor assembly including a first anchor component, a connector and a second anchor component, comprising:

placing the extendable element at a first site;

actuating the trigger to advance the first anchor component through the extendable element;

retracting the extendable element from the first site;

employing the anchor delivery device to apply a pre-determined tension on the connector;

actuating the trigger to assemble the second anchor component to the connector; and

releasing the second anchor component at a second site.

2. The method of claim 1, wherein the anchor delivery device can be configured to apply a desired tensile force on the connector.

3. The method of claim 1, further comprising:

extending the extendable element from an original position; and

retracting the extendable element to the original position.

4. The method of claim 1, wherein the pre-determined tension is between approximately one-half and approximately 5 pounds of force on the connector.

5. The method of claim 1, wherein the pre-determined tension is approximately 1 pound of force on the connector.

6. The method of claim 1, wherein the anchor delivery device includes a scope, further comprising employing the scope to remotely view prostate treatment.

7. The method of claim 1, further comprising assembling the anchor assembly to a desired length.

8. The method of claim 1, further comprising assembling a plurality of anchor assemblies.

9. The method of claim 1, wherein each of the anchor assemblies can have a unique length.

10. The method of claim 1, further comprising severing the connector to a selected length.

11. The method of claim 1, wherein the extendable element is a needle assembly operatively associated with the trigger.

12. The method of claim 11, wherein the needle assembly can be advanced to variable, selectable depths within a patient.

13. The method of claim 11, wherein placing the extendable element at a desired first site involves varying a depth to which the needle assembly is placed within a patient.

14. The method of claim 13, further comprising delivering botulinum toxin to the prostate.

15. The method of claim 13, further comprising delivering 100 to 200 units of botulinum toxin dissolved in 4 mL of saline to the prostate.

16. The method of claim 15, wherein preferably 2 mL are injected in each lobe of the prostate.

17. The method of claim 13, further comprising delivering botulinum toxin to a bladder.

18. The method of claim 13, further comprising delivering 100 to 300 units of botulinum toxin dissolved in 10 to 30 mL of saline into a base of a bladder, the bladder lateral walls and/or trigone.

19. The method of claim 1, wherein one or a series of first anchor components are initially attached to the connector, an initial engagement between the first anchor and connector being generally coaxial.

20. The method of claim 19, wherein the second anchor component initially engages the connector at a generally perpendicular angle to the connector.
