Abstract

Devices, systems and methods for compressing, cutting, incising, reconfiguring, remodeling, attaching, repositioning, supporting, dislocating or altering the composition of tissues or anatomical structures to alter their positional or force relationship to other tissues or anatomical structures. In some applications, the invention may be used to used to improve patency or fluid flow through a body lumen or cavity (e.g., to limit constriction of the urethra by an enlarged prostate gland).

Claims

1. A method of treating an anatomical region within a urinary tract of a patient, comprising:

providing a device comprising two or more spreading arms connected by a heel region, wherein the device has an undeployed configuration in which the spreading arms are held close to each other and a deployed configuration in which the spreading arms expand away from each other;

inserting the device into the urinary tract of the patient in the undeployed configuration;

positioning the device such that the spreading arms are near an anterior commissure of the patient;

deploying the device from the undeployed configuration to the deployed configuration to spread apart two lateral lobes of a prostate gland of the patient wherein a portion of the heel region penetrates into tissue when the device is in the deployed configuration.

2. The method of claim 1, wherein a portion of the spreading arms penetrates into tissue.

3. The method of claim 1, wherein a portion of at least one of the spreading arms comprises a flattened region.

4. The method of claim 1, wherein at least one of the spreading arms is curved.

5. The method of claim 1, wherein at least one of the spreading arms is straight.

6. The method of claim 1, wherein the spreading arms are configured to have a biasing force that tends to spread the spreading arms away from each other in the deployed configuration.

7. The method of claim 6, wherein the force causes cutting of the anterior commissure.

8. The method of claim 1, further comprising making an opening in the anterior commissure prior to deploying the device.

9. The method of claim 1, wherein a portion of the device penetrates into tissue of a prostate gland of the patient.

10. The method of claim 1, wherein a portion of the device penetrates into tissue of a urethra of the patient.

11. The method of claim 1, wherein the spreading arms are joined by the heel and the heel is positioned near an anterior commissure of the patient.

12. The method of claim 1, wherein the spreading arms are joined by the heel and the heel is positioned within an anterior commissure of the patient.

13. A method of treating a prostate gland within a urinary tract of a patient, comprising:

providing a device comprising two or more spreading arms connected by a heel region, wherein the device has an undeployed configuration in which the spreading arms are held close to each other and a deployed configuration in which the spreading arms expand away from each other via a biasing force that tends to spread the spreading arms away from each other;

inserting the device via a delivery tool into the urinary tract of the patient in the undeployed configuration;

positioning the device such that the spreading arms are near an anterior commissure with the prostate gland of the patient;

deploying the device from the undeployed configuration to the deployed configuration wherein the biasing force causes separation of the two lateral lobes near the anterior commis sure when the device is placed within a prostate gland of a patient.

14. The method of claim 13, wherein the spreading arms are joined by the heel and the heel is positioned near an anterior commissure of the patient.

15. The method of claim 13, wherein the spreading arms are joined by the heel and the heel is positioned within an anterior commissure of the patient.

16. The method of claim 13, wherein a portion of at least one of the spreading arms comprises a flattened region.

17. The method of claim 13, wherein at least one of the spreading arms is curved.

18. The method of claim 13, wherein at least one of the spreading arms is straight.

19. The method of claim 13, wherein the device is delivered by pushing the device out of a portion of a lumen of the delivery tool.

20. The method of claim 19, wherein the spreading arms of the device spread expand away from each other as the spreading arms emerge from the portion of the lumen.

21. The method of claim 13, wherein the device is detachably attached to the delivery tool by a detaching mechanism.
