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 system for altering the crossectional morphology of a lumen within the body of a human or animal subject, said system comprising:

an introduction device positionable within the lumen, the introduction device including a working device lumen having a lumen opening emerging from the introduction device, the working device lumen having a fixed, longitudinally curved lumen communicating with the working device lumen opening to establish a predefined angle transverse to a longitudinal axis of the introduction device;

an extendable member projecting from the introduction device proximal from a terminal end of the introduction device through the fixed curve lumen and working device lumen opening at the angle of the predefined angle transverse to a longitudinal axis of the introduction device;

a permanently implantable device that is introduceable through the introduction device into an opening in the lumen, said device being useable to modify the forces exerted on the lumen by tissue outside of the lumen, thereby resulting in a change of the crossectional morphology of the lumen.

2. A system according to claim 1 wherein the lumen within the body comprises the urethra and the device modifies forces exerted by the prostate gland on the urethra.

3. A system according to claim 1 wherein the lumen within the body comprises a blood vessel and the device modifies forces exerted on the blood vessel by tissue adjacent thereto.

4. A system according to claim 1 wherein the lumen within the body comprises a lumen of the trachea, bronchus, bronchiole or other respiratory passageway and the device modifies forces exerted on that trachea, bronchus, bronchiole or other respiratory passageway by tissue adjacent thereto.

5. A system according to claim 1 wherein the lumen within the body comprises a lumen of the stomach, duodenum, small intestine, jejunum, illium, colon, cystic duct, hepatic duct, common bile duct, pancreatic duct or other alimentary or endocrine passageway and the device modifies forces exerted on that trachea, stomach, duodenum, small intestine, jejunum, illium, colon, cystic duct, hepatic duct, common bile duct, pancreatic duct or other alimentary or endocrine passageway by tissue adjacent thereto.

6. A system according to claim 1 wherein the lumen within the body comprises a lumen of a lymphatic passageway and the device modifies forces exerted on that lymphatic passageway by tissue adjacent thereto.

7. A system according to claim 1 wherein the tissue comprises an organ.

8. A system according to claim 1 wherein the tissue comprises a neoplasm, benign growth, cancerous growth, tumor, cyst or other mass.

9. A system according to claim 1 wherein the tissue comprises congenital deformity.

10. A system according to claim 1 wherein the tissue comprises an anatomical structure that has become enlarged due to hypertrophy, hyperplasia, edema, fluid build up, fluid retention, excess fluid production, impeded fluid outflow, a tumor.

11. A system according to claim 1 wherein the curved portion is a distal portion of the working device lumen of the introduction device.

12. A system according to claim 11 wherein the extendable member is a needle.

13. A system according to claim 11 further comprising a trocar sized to be translatable within the introduction device.

14. A system according to claim 11 further comprising an anchor delivery device sized to be received by the introduction device.

15. A system according to claim 11 wherein the introduction device includes the working device lumen and a second lumen.

16. A system according to claim 15 wherein the working device lumen includes the curved portion.

17. A system according to claim 16 further comprising a cystoscope and wherein the second lumen is sized to receive the cystoscope.
