Devices, systems and methods for treating benign prostatic hyperplasia and other conditions
View Patent ↗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).
1. A device for compressing at least one region of the prostate comprising:
a first element configured to communicate force to an anatomical structure outside of the urethra, the first element defining a tubular body having a circumference, a mid-section, an open first end, an open second end, and an opening located near the mid-section extending laterally less than a full circumference and about at least a half of the circumference;
a second element configured to communicate force to the urethra; and
a tethering element capable of linking the first and second elements;
wherein the tethering element is configured within the tubular body and extends from the first end of the first element and exits an interior of the tubular body at the mid-section of the first element, and the second element is slid over and locked to the tethering element.
2. The device of claim 1 , wherein the second element is sized and shaped to be received within the urethra.
3. The device of claim 1 , wherein the first element is sized and shaped to be retained within the prostate.
4. The device of claim 1 , wherein the first element is sized and shaped to pass through a prostate and to be placed in a position outside a prostate capsule.
5. The device of claim 1 , wherein the device lacks a spring.
6. A device for relieving an obstruction of a lumen in the body due to encroachment of a tissue within or outside the lumen comprising:
at least one first element capable of communicating force to an anatomical structure outside of the lumen, the first element defining a tubular body having a circumference, a mid-section, an open first end, an open second end terminating with an narrowed portion, and an opening located near the mid-section extending laterally less than a full circumference and about at least a half of the circumference, the opening providing the tubular body with a longitudinal flexibility;
at least one second element capable of communicating force to the inner surface of the lumen;
a tethering element capable of linking the first and second elements;
wherein the tethering element is configured within the tubular body and extends from the first end of the first element and exits an interior of the tubular body at the mid-section of the first element, and the second element is slid over and locked to the tethering element.
7. The device of claim 6 , wherein the second element is sized and shaped to be received within an urethra.
8. The device of claim 6 , wherein the first element is sized and shaped to be retained within a prostate.
9. The device of claim 6 , wherein the first element is sized and shaped to pass through a prostate and to be placed in a position outside a prostate capsule.
10. The device of claim 6 , wherein the device lacks a spring.
