Guidewire exchange systems to treat spinal stenosis
First Claim
1. A method of treating a patient, the method comprising:
- advancing a distal end of a guidewire into the patient'"'"'s body from a first site, advancing adjacent to a target tissue, and out of the body from a second site, while maintaining a proximal end of the guidewire outside the body at the first site;
coupling an end of the guidewire on or near a distal end of a surgical device outside of the body by inserting the end of the guidewire at an angle relative to the distal end of the surgical device into a channel at or near the distal end of the surgical device and rotating one or both of the end of the guidewire and the distal end of the surgical device to lock the guidewire and the surgical device together;
pulling the guidewire to guide the surgical device adjacent to the target tissue; and
withdrawing the surgical device and end of the guidewire from the patient while maintaining the guidewire within the body and de-coupling the end of the guidewire from the surgical device and coupling the end of the guidewire on or near a distal end of a second surgical device outside of the body by inserting the end of the guidewire at an angle relative to the distal end of the second surgical device into a channel at or near the distal end of the second surgical device and rotating one or both of the end of the guidewire and the distal end of the second surgical device to lock the guidewire and the second surgical device together,wherein at least one of the surgical device and the second surgical device comprises an abrasive surface.

Abstract
Guidewire exchange systems, devices and methods, for positioning and actuating surgical devices in a desired position between two tissues in a patient'"'"'s body are described. A guidewire may be coupled to a surgical device for positioning and actuating (e.g., urging against a target tissue). The guidewire may be exchanged between different surgical devices during the same procedure, and the guidewire and surgical devices may be releaseably or permanently coupled. The surgical device generally includes one or more guidewire coupling members. A system may include a guidewire and a surgical device having a guidewire coupling member. Methods, devices and systems may be used in open, less-invasive or percutaneous surgical procedures.

8. A method for guiding at least a portion of a surgical device to a desired position between two tissues in a patient'"'"'s body, the method comprising:
-
advancing a distal end of a guidewire into the patient'"'"'s body, between two tissues, and out of the body, while maintaining a proximal end of the guidewire outside the body; coupling the proximal end of the guidewire with at least one coupling member on or near a distal end of a surgical device outside of the body by inserting the proximal end of the guidewire at an angle relative to the distal end of the surgical device into a channel at or near the distal end of the surgical device and rotating one or both the proximal end of the guidewire and the distal end of the surgical device to lock the guidewire and the surgical device together; pulling the distal end of the guidewire to guide at least a portion of the surgical device to a desired position adjacent to the target tissue; withdrawing the surgical device and distal end of the guidewire proximally from the patient while maintaining the guidewire within the body and de-coupling the proximal end of the guidewire from the surgical device and coupling the proximal end of the guidewire with at least one coupling member on or near a distal end of a second surgical device outside of the body by inserting the proximal end of the guidewire at an angle relative to the distal end of the second surgical device into a channel of the coupling member and rotating one or both the proximal end of the guidewire and the distal end of the second surgical device to lock the guidewire and the second surgical device together; pulling the distal end of the guidewire to guide at least a portion of an abrasive surface of the second surgical device to a desired position adjacent to the target tissue. - View Dependent Claims (9, 10, 11)

12. A method for performing a procedure on a target tissue in a patient'"'"'s body, the method comprising:
-
coupling a proximal end of a guidewire with at least one coupling member on or near a distal end of a surgical device outside of the body by inserting the proximal end of the guidewire at an angle relative to the distal end of the surgical device into a channel at or near the distal end of the surgical device; pulling a distal end of the guidewire to guide at least a portion of the surgical device to a desired position between two tissues, such that an abrasive portion of the surgical device faces the target tissue and an atraumatic portion of the surgical device faces non-target tissue; performing a procedure on the target tissue by reciprocating the surgical device by applying tension to both a portion of the guidewire outside of the body and a proximal portion of the surgical device; and withdrawing the surgical device and proximal end of the guidewire from the patient while maintaining the guidewire within the body and de-coupling the proximal end of the guidewire from the surgical device, and coupling the proximal end of the guidewire on or near a distal end of a second surgical device outside of the body by inserting the proximal end of the guidewire at an angle relative to the distal end of the second surgical device into a channel at or near the distal end of the second surgical device.
