Abstract
A surgical method of anchoring tissues in a target location, comprising tracking a cannulated dilator on a suture protruding from the target location and forming an enlarged opening in the target location using the cannulated dilator to enlarge the opening. A distal end of a guide wire is tracked through the dilator into the enlarged opening, and an anchoring device is slid on the guide wire to position the device in the enlarged opening. Advantageously, since the target location is dilated prior to receiving the anchoring device therein, a soft tissue disposed at the target location can be dilated before being anchored, to avoid possible damage to the tissue by the implanting device.
Claims22
A method of surgically anchoring a device in a target location, comprising:
- tracking a cannulated dilator on a suture, said suture protruding from a target location;
- forming an enlarged opening in said target location using said cannulated dilator;
- inserting a distal end of a guide wire into said enlarged opening through said cannulated dilator;
- sliding an anchoring device on said guide wire into said enlarged opening.
A surgical method of securing an anchoring device in a target location, comprising:
- grabbing a section of a flexible suture to get said suture from said target location, said suture extending through a first passageway to said target location;
- tracking a cannulated instrument over a first free end of said suture until a distal portion of said instrument penetrates said target location;
- enlarging said target location with said instrument to form an opening;
- removing said suture;
- inserting a guide wire through said cannulated dilator such that a distal end of said guidewire resides, at least in part, within said opening;
- retracting said instrument;
- and
- tracking an anchoring device over said guidewire such that said anchoring device is positioned, at least in part, within said opening.
A surgical method of implanting soft tissue in a target location, comprising:
- creating a first passageway and a second passageway that intersects said first passageway, in a target location;
- pulling a soft tissue into said first passageway;
- grabbing said suture from said first passageway through said second passageway to get a first free end of said suture;
- tracking a cannulated dilator over said first free end of said suture until a distal portion of said dilator penetrates a location in said soft tissue, through said second passageway;
- enlarging said location with said dilator to form an opening;
- removing said suture;
- inserting a guide wire through said cannulated dilator such that a distal end of said guidewire resides, at least in part, within said opening;
- retracting said dilator;
- tracking an anchoring device over said guidewire such that said anchoring device is positioned, at least in part, within said opening;
- and
- securing said soft tissue in said target location using said anchoring device.
A surgical kit for anchoring a device in a target location, said kit comprising instructions for performing surgical implantation procedures, said instructions including a method of securing an anchoring device in a target location, comprising:
- tracking a cannulated dilator on a suture, said suture protruding from a target location;
- forming an enlarged opening in said target location using said cannulated dilator, said enlarged opening defined by said suture and said cannulated dilator;
- inserting a distal end of a guide wire into said enlarged opening through said cannulated dilator;
- sliding an anchoring device on said guide wire into position in said enlarged opening.
