Enhanced Devices and Methods for Suture Placement

Improved devices and methods for suture placement, providing enhanced stability, precision, and efficiency in tissue repair, particularly in spinal surgery.

The original patent disclosed devices and methods for suture placement, but had limitations in terms of needle stability, precision, and efficiency. The new inventive concept addresses these limitations by introducing frictional engagement of the curved needle at multiple points, controlled needle advancement and retraction, and a malleable needle that can be bent to follow a curved path.

The enhanced devices and methods for suture placement comprise a suturing device with an elongate body and a retractable needle holder, configured to frictionally engage a curved needle at multiple points, ensuring improved stability and precision of suture placement. The device features an actuator that enables controlled needle advancement and retraction, reducing the risk of tissue damage and improving surgical efficiency. Additionally, the device can be used in minimally invasive spinal surgery, accurately locating and repairing dural sac tears, thereby reducing surgical complications and improving patient outcomes. The malleable needle allows for more precise and flexible suture placement in complex tissue geometries.

The new claims introduce the concept of frictional engagement of the curved needle at multiple points, controlled needle advancement and retraction, and a malleable needle that can be bent to follow a curved path, which are not present in the original patent. These features provide a significant improvement in stability, precision, and efficiency of suture placement, making the new inventive concept novel and non-obvious.

Alternative embodiments of the inventive concept could include varying the design of the needle holder, the type of actuator used, or the material composition of the malleable needle. Variations could also include adapting the device for use in different surgical procedures or anatomical locations.

The enhanced devices and methods for suture placement have significant commercial potential in the medical device industry, particularly in the fields of spinal surgery and minimally invasive procedures. The target market includes hospitals, surgical centers, and medical device manufacturers.
