Patents by Inventor Ricardo G. Hahn

Ricardo G. Hahn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9216029
    Abstract: This application presents a bifurcated, optimally-angled surgical forceps. In one example, this surgical forceps may enable a more natural maneuver for initial clamping of the vas deferens through the scrotal skin. This may be more comfortable for users and easier to maintain, and may provide greater tactile surface contact between the thumb and vas deferens. This device also may provide the surgeon with an entire segment of vas deferens upon which the vasectomy may be performed, thus reducing the need for frequent repositioning of instruments. The device may also be applied to other surgical procedures that may benefit from the features of the device and where a section of a tubular anatomical structure may need clamping at two points along its length. Examples include blood and lymphatic vessels, ducts of the digestive system, and large nerves or nerve bundles.

  • Patent number: 8985118
    Abstract: This application presents retention devices that afford the user quick and easy placement. These retention devices may accommodate objects of various shapes and sizes. The device provides sturdy means for retaining and securing an object to a surface without the need to handle and position flaps of tape. The device allows easy removal from the retained object without adhesives directly contacting or damaging it sensitive surfaces. The retention described here may be used to quickly secure anatomic structures during operations, such as securing the penis against the abdomen during vasectomy, without causing discomfort or damage to sensitive skin during application or removal.
