  • Patent number: 8951273
    Abstract: A surgical instrument for endoscopic surgery having a solid or transparent body and open windows on each of the opposing sides at the distal end, proximate a top open region. The open windows can be arcs or other configurations either open or with bars which are generally integral with the top and extend across the windows. An integrated tissue retractor spring, once activated, extends above the open region and when not activated rests within the open region. A marking member, that can be in fluid contact with a marking reservoir, can be placed at the distal end of the body. In another embodiment the body can be curved using a flexible blade shaft. In a further embodiment the handle has a linear body, containing a blade activation mechanism, at least one activation trigger, and a connector means.

  • Patent number: 8702654
    Abstract: An apparatus and method for identifying the flexor retinaculum of the carpal tunnel, injecting an effective amount of an agent into at least a portion of flexor retinaculum or tissue adjacent thereto, wherein the agent is configured to weaken the flexor retinaculum. The system may further include means for increasing the tensile stress in the flexor retinaculum post-injection using hand exercises, thereby weakening its structural integrity and decreasing the pressure within the carpal tunnel that impairs median nerve function.

  • Publication number: 20110028789
    Abstract: There is disclosed a method of gaining access to a lateral side of a spinal column for a spinal fusion procedure at a surgical site. In an embodiment, the method includes inserting a distal end of a shaft through skin at an entry point into a patient; steering the shaft toward a surgical site using a visualization device to avoid damage to structures between the entry point and the surgical site; and retracting tissue between the entry point and the surgical site to define a pathway for access to the lateral side of the spinal column for a spinal fusion procedure. Other embodiments are also disclosed.

  • Publication number: 20090234461
    Abstract: A prosthetic mesh and method of use in surgical methods for closure of abdominal incisions and prosthetics for repair of ventral hernias. The mesh provides for a new prosthetic that can be used for closure of laparotomy incisions, in patients at high risk for hernia formation, and in the repair of existing ventral hernias. The mesh utilizes existing multi laminar technology for intra peritoneal mesh, and fashions it in the shape of an intact Rectus Sheath. The mesh matrix can be made of any of the various absorbable or permanent polymer filaments that are woven or knitted into a scaffold for added strength to the abdominal wall closure during the healing phase, and for delivery of bio active substances that contribute to a biochemical milieu that contributes to favorable healing. A permanent non absorbable prosthesis will be desirable in certain circumstances and for particular patients, a slowly dissolving mesh would be ideal in most cases.

  • Patent number: 7447534
    Abstract: An electro-optic modulator modulates light in response to a life-form bio-potential to provide a bio-potential modulated light output. Modulation can be carried out as a result of capacitive coupling with the bio-potential. Phase, polarization, and intensity light modulation can be used. The light output can then be converted to electronic form for further processing. An optical power splitter is used to split light into multiple portions that are converted to electrical form. A pilot tone is used to achieve high sensitivity and synchronize multiple electro-optic modulators while phase modulation can be used to reduce noise in the bio-potential signal. Low-coherent light may be used as the light source. A housing is provided that can be hermetically-sealed and provided with electro-magnetic shielding.

  • Patent number: 5725479
    Abstract: A method for removing a vessel from a patient's body comprises the steps of identifying the vessel to be removing and providing an incision in the patient's body near the identified vessel. An optical dissector is inserted through the incision and tissue is optically dissected away from the surface of the vessel with the optical dissector. The optical dissector is then withdrawn from the body through the incision. An optical retractor is inserted into the body through the incision and is used to retract the dissected tissue away from the surface of the vessel thereby providing space between the dissected vessel and the retracted tissue. The vessel and its side branches are then dissected, ligated and transected and the vessel is then removed from the body through the incision.
