  • Patent number: 10413749
    Abstract: A brachytherapy seed localization system for localizing radioactive seeds within a diseased tissue, the brachytherapy seed localization system employs a tool tracking machine (50) for generating a tracked seed distribution map (51) of delivered locations of the radioactive seeds within the diseased tissue, and a tissue imaging machine (60) for generating a seed distribution image (61) of projected locations of the radioactive seeds within the diseased tissue including at least one false projected location. The brachytherapy seed localization system further employs a brachytherapy seed localizer (70) for generating a composite seed distribution map (71) of estimated locations of the radioactive seeds within the diseased tissue derived from a combination of the tracked seed distribution map (51) and the seed distribution image (61) excluding any false projected location(s) within the seed distribution image (61).

  • Patent number: 8571224
    Abstract: In various embodiments, a system is used to provide an apparatus configured to measure sound in an ear canal of a wearer's ear at a distance from a tympanic membrane of the ear. The sound is measured and received by the apparatus to produce a signal. A frequency analysis is performed on the signal to determine output as a function of the frequency and to determine the frequency of the minima (null). Further, a distance equal to a quarter wavelength of the null frequency is calculated. A correction factor associated with the quarter wavelength is retrieved and applied to the output to generate a corrected output. An estimated sound pressure level at the tympanic membrane from the corrected output is produced.

    Abstract: Positioning mechanisms can be used with surgical retractor systems to allow a surgeon to easily laterally move, tilt and lengthen each individual retractor blade used in the system. A lateral retraction mechanism provides the necessary actuating forces to laterally move and hold tissue at the surgical site. A retractor blade tilt mechanism can be used to change the angular position of a retractor blade at a surgical site. This tilt mechanism allows the surgeon to further increase the size of the surgical site by tilting one or more of the retractor blades allowing the distal end or toe of each blade to move laterally via a tilting action. A retractor blade holding mechanism allows the surgeon to hold each retractor blade in a fixed position within a blade holder and allows the surgeon to easily change the length of the retractor blade which extends out of the blade holder.

  • Patent number: 7749162
    Abstract: The present invention relates to a vaginal speculum embodying an applicator for the uniform delivery of a standardized dose of a liquid diagnostic marker onto the woman's lower genital tract. The applicator can comprises of a marker container and a mechanism for transferring a desirable quantity of its content to an injection probe for dispensing the marker onto the tissue surface. The cross section of the injection probe is substantially smaller than the rear opening of the speculum, so that the monitoring of the optical effects provoked to the tissue by the marker and the insertion of treatment tools is not obstructed.

  • Patent number: 7736307
    Abstract: Surgical devices for stabilizing the heart are disclosed which facilitate anastomosis under beating heart conditions. Various instruments or devices may be maneuvered and secured on a retractor device to provide stabilization of the heart. An instrument mount is provided which is preferably configured to accept a surgical instrument, such as a tissue stabilizer, and to allow the instrument to be easily maneuvered to a desired position and subsequently locked into position with a simple operation of a single locking actuator. Further disclosed are stabilizer devices each having at least one surface for contacting the heart and each being adapted to be mounted to the retractor while having the ability to be positioned in the desired location against the heart.

  • Patent number: 7654954
    Abstract: A surgical retractor having laterally extending rack with a first arm connected to the rack spaced from the second arm. A retractor clamp has a slot which engages one of the arms. Extending from the clamp is a leg with a mount which receives a connector head of a retractor blade. One or more retractor clamps may be advantageously positioned on either of the arms at a desired location. In the preferred embodiment, the mount is rotatable relative to a member housing the slot such that a retractor blade connected to the mount may be pivoted into and out of an incision. Furthermore the housing member is configured so that a hand held gripper may be connected to the connector head of a retractor blade as it extends through the mount.

  • Patent number: 7585277
    Abstract: Methods and devices which a surgeon may use to stabilize the beating heart during a surgical procedure on the heart. A stabilizing device may be introduced through an opening in the chest and brought into contact with the beating heart. By contacting the heart with the device and by exerting a stabilizing force on the device, the motion of the heart caused by the contraction of the heart muscles in a vicinity of a site of surgery to be performed, is effectively eliminated. A surgeon may contact the heart with the stabilizing means, assess the degree of movement of the anastomosis site, and exert a force on the stabilizing means such that the contraction of the beating heart causes only minimal excess motion at the surgery site. The stabilizing means may be attached to a rigid support or may be attached to a semi-rigid support which is rendered motionless mechanically, chemically, or by human intervention.

  • Patent number: 7468077
    Abstract: The distal end part of the retractor according to the invention is provided both with terminal tips for abutment on one of the femoral condylar walls which define therebetween the intercondylar space, and with a wing extending laterally in projection from this end part in order to form a frontal surface for thrust, in a medial-lateral direction, of that part of the quadriceps muscle tendon containing the patella when the tips are in abutment in the intercondylar space. By using this retractor as a lever, the wing efficiently reclines the patella, without turning it completely on itself, entirely exposing one of the femoral condyles. This invention is more particularly applicable to a surgical procedure for implanting a unicompartmental knee prosthesis.

  • Patent number: 7311664
    Abstract: An improved tissue engagement device such as a suction stabilizer or retractor. The stabilizer or retractor is provided with one or more suction pods mounted to the distal end of a flexible arm. The flexible arm is coupled to a base assembly, which attaches the arm to an associated retractor or other structure that is fixedly located relative to the operative site. The base assembly includes a fixed portion, which is coupled to the retractor or other fixed mounting point and a rotatable turret, allowing rotation of the arm relative to the fixed portion of the base assembly. A tensioning mechanism mounted to the turret applies tension to compress the turret around a corresponding pivot mounted to the fixed portion of the base to rotationally lock the turret and to lock the arm in its current configuration.

  • Patent number: 7250028
    Abstract: Devices, systems and methods related to endoscopic surgery, particularly related to robotic surgical operations, provide a tissue stabilizer for endoscopically stabilizing a target tissue within a patient's body. For stabilizing a beating heart during a closed-chest coronary artery bypass grafting procedure, a stabilizer is inserted through an endoscopic cannula and provides sufficient surface area to contact the heart and effectively stabilize the target tissue area. The stabilizer can straddle a blood vessel, such as a coronary artery, which is targeted for an anastomosis. Vessel occlusion fasteners may occlude the target blood vessel prior to the anastomosis procedure.

  • Patent number: 7241264
    Abstract: A malleable shaft device for use in surgical procedures, having a tension fiber therein, whereby the malleable shaft transitions from a malleable state to a rigid state when a force is applied to the tension fiber, has a variable-pitch cam operatively connected to the tension fiber, and a lever operatively connected to the variable pitch cam for applying force. The mechanical advantage of the cam changes with displacement to accommodate increasing load, and to increase the rate of travel while loads are light. The force profile may provide for a constant input force to accomplish the full travel of the cam.
