Patent number: 7822466Abstract: A system and method for CT guided instrument targeting including a radiolucent instrument driver; a robot and a control box. The robot includes a robotic module that positions the radiolucent driver about two directions coincident a predetermined point. The control device is connected to the robot and the radiolucent instrument driver. The control driver sends a robot control signal to the robot that causes the robotic module to place the radiolucent instrument driver in a desired orientation with respect to the predetermined point. After the radiolucent instrument driver is in the desired orientation, the control device sends a driver control signal to the radiolucent instrument driver that causes the radiolucent driver to insert a medical instrument or device through the predetermined point to a location proximate a target point in a patient.Type: GrantFiled: April 25, 2003Date of Patent: October 26, 2010Assignee: The Johns Hopkins UniversityInventors: Dan Stoianovici, Dumitru Mazilu, Louis R.

Patent number: 6599256Abstract: A tubular anatomical structure in a mammalian subject is occluded by directing ultrasonic energy from outside of the body. For example, a male subject may be sterilized by directing ultrasonic energy through the skin of the scrotum, onto the vas deferens. The focal spot of an ultrasonic transducer may be registered with the structure to be treated by means of guide members on a probe holding the transducer. The procedure is simple and can be entirely non-invasive. Apparatus for performing this and other treatments may be provided as a disposable unit, and the guide members may be arranged to hold a fold of tissue without substantially obstructing the sonic path from the transducer to the fold.Type: GrantFiled: September 11, 2000Date of Patent: July 29, 2003Assignee: Transurgical, Inc.Inventors: David E.

Patent number: 6400979Abstract: A method for performing radiological-image-guided percutaneous surgery with a system which includes a radiological image generating device for generating an image of a target anatomy of a patient, and a needle insertion mechanism disposed adjacent the image generating device and having a needle adapted to be inserted into the patient. The method includes the steps of: determining a needle trajectory of the needle by positioning the image generating device for aligning, in the image generated by the image generating device, a desired skin insertion site of the patient with a target region of the target anatomy; locking the needle in a direction of the needle trajectory; and repositioning the image generating device to obtain a lateral view of the needle trajectory for viewing an insertion depth and path of the needle during its insertion into the patient.Type: GrantFiled: February 20, 1998Date of Patent: June 4, 2002Assignee: Johns Hopkins UniversityInventors: Dan Stoianovici, Louis R.

Patent number: 6337994Abstract: An electrical impedance probe is provided that includes a surgical needle. In an exemplary embodiment, the probe is a two-part trocar needle designed to acquire impedance measurements at its tip. The impedance measurements are representative of the local properties of a biological substance at the needle tip. Thus, the probe may be used to confirm needle insertion into a desired anatomical target or to identify the nature of the cells surrounding the tip of the needle. In urology, this sensor is used for confirming the needle insertion into the urinary tract, for localizing renal cell carcinoma, and prostate cancer.Type: GrantFiled: April 27, 1999Date of Patent: January 8, 2002Assignee: Johns Hopkins UniversityInventors: Dan Stoianovici, Louis R.
