Abstract: A method comprises providing a lens blank, a precision positioning device, an illumination device, and a vision system, wherein the lens blank includes at least one feature whose position is known relative to a position of an optic center of the lens blank, and wherein the vision system comprises an image sensor and a processor; mounting the lens blank on the precision positioning device; illuminating the lens blank with the illumination device; viewing the lens blank with image sensor of the vision system; determining the position of the at least one feature using the processor; and determining the position of the optic center of the lens blank based on the position of the at least one feature using the processor.

Abstract: The present invention provides an apparatus for guiding a medical instrument. The medical apparatus includes a bracket member having a cavity dimensioned and configured to receive at least a portion of a medical instrument. A carriage member is slidably connected to a base assembly adapted to move the carriage member into an imaging position. The carriage assembly is adapted to rotationally support the bracket member, as well as provide a vertically adjustable height of the bracket member. A quick release member is operatively associated with the bracket and carriage members for removably attaching and detaching the bracket member to and from the carriage member when the carriage member is in the imaging position without losing the position and orientation of the carriage member.

Abstract: A system is provided for supporting a patient during computed axial tomography imaging. The system includes a movable platform formed of a radiolucent material, a discrete attachment region in the platform, and a curvilinear articulating arm coupled to the platform at the discrete attachment region. A method for supporting a patient during a plurality of procedures also is provided. The method includes: disposing the patient on a movable platform formed of a radiolucent material; positioning a device with respect to the patient, the device being disposed on a curvilinear articulating arm coupled to the platform; placing the platform, positioned device, and patient in a computed axial tomography imaging system and performing an imaging procedure.

Abstract: The present invention relates to a medical device guide, such as a template guide. The device guide includes a frame a frame having a plurality of network supports. A wire network is supported by the network supports thereby forming a plurality of meshes. A medical device may be inserted through one of the meshes to guide a position of the medical device.

Abstract: A suturing system and method for suturing first and second tissue sections is described. The system includes an elongate member having paired distal and proximal channels. The distal channel extends in the elongate member from the proximal end to a distal aperture and receives the distal end portion and at least a part of the body portion of a suture. The first proximal channel extends in the elongate member from the proximal end to a first proximal aperture and receives the proximal end portion and at least a part of the body portion of the suture. The elongate member is positioned between the first and second tissue sections with the suture in the first distal and first proximal channels such that a part of the body portion extends from the proximal end of the elongate member. The distal end of the suture passes through the first tissue section and the proximal end of the first suture passes through the second tissue section.

Abstract: A template grid is provided for use in positioning medical implants. The template grid includes apertures defining passages extending through the template grid. The passages are sized to accommodate a medical implant such as needles. The template grid further includes an elongated slot. The elongated slot allows a needle to be placed in Denonvilliers space at a desired angle so that the injection of fluid can be accomplished. The elongated slot also allows at least one posteriorly angled treatment probe to be placed below the urethra into the prostate to treat otherwise difficult to reach areas. The template grid can be made in multiple components so that it can be used in different configurations to suit the user's needs.

Abstract: The present invention relates to a medical instrument positioning device for controlled placement of a wide variety of medical instruments, such as an ultrasound transducer probe. The positioning device comprises a base member and a central shaft operatively associated with the base, a carriage member having a cavity configured and dimensioned to receive at least a portion of a medical instrument and slideably connected to the central shaft, a drive member coupled to the carriage member and engageable with the central shaft for movement with the central shaft and disengagement from the central shaft for sliding movement along the central shaft, and a quick release member operatively associated with the drive member. The quick release member has an inactive configuration in which the drive member engages the central shaft and an active configuration in which the drive member disengages the central shaft.

Abstract: A device is disclosed to retract eyelid by employing the friction and adhesion between the device and the outer surface of the eyelid of an eye without engaging the inside of the eyelid, thus without giving rise to infection, contamination, or injury to the eye. The device comprises a pair of arms joined at a joint. The arms are in a wishbone form with a size and configuration that accommodate the anatomy of the eye. The arms can be embodied in several preferred ways so that the size and configuration of the wishbone can be changed dynamically, adjusted resiliently, or fixed manually. The device is efficient enough to assist an eye care clinician to gain greater access to the exposed surface of an eyeball during an eye care procedure and is simple enough to aid contact lens patients in the process of inserting or removing contact lenses.
