Abstract: A ureteral stent is designed to be placed within a patient's ureter to facilitate drainage from the patient's kidneys to the bladder. An elongated portion of the stent includes a length sufficient to extend substantially within the ureter from the kidney to the bladder, and the elongated portion defines a lumen extending therethrough. A retention portion extends from one end of the elongated portion and retains the position of the ureteral stent when placed substantially within the kidney. The retention portion includes an interior space that is in communication with the lumen within the elongated portion and has at least one opening for urine drainage. A flared portion extending from the other end of the elongated portion is positioned within the patient's bladder. The flared portion curves outward and includes an elastic member that maintains the shape of the flared portion when positioned within the bladder.

Abstract: A ureteral stent for assisting the movement of urine along a patient's ureter and into the patient's bladder. The stent includes an elongated tubular segment extending toward the bladder from a kidney end region for placement in the renal cavity to a bladder end region. A central lumen connects at least one opening at the first end region to at least one opening in the bladder end region. Thin flexible tail(s) are attached to the bladder end region of the tubular segment at a point outside the bladder so as to receive urine from the opening in the bladder end region of the tubular segment and to transport urine from there across the ureter/bladder junction and into the bladder. The tails include an elongated external urine-transport surface sized and configured to transport urine along the ureter. The urine transporting surface(s) are sized and configured to extend along at least part of the ureter, across the ureter/bladder junction, and from there into the bladder.

Abstract: A ureteral drainage stent is designed to be placed in a patient's ureter and extend into a patient's bladder. An elongated tubular segment includes a distal region for placement in the renal cavity, and a proximal region for placement in a urinary bladder. A central lumen connects at least one opening in the distal region to at least one opening in the proximal region. The elongated segment is constructed such that the wall surrounding the lumen is thinner in the proximal region than in the distal region. The thin-walled portion of the elongated segment extends along at least part of the ureter, across the ureteral vesicle junction, and from there into the bladder.

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.

Abstract: An apparatus for supporting and facilitating accurate positioning, both linearly and angularly of a medical device such as an ultrasound probe, a medical instrument or an imaging device. The apparatus is capable of both gross and precise multi-directional movements with the medical device attached, while remaining connected to stationary objects such as a portable floor stand and/or operating table. After gross manual placement and approximate positioning, the fine tune mechanism of the attached medical device is locked in positioned and secured to two fixed points. Exact positioning is then achieved by the precision movements which are available in all three linear directions and rotational axes. By this arrangement which allows preattachment of the medical device or instrument (i.e., an ultrasound probe) to the apparatus prior to positioning in the patient, quicker, more accurate and more reproducible medical device positioning and placement are achieved.

Abstract: A system for forming a liquid interface between a body tissue and an ultrasound probe which includes an ultrasound transducer. The system including a sheath including a liquid tight sack, wherein the sack covers, when the probe is placed inside the sheath, at least a portion of the probe where the ultrasound transducer is positioned but without covering an underside of the probe located on a diametrically opposite side from where the ultrasound transducer is positioned. The system also includes a tube connected to the sheath, wherein the sack expands to form the liquid interface when a liquid is introduced to the sack via the tube.

Abstract: A sterile disposable template grid system for positioning and implanting medical implants is disclosed. In one embodiment, the disposable template grid includes an attachment element that joins a front portion having front channels and a rear portion having rear channels so that the front channels align with the rear channels to form passages which allow medical implants to pass from the front portion through the rear portion. In another embodiment, the disposable template grid includes an insert having channels; a bracket sized to removably receive and support the insert and having apertures; and an alignment element for aligning the apertures with the channels to allow medical implants to pass from the apertures through the channels. Although the disposable template grid can be used with a wide variety of implants, it is particularly well suited for the radioactive seed containing needles used in brachytherapy.

Abstract: An apparatus for supporting and facilitating accurate positioning, both linearly and angularly of a medical device such as an ultrasound probe, a medical instrument or an imaging device. The apparatus is capable of both gross and precise omni-directional movements with the medical device attached, while remaining connected to stationary objects such as a portable floor stand and/or operating table. After gross manual placement and approximate positioning, the fine tune mechanism of the attached medical device is locked in positioned and secured to two fixed points. Exact positioning is then achieved by the precision movements which are available in all three linear directions and rotational axes. By this arrangement which allows preattachment of the medical device or instrument (i.e., an ultrasound probe) to the apparatus prior to positioning in the patient, quicker, more accurate and more reproducible medical device positioning and placement are achieved.

Abstract: Apparatus for a medical instrument includes bracket member having a cavity dimensioned and configured to receive at least a portion of the medical instrument; carriage member defining a recess adapted to rotationally support the bracket member; base assembly adapted to be slidably connected to support the carriage member; grid support member adapted to be connected to one end of the base assembly; and template grid, coupled to the grid support member, the template grid having a plurality of grid apertures. In one preferred embodiment, the medical instrument is an ultrasound probe.
