  • Patent number: 8182422
    Abstract: An endoscope assembly with a main imaging device and a first light source is configured to provide a forward view of a body cavity, and further includes a detachable imaging device with an attachment member engageable with the distal end region of the endoscope, a linking member connected to the attachment member, and an imaging element with a second light source, wherein the detachable imaging device provides a retrograde view of the body cavity and the main imaging device. Light interference is reduced by using polarizing filters or by alternating the on/off state of the main imaging device, the first light source, the imaging element and the second light source so that the main imaging device and first light source are on when the imaging element and second light source are off and the main imaging device and first light source are off when the imaging element and second light source are on.

  • Publication number: 20110098690
    Abstract: Occluding structures may be created within a body lumen by advancing a length of material distally through the body lumen. By drawing a distal location on the advanced length of material in a proximal direction, the material may be compacted into a structure which at least partially occludes the lumen. The occluding structure may be used to remove kidney stones from the ureter in conjunction with lithotripsy and irrigation.

  • Patent number: 7879066
    Abstract: A luminal occlusion device comprises a tension member, an elongate shaft, and a flat film having an axial receptacle which is received over a distal portion of the tension member. The flat film has proximal and distal ends which are attached to the distal ends of the tension member and the elongate shaft, respectively. Thus, distal advancement of the tension member relative to the shaft will cause the flat film to assume a low profile configuration, while proximal retraction of the tension member relative to the elongate shaft will cause the flat film to assume a foreshortened, compacted configuration. The film usually includes one or more radioopaque markers which help shape the compacted film.

  • Publication number: 20100137846
    Abstract: A stone capture device comprises a shaft with a deployable sweeping structure at its distal end. The shaft is adapted to be removably placed over and connected to a conventional ureteroscope. The combination of the stone capture device and ureteroscope can be introduced into the urinary tract to capture, fragment, and remove stones from the bladder and kidney.

  • Publication number: 20090287193
    Abstract: A stone removal system comprises a sweeping structure and a dilating structure. The sweeping structure is deployed on a kidney side of a urinary stone in the ureter. Should the sweeping structure be unable to remove the kidney stone, the dilating structure is placed on the bladder side of the kidney stone and used to dilate the lumen of the ureter. The dilated lumen allows the sweeping structure to more easily remove the kidney stone. Should the kidney stone still resist removal, a lithotripsy device may be introduced through the ureter and energy directed through openings in the dilation structure to fragment the stone.

  • Publication number: 20080172037
    Abstract: The catheter includes an inner column and an outer elastic member. The inner column is bendable wherein the column strength and flexibility of the inner column are adjusted by axially tensioning the outer elastic member. The inner column comprises a helical spring, slotted or slit tube, or individual links that, when axially compressed by advancement forces or by tensioning an elastic outer sheath, assume a straight or other pre-determined geometry. The column strength and flexibility of the catheter may be adjusted during introduction of the catheter into a body lumen as necessitated by the conditions encountered, as well as made highly flexible when left in position.

  • Publication number: 20070015989
    Abstract: An endoscope is communicatively coupled to electronics that receive images of tissue from the endoscope and determine a correlation between the received images and images of normal and abnormal tissues in a database. Based on the determined correlation, an operator of the endoscope is notified of the correlation and the electronics can cause the endoscope to act accordingly (e.g., biopsy abnormal tissue).
