Systems and methods for stone removal

InactiveUS20090287193A1Stretch and draw down the width of the materialCompact lengthBalloon catheterSurgeryKidneyKidney stones
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.

Oscillating lithotripter tip

A tip element for a lithotripter is provided. The tip element includes a proximal end configured for attachment to a waveguide of the lithotripter and a distal end configured for placement against at least one urinary tract stone. The lithotripter transmits energy from the tip element to the at least one urinary tract stone to break up the at least one urinary tract stone into fragments. The tip element may further include a tip element passage that extends between the proximal end and the distal end. The tip element passage communicates with a lumen of the waveguide for at least one of suctioning and irrigating a urinary tract. The distal end has one or more sharp edges to maintain contact between the at least one urinary tract stone and the distal end during suctioning. The distal end may be configured to limit the size of fragments from the at least one urinary tract stone drawn into the tip element passage during suctioning.

Methods and devices for diagnosis of particles in biological fluids

Methods for determining whether certain compounds, in particular crystals, are present in a sample of a biological fluid that indicates an individual has a particular disease or condition, such as but not limited to gout, pseudogout or urinary tract stones. In some embodiments, the methods include the steps of digestion and filtration of a sample of synovial fluid in order to isolate, if present, monosodium urate monohydrate (MSU), calcium pyrophosphate dihydrate (CPPD), or calcium phosphate crystals from the sample, wherein the filtrate is analyzed with a Raman device to ascertain the presence and type of the crystals. Devices for performing steps of the method are disclosed.
