20130274791 | APPARATUS FOR OCCLUDING BODY LUMENS - 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. | 10-17-2013 |
20110172678 | METHODS AND APPARATUS FOR DEPLOYING URETERAL STENTS - A ureteral decompression device comprises a guide member and an anchoring structure. The guide member may be introduced through the urethra and bladder into the ureter so that the anchor structure passes a lodged kidney stone. Once past the stone, the anchor structure can be compacted to anchor the guide member in place. The anchor structure will permit leakage and the guide member will provide a leakage path directly past the stone, thus decompressing the kidney. | 07-14-2011 |
20110098690 | METHODS FOR REMOVING KIDNEY STONES FROM THE URETER - 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. | 04-28-2011 |
20090287238 | METHODS AND APPARATUS FOR DEPLOYING SHORT LENGTH URETERAL STENTS - 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 for a variety of purposes, including removing obstructions from the body lumen, such as kidney stones from the ureter; providing hemostasis in a blood vessel; providing occlusion of a fallopian tube; temporary constraint of stone fragments in the urinary tract; capture or restraint of clot in blood vessels; and the like. Apparatus for performing the method may comprise a length of material attached at its distal end to tubular guide or other advancement member. Tensioning members may also be provided for collapsing and compacting the length of material within the body lumen. | 11-19-2009 |
20090287193 | SYSTEMS AND METHODS FOR STONE REMOVAL - 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. | 11-19-2009 |
