| 20090030427 | HANDLE FOR INTERCHANGEABLE MEDICAL DEVICE - A rigid extractor is revealed, a rigid device for use in percutaneous procedures to remove kidney stones directly from the kidneys. The rigid extractor uses a handle fixed to an outer rigid cannula, and an inner cannula to control an extraction device that may be removable from the inner cannula. The extractor is desirably used with a fluoroscope, in which the surgeon maneuvers the extractor with the aid of a view of the operating field provided by the fluoroscope. The surgeon then maneuvers the extractor to grasp the kidney stones and remove from the patient. The extractor may also be used with a nephroscope. The device may be used with a removable extraction device such as a basket, a grasper a pair of jaws, or a pair of scissors. | 01-29-2009 |
| 20100010499 | HYDRAULIC GUIDEWIRE ADVANCEMENT SYSTEM - A hydraulic guidewire advancement system for enhancing access through lesions or occlusions in distal regions of a patient's vasculature includes a catheter comprising a sheath, a guidewire lumen, and a proximal catheter port connected to a hydraulic driver. A hydraulic guidewire is coaxially disposed through the guidewire lumen, the hydraulic guidewire comprising a piston movably disposed in the guidewire lumen, the piston forming a seal with an interior surface of the sheath. The hydraulic driver is configured to generate hydraulic pressure against the piston sufficient to advance or retract the hydraulic guidewire relative to the catheter. The hydraulic driver can apply positive or negative pressure to the piston, so as to repeatedly contact and break through the lesion with the distal end of the hydraulic guidewire. | 01-14-2010 |
| 20100049136 | Guide Wire and Method of Use Thereof - The present invention generally relates to a medical device and specifically to a guide wire for reversing the direction of catheterization within a body lumen and to a method of use thereof. In one embodiment, the guide wire includes a first elongated member having a second elongated member attached to the distal end. A spring element joins the distal end of the second elongated member to a third elongated member. The third elongated member is movable between a first position folded upon the second elongated member and a second position extending distally from the second elongated member. | 02-25-2010 |
| 20100049137 | Device for Crossing Occlusions and Method of Use Thereof - The present invention generally relates to a medical device and specifically to a catheter and wire guide for crossing an occlusion in a body lumen and a method of use thereof. In one embodiment, the catheter includes an incremental positioning mechanism positioned distally of the catheter body. In another embodiment, a lumen containing the wire guide extends through the incremental positioning mechanism and the catheter body. The incremental positioning mechanism allows for adjustment of the axial position of the wire guide relative to the distal end of the catheter body. | 02-25-2010 |
| 20100063488 | WIRE GUIDED THROMBECTOMY DEVICE - A medical device for removing a thrombus from a blood vessel and a process thereof is presented. The device comprises an outer sheath with a plurality of lumens. A wire guide inserted through one of the lumens is used to place the device proximate to a thrombus. An optical fiber placed through a second lumen uses laser input to ablate the thrombus in the proximal portion of the second lumen near its proximal end. A vacuum coupled to the distal end of the second lumen is used to remove any ablated residual material. The second lumen may be pivoted around the first lumen to reposition the second lumen proximate to an area of the thrombus that has not yet been ablated. | 03-11-2010 |
| 20100087844 | MECHANICAL THROMBECTOMY DEVICE - A medical device for removing a thrombus from a blood vessel and a process thereof is presented. The device comprises an outer sheath with a plurality of lumens. A wire guide inserted through one of the lumens is used to place the device proximate to a thrombus. A chemical lysin agent is used to at least partially lyse the thrombus. A wire basket extended through the first lumen proximate to the thrombus is translated back and forth to generate a force that may be transmitted to the partially lysed thrombus assisting in the formation of smaller fragments. A vacuum coupled to the distal end of the second lumen is used to remove the lysed thrombus fragments. | 04-08-2010 |
| 20100145356 | Irrigating Catch and Removal Device - A retrieval device is provided for capturing and retrieving stones, calculi, and other objects from a body. The retrieval device includes an irrigation orifice to irrigate a passageway. Irrigating the passageway helps to keep the viewing area free from debris and particulate matter. | 06-10-2010 |
| 20110144581 | METHOD FOR BONDING LOW-PROFILE RAPID EXCHANGE CATHETER - A low-profile rapid-exchange catheter device having desirable strength between joined proximal and distal portion may be constructed using a method that includes a textile sleeve and a thermoplastic polymer overlay. | 06-16-2011 |
