| 20080269798 | EMBOLECTOMY DEVICE - An embodiment is a catheter comprising a first elongate shaft having a proximal end, a distal end and a first lumen therethrough, a wire having a proximal end and a distal end at least partially disposed in the first elongate shaft, the distal end extending distally from the first elongate shaft, and a motion control apparatus connected to the proximal end of the wire, further comprising a device attached to the distal end of the wire for changing the shape of an embolus, wherein the device is configured to change the shape of the embolus to unclog a distal catheter lumen. | 10-30-2008 |
| 20080306583 | HYBRID BALLON EXPANDABLE/SELF-EXPANDING STENT - A stent comprises a tubular member having openings therein and having a plurality of interconnected members and one or more frangible restraining members. The frangible restraining members break upon partial expansion of the stent. Thereafter, the stent self-expands. | 12-11-2008 |
| 20090018653 | HYBRID AND PORTABLE POWER SUPPLIES FOR ELECTROLYTICALLY DETACHING IMPLANTABLE MEDICAL DEVICES - A medical system comprises a power supply coupled to an implant assembly, the power supply configured for detecting an energy delivery type of the implantable assembly and delivering electrical energy to the implant assembly in a mode corresponding to the detected energy delivery type, thereby electrolytically severing the joint. In another embodiment, a power supply is provided for use with a medical device having an elongated member and a terminal disposed on a proximal end of the elongated member. The power supply including power delivery circuitry, an electrical contact coupled to the power delivery circuitry, a port configured for receiving the proximal end of the elongated member, and an electrically insulative compliant member configured for urging the electrical terminal into contact with the electrical contact when the proximal end of the elongated member is received into the port. | 01-15-2009 |
| 20090024154 | POWER SUPPLY USING TIME VARYING SIGNAL FOR ELECTROLYTICALLY DETACHING IMPLANTABLE DEVICE - A medical system comprises an implant assembly including an elongated pusher member, an implantable device (e.g., a vaso-occlusive device) mounted to the distal end of the pusher member, and an electrolytically severable joint disposed on the pusher member, wherein the implantable device detaches from the pusher member when the severable joint is severed, the medical system comprising an electrical power supply coupled to the implant assembly, and configured for conveying a time varying signal having net positive electrical energy to the severable joint to detach the implantable device from the pusher member. | 01-22-2009 |
| 20090143786 | IMPLANTABLE DEVICE WITH ELECTROLYTICALLY DETACHABLE JUNCTION HAVING MULTIPLE FINE WIRES AND METHOD OF INTRODUCTION - Electrolytically detachable implantable devices and methods of delivering the same to a treatment site. An assembly includes an implantable device, such as a vaso-occlusive coil, a conductive deployment mechanism, such as a conductive pusher or wire, and a temporary connection between the deployment mechanism and the coil in the form of an electrolytically detachable junction. The detachable junction includes fine wires, e.g., stainless steel wires having a small diameter of about 0.00001″ to about 0.0025″, for example, about 0.0005″. The pusher or wire is used to deliver the implantable device through a catheter and to a desired location or treatment site. After the implantable device is properly positioned, electrical current is applied to the fine wires, thereby simultaneously disintegrating the fine wires and leaving the coil at the treatment site. | 06-04-2009 |
| 20100222806 | EMBOLUS EXTRACTOR - An embolus extractor including elongate shaft having a proximal end and a distal end. The embolus extractor may include primary struts coupled to the distal end of the shaft. The struts may define a proximally disposed mouth. Additional secondary struts may be coupled along the elongate shaft to enhance the thrombus containing ability of the embolus extractor. | 09-02-2010 |
| 20100234935 | Detachable And Retrievable Stent Assembly - A stent assembly comprises an expandable stent having a first stent backbone which extends from the proximal end of the stent to the distal end of the stent. The stent comprises a first stent back bone oriented in a direction which is substantially parallel to a longitudinal axis of the stent, and a plurality of interconnected first stent members and second stent members. Each of the first stent members is oriented in a substantially longitudinal direction in the unexpanded state and the expanded state. Each of the second stent members is oriented in a substantially longitudinal direction in the unexpanded state and oriented in a substantially circumferential direction in the expanded state. The first stent backbone has a greater column strength than that of the plurality of interconnected stent members. | 09-16-2010 |
| 20110054589 | STENT WITH VARIABLE CROSS SECTION BRAIDING FILAMENT AND METHOD FOR MAKING SAME - A braided stent comprises a filament having at least one circular zone and at least two non-circular zones. Embodiments of the braided stent have a proximal segment, a middle segment, and a distal segment, wherein a porosity of the middle segment is lower than, a respective porosity of the proximal and distal segments. In one embodiment, a radial pressure of the middle segment is separately controlled to be different from, e.g., less than, a radial pressure of the distal segment. In another embodiment, a stiffness of the middle segment is separately controlled to be different from, e.g., less than, a stiffness of the distal segment. | 03-03-2011 |
