| 20100094269 | SYSTEMS AND METHODS FOR NAVIGATING AN INSTRUMENT THROUGH BONE - System and methods are shown having a tube-within-tube assembly with a deployable curved deflectable tube or cannula that deploys from a straight cannula or trocar. The curved cannula has pre-curved distal end to create an angular range of 0° to 180° when fully deployed from the straight trocar. The curve is configured such that the flexible element carrying a treatment device can navigate through the angular range of deployment of the curved cannula. The curved cannula allows the flexible element to navigate through a curve within bone without veering off towards an unintended direction. | 04-15-2010 |

The array elements are configured to be positioned within the aneurysm after the neck bridge is deployed from a delivery device. In a second embodiment, the neck bridge includes a junction region and a braided or mesh-like structure secured to the junction region. The braided or mesh-like structure is made from an elastic material. | 11-13-2008 |
| 20080319445 | Apparatus and methods for delivering compounds into vertebrae for vertebroplasty - An apparatus for delivering bone cement into a vertebra, includes a cannula, a delivery device in communication with the cannula and a pressure delivery device in communication with the delivery device. The pressure delivery device provides an actuating force that acts either directly or through a medium to cause a flowable compound to be delivered from the delivery device to the cannula and into the vertebra. The pressure delivery device causes a pressurized compound to be delivered, the pressurized compound may be liquid or gaseous CO | 12-25-2008 |
| 20100137862 | Intramedullary Repair System for Bone Fractures - An intramedullary bone fixation device is disclosed herein. The device includes a first longitudinally extending member, a second longitudinally extending member, and a coupling member. The first longitudinally extending member includes a connector end and a bone engagement end opposite the connector end. The second longitudinally extending member includes a connector end and a bone engagement end opposite the connector end. The coupling member is configured to engage the connector ends of the respective longitudinally extending members, thereby coupling the first longitudinally extending member to the second longitudinally extending member. The device may be provided in an kit form at least partially unassembled. The device may be delivered into a fracture and fully assembled within the fracture or adjacent bone via percutaneous or minimally invasive surgical procedures. The device, on account of its configuration and assembly, may be considered modular in some cases. | 06-03-2010 |
| 20100137987 | Intramedullary Repair System for Vertebra Fractures - An system for reducing a fracture in an vertebral body is disclosed herein. The system may include incremental implant elements and a delivery device. The incremental implant elements are configured for percutaneous delivery into, and accumulation within, a volume of the vertebral body. The delivery device is configured to percutaneously deliver the incremental implant elements into the volume of the vertebra body in an incremental fashion. As the incremental implant elements are incrementally delivered into the volume of the vertebra body, the accumulation of the incremental members in the volume of the vertebra body places the fracture in the vertebra body in a reduced state. | 06-03-2010 |

| 20110082493 | MEDICAL CLOT TREATMENT DEVICE WITH DISTAL FILTER - This is a surgical device usually delivered through an intravascular catheter. It may be used in several ways. It may, for instance, be used to open a clear passageway adjacent thrombus to allow both blood and medication to bypass the clot. It may be used to pierce and to remove thrombus. These thrombus are often found in tortuous vasculature. The device includes several sections. The device has a core element, typically a core wire. Placed around the distal end of the core element is a collapsible but preferably self expanding proximal cage assembly and a distal filter, preferably a self-expanding cage assembly or other filter component. The various portions of those components are preferably radio-opaque. The proximal end of the proximal cage is typically is affixed to an actuator in such a way as to allow expansion of the cage after deployment. The proximal cage assembly may be used for collecting emboli or for displacing them to allow blood flow to resume, either with or without concurrent clot-dissolving drug treatment. The distal sector, whether a self-expanding cage or fan, is placed distally of the thrombus to collect portions of the thrombus which may loosen during the treatment or removal procedure. | 04-07-2011 |

The apparatus further includes a separator disposed on the outer sheath and adapted to engage the prosthetic segments. The separator is also adapted to be retracted proximally over the prosthetic segments and advanced distally to separate a proximal group of the prosthetic segments from a distal group of the prosthetic segments which are to be deployed in the body lumen. | 05-26-2011 |
| 20110144625 | Composite Braided Guidewire - This is a composite guidewire for use with a catheter for accessing a targeted site in a lumen system of a patient's body. The guidewire core or guidewire section may be of a stainless steel or a high elasticity metal alloy, preferably a Ni—Ti alloy, also preferably having specified physical parameters. The composite guidewire assembly is especially useful for accessing peripheral or soft tissue targets. The invention includes multi-section guidewire assemblies having super-elastic alloy or stainless steel ribbon braided reinforcements along a least a portion of the core. A variation of the inventive guidewire includes a braid and a tie layer (and one or more lubricious polymers on the tie layer exterior) to enhance the guidewire's suitability for use within catheters and within the interior of vascular lumen. | 06-16-2011 |
