| 20090112249 | MEDICAL DEVICE FOR MODIFICATION OF LEFT ATRIAL APPENDAGE AND RELATED SYSTEMS AND METHODS - Several embodiments are set forth of devices, systems and methods for modifying an atrial appendage such as a left atrial appendage (LAA). In one embodiment, a device includes a body that is collapsible and self-expanding. The body includes a textured surface with protruding portions and recessed portions. The body may be formed of a reticulated foam material and may exhibit a substantially spherical geometry or a truncated spherical geometry. The body may be substantially hollow. In one embodiment, portions of the textured surface may be metalized or have a coating placed thereon to enhance frictional engagement of the body with the atrial appendage wall. In another embodiment, a mesh bag is disposed within an LAA and one or more self-expanding bodies are disposed within the mesh bag. The mesh bag is then secured to retain the self-expanding bodies within the bag and the LAA. | 04-30-2009 |
| 20100006105 | APPARATUS AND METHODS FOR OCCLUDING A FALLOPIAN TUBE - The present invention is directed to various embodiments of medical devices and methods for occluding a fallopian tube for contraception and permanent sterilization. In one embodiment, the medical device includes an outer member, an inner member and a tissue growth member. The outer member includes an outer surface and an inner surface, wherein the inner surface defines a bore in the outer member. The inner member is configured to be positioned within the bore of the outer member. The tissue growth member is attached to the outer surface of the outer member and is configured to induce tissue growth thereto. With this arrangement, the medical device can be implanted within the fallopian tube and serve as a permanent occluding device therein. If desired, the medical device can be partially removed from the fallopian tube to restore the ability for conception. | 01-14-2010 |
| 20100324595 | DEVICES FOR REDUCING THE SIZE OF AN INTERNAL TISSUE OPENING - A medical system for treating an internal tissue opening can include a closure device and associated delivery device. The closure device can include a body portion operatively associated with a first anchor and a second anchor. The body portion can include a plurality of segments defining a multi-cellular structure. The closure device can be configured to apply lateral force to tissue of the internal tissue opening to bring tissue together. The closure device can have a substantially flat aspect, and have a depth thickness that is substantially greater than the thickness or width of a majority of the members forming the closure device to reduce out of plane bending. The closure device can also include a member adapted to induce tissue growth. | 12-23-2010 |

| 20080211290 | Tapered Bore in a Pick - In one aspect of the present invention, a high impact resistant excavation pick having a super hard material is bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide frustum. A tapered bore is formed in the base end of the carbide frustum opposite the front end and a steel shank with a tapered interface is fitted into the tapered bore. | 09-04-2008 |
| 20080223569 | Centering assembly for an electric downhole connection - A downhole tool string component having a tubular body having a bore with a central longitudinal axis. An electrical conductor assembly is disposed within the bore of the tubular component, the assembly having signal couplers at first and second ends adapted for a butt connection. Centering assemblies are disposed within each end of the bore and have a plurality of projections extending radially outward from at least a partial central ring disposed around a portion of each end of the electrical conductor assembly, at least one centering assembly comprising a radial opening in the central ring adapted to receive the electrical conductor assembly. The first and second ends of the electrical conductor assembly are substantially aligned to the central axis of the bore at each end by the centering assemblies, the centering assemblies being adapted to allow fluid to pass through the bore. | 09-18-2008 |
| 20090025942 | Borehole Liner - A system for forming a liner downhole within a well bore has a rig comprising a tool string driving mechanism and an aperture proximate an opening of a well bore. The system also has first and second tool string components and each component has a central bore disposed intermediate first and second tool joints of the component. The first tool joint of the first component is disposed proximate the aperture and the second tool joint of the second component. First and second resilient lining materials are disposed within the central bore of the first and second tool string components respectively. At least one lining material connecting mechanism is disposed proximate the aperture. The system also comprises at least one downhole dispenser that is adapted to direct a resilient continuous lining material against the well bore to form a liner. | 01-29-2009 |
| 20090133938 | Thermally Stable Pointed Diamond with Increased Impact Resistance - In one aspect of the present invention, an insert comprises a sintered polycrystalline diamond body bonded to a cemented metal carbide substrate. The diamond body comprises a substantially conical shape with conical side wall terminating at an apex. The diamond body comprises a first region with a metallic catalyst dispersed through interstices between the diamond grains and a second region proximate the apex with the characteristic of higher thermal stability than the first region. | 05-28-2009 |
| 20090260894 | Jack Element for a Drill Bit - In one aspect of the present invention, a drill bit has an axis of rotation and a working face with a plurality of blades extending outwardly from a bit body. The blades form in part an inverted conical region, and a plurality of cutters with a cutting surface is arrayed along the blades. A jack element is coaxial with the axis of rotation and extends within the conical region within a range defined by the cutting surface of at least one cutter. | 10-22-2009 |
| 20110048811 | DRILL BIT WITH A RETAINED JACK ELEMENT - A drill bit having a bit body intermediate a shank and a working face having at least one cutting insert. A bore is formed in the working face co-axial within an axis of rotation of the drill bit. A jack element is retained within the bore by a retaining element that intrudes a diameter of the bore. | 03-03-2011 |
