  • Patent number: 10159518
    Abstract: A flexible obturator configured to dilate soft tissue without abrading the adjacent bone surface area. The flexible obturator consists of at least one flexible strand (for example, flexible wire, suture or similar malleable flexible material) that is overmolded with a material that allows the device to bend/flex in multiple planes. The overmolded material has an increasing taper to provide graduated dilation through soft tissue.

  • Patent number: 10066444
    Abstract: Method of operating earth-boring tools may involve activating a selectively activatable hydraulic fracturing device secured to the earth-boring tool to impact an underlying earth formation with a fluid from the selectively activatable hydraulic fracturing device. A crack may be at least one of initiated or propagated in a portion of the underlying earth formation utilizing the fluid in response to activation of the selectively activatable hydraulic fracturing device. The selectively activatable hydraulic fracturing device may be subsequently deactivated. Earth-boring tools may include a selectively activatable hydraulic fracturing device configured to transition between an activated state in which fluid is permitted to flow through the selectively activatable hydraulic fracturing device to engage with an underlying earth formation and a deactivated state in which fluid does not flow through the selectively activatable hydraulic fracturing device.

  • Patent number: 10005158
    Abstract: A method of forming an earth-boring tool includes forming a tool body including at least one inverted cutting element pocket, at least a portion of the at least one inverted cutting element pocket having a profile substantially matching a profile of an actual cutting element to be secured within a cutting element pocket to be formed by subsequently machining the at least one inverted cutting element pocket. Hardfacing material may be applied to portions of the tool body. The actual cutting element pocket is formed by removing material of the tool body within the at least one inverted cutting element pocket subsequent to applying the hardfacing material to portions of the tool body. A cutting element is affixed within the actual cutting element pocket.

  • Patent number: 9855029
    Abstract: A method of fixating soft tissue to bone using a bone anchor connected to a construct formed of a suture strand passing through the anchor and a shuttle device passing through a splice region of the suture strand. After installing the anchor in bone, an end of the suture strand is passed around or through soft tissue to be fixated, and then the end of the suture strand is inserted into an eyelet of the shuttling device. By pulling on the opposite end of the shuttling device, the end of the suture strand is passed through the splice region of the flexible strand, thereby forming a knotless closed loop having an adjustable perimeter. As the loop is tightened, the soft tissue is tensioned against the bone.

  • Publication number: 20170252033
    Abstract: Systems and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair systems include self-cinching constructs with a fixation device, a flexible construct having a flexible strand abutting a suture tape, and a shuttle/pull device attached to the flexible strand and provided within the body of the fixation device. A splice is formed by pulling on the shuttle/pull device subsequent to the fixation device being secured into the bone, to allow the wide tape to be positioned over the tissue (for best compression and minimum tissue cut-thru) and suture for the implanted portion (for most efficient and least bone removal).

  • Patent number: 9737787
    Abstract: A binding strap assist mechanism. The binding strap assist mechanism can be retrofitted onto standard snowboard binding straps to bias the binding straps into the open configuration, thus guiding the straps way from the foot area of the binding. Binding straps pass through the binding strap assist mechanism so that tensile forces along the length of each of these binding straps during use is not significantly conveyed to the binding straps assist mechanism. The tensile forces are thus isolated to the binding straps which are intended to carry such forces. The present invention provides a safe and convenient feature to snowboard bindings and other bindings. If the binding strap assist mechanism breaks or fails to function, the binding straps will continue to function as normal, resulting in no safety concerns to user.

  • Publication number: 20170204674
    Abstract: A tool for forming or servicing a wellbore includes a first body, a second body, and a retaining member located between a surface of the first body and a surface of the second body. The retaining member at least partially retains the second body with respect to the first body. The retaining member comprises a shape memory material configured to transform, responsive to application of a stimulus, from a first solid phase to a second solid phase. A method of forming a tool for forming or servicing a wellbore includes disposing a retaining member comprising a shape memory material in a space between a first body and a second body and transforming the shape memory material from a first solid phase to a second solid phase by application of a stimulus to cause the retaining member to create a mechanical interference.

  • Publication number: 20170204672
    Abstract: An earth-boring tool includes a tool body, at least one cutting element, and a retaining member comprising a shape memory material (e.g., alloy, polymer, etc.) located between a surface of the tool body and a surface of the cutting element. The shape memory material is configured to transform, responsive to application of a stimulus, from a first solid phase to a second solid phase. The retaining member comprises the shape memory material in the second solid phase, and at least partially retains the at least one cutting element adjacent the tool body. The shape memory material may be trained in a first phase to a first shape, and trained in a second phase to a second shape. The retaining member may be at least partially within a cavity in the first phase, then transformed to the second phase to apply a force securing the cutting element to the tool body.

  • Patent number: 9693765
    Abstract: Knotless, adjustable anchor systems that allow for knotless tensioning of tissue (such as the rotator cuff) after anchor implantation. The knotless, adjustable anchor system includes knotless anchors (for example, swivel and/or screw-in suture anchors and/or push-in suture anchors) that are modified to carry a self-locking, adjustable construct (for example, a suture assembly with a spliced suture loop) and to position the self-locking, adjustable construct at the repair site. The system allows for knotless tensioning of the tissue after the knotless anchors have been implanted. The medial row anchors are implanted and passed through tissue in a similar fashion as the current Corkscrew® or SwiveLock® C anchors are. The lateral row anchors are similar to a knotless SutureTak® but modified to accommodate a larger suture to hold a larger load. The suture is interconnected to the medial row and returned back to the lateral row for loading into the splice.
