  • Publication number: 20180325571
    Abstract: The risk of bone cement extravasation can be reduced by delivering a calcium-dependent polymerizing sealant into a bone structure prior to delivery of bone cement into that structure. The polymerization of the sealant in response to the calcium within the bone structure can fill cracks and any other potential cement leakage paths, thereby minimizing the potential for subsequent extravasation. The benefits of the use of a calcium-dependent polymerizing sealant can be provided in any procedure involving the use of bone cement, such as spinal fixation, vertebroplasty, and kyphoplasty, among others.

  • Patent number: 10064672
    Abstract: A valve controller includes a housing, and a lever extending from the housing. The lever includes a protrusion rigidly attached to the lever, and the lever is biased to an initial position. A switch has an open and a closed position. A linkage is pivotally connected to the switch, and the linkage includes a centrally disposed slot configured to receive the protrusion such that movement of the switch controls movement of the linkage and the lever such that moving the switch to the closed position closes a valve controlled by the lever regardless of a position of the lever.

  • Publication number: 20180199977
    Abstract: A surgical instrument includes an outer shaft defining a passageway. An inner shaft is disposed within the passageway and defines a lumen. An expandable structure has a first end coupled to a second end of the outer shaft and a second end coupled to a second end of the inner shaft. The expandable member defines a chamber. A delivery shaft includes a first end positioned within the passageway and a second end positioned within the chamber. The delivery shaft defines a channel configured to deliver a coolant out of an opening in the second end of the delivery shaft and into the chamber to move the expandable structure from an unexpanded configuration to an expanded configuration. A variable exhaust valve is in communication with the passageway and is configured to regulate pressure within the chamber. Systems and methods are disclosed.

  • Patent number: 10005048
    Abstract: A manual mixer serves to facilitate mixing and agitating materials for use during surgery. For example, the manual mixer includes a body portion defining an interior area, a mixing assembly provided in the interior area of the body portion, a crank assembly for actuating the mixing assembly, and a valve assembly. The mixing assembly serves to mix and agitate the materials provided in the interior through rotation of a plunger portion and a spring attached thereto, and through upwards and downwards movement of the plunger portion in the interior area. Rotation of the crank assembly serves to rotate the plunger portion and the spring attached thereto, and effectuate upwards and downwards movement of the plunger portion. The valve assembly can be opened to facilitate dispensing of the materials from the interior area.

  • Publication number: 20180036056
    Abstract: A device and method for treating bone fractures/lesions using an inflatable body is provided. The inflatable body includes a balloon having a substantially flat horizontal surface for quick easy insertion into bone beneath the fracture so as to align misaligned fragments of the fracture and/or to collapsed bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and/or to restore the original position of the outer cortical bone, if fractured or collapsed. The inflatable body has a stylet attached to it's distal end so that once the inflatable body is deflated it can be twisted about the stylet to have a smaller profile so as to be easily withdrawn from the bone.
