Patent number: 11794157Abstract: A system for bone cement includes a vial holder configured for receiving a vial and including a holding structure for maintaining the vial in the vial holder. The vial includes a monomer component for bone cement. A holder chamber is configured to receive and secure the vial holder. The vial holder is advanced toward a vial-breaking device for breaking the vial and releasing its contents into the holder chamber past the elastomeric seal. Once the vial holder is advanced further the elastomeric seal is deformed to form a seal and prevent fumes produced from escaping from the device.Type: GrantFiled: April 9, 2020Date of Patent: October 24, 2023Assignee: KYPHON SARLInventors: Neil S.

Patent number: 11045240Abstract: A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.Type: GrantFiled: June 11, 2019Date of Patent: June 29, 2021Assignee: KYPHON SARLInventors: Neil Sasaki, Amy L. Arthur, Samuel V. Bolosan

Patent number: 10959765Abstract: A medical balloon device includes an outer member extending along an axis. An inflatable member has a proximal end extending from a first end of the outer member and a distal end. An inner member is positioned within the outer member and the inflatable member such that a first end of the inner member is coupled to the distal end of the inflatable member. A support member is movably disposed within the inner member and includes a first end configured to removably engage the first end of the inner member. Translation of the support member along the axis causes the inflatable member to move between a first position in which the inflatable member has a first length and a first profile and a second position in which the inflatable member has a second reduced length and a second reduced profile. Methods of use are disclosed.Type: GrantFiled: July 14, 2017Date of Patent: March 30, 2021Assignee: KYPHON SARLInventors: Bryan J. Auyoung, Warren C. Sapida

Publication number: 20180325571Abstract: 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.Type: ApplicationFiled: July 20, 2018Publication date: November 15, 2018Applicant: KYPHON SARLInventor: Bradley E. Steele

Patent number: 10064672Abstract: 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.Type: GrantFiled: January 25, 2018Date of Patent: September 4, 2018Assignee: Kyphon SÀRLInventor: Brian W.

Publication number: 20180199977Abstract: 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.Type: ApplicationFiled: March 14, 2018Publication date: July 19, 2018Applicant: Kyphon SARLInventor: Stephen Nash

Patent number: 10005048Abstract: 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.Type: GrantFiled: October 3, 2017Date of Patent: June 26, 2018Assignee: Kyphon SÀRLInventor: Neil S.
