摘要： Devices, and methods of use thereof, are disclosed for preventing tumor seeding when withdrawing the device along an entry-exit path. Some embodiments of the present invention comprise a method of withdrawing a probe through a tissue via a path that traverses at least some bone tissue, the method including withdrawing the probe through the path, and at least partially concurrently delivering energy in a bipolar manner from the probe to heat a layer of tissue surrounding the probe to a temperature sufficient for thermal coagulation necrosis of cells. The device may be withdrawn incrementally.

摘要： An inflatable bone tamp including a first balloon portion and a second balloon portion is provided. Each of the first balloon portion and the second balloon portion include interior cavities that can be filled with liquid, and these interior cavities communicate with one another via a valve. The valve can limit or restrict flow of the liquid between the cavities. As such, the first balloon portion and the second balloon portion can be sequentially inflated with the liquid through use of the valve.

摘要： A dispensing system includes a device having a body extending along a longitudinal axis between opposite 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 extending through the wall and comprising a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Wherein pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a material within the proximal chamber out of the first port and the distal plunger moves a material within the distal chamber out of the second port. Kits and methods of use are disclosed.

摘要： An inflatable bone tamp includes an outer shaft defining a passageway. An inner shaft is positioned within the passageway. The inner shaft defines a lumen. A balloon has a first end coupled to the outer shaft and a second end coupled to the inner shaft such that material can flow through the lumen and into the balloon and exit the balloon through a channel between the inner and outer shafts. A valve is positioned within the channel. The valve is configured to move from a closed orientation in which the valve blocks the channel and an open orientation in which the does not block the channel. Kits, systems and methods are disclosed.

摘要： An electrosurgical probe with internal cooling for use in systems and methods for lesioning in bone and other tissue is disclosed. The probe includes a distal electrical insulator, a proximal electrical insulator, a distal electrical conductor defining a distal electrode with a closed distal end and a proximal electrical conductor defining a proximal electrode, the distal electrode longitudinally spaced apart and electrically isolated from the proximal electrode by the distal electrical insulator. The distal electrode has a closed proximal end formed by a distal face of the distal electrical insulator to thereby define a closed distal inner lumen for circulating the cooling fluid. The proximal electrode has a closed distal end formed by a proximal face of the distal electrical insulator and a closed proximal end formed by a distal face of the proximal electrical insulator to thereby define a closed proximal inner lumen for circulating the cooling fluid.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： An inflatable bone tamp for performing a minimally invasive surgical procedure includes a shaft having a primary region and a reduced diameter region, and an inflatable structure surrounding at least a portion of the reduced diameter region. The reduced diameter region of the shaft allows the deflated size of the inflatable structure to be minimized, while at the same time eliminating the need for the conventional dual lumen balloon catheter construction.
