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： 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.

摘要： A cooled radio-frequency (RF) ablation probe is provided. The RF ablation probe includes a first tubular portion defining at least part of an internal cavity for circulating coolant through the cooled RF ablation probe; a second tubular portion surrounding the first tubular portion along a first portion of the length of the cooled RF ablation probe; a third tubular portion surrounding the second tubular portion along a second portion of the length of the cooled RF ablation probe; and a fourth tubular portion surrounding the third tubular portion along a third portion of the length of the cooled RF ablation probe. A gap is defined between the third tubular portion and the fourth tubular portion that can be filled with air or a vacuum can be formed in the gap to insulate one or more thermocouples attached to the fourth tubular portion from the coolant in the internal cavity.

摘要： An inflatable bone tamp is provided that includes a shaft defining a lumen. A balloon is coupled to the shaft such that a material can flow through the lumen and into the balloon to inflate the balloon. A connector is coupled to the shaft. The connector includes a first port and a second port. The ports are in communication with the lumen. A flow control device is coupled to the first port. The flow control device controls flow of the material through the first port and into the lumen. A damper is coupled to the second port. The damper controls pressure within the inflatable bone tamp when pressure within the inflatable bone tamp reaches a threshold. Kits, systems and methods are disclosed.

摘要： A adaptor is used with a driver, a drill, and a cannula to facilitate removal of material from bone and placement of the cannula in the bone. The adaptor includes an end portion provided at a proximal first end that is configured to engage a portion of the drill; a body portion attached to the end portion and extending from the end portion toward a distal second end; a head portion provided at the distal second end and attached to the body portion; and a passageway for receiving the drill that extends through the adaptor. Furthermore, the head portion includes a distal surface and at least one coupler provided on or adjacent the distal surface for releasably engaging. the cannula.

摘要： An inflatable bone tamp is provided that includes a shaft with proximal and distal portions and a central longitudinal axis. A balloon is attached to the shaft such that a material can flow through the shaft and into the balloon to inflate the balloon. A flow controller controls the flow of the material through the shaft and into the balloon. Kits, systems and methods are disclosed.

摘要： An access and radio-frequency (RF) ablation system and method for use thereof is provided. The access and RF ablation system can include an RF ablation probe, a stylet, a cannula, a needle, and a drill. The method of using the access and radio-frequency ablation system can include inserting portions of a combined stylet into a patient's body to create a pathway therethrough and position a distal end of the stylet and a distal end of the cannula adjacent hard and/or soft tissues requiring ablation or tissues adjacent thereto; pushing portions of the needle into, through, and out of an interior cavity of the cannula to position a curved distal end of the needle adjacent the distal end of the cannula in the pathway; lengthening the pathway in an angled and curved direction relative to a mid-longitudinal axis of the cannula by pushing the curved distal end portion of the needle further into the hard and/or soft tissues requiring ablation or the tissues adjacent thereto; guiding a drill using the needle to enlarge and/or further lengthen the pathway in the hard and/or soft tissues requiring ablation or the tissues adjacent thereto in an angled and curved direction relative to the mid-longitudinal axis of the cannula; pushing portions of the RF ablation probe into, through, and out of the cannula and into and through the pathway to position a distal end portion of the RF ablation probe adjacent the hard and/or soft tissues requiring ablation; and activating the RF ablation probe to ablate all or portions of the hard and/or soft tissues requiring ablation.

摘要： A deployable radio-frequency (RF) ablation needle is provided. The deployable RF ablation needle is used to apply RF energy to hard and/or soft tissues to facilitate ablation thereof. Portions of the deployable RF ablation needle are configured for expansion from an undeployed configuration to a partially or completely deployed configuration via actuation by a user. The undeployed configuration of these portions of the deployable RF ablation needle affords a relatively small insertion size to facilitate insertion thereof into the hard and/or soft tissues, and the expansion of these portions from the undeployed configuration to the partially or completely deployed configuration correspondingly increases the application area of the RF energy to correspondingly increase the ablation zone afforded by use thereof.
