Patent number: 11224475Abstract: 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.Type: GrantFiled: October 22, 2019Date of Patent: January 18, 2022Assignee: MEDTRONIC HOLDING COMPANY SÀRLInventors: Neil Godara, Jason Woo, Emily Won

Patent number: 11213339Abstract: Flexible apparatus for ablating unhealthy spinal tissue. A housing includes a distal end and a proximal end. Multiple thermocouples mounted on the housing measure spinal tissue temperatures at locations between the proximal end and the distal end. A sensor measures spinal tissue impedance. The measured spinal tissue impedance corresponds to various physical state data of the spinal tissue. The spinal tissue impedance and the spinal tissue temperatures are displayed to the surgeon, enabling the surgeon to determine with certainty the location of the unhealthy spinal tissue, and to exercise control over the ablation apparatus. Nerve stimulation by IMP/STM switch system to detect nerve responses before and after treatment.Type: GrantFiled: July 29, 2019Date of Patent: January 4, 2022Assignee: MEDTRONIC HOLDING COMPANY SÀRLInventors: Stephen W.

Publication number: 20210315623Abstract: A method of treating a bone of a patient includes identifying a portion of the patient to be protected. A cannula is provided that includes a shaft extending between opposite first and second end surfaces. The shaft incudes an inner surface defining a lumen. The cannula includes a scoop extending from the second end surface. The scoop includes an inner surface that is continuous with the inner surface of the shaft and an opposite outer surface. The cannula is inserted into the bone such that the outer surface of the scoop is positioned adjacent to the portion of the patient to be protected. A balloon is inserted into the cannula such that the balloon is positioned within the scoop. The balloon is inflated such that the balloon expands away from the scoop as the balloon is inflated and creates a void in the bone.

Publication number: 20210228251Abstract: An inflatable bone tamp for performing a minimally invasive surgical procedure includes an outer shaft defining an internal lumen, an inflatable structure coupled to the outer shaft, and an inner shaft movably disposed within the internal lumen and coupled to a distal end region of the inflatable structure. The internal lumen is sized to receive the inflatable structure, such that by moving the inner shaft relative to the outer shaft, the inflatable structure can be retracted into the internal lumen (and likewise can be extended from within the internal lumen for deployment in bone). This retraction capability can beneficially protect the inflatable structure during positioning/removal, and can also enhance recovery from radial tears of the inflatable structure.Type: ApplicationFiled: April 14, 2021Publication date: July 29, 2021Applicant: MEDTRONIC HOLDING COMPANY SÀRLInventors: Calin Druma, Bruce Chabansky

Publication number: 20200305941Abstract: 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: May 20, 2020Publication date: October 1, 2020Applicant: MEDTRONIC HOLDING COMPANY SÀRLInventor: BRADLEY E.

Patent number: 10729490Abstract: A method and apparatus for treating tissue are disclosed, including intra-operative mapping of a probe ablation zone. The method uses a system that maps the proximal and distal margins of the probe ablation zone using tools that access the ablation target. In some embodiments, the tools comprise a bone drill, and an introducer assembly, including a cannula and a stylet. The tools have features or markings that cooperate to indicate which probe to use to achieve the desired ablation. The method further facilitates planning probe placement for delivering energy to treat (ablate) a desired ablation volume of a target tissue by using a system that maps both the target tissue and possible probe ablation zones.Type: GrantFiled: September 14, 2015Date of Patent: August 4, 2020Assignee: Medtronic Holding Company SàrlInventors: Neil Godara, Jason Woo, Terence Cheong
