Spinal tumor ablation devices and related systems and methods are disclosed. Some spinal tumor ablation devices include electrodes that are fixedly offset from one another. Some spinal tumor ablation devices include a thermal energy delivery probe that has at least one temperature sensor coupled thereto. The position of the at least one temperature sensor relative to other components of the spinal tumor ablation device may be controlled by adjusting the position of the thermal energy delivery probe in some spinal tumor ablation devices. Some spinal tumor ablation devices are configured to facilitate the delivery of a cement through a utility channel of the device.

Tumor ablation devices and related methods

An self-actuating grasping device and corresponding method of using the grasping device for retrieving a foreign object from a location in a patient's body. The grasping device has a handle with a self-actuating mechanism, an actuator on the handle coupled to an actuator wire, an elongated shaft member extending distally from the handle with the actuation wire coaxially disposed therein and opposing jaws at a distal end of the elongated shaft member that are coupled to the actuation wire and pivot between open and closed configurations. The self-actuating mechanism has a bias that imparts a closing force to the opposing jaws through the actuation wire. Actuation of the actuator is configured to impart an opening force to the opposing jaws through the actuation wire.

Self-actuating grasping device

Devices used to pressurize, depressurize, or otherwise displace fluid are disclosed. The devices may be configured to displace fluid in order to inflate or deflate a medical device, such as a balloon. The devices include a trigger configured to convert the devices from a pressurization state to a priming state. The devices further include a locking or toggle member configured to toggle and/or maintain the devices in a priming state.

Inflation device with toggle-locking trigger

Devices and methods for acquiring and fastening tissues folds within an internal organ, such as the stomach, and for applying the methods and devices to producing reductions in organ volume or repair of bariatric procedures, are disclosed. An exemplary method for forming a continuous laterally extending tissue fold involves forming a succession of laterally extending folds having adjacent overlapping fold portions. One exemplary tissue-acquisition device has an open-end roller-and-arm structure that allows individual tissue folds to be formed and fastened, then advanced to an adjacent region within the stomach, for capture of a new fold that will form an extension of the existing fold(s).

Tissue-acquisition and fastening devices and methods

The invention relates to a magnetic-navigation joint type puncture needle which comprises a head section and needle sections, wherein, the head section is made of stainless steel material with high magnetic conductivity and is connected with the following needle sections coaxially mounted with the head section through a flexible joint; two needle sections are also coaxially connected with each other through a flexible joint; the needle sections are made of non-magnetic stainless steel material; the flexible joints adopts serpentine tubes formed by melting and engraving cobalt-chromium alloy through laser; and both the head section and the needle sections can be bent, but the flexibility of the head section and that of the needle sections are smaller than the flexibility of the flexible joints. According to the invention, an extra magnetic field force is used to cause the head section of the needle to deflect, so that the following purposes can be achieved that the insertion direction of the needle can be changed, and the other needle sections also deflect with the deflection of the head section; accurate navigation for and control over puncture path and puncture position when the puncture needle performs a non-direct channel puncture in a human body; the puncture needle provided by the invention can reach niduses which other types of puncture needles can not reach; the application scope of minimally invasive surgery is expanded; iatrogenic injuries can be reduced; and patients can be benefited.

Ablation systems with parameter-based modulation and related devices and methods

Medical devices for creating or expanding a cavity within bone of a patient are disclosed. In some circumstances, a medical device, such as an osteotome is designed to facilitate simultaneous advancement and articulation of a distal portion of the osteotome. Simultaneous advancement and articulation of the distal portion may reduce one or more forces on the distal portion of the osteotome relative to other methods in which advancement and articulation are separated in time, thereby decreasing the risk of breakage or other damage to the osteotome.

Osteotome with a distal portion for simultaneous advancement and articulation

Medical devices such as osteotomes are provided. The medical device may include inner and outer members that form a working end portion. Distal end portions of the inner and outer members can cooperate to allow deflection of the working end portion. Medical devices including indicators are also provided. The indicator may communicate a direction of deflection of the working end portion to a practitioner. Additionally, medical devices including torque release mechanisms are provided. The torque release mechanism may uncouple a first portion of the medical device from a second portion of the medical device when an amount of torque applied to the medical device exceeds a predetermined value. The torque release mechanism may limit damage to components of the medical device during use of the medical device.

Medical devices for treating hard tissues and related methods

Tumor ablation devices and related systems and methods are disclosed. Some tumor ablation devices include an RF energy delivery probe with two conductors and one or more thermocouples. The thermocouple measures a temperature at a location on one of the conductors. A generator can produce a current to be conducted between the first conductor and the second conductor via tissue within a desired ablation region. The ablation regions created by the RF energy delivery probe are symmetric about poles of the first conductor and the second conductor. A distal portion of the RF energy delivery probe may articulate, enabling a user to position the RF energy delivery probe in a proper position to ablate the tumor. The thermocouples may be disposed on a flexible or wired thermocouple circuit that is disposed between insulators.

Tumor ablation device and related systems and methods

The present disclosure illustrates an osteotome for treating hard tissue and methods of use. The osteotome embodiments described herein include a shaft with a working end configured to displace hard tissue and a lumen to deliver material through the shaft. The working end may create pathways by selectively transitioning from a linear to a non-linear configuration. The lumen may deliver material through the shaft while the working end is in a linear or a non-linear configuration allowing precise filling of the pathways.

Articulating osteotome with cement delivery channel and method of use

The present disclosure relates to systems and methods for mixing and injecting fluid treatment, such as cement to treat bone or hard tissue. In some embodiments, a mixing apparatus may facilitate mixing within a syringe. Additionally, the syringe may be configured to extract bone cement from a cement mixer. A syringe for mixing and injecting cement may include a detachable handle that may be detached after extracting bone cement from a mixer to facilitate coupling to a high-pressure syringe for injection.

Cement mixing and injection system and methods

Devices used to pressurize, depressurize, or otherwise displace fluid are disclosed. The devices may be configured as a syringe. The syringe may be configured to generate high-pressure within the syringe to inflate or deflate a medical device, such as a balloon, or to inject a substance, such as bone cement, into a bone, such as a vertebra. The syringe may include a pressure reduction mechanism used to depressurize the syringe.

High-pressure syringe with pressure reduction

The present disclosure relates to a connector for medical devices. The connector may have two interfaces facing different planes. The two interfaces may provide access to the connector's core and hub. The hub may be free to rotate relative to the core to increase accessibility and/or angle attachment while maintaining a fluid pathway between the core and the hub.
