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

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 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.

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

Systems and methods for indicating an interval in which a procedure (or sub-procedure) should be carried out are disclosed. Some systems and methods involve timing various sub-procedures and alerting a practitioner at the completion of a sub-procedure period. Some systems and methods include a sensor, such as a temperature sensor, that is used determine a window of time in which a variable-viscosity material is of suitable viscosity for delivery to a patient.

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.

Swivel hub

A medical grasping device is disclosed. The medical grasping device may be configured to retrieve an object from within a body lumen. A medical grasping device assembly, wherein a portion of the medical grasping device is disposed within a lumen of a delivery sheath, and methods of using the medical grasping device assembly are also disclosed.

Medical grasping device

Dilators, such as rapid exchange dilators, configured for percutaneous access are disclosed. The dilator may be configured to be disposable within, or couplable with, a catheter. In some embodiments, the dilator, or the coupled dilator and the catheter, may be configured such that a sheath is not required for percutaneous access. In other embodiments, the dilator may comprise a plug such that a guide wire may be directed from a distal end of the dilator through a port, such as a rapid exchange port, in a sidewall of the dilator. The plug may also be configured to permit passage of fluid through a lumen of the dilator while inhibiting passage of the guide wire through a length of the dilator.
