A hemostatic sealer includes a handle having a switch to activate a source of thermal energy and a thermal assembly coupled to the handle. The thermal assembly includes an electrically resistive material disposed on an electrically insulative substrate. The resistive material is coupled to the switch to receive the source of thermal energy.

A portable drain system having a subdermal drain and a container in fluid communication with the subdermal drain is disclosed. The subdermal drain is configured to drain fluid from a surgical site. The container provides a negative pressure to the subdermal drain. The container draws and receives the fluid. The container includes at least one sensor in which the at least one sensor is configured to detect at least one of fluid color, fluid volume in the container, and orientation of the container.

Surgical drain system and container

A container for a portable surgical drain system to receive a fluid from a drain at a surgical site is disclosed. The container includes a drain hub having at least one sensor and a cartridge removably coupled to the drain hub in fluid communication with the drain to provide a suction source to draw and receive the fluid from the surgical site. The at least one sensor detects a characteristic of the fluid in the cartridge.

An electrosurgical device includes a handpiece, an electrode tip extending from the handpiece, the electrode tip configured to deliver an RF signal, and a multivariate controller disposed on the handpiece. The multivariate controller is configured to activate the electrode tip and adjust a setting of the RF signal within a range of settings.

Electrosurgical device with multivariate control

An electrosurgical hand piece device is configured to cut tissue with monopolar RF energy to extract a medical lead submersed in fluid. The device includes an electrode surrounded by an electrically insulating coating that can be exposed from a distal edge of the electrode when power is supplied to the device, thereby focusing the energy at the distal edge and enabling tissue to be more easily and safely cut from around the medical lead while in fluid.

Device for medical lead extraction

A tissue expansion device with a plurality of lobes made from non-compliant material, each lobe defining a chamber therein. Each chamber is fluidly isolated from every other chamber in the plurality of lobes. Each chamber has an inflation element with a valve to release a pressurized fluid to inflate the lobe to expand a cavity, and a deflation element with a valve to deflate the lobe by compressing the fluid.
