Device/system that provides pain relief by delivering stimulation that neither generates action potentials nor completely blocks neural transmission (in the peripheral nerve). The present teachings provide relief by modulating release of neurotransmitters in peripheral nerves to cause neuromodulation at the level of the peripheral nerve (modulation of neural signals in the peripheral nerve). The present teachings provide relief by modulating release of neurotransmitters in peripheral nerves to cause neuromodulation at the level of the peripheral nerve (modulation of neural signals in the peripheral nerve) to alter the frequency of physiologically generated neural transmission.

An electric device for skin treatment, includes: a needle body including needles for drug injection and electrical stimulation treatment and a needle printed circuit board (PCB) connected to the needles; a needle cap provided at a first end of the needle body and having a needle hole through which the needles passes; and a handpiece body having a first end detachably connected to a second end of the needle body. The handpiece body includes: a connection PCB to which a connection member configured to be electrically connected to the needle PCB is coupled; and a connection PCB cable configured to be electrically connected to the connection PCB.

A neurostimulation system is disclosed for providing treatment to a patient during a therapy session. The neurostimulation system includes a neurostimulator for transmitting magnetic or electrical signals based upon a treatment program. A programmer is connected to the neurostimulator to set a treatment session parameter value to calculate a therapy compliance value. A compliance module is connected to the neurostimulator and the programmer to calculate and store a therapy compliance value. A control module is connected to the compliance module, the programmer and the neurostimulator and determines whether the therapy compliance value is within a range of the treatment program. The neurostimulator transmits electrical or magnetic signals to the patient in a treatment session only if the therapy compliance value meets a compliance criteria.

Systems and methods for delivering a drug or other therapy over an extended period of time (e.g., several hours, days, weeks, months, years, and so forth) are disclosed herein, as are systems and methods for monitoring various parameters associated with the treatment of a patient. Systems and methods are also disclosed herein that generally involve CED devices with various features for reducing or preventing backflow.

A retractor apparatus for a surgical robotic system includes a frame defining a central open region, a connecting member that connects the frame to a robotic arm, a plurality of coupling mechanisms for attaching a set of retractor blades within the central open region of the frame such that blades define a working channel interior of the blades, and a plurality of actuators extending between the frame and each of the coupling mechanisms and configured to move the blades with respect to the frame to vary a dimension of the working channel. Further embodiments include a surgical robotic system that includes a robotic arm and a retractor apparatus attached to the robotic arm, and methods for performing a robot-assisted surgical procedure using a retractor apparatus attached to a robotic arm.

The present application relates to a cannula, comprising a cannula body with a cannula tube and a body part attached to the proximal end of the cannula tube, a control clip having a mounting body with at least one control element, said control clip being attachable laterally on the body part to form a first configuration. In addition, the present applications relates to a cannula body, a contact clip and a control clip of a cannula.

A neuromodulation system includes a conductive element, a magnetic field generator, a power module and a computer processor. The conductive element located internal a patient's body. At least a portion of the conductive element is positioned adjacent to a target tissue. The magnetic field generator is positioned external to the patient's body. The magnetic field generator generates a time varying magnetic field for inducing stimulation of the target tissue in combination with the conductive element to produce stimulation that is larger than that which would occur in the absence of the conductive element. The power module supplies power to the magnetic field generator. The computer processor controls the time varying magnetic field provided by the magnetic field generator according to at least one set of stimulation parameters.

A treatment apparatus includes a motorized subsystem in a handpiece housing having a rotating output shaft, an axial cam driven in rotation by the output shaft, and a push rod linearly driven by the axial cam. A cartridge is removably attachable to the handpiece housing and includes a cartridge housing, a needle assembly, a piston in the housing engaging the needle assembly and linearly driven forward by the push rod, and a first biasing member urging the piston rearward.

A chest tube device with neurostimulation is provided, along with a method of electrically stimulating at least one of (i) one or more peripheral nerves and (ii) one or more nerve fibers of a thoracic region of a patient, to mitigate pain in patients undergoing chest tube implantation. The chest tube device includes a tubular member and an electro-analgesic region to provide neurostimulation to one or more peripheral nerves and/or nerve fibers of the thoracic region of the patient. The method includes electrically stimulating one or more peripheral nerves and/or nerve fibers of the thoracic region of the patient, and hyperpolarizing the one or more peripheral nerves and/or nerve fibers of the thoracic region to (i) reduce an amount of pain signals from being transmitted to the brain of the patient and/or (ii) prevent pain signals from being transmitted to the brain of the patient.
