A method includes inserting an ablation catheter into an ablation site in a patient heart. Multiple electrocardiogram (ECG) signals are acquired. A refractory period of the patient heart is detected based on the acquired ECG signals. The ablation site is ablated using the ablation catheter during the detected refractory period.

An assembly for receiving fluid pharmaceutical waste into a fluid waste receiver includes a fluid receiver body coupled to a fluid receiver cap, and receiving solid pharmaceutical waste into a solid waste receiver includes a solid receiver body coupled to a solid receiver cap. The assembly comprises a receiver housing and a receiver lid coupled to the receiver housing. The receiver housing comprises a retainer base, sidewalls extending from the retainer base, and dividers extending from the sidewalls to divide an interior of the receiver housing into a receiver compartment configured to receive the fluid receiver body and the solid receiver body, and a cap compartment. A first of the dividers divides the receiver compartment from a first of the cap compartments configured to receive the fluid receiver cap, and a second one of the dividers divides the receiver compartment from a second of the cap compartments configured to receive the solid receiver cap.

Various forms are directed to a method for operating an ultrasonic surgical instrument. The ultrasonic surgical instrument may be activated by generating a drive signal provided to the ultrasonic drive system to drive the end effector. A plurality of input variables may be applied to a multi-variable model to generate a multi-variable model output, where the multi-variable model output corresponds to an effect of the ultrasonic instrument on tissue. The plurality of input variables may comprise at least one variable describing the drive signal and at least one variable describing a property of the ultrasonic surgical instrument. When the multi-variable model output reaches a threshold value, feedback may be generated indicating a corresponding state of at least one of the ultrasonic surgical instrument and tissue acted upon by the ultrasonic surgical instrument.

According to an aspect of some embodiments of the present invention there is provided a method of dynamically adapting a facial treatment based on a current facial skin profile, comprising: using at least one sensor for measuring at least one current value of at least one variable skin characteristic of facial skin of a patient; acquiring at least one personal skin characteristic of facial skin of the patient; calculating a current facial skin status of the patient according to the at least one personal skin characteristic and the at least one current value; determining instructions to operate a treatment applicator according to the current facial skin status; and instructing the treatment applicator according to the instructions.

A surgical instrument comprising a handle, a shaft rotatable relative to the handle, and an end effector articulatable relative to the shaft about an articulation joint is disclosed. The shaft comprises a grip and at least one articulation control on the grip.

Systems, devices and methods manage surgical instruments throughout their lifecycle by reprogramming a device to account for operational displacement of ultrasonic components based upon a diagnostic test. A diagnostic test tip is used with a surgical instrument to simulate device usage and capture capacitance and phase margin of the device. This information is used to calculate an optimal current to supply to the device during future procedures.

Methods, devices, and systems establish and facilitate retrograde or reverse flow blood circulation in the region of the carotid artery bifurcation in order to limit or prevent the release of emboli into the cerebral vasculature such as nto the internal carotid artery. The methods are particularly useful for interventional procedures, such as stenting and angioplasty, atherectomy performed through a transcarotid approach or transfemoral into the common carotid artery, either using an open surgical technique or using a percutaneous technique, such as a modified Seldinger technique or a micropuncture technique.

A control system for a surgical instrument. The control system comprises an RFID scanner and a control circuit coupled to the RFID scanner. The control circuit is configured to receive data from RFID tags associated with devices, determine whether the devices are compatible based on a comparison of the received data, and provide an alert that the devices are incompatible or a suggestion to replace one of the devices with a replacement compatible device.

Provided is a tourniquet device including a belt body and a timer, wherein the timer includes: a housing having a plurality of bulges; a connecting component arranged on the outside of the housing to connect the belt body to the timer; and a timing unit and a warning unit, which are arranged inside the housing, wherein the belt body is clamped between the bulges and the connecting component. In the tourniquet device, the timer is small, simple to operate, and not easy to fall off from the belt body. In addition, the tourniquet device is suitable for users' conventional operation without undue difficulties in use.

A working end of a catheter includes at least one therapeutic element, such as a resistive heating element, usable to deliver energy for ligating, or reducing the diameter of, a hollow anatomical structure. In certain examples, the catheter includes a lumen to accommodate a guide wire or to allow fluid delivery. In certain embodiments, a balloon is inflated to place resistive element(s) into apposition with a hollow anatomical structure and to occlude the structure. Indexing devices and methods are also disclosed for successively treating portions of the hollow anatomical structure. In certain examples, marks along the catheter shaft provide visual verification to the physician of the relative position of the therapeutic element of the catheter. Embodiments of indexing devices may include pairs of rings and/or hinged arms that move a catheter a desired indexed position between successive treatments.
