Abstract: A medical device includes a sheath extending longitudinally from a proximal end to a distal end and a handle coupled to the proximal end of the sheath. The handle includes a deflection lever coupled thereto. The deflection lever is rotatable proximally and distally along the handle to deflect a distal end of the shaft to which it is operably coupled and a locking mechanism movable between an locked configuration in which the locking mechanism engages an engagement feature on the outer surface of the handle, preventing the deflection lever from rotating and locking the distal end of the shaft in a desired position, and an unlocked configuration in which the locking mechanism releases the engagement feature to allow rotation of the deflection lever and deflection of the distal end of the shaft.

Abstract: A circulatory support system may include a blood pump and a controller. The blood pump may include a driven component and a motor in communication with the driven component and the controller to drive the driven component to pump a blood flow through the blood pump. The controller may be configured to receive a value of a circulatory parameter related to blood flow through a patient, determine a value of a command signal based on the received value, and output the command signal to the motor to drive the driven component at a speed configured to achieve the value of the circulator parameter related to blood flow through the patient.

Abstract: According to one aspect, a tissue fastening device may comprise a body configured to include a plurality of fasteners; an anvil rotatable relative to the body; and a tissue cutting device. The body may define a longitudinal channel configured to receive the tissue cutting device. The tissue fastening device may further comprise a fastener actuator configured to move proximally relative to the body to deploy the plurality of fasteners from the body; and an actuation wire coupled to the tissue cutting device and the fastener actuator. The actuation of the actuation wire may cause the fastener actuator to deploy at least one of the plurality of fasteners into tissue distally of tissue cut by the tissue cutting device.

Abstract: An example medical device is disclosed. The medical device includes a catheter shaft including a distal end portion, wherein the distal end portion includes an ablation assembly. The ablation assembly includes an expandable frame including a base, an end region and a plurality of struts extending between the base and the end region, the struts defining a plurality of apertures along the frame. The ablation assembly also includes an electrical circuit coupled to an inner surface of the second end region of the frame, the electrical circuit including a plurality of ablation electrodes coupled thereto. Further, the expandable frame is designed to shift from a delivery configuration in which the ablation electrodes face inward from the inner surface of the expandable frame to an expanded configuration in which the ablation electrodes face away from the base of the expandable frame.

Abstract: A medical stent includes an elongate tubular body extending from a proximal end region to a distal end region. The distal end region of the elongate tubular body may be adapted to resist migration as a result of peristaltic force. The distal end region of the elongate tubular body may include two or more longitudinally-extending voids and two or more longitudinally-extending dynamic engagement features that are defined between adjacent longitudinally-extending voids. The two or more longitudinally-extending dynamic engagement features are adapted to splay radially outwardly in response to an applied peristaltic force, thereby dissipating the applied peristaltic force.
