A system and method for supplying microwave energy to tissue for microwave therapy includes an electrosurgical generator having an output for coupling to a surgical instrument. The electrosurgical generator includes a microwave energy source and a controller for controlling the operation of the electrosurgical generator. The surgical instrument, coupled to the electrosurgical generator, includes a microwave antenna for delivering microwave energy from the microwave energy source. The controller of the electrosurgical generator is operable for causing the electrosurgical generator to apply at least two pulses of microwave energy.

A system for obtaining signals related to electrical activity of the heart of a subject includes a sensing device including an elongate member having a distal end configured for placement within a body lumen of a subject, and a proximal end configured to extend from the subject, an actuation portion carried by the elongate member and configured for placement within the body lumen, the actuation portion having a low-profile state for delivery within the body lumen and an expanded state, and one or more sensors disposed on the actuation portion, each including a contact surface configured to contact an interior wall of the body lumen, wherein the actuation portion is configured to cause the contact surface of each of the one or more sensors to contact a location on the interior wall of the body lumen to provide a signal component for producing one or more electrocardiogram signals.

Devices, systems, and methods useful to engage tissue using suction and to perform medical procedures during sectional engagement. The present disclosure includes disclosure of a tension apparatus, comprising an elongated portion; and a head portion at a distal end of the elongated portion, the head portion comprising one or more arms, whereby a suction lumen extending along the elongated portion and the one or more arms terminates at one or more suction openings at each of the one or more arms.

A surgical stapling instrument is disclosed. The surgical stapling instrument includes an anvil configured to clamp a tissue, a circular stapling head assembly comprising a first row of staples and a second row of staples, a first staple driver configured to drive the first row of staples, a second staple driver configured to drive the second row of staples, wherein the first and second staple drivers are independently actuatable. A motor is coupled to the anvil. The motor is configured to move the anvil between a first position and a second position. A control circuit coupled to the motor. The control circuit is configured to set a stroke length for the first and second staple drivers to a first length, detect a malformed staple in the first row of staples, and set the stroke length for the second staple driver to a second length.

Generally, abnormal pressures in the sinus cavity can have physiological effects due to stimulation or injury of various nerves that are in proximity to the sinus, including increased or decreased pressure on the nerves as well as extrusion of the nerves into the sinus cavities due to bony dehiscence. Methods and devices for alleviating disorders associated with the sinus cavities are described. Embodiments herein include diagnosing these disorders by occluding or restricting the sinus ostium and assessing the physiological effects caused by the occlusion/restriction and treating these disorders by navigating/directing a dilating device to the sinus ostium and dilating the sinus ostium. Other embodiments are directed to devices for maintaining the ostial opening.

A neuromodulation system comprising: at least one input means for inputting patient data into the neuromodulation system; at least one model calculation and building means for building a patient model, the patient model describing the anatomy and/or physiology and/or pathophysiology and the real and/or simulated reaction of the patient on a provided and/or simulated neuromodulation; at least one computation means for using the patient model (M) and calculating the impact of the provided and/or simulated neuromodulation. The present invention further relates to a method for providing neuromodulation.

The present application relates to an assembly for replacing a heart valve or coronary angioplasty assembly, including an insertion sheath (13) of an introducer (1) or a delivery catheter (1′), which is smaller in size than an introducer, intended for being inserted into an artery of a human body. The application involves integrating the metal substrate of an electrode of the cardiac stimulator directly into the sheath for insertion into the artery of a patient.
