摘要:
Methods, systems, and articles of manufacture provide for wireless communications of brain signals from electrode implants to an external receiver for analysis of the brain signals. The analyzed brain signals are used to locate abnormal brain activity in a subject, such as epileptic seizure foci, or to localize task-specific brain activity.

Systems and methods for using a trocar system are disclosed. The system generally comprises a trocar, a magnet, and a magnetizable cannula. The trocar has a first end and a second end. The magnetizable cannula has a central opening sized to receive the trocar. The magnet is positioned adjacent the second end of the trocar and its magnetic field releasably secures the magnetizable cannula in a position adjacent the second end of the trocar.

A flexible endoscope has an elongate, narrow tube with at least three distinct interior bores. A first of the bores is provided to accommodate surgical devices typically provided in endoscopes. The second and third bores of the flexible tube mount a flexible suture holder and a flexible grasper in the interior of the tube. The suture holder and the grasper are movable through their respective bores relative to the endoscope tube. A distal end portion of the suture holder is curved, whereby extending the suture holder from the endoscope tube and extending the grasper from the endoscope tube will cause a distal end of the suture holder to curve to a position where it intersects with the distal end of the grasper. A length of suture is removably mounted to the distal end of the suture holder. With the suture holder and the grasper moved to their extended positions relative to the endoscope tube, the surgical grasper is in position to grasp and remove the length of suture from the distal end of the suture holder. A pre-tied knot on the length of suture enables the apparatus to be used in endoscopic procedures involving legation of body tissue.

A surgical instrument handle having a cam-actuated system is disclosed. The surgical instrument handle includes a rotating member that defines a cam-actuating surface operatively engaged with a locking member, which is fixedly engaged to a reciprocating member for moving the reciprocating member between a retracted and extended positions. The cam-actuating surface of the rotating member is configured to permit the locking member to slide along the cam-actuating surface such that the tangential angle along the point of contact between the locking member and the cam-actuating surface is maintained at a predetermined angle.

An engine drive electric generator apparatus converts the reciprocating movements of a pushrod of an internal combustion engine to electricity. Each generator apparatus has an electric coil surrounding a combustion engine pushrod, and a magnet on the pushrod that reciprocates with the pushrod through the coil. The relative reciprocating movement between the magnet and coil generates an electric current in the coil that is communicated with a battery of the vehicle to charge the battery.

A method of repairing a patient's ventral hernia involves the steps of joining the patient's left and right rectus sheaths on opposite sides of the hernia, thereby closing the hernia, and cutting through the joined sheaths thereby forming one sheath interior containing the left and right rectus muscles. Next, a piece of surgical mesh is positioned in the joined rectus sheath interior and is sutured over the area of the closed hernia to further reinforce the closure. Additionally, sutures joining the left and right rectus sheaths are reinforced with reinforcing material.

An apparatus and its method of operation hydraulically convert the relative movements between a vehicle wheel and a body of the vehicle to electricity, and use the electricity to recharge a battery of the vehicle. A generator is provided on the vehicle and a hydraulic motor is provided on the vehicle to rotate an input shaft of the generator. A double acting piston and cylinder assembly is operatively connected to each wheel of the vehicle, and each double acting piston and cylinder assembly is connected through a hydraulic circuit to the hydraulic motor. Movements of the vehicle wheels during operation of the vehicle cause reciprocating movements of each piston in each double acting piston and cylinder assembly. The reciprocating movements of the pistons pump liquid to the hydraulic motor and draw liquid from the hydraulic motor to cause operation of the hydraulic motor. The operation of the hydraulic motor drives the generator input shaft, which in turn produces electricity that is supplied to the vehicle battery to recharge the vehicle battery.

An apparatus and its method of operation convert relative movements between a vehicle wheel and a body of the vehicle to electricity that is used to recharge a battery of the vehicle. The apparatus includes a generator provided on the vehicle and a linear motion to rotary motion converter that is connected between a wheel of the vehicle and an armature of the generator. Reciprocating movements of the wheel relative to the vehicle body are converted by the motion converter to rotations of the armature in the generator which produces electricity for recharging the battery of the vehicle.
摘要:
A surgical instrument that is employed in closing a surgical incision made deep into body tissue holds a length of suture and a pair of needles secured to the opposite ends of the suture. The instrument is configured for insertion of the instrument into a body tissue incision, for deploying the needles and suture through body tissue on opposite sides of the incision, and for then withdrawing the needles and suture ends from the incision to tie a knot in the suture ends and thereby close the incision.
