摘要:
This invention is a fully implanted functional electrical stimulator (20) apparatus, a method for treatment of obstructive sleep apnea that provides for both reliable detection/prediction or airway occlusion that relieves, and/or prevents same by selective, direct electrical stimulation of the hypoglossal nerve (HG). The method, and apparatus sense hypoglossal nerve electro-neurogram activity for purposes of detecting or predicting obstructive sleep apnea. The sensed hypoglossal nerve activity, itself, is used to trigger functional electrical stimulation of the hypoglossal nerve in order to improve upper airway patency. Further, an improved hypoglossal nerve stimulation electrode (10) interface (IC) is provided that allows for simultaneous hypoglossal nerve activity sensing, and stimulation by eliminating stimulation artifacts that would otherwise trigger further erroneous stimulation.

The invention relates to packaging for folding intraocular implants having a flexible optical portion. The packaging (70) comprises: a base (31); folding support means (30) for supporting the optical portion (24) and comprising a folding edge (34) substantially parallel to said base, which edge is suitable for coming into contact with a portion of the bottom face of the optical portion (24) and forms a longitudinal axis (32) enabling the implant to be folded along said folding axis (28) on either side of said folding edge (34); and positioning means (50; 56; 60) designed to co-operate with at least a portion of the peripheral zone (26) of the optical portion (24) to support the implant and to enable the folding axis (28) of the implant to be maintained in the same vertical plane as the longitudinal axis (32) of said fold support means (30).
摘要:
A method for treating a medical condition, such as obstructive sleep apnea, includes the step of stimulating a nerve, particularly the hypoglossal nerve, using at least one of the following techniques: (a) continuous low-level electrical stimulation; (b) electrical stimulation synchronized with a physical process, such as inspiration, without feedback from the nerve being stimulated; and (c) intermittent electrical stimulation at controlled intervals based on the patient's metabolism.

The invention relates to an intraocular implant made of a flexible material presenting an optical refractive index included between 1.40 and 1.56 including an optic portion (10) and a haptic portion, the optic portion generally being circular. The optic portion of the implant has a cylindrical circumferential surface (16) with a width e of 0.1-0.3 mm and a diameter De of 5-7 mm, and two main surfaces (12, 14), each consisting of a spherical cap (18) of which the geometrical axis coincides with the optical axis and a frusto-conical surface (20) with an inner edge connected to the edge of the spherical cap via a toroidal surface portion (22), and an outer edge connected to said circumferential surface, the thickness E of said optic portion being between 1 and 1.5 mm along the optical axis.

The present invention relates to a means for mutually aligning the scales of a rope streamlined by means of scales articulated to rotate about its axis, the alignment being necessary to enable such a rope to be wound onto the drum of a winch. It mainly consists of a device presenting a bevelled front face and comprising a cavity extending from front to rear, inside which passes the rope before it is wound. The cavity presents a longitudinal opening with two lateral edges, each edge following, from front to back, a profile in helical form, the two helices being coaxial to each other and with the axis of symmetry of the cavity. The wall of the cavity is also configured so as to follow the cross-sectional profile of the scale all along its path in the device. The device is arranged relative to the drum on which the rope is wound so that, given the length of the edges of the opening, regardless of the orientation of a scale on entering the device, the latter, on exiting, assumes the desired orientation, in the alignment of the adjacent scales. The invention applies notably to the systems for handling tractor ropes streamlined by means of scales, used on a ship to pull a submersible body cast off at sea.

A flat interface nerve electrode provides a plurality of electrical contacts embedded in a non-conductive cuff structure, which acts to gently and non-evasively redefine the geometry of a nerve through the application of a force acting on the nerve without causing damage to the nerve. The cuff is open at one side and has a connection to a lead at the other side. During implantation the open sides of the cuff are closed so as to capture the nerve in the cuff in a single motion.
