1. A surgical kit for performing surgery for the treatment of reflux disease, the surgical kit comprising the following components: An implantable motion restriction device configured to impede movement of the lower esophageal sphincter relative to the thoracic diaphragm, the device having at least a portion positioned between the angle of His and the thoracic diaphragm; a lubricant including an antimicrobial agent for use in combination with the implantable motion restriction device; and at least one absorbable suture.

The pressure sensor 10 comprises: a bottomed cylindrical sensor module 11 having inside a pressure receiving chamber C1 communicating with a flow path and including a diaphragm 11a in contact with the pressure receiving chamber; a pressure detecting element 12 for outputting a strain of the diaphragm 11a as a pressure; a base ring 14 fixed at an outer edge of an open-side end part 11c of the sensor module and disposed on an outer peripheral side of the sensor module 11; a hermetic member 13 fixed to the base ring 14 for forming a sealed vacuum chamber C2 opposite to the pressure receiving chamber C1 across the diaphragm 11a; a gasket 18 sandwiched between the base ring 14 and a body 5; and a pressing flange 19 for pressing the base ring 14 to the body 5 through the gasket 18.

The present invention relates to a diaphragm that can prevent deformation of the diaphragm and prevent blockage of the flow path by means of a rib formed in the body of a diaphragm having a diaphragm structure of an oil chamber and a gas chamber in a shock absorber constituting a vehicle suspension system. The invention provides a diaphragm without a parting line, and a diaphragm that can increase the rigidity of the product by forming a rib protruding from the inner circumference of the body to secure the flow path even under pressure on the diaphragm or deformation of the product, forming a groove in the rib, forming a reinforcing rib on one side of the rib, and forming an outer circumference rib on the outer circumference of the body.

An apparatus (100) for treating reflux disease in a human patient, the apparatus comprising an implantable movement restriction device (110) shaped and sized for placement against a fundus wall portion (14) of the patient's stomach (10), the movement restriction device being positioned for implantation between the patient's pleural diaphragm (30) and a portion of the gastric fundus wall, and configured to restrict movement of the patient's lower esophageal sphincter (26) of the stomach toward the thoracic diaphragm to prevent the lower esophageal sphincter from slipping through an opening (32) in the thoracic diaphragm and into the patient's thoracic cavity. A first electrode arrangement is configured to contact and electrically stimulate the lower esophageal sphincter (26) to cause contraction thereof, and an inhibitory electrode arrangement (150') is configured to transmit an electrical inhibitory signal to the vagus nerve.

A surgical kit for performing a surgical procedure for treating reflux disease, the surgical kit comprising: an implantable movement restriction device (110, 111a, 111b) configured to be hindering movement of the lower esophageal sphincter relative to the thoracic diaphragm, placed at least partly between the angle of His and the diaphragm, a lubricant including at least a bacteriostatic substance for use with the implantable movement restriction device, and at least one resorbable suture (153).

The invention provides a closed-loop transtracheal phrenic nerve stimulation control system and a method thereof, the closed-loop transtracheal phrenic nerve stimulation control system is characterized by comprising a control unit, a stimulation generator, a tail end electrode and a detection unit, the control unit drives the stimulation generator to generate stimulation current, the stimulation current stimulates a diaphragm through the tail end electrode, and the detection unit detects the diaphragm. The detection unit detects electromyographic signals of the diaphragm through the tail end electrode, the control unit receives and processes the electromyographic signals in real time and dynamically adjusts stimulation current parameters according to a preset algorithm, and therefore closed-loop regulation and control are achieved; the control unit is in communication connection with the respirator to ensure synchronization of electrode stimulation and autonomous respiration. The invention has the advantages that: a closed-loop feedback control strategy is adopted, through the tail end electrode integrating stimulation and detection functions, accurate electrical stimulation of diaphragm and real-time monitoring of electromyographic signals (EMG) are realized, the system integration level is improved, and the implantation burden is reduced.

An implantable medical device for treating reflux disease includes a movement restriction device configured to be anchored to the stomach wall to prevent movement of the lower esophageal sphincter relative to the thoracic diaphragm. The movement restriction device includes a first portion, a second portion, and a first distance element. The first and second portions are configured to be connected to each other to form at least a portion of a functional movement restriction device. The first and second portions are detachable from each other to allow the first and second portions to pass independently through the gastrointestinal tract, and the first distance element is configured to form a space between the first and second portions, the space being configured to allow fibrous tissue ingrowth between the first and second portions.

This invention discloses a structure for improving the anti-interference capability of a high-sensitivity QD acquisition circuit in a spaceborne laser communication terminal optical controller, and provides a design method. The structure includes a chassis cavity, a suppression cavity, and a shielding cover. The chassis cavity and shielding cover minimize the entry of interfering electromagnetic signals, while the suppression cavity attenuates interfering electromagnetic signals entering the chassis cavity. The core of this invention lies in the design of the suppression cavity, which consists of a transverse diaphragm, a longitudinal diaphragm, and an isolated diaphragm, with the transverse and longitudinal diaphragms forming a periodic cavity. This invention significantly improves the anti-interference capability of the QD acquisition circuit in its sensitive frequency band, achieving a suppression capability of over 10 dB.

An implantable medical device for treating reflux disease, the implantable medical device comprising a movement restriction device (110) configured to be fixated to the stomach wall for hindering movement of the lower esophageal sphincter relative to the thoracic diaphragm. The movement restriction device comprises central part (111e), and at least two outer parts (111a-d) configured to be connected to each other along a vertical plane. The at least two outer parts are configured to be connected to the central part for forming at least a portion of a functional movement restriction device. The central part comprises at least one horizontally extending rim (151h1-4) and the central part has a contacting surface configured to contact at least one surface of the at least two outer parts, and wherein a portion of the horizontally extending rim is wedge-shaped with an angle in the range 20° - 60°.
