A linear electromagnetic machine includes a stator, a translator, and a bearing system. The bearing system maintains alignment against lateral displacement of the translator relative to the stator, as the translator reciprocates axially. More particularly, the bearing system maintains a motor air gap between the stator and a magnetic section of the translator. The stator includes a plurality of stator teeth and windings, which form a plurality of phases. The stator teeth and windings are arranged using a hoop stack with spines to form a stator bore and define the motor air gap. The bearing system can include bearing housings that are configured to form a bearing interface with a surface of the translator. The bearing interface can include a contact bearing or a non-contact bearing, such as a gas bearing. Current is controlled in the phases to convert between electrical energy and kinetic energy of the translator.

A system for tissue approximation and fixation is described herein. A device is advanced in a minimally invasive manner within a patient's body to create one or several divisions or plications within a hollow body organ. The system comprises a stapler assembly having a tissue acquisition member and a tissue fixation member. The stapler assembly approximates tissue from within the hollow body organ with the acquisition member and then affixes the approximated tissue with the fixation member. In one method, the system can be used as a secondary procedure to reduce the size of a stoma within the hollow body organ.

Single fold device for tissue fixation

Devices and methods for tissue acquisition and fixation, or gastroplasty, are described. Generally, the devices of the system may be advanced in a minimally invasive manner within a patient's body, e.g., transorally, endoscopically, percutaneously, etc., to create one or several divisions or plications within the hollow body organ. Such divisions or plications can form restrictive barriers within a organ, or can be placed to form a pouch, or gastric lumen, smaller than the remaining stomach volume to essentially act as the active stomach such as the pouch resulting from a surgical Roux-En-Y gastric bypass procedure. Moreover, the system is configured such that once acquisition of the tissue by the gastroplasty device is accomplished, any manipulation of the acquired tissue is unnecessary as the device is able to automatically configure the acquired tissue into a desired configuration.

Devices and methods for placement of partitions within a hollow body organ

A medical device for managing tissue in an organ, such as the stomach, for retracting or positioning tissue and related organs to allow certain regions of the stomach to be acquired for a gastroplasty procedure. The medical device includes an elongated body having a proximal end and a distal end, and a tissue treatment device attached to the distal end of the elongated body. The tissue treatment device includes a first jaw opposite a second jaw, and each jaw is adapted to acquire tissue. A retractor is disposed along the tissue treatment device and adapted to be moveable from a delivery position to a retraction position to move or manage the tissue of the stomach. The medical device also includes a collapsible barrier disposed between the first and second jaws of the tissue treatment device to direct tissue into the first and second jaws separately.

Remote tissue retraction device

A single fold system for tissue approximation and fixation is described herein. The devices are advanced in a minimally invasive manner within a patient's body to create at least one fold within a hollow body organ. The system comprises a tissue acquisition and folding device and a tissue stapling or fixation device, each of which is used together as a system. The acquisition device is used to approximate a single fold of tissue from within the hollow body organ and the stapling device is advanced through a main lumen defined through the acquisition device and is used to affix the tissue. The stapling device is keyed to maintain its rotational orientation relative to the acquisition device and to provide the user positional information of the stapling device. The acquisition device is also configured to provide lateral stability to the stapling device prior to the stapling device being clamped onto tissue.

Single fold system for tissue approximation and fixation

Devices and methods for tissue acquisition and fixation, or gastroplasty, are described. Generally, the devices of the system may be advanced in a minimally invasive manner within a patient's body to create one or more plications within the hollow body organ. A tissue treatment device attached to a distal end of a flexible elongated member and has a cartridge member opposite an anvil member. The cartridge member and the anvil member are movable between a closed position and an open position, and a moveable barrier is disposed between the cartridge and anvil members to help acquire a dual fold of tissue. The tissue treatment device can be repositioned to form multiple plications within the organ.
