The invention relates to a fluid pump comprising at least one impeller blade (1, 1′, 1″) which is rotatable about an axis of rotation (3) and conveys a fluid in operation and comprising a support device (4, 6, 7, 8, 9, 10, 12, 12′, 13, 13′, 14, 14′, 15, 17) which supports the at least one impeller blade (1, 1′, 1″) in at least one support region, wherein the support device is changeable between a first state in which the rotor is radially compressed and a second state in which the rotor is radially expanded; and wherein at least one impeller blade extends at least partly radially inwardly with respect to the axis of rotation (3) from the support region/support regions in the radially expanded state of the rotor.

A wearable infusion pump assembly. The wearable infusion pump assembly includes a reservoir for receiving an infusible fluid and a fluid delivery system configured to deliver the infusible fluid from the reservoir to an external infusion set. The fluid delivery system includes a controller, a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the external infusion set, the pump assembly comprising a pump plunger, the pump plunger having distance of travel, the distance of travel having a starting position and an ending position, at least one optical sensor assembly for sensing the starting position and ending position of the pump plunger distance of travel and sending sensor output to the controller, and a first valve assembly configured to selectively isolate the pump assembly from the reservoir, wherein the controller receives the sensor output and determines the total displacement of the pump plunger.

A disposable, single-dose delivery device for self-administration by a patient of a predefined amount or dose of drug from a reservoir through an outlet of the reservoir includes a device operation lock to prevent a delivery operation of the delivery device as shipped to the patient, an embedded electronic control unit with a wireless receiver for receiving an unlock command or message, and an electromechanical actuator for mechanically unlocking the device operation lock and enabling delivery device operation by the patient. The control unit is configured to activate the actuator instantaneously and unconditionally upon receipt of the unlock command. The unlocking mechanism of the delivery device is adapted to be activated from remote in response to a confirmative message indicative of additional double check by a Health Care Professional HCP or expert system.

A steerable device including a flexible axially elongated member, at least one actuating element arranged alongside the periphery of the elongated member, at least one fastening element configured to fasten at least partially the at least one actuating element to the flexible elongated member distal end, the fastening element being in direct contact with the flexible elongated member, at least one anti-return element configured to keep the at least one actuating element from sliding alongside the periphery of the flexible elongated member distal end, wherein the at least one anti-return element and the at least one fastening element are in axial abutting contact.

A drug delivery device includes a housing, a container at least partially disposed within the housing and configured to contain a medicament, an injection mechanism at least partially disposed within the housing and configured to exert a force to urge the medicament from the container, a drug delivery component at least partially disposed within the housing, and at least one pin positioned adjacent to the housing and preventing activation of the activation mechanism until the at least one pin reaches a desired temperature.

The embodiments described herein relate to a self-positioning, quick-deployment low profile transvenous electrode system for sequentially pacing both the atrium and ventricle of the heart in the “dual chamber” mode, and methods for deploying the same.

Shape memory alloys are used in aerospace structures, orthodontics, cardiovascular prosthetic devices, sensors and controllers, and many other engineering, technology, science, and other fields. The methods are described in the case of a temporary heart assist pump to illustrate the concepts, but the method applies to many other fields. The properties of shape memory alloys are used to fold or collapse and implant in the human body a device without breaking the device as it reaches body temperature or without reaching permanent plastic deformation. The properties of nitinol are also used to describe intended explantation of the device, at body temperature, from the body without breaking it. Such planned explantation may be needed in cases where the device is designed for temporary use, such as mechanical circulatory support devices intended for temporary use and then removal of all components of the device from the body. The same method can be used for devices that have not been initially designed for removal, such as stents or valves, that must later be explanted for reasons unanticipated when they were installed. The methods ensure that the devices stay within stress-strain-temperature conditions so they remain elastic, or under the upper stress plateau, or remain plastic, but always under the breaking strain, of shape memory alloys at: room or environmental conditions; cooler than environmental conditions; and at a higher temperature, or body temperature. The methods described may also be applied to other industrial applications, where shape memory alloys may be installed and removed at different temperatures. Applications in other industries, include aerospace, civil structures, mechanical structures are contemplated.
