Medicament delivery device
The present disclosure relates to a medicament delivery device. The medicament delivery device includes a needle for delivering a medicament and an insertion mechanism configured to urge the needle in a first direction parallel to a longitudinal axis of the needle. The insertion mechanism includes a driving mechanism and a cam. The driving mechanism is configured to exert a force in a second direction perpendicular to the first direction. The cam is coupled to the needle and is configured to receive a force from the driving mechanism and move in the first direction in response to the received force.
Insulin leakage sensor with electric control to stop insulin flow
An insulin delivery device (10) includes a cannula (40) for delivering insulin to a patient at an infusion site, a pump assembly (30), and a valve (36) for controlling the flow of insulin. A removable leak detector unit (28) is coupled to the delivery device for sensing and detecting leakage of insulin at the infusion site. The leak detector unit (28) has electrodes (56) positioned for contacting the insulin leaking from the infusion site, a sensing electrical circuit (54) and a power source (58) for operating the leak detector unit. The removable leak detector unit (28) has an electrical contact (62) for mating with an electrical contact (64) of the delivery device for electrically and operatively connecting the leak detector unit (28) to the delivery device. The leak detector unit (28) sends a signal to the pump assembly (30) and/or valve (36) to stop the flow of insulin when leakage is detected at the infusion site.
Components with high API loading
Components with relatively high loading of active pharmaceutical ingredients are generally provided. In some embodiments, the component (e.g., a tissue interfacing component) comprises a solid therapeutic agent and a supporting material such that the solid therapeutic agent is present in the component in an amount of greater than or equal to 10 wt % versus the total weight of the tissue interfacing component. Such tissue-interfacing components may be useful for delivery of API doses e.g., to a subject. Advantageously, in some embodiments, the reduction of volume required to deliver the required API dose as compared to a liquid formulation permits the creation of solid needle delivery systems for a wide variety of drugs in a variety of places/tissues (e.g., tongue, GI mucosal tissue, skin) and/or reduces and/or eliminates the application of an external force in order to inject a drug solution through the small opening in the needle. In some cases, a physiologically relevant dose may be present in a single tissue interfacing component.
Medicament delivery device comprising a visual indicator
Disclosed herein is a pharmaceutical delivery device comprising a cartridge containing a fluid, the cartridge including a light pipe section which acts as a light pipe having an input location; and a light diffusing section optically coupled to the light pipe; and a light source optically coupled to the cartridge at the input location to the light pipe, such that at least some light from the light source entering at the input location is diffused at the light diffusing section.
Adhesive and peripheral systems and methods for medical devices
A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.
Self-actuating articles
Self-actuating articles including, for example, self-actuating needles and/or self-actuating biopsy punches, are generally provided. Advantageously, the self-actuating articles described herein may be useful as a general platform for delivery of a wide variety of pharmaceutical drugs that are typically delivered via injection directly into tissue due to degradation in the GI tract. The self-actuating articles described herein may also be used to deliver sensors and/or take biopsies without the need for an endoscopy. In some embodiments, the article comprises a spring (e.g., a coil spring, a beam, a material having particular mechanical recovery characteristics). Those of ordinary skill in the art would understand that the term spring is not intended to be limited to coil springs, but generally encompass any reversibly compressive material and/or component which, after releasing an applied compressive force on the material/component, the material/component substantially returns to an uncompressed length of the material/component (e.g., the within 95% of the length of the material/component prior to compression).
Bent fluid path add on to a prefilled reservoir
An add-on for a self-injector including an adaptor and a bent fluid path is provided. The adaptor includes at least one coupling sized and shaped to couple the adaptor to a fluid reservoir. The bent fluid path is configured at a first end to penetrate tissue and coupled at a second end to the adaptor. The add-on coupled to the fluid reservoir forms an integral self-injector cartridge unit configured to be sterilized and filled with an injectable. The adaptor is configured to couple to a self-injector at least one of a plurality of reservoirs having different sizes and tip types.
BENT FLUID PATH ADD ON TO A PREFILLED RESERVOIR
An add-on for a self-injector including an adaptor and a bent fluid path is provided. The adaptor includes at least one coupling sized and shaped to couple the adaptor to a fluid reservoir. The bent fluid path is configured at a first end to penetrate tissue and coupled at a second end to the adaptor. The add-on coupled to the fluid reservoir forms an integral self-injector cartridge unit configured to be sterilized and filled with an injectable. The adaptor is configured to couple to a self-injector at least one of a plurality of reservoirs having different sizes and tip types.
Systems, devices and methods for sustained delivery of a therapeutic fluid
Embodiments of the present invention are directed to devices, systems and methods for delivering therapeutic fluid (e.g., insulin) into the body, including a skin adherable cradle, for retaining a therapeutic fluid dispenser for delivering a therapeutic fluid to a user.
Self-righting articles
Self-righting articles, such as self-righting capsules for administration to a subject, are generally provided. In some embodiments, the self-righting article may be configured such that the article may orient itself relative to a surface (e.g., a surface of a tissue of a subject). The self-righting articles described herein may comprise one or more tissue engaging surfaces configured to engage (e.g., interface with, inject into, anchor) with a surface (e.g., a surface of a tissue of a subject). In some embodiments, the self-righting article may have a particular shape and/or distribution of density (or mass) which, for example, enables the self-righting behavior of the article. In some embodiments, the self-righting article may comprise a tissue interfacing component and/or a pharmaceutical agent (e.g., for delivery of the active pharmaceutical agent to a location internal of the subject). In some cases, upon contact of the tissue with the tissue engaging surface of the article, the self-righting article may be configured to release one or more tissue interfacing components. In some cases, the tissue interfacing component is associated with a self-actuating component. For example, the self-righting article may comprise a self-actuating component configured, upon exposure to a fluid, to release the tissue interfacing component from the self-righting article. In some cases, the tissue interfacing component may comprise and/or be associated with the pharmaceutical agent (e.g., for delivery to a location internal to a subject).
