Disposable fluid injection module
An automated injection module is comprised of a housing, a piston drug capsule disposed within the housing, a piston core including a puncture seal membrane defining a reservoir for holding a drug between the puncture seal membrane and the piston drug capsule, an injection device having at least one sharp end for puncturing the puncture seal upon activation of the device, an end cap on a distal end of the housing, and a pressure source on a proximal end of the housing. The pressure source is preferably a propellant that ignites and forces the piston toward the distal end. Substantially simultaneously, the injection device pierces the puncture seal membrane, the piston core is forced into the piston drug capsule, and the drug is evacuated from the reservoir through the injection device and into a patient.

Fluid injection
ActiveUS20120132288A1Avoid enteringValve arrangementsFlow mixersBiomedical engineeringFluid injection
The present invention generally relates to systems and methods for the control of fluids and, in some cases, to systems and methods for flowing a fluid into and / or out of other fluids. As examples, fluid may be injected into a droplet contained within a fluidic channel, or a fluid may be injected into a fluidic channel to create a droplet. In some embodiments, electrodes may be used to apply an electric field to one or more fluidic channels, e.g., proximate an intersection of at least two fluidic channels. For instance, a first fluid may be urged into and / or out of a second fluid, facilitated by the electric field. The electric field, in some cases, may disrupt an interface between a first fluid and at least one other fluid. Properties such as the volume, flow rate, etc. of a first fluid being urged into and / or out of a second fluid can be controlled by controlling various properties of the fluid and / or a fluidic droplet, for example curvature of the fluidic droplet, and / or controlling the applied electric field.

Methods and apparatus for delivering precise amounts of fluid under pressure into cardiac tissue for the purpose of facilitating ablation of the tissue along a desired lesion line. One method injects fluid under pressure through a discharge orifice in a needle-less injection device. The injected fluid can be a cytotoxic fluid and / or a highly conductive fluid injected in conjunction with radio frequency ablation to create an ablative virtual electrode. The injected fluid can provide deeper and narrower conduction paths and resulting lesions. Radio frequency ablation can be performed at the same time as the fluid injection, using the injection device as an electrode, or subsequent to the fluid injection, using a separate device. In some methods, the injected fluid is a protective fluid, injected to protect tissue adjacent to the desired lesion line. Fluid delivery can be endocardial, epicardial, and epicardial on a beating heart. The present methods find one use in performing maze procedures to treat atrial fibrillation.
