Abstract: A conical burr coffee grinder can include a hopper that receives coffee beans, a grinding arrangement beneath the hopper, and a removable container beneath the grinding arrangement. The grinding arrangement can include an inner conical burr within an outer conical burr. At least one conical burr can rotate with respect to the other to grind the coffee beans into coffee grounds and dispense the coffee grounds into the container. The coffee beans and coffee grounds can follow a substantially vertical path from the hopper through the grinding arrangement and into the container, which can be multipurpose. A rotor gear can be coupled to the inner conical burr such that the rotor gear and inner conical burr rotate together as a combined unit. Additional components can include a rotational motor, a geartrain, a removable hopper lid, a grind adjustment assembly, a chute, an ionizer, a base, and a safety switch.

Abstract: Devices and methods are provided for delivering an agent into a patient's body using an injection device that includes a drive module and an injector module coupled to the drive module. The drive module includes a canister and puncture mechanism in a first chamber, a plunger in a second chamber communicating with the first chamber, and an actuator that moves the puncture mechanism to cause a puncture pin thereon to penetrate a septum of the canister and cause the gas within the canister to flow through the first chamber around the canister, and into the second chamber. The injector module includes a piston slidably disposed within an agent chamber and coupled to the distal end of the plunger such that, when the plunger moves from a retracted position to an extended position, the piston is advanced within the agent chamber to deliver an agent therein into a patient's body.

Abstract: Canisters are provided that include a cylindrical body and a cap welded to the body to define a cavity filled with carbon dioxide or other fluid. The canisters may be loaded into a medical device, e.g., to provide an energy source for operating the device. Methods for making such canisters are also provided.

Abstract: Injector devices and methods for using them to deliver medicament into a patient's body, e.g., sub-retinally within an eye, are provided. The injector includes an injector cannula having a soft injector tip. A retractable tip protector tube is slidably disposed on the flow cannula between an extended position in which the tip protector tube covers the entire injector tip, and a retracted position in which the tip protector tube is retracted proximally thereby exposing at least part of the injector tip. Accordingly, the tip protector tube protects the injector tip from being damaged while advancing the injector tip to a target injection site.

Abstract: A system for pressure measurement within a surgical system is disclosed. The system comprises a pressure sensitive disc in communication with at least one applied pressure a magnetic field generator for generating at least one first magnetic field, and at least one sensor for measuring at least one second magnetic field, wherein the at least one first magnetic field at least partially creates the at least second magnetic field; and wherein the at least one sensor produces signal indicative of the distance between the at least one sensor and the at least one second magnetic field.

Abstract: A system and method for detecting and/or capturing a cassette is disclosed. The cassette capture mechanism may be used with a surgical console of a surgical system, wherein the system has a cassette receiving area having at least two alignment sensors and a plurality of capture plungers; and at least two capture hooks which may engage with a cassette, wherein at least one of the at least two alignment sensors produces a signal indicative of the presence of a cassette.

Abstract: A system for a surgical system is disclosed, comprising a system for distributing fluid in a surgical cassette, comprising a first pump head operable by a first drive shaft and a second pump head operable by a second drive shaft, wherein the second drive shaft is at least partially enclosed by the first drive shaft.

Abstract: A system for a surgical system is disclosed, comprising a surgical cassette, comprising a cassette for use with a surgical console, further comprising a first set of fluid channels having a first set of ports, a second set of fluid channels having a second set of ports, at least one rotary valve in fluid communication with the first set of fluid channels, at least one rotary valve in fluid communication with the second set of fluid channels, and a plurality of deformable channels, wherein the deformable channels are fluidly connected to ones of the first set of ports and second set of ports.

Abstract: Gas-powered fluid injection systems and methods are disclosed, e.g., for delivering fluids into a patient's body. An injection device comprises a driver housing which forms and/or encloses a gas pressure source, an actuation piston driven by the gas pressure source and a hydraulic fluid pressurized by movement of the actuation piston. The hydraulic fluid flows through an adjustable valve into a plunger lumen which pushes a plunger of a fluid dispensing device, such as a syringe, to dispense an injection fluid, such as a medicament. The injection device has a movable plunger sleeve which receives the plunger of the fluid dispensing device. The plunger sleeve is moved during the activation and de-activation of the injection device such that it relieves residual pressure in the fluid dispensing device thereby preventing the fluid dispensing device from continuing to dispense injection fluid after the injection device has been de-actuated.

In an exemplary embodiment, the device may include a syringe cartridge and a syringe driver that may be coupled to the cartridge. The cartridge may include a housing including a proximal end, a distal end, and defining an interior, the cartridge further including a piston slidably disposed within the interior for delivering fluid within the interior through a port in the distal end. The driver may include a plunger for advancing the piston within the interior of the housing, a source of pressurized fluid, a valve, and an actuator member coupled to the valve for selectively opening a flow path from the source to the plunger to control flow of the pressurized fluid to advance the plunger to deliver fluid from the interior of the housing at a desired rate.
