High efficiency blood pump
A blood pump can include a pump housing, an impeller, and a hub. The pump housing can be configured to move blood from an inlet to an outlet thereof. The impeller can be housed in the pump housing, have a plurality of blades joined by a central ring, and be radially supported at the central ring by a bearing. The hub can transmit torque to the impeller using a radial magnetic coupling.
AUTOINJECTOR, METHOD OF ACTIVATING AN AUTOINJECTOR AND METHOD OF ASSEMBLING AN AUTOINJECTOR
An autoinjector includes a pre-filled syringe arranged within a housing of the autoinjector, a needle shield covering a needle of the pre-filled syringe in a storage state of the autoinjector, an axially moveable needle guard arranged to cover the needle of the pre-filled syringe at least after use of the autoinjector and to move relative to the pre-filled syringe during use of the autoinjector, and a removable cap in which the needle guard is stored in the storage state of the autoinjector, Upon removal of the cap, the needle shield is also removed from the autoinjector.
Airway management device and method of manufacture
An airway management device comprising a body having a proximal end for receiving an oxygen supply tube and an distal end for insertion into a trachea of a patient; said body including a linear portion adjacent to the proximal end and a curved portion adjacent to the distal end; said body including an external shell and having a first bore through said shell for receiving the oxygen supply tube; wherein flexural strength for said airway management device is provided by said shell.
AUTOINJECTOR
An autoinjector basically includes a housing, a pre-filled syringe, a drive chassis, and a needle guard. The pre-filled syringe is mounted in the housing. The drive chassis is configured to move a plunger in the pre-filled syringe to dispense medicament via an urging force from a drive spring. The needle guard is moveable in the housing between a storage state, a dispensing state, and a lock-out state. The needle guard is biased towards an extended position by a lock-out spring. The needle guard selectively engages the housing to establish a frontmost position of the needle guard in the storage state, and an offset position of the needle guard in the lock-out state. The offset position is axially offset from the frontmost position in the distal direction.
Fluid delivery systems and methods
A method of dispensing fluid includes three processes. A first one of these processes includes pumping fluid into a resilient variable-volume dispensing chamber. The dispensing chamber is in series with a normally present finite fluid impedance and an output. The impedance is sufficient so as to cause expansion of the dispensing chamber as it receives pumped fluid even while some fluid flows through the output. Another one of these processes includes repeatedly measuring a parameter related to volume of the dispensing chamber over time. A third one of these processes includes controlling the pumping of fluid based on repeated measurements of the parameter to produce a desired fluid flow through the output. A corresponding system for dispensing fluid implements these processes.
Elastic introducer sheath
An elastic percutaneous elastic introducer sheath is disclosed which can locally expand and reduce to accommodate a transcatheter medical device. The elastic introducer sheath includes a non-circumferentially continuous elastic frame, a liner, and a jacket.
Versatile syringe platform
Apparatus and methods for medicament delivery. The apparatus may include, and the methods may involve, a delivery device for delivering a target amount of the medicament from a distal end of the device. The device may include a rod for moving a plunger that discharges the medicament from the distal end. The device may avoid or reduce deformation of the plunger during the discharge. The plunger motion may be stopped by detent that interacts with the rod. The apparatus and the methods may provide an operator indication of progress of stages of operation. The device may feature triggers corresponding to stages of medicament displacement from the device, such as pre-delivery stages, including priming.
Protection device for a needle
The invention relates to a protection device (1) for a needle (203) of a tip (201) of a drug delivery device (202), comprising: —fixing means (2) for fixing the protection device to said tip, —protective legs (4) capable of transitioning from a first configuration ration in which they cover the needle, to a second configuration in which the needle is exposed, and to a third configuration in which they cover the needle, via pivot links, —removable maintaining means for maintaining the protective legs in their first configuration, —retaining means (9, 10) for retaining the protective legs in their third configuration, said pivot links comprising elastic return means (5) for automatically transitioning the protective legs from their first configuration to their second configuration. The invention also relates to an assembly comprising a drug delivery device and said protection device, and to a method for manufacturing said protection device.
Injection nozzle and method of making same
A material for an injection nozzle is molded into a form that includes a sacrificial tip around the nozzle exit orifice. The sacrificial tip is then machined away using any suitable machining process to expose the exit orifice. In this manner, an injection nozzle can be fabricated with favorable geometric characteristics.
