Inflation devices configured to communicate with remote displays are disclosed herein. Kits including such inflation devices with portable display devices are also disclosed herein. Methods of remotely displaying pressure data from a medical device are also disclosed herein. Devices, kits, and methods of connecting medical devices to remote displays and transferring information to or from linked computers are also disclosed.

A cuff pressure stabilizer includes a substantially rigid protective housing and a balloon disposed therein. The balloon has a base low pressure of 10 cm H2O when it contains a base low-pressure volume of air. When the balloon contains a first medium-pressure volume of air, the balloon has a first medium pressure of 25 cm H2O. When the balloon contains a second medium-pressure volume of air, the balloon has a second medium pressure of 40 cm H2O, and at least 20% of an outer surface of the balloon touches a portion of the inner surface of the housing. The second medium-pressure volume of air equals the base low-pressure volume of air plus a second incremental quantity of air that is less than 60 cc. Other embodiments are also described.

A housing for use in connection with an inflation device can be coupled to a syringe body by a snap-fit connection. The snap-fit type mechanism can include an adaptor and a lock, such as a depressible lock. The housing can enclose an electrical circuit and a display screen that rests on a plurality of resilient pins. The circuit board may be held in place within the housing via one or more heat pins. The inflation device can be configured to measure pressure within a fluid reservoir of a syringe.

A system for treating an aneurysm comprises an elongate flexible shaft and an expandable member. An expandable scaffold is disposed over the expandable member and may be expanded from a collapsed configuration to an expanded configuration. A double-walled filling structure is disposed over the scaffold and has an outer wall and an inner wall. The filling structure is adapted to be filled with a hardenable fluid filing medium so that the outer wall conforms to an inside surface of the aneurysm and the inner wall forms a substantially tubular lumen to provide a path for blood flow. In the expanded configuration the scaffold engages the inner wall of the filling structure. A tether is releasably coupled with the filling structure and the flexible shaft thereby constraining axial movement of the structures relative to each other.

An endoscope device includes: a balloon; a balloon controller; a remote controller capable of inputting a plurality of types of balloon operations including an inflation operation and a deflation operation of the balloon; a controller operation switch (multifunctional switch) for operating the balloon controller, the controller operation switch being provided in an endoscope and capable of inputting a plurality of types of the balloon operations that are common to the remote controller; and a processor (display control unit), in which the processor is configured to, in a case in which the balloon operation is input to the controller operation switch, reflect a type of the balloon operation input to the controller operation switch on a remote controller image displayed on a monitor.

Devices used to pressurize, depressurize, or otherwise displace fluid are disclosed. The devices may be configured to displace fluid in order to inflate or deflate a medical device, such as a balloon. The devices include a trigger configured to convert the devices from a pressurization state to a priming state. The devices further include a locking or toggle member configured to toggle and/or maintain the devices in a priming state.

A balloon resection method is disclosed generally including inserting a catheter with at least one balloon having an outer wall with a resecting, non-slip surface for resecting unwanted biological material, such as tissues or tumors, and supplying fluid thereto in pulsed fashion to repeatedly deflate and inflate the balloon. In certain embodiments, a pump controls the pulsed supply of fluid based on an established frequency or change in volume. In some embodiments, the a keyed connector is used to identify the balloon type, and in some cases, intra-lumen diameters and densities are calculated. In some embodiments, the balloon portion of the catheter includes multiple balloon segments, which in some cases, are inflatable separately from one another.

An apparatus includes a body, a shaft assembly, a deflection actuation assembly, and a dilation catheter. The shaft assembly includes a rigid proximal portion and a flexible distal portion. The deflection actuation assembly includes a rotary actuator and a first translatable actuation member at least partially disposed within the first rotary actuator. A second translatable actuation member extends through the shaft assembly and couples the first translatable actuation member with the flexible distal portion of the shaft assembly. The first rotary actuator is rotatable about a longitudinal axis to thereby drive the first and second translatable actuation members longitudinally. The flexible distal portion is configured to deflect away from the longitudinal axis in response to translation of the first and second translatable actuation members longitudinally. The dilation catheter is slidable relative to the shaft assembly and includes an expandable dilator.

An apparatus includes an instrument body, a shaft assembly, a dilation catheter, a guidewire, and a proximal deflection actuation assembly. The dilation catheter includes an expandable dilator and is slidable relative to the shaft assembly to thereby position the dilator distally relative to the distal end of the shaft assembly. The proximal deflection actuation assembly is positioned at the proximal end of the shaft assembly and is operable to selectively deflect the length of the shaft assembly relative to the longitudinal axis of the instrument body to thereby deflect the longitudinal axis of the shaft assembly away from the longitudinal axis of the instrument body.

A volume indicator for a syringe can include an indicator body configured to removably clip onto a syringe body and a window portion extending through a thickness of the indicator body. The volume indicator can include inflation indicia corresponding to a range of expanded diameters for a prosthetic heart valve. The volume indicator can include one or more first engagement elements that correspond to one or more second engagement elements on a syringe.
