Some systems and methods for treating heart tissue may include instruments for intermittently occluding the coronary sinus using a coronary sinus occlusion catheter device. In some embodiments, the coronary sinus occlusion catheter can be used before or during a coronary intervention procedure in which a blockage in a heart is repaired or removed.

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.

A syringe assembly or inflation device that includes a detachable housing. A pressure-sensing syringe assembly or inflation device can include both a syringe barrel and a housing that is coupled to the syringe barrel in a locked configuration. The inflation device can transition from the locked configuration to the unlocked configuration in which the housing is separable from the syringe barrel. Related methods are also disclosed.

An apparatus for medical diagnosis and/or treatment is provides. The apparatus includes a flexible substrate forming an inflatable body and a plurality of force sensing elements disposed on the flexible substrate. The plurality of force sensing elements are disposed about the inflatable body such that the force sensing elements are disposed at areas of minimal curvature of the inflatable body in a deflated state.

A fluid displacement and pressurization device which provides both a substantial amount of thread engagement as well as provides for single hand control for all operational manipulations including maintaining a set fill volume, rapid filling and displacement, and pressurization and retention of evacuation positioning during balloon depressurization. The device allows for the use of one hand to not only transition the device from micro-movement control to macro-movement control, but also regarding rotating, pushing or pulling the handle of the plunger.

According to an aspect, an implantable device includes a pressurize fluid reservoir configured to hold fluid, an inflatable member; and an electronic pump assembly. The electronic pump assembly includes a pump, an active valve, a pressure sensor configured to monitor a pressure of the inflatable member, and a controller configured to cause the active valve to be in an open position during at least a portion of an inflation cycle to allow the fluid to be transferred from the pressurized fluid reservoir to the inflatable member. The controller is configured to transition the active valve to a closed position in response to the pressure of the inflatable member achieving a target pressure.

A bowel irrigation system comprising a container adapted for containing a liquid, a catheter comprising an inflated balloon, a tubing connecting the container and the catheter, a pump, a control unit for controlling a flow of fluid in the system, and a pressure sensor is disclosed. The system comprises means for deflating the balloon, as a response to an assessment of a first pressure inside the balloon being greater than a first threshold value, by reducing the amount of liquid inside the balloon by a first amount of liquid. In addition, a method for deflating an inflatable balloon, as a response to an assessment of a first pressure inside the balloon being greater than a first threshold value, by reducing the amount of liquid inside the balloon by a first amount of liquid is disclosed.

The invention relates to a device for transanally introducing an infusion into the rectum or colon of a patient, said device comprising a catheter with a catheter shaft wherein, to ensure the most practicable catheter insertion possible, the catheter shaft is equipped in the proximal, preanal region with gripping depressions to accommodate the fingers gripping the catheter during insertion.

A gastrostomy device (100) comprises a gastrostomy tube (200) having a retainer lumen (235) extending between a proximal part and a distal part of the tube (200); and an inflatable retaining element (300) coupled to the tube (200) at the distal part. An interior space of the retaining element (300) is in fluid communication with the retainer lumen (300). The gastrostomy device (100) also comprises an indicator (410) being in fluid communication with the retainer lumen (235) at the proximal part of the tube (200). The indicator (410) is configured for indicating a pressure in the retaining element (300) continuously within a range from a pressure corresponding to an empty retaining element (300) to an optimal pressure for the inflated retaining element (300).

The invention relates to devices (1) for draining or closing a natural or artificial bladder outlet by means of a balloon body (3) made of preferably micro-scale thin-walled Polyurethane, which has a vesical anchor, is transurethrally sealing and is extended into the urethra or through the urethra. According to the invention, the balloon body is seated on a shaft body (2) supporting the balloon, and the filling of the balloon body is preferably done with air.
