A pessary system for providing pelvic floor support for USL and other ligaments. The pessary has an elongated probe with independently inflatable balloons each located substantially the same distance from the insertion end of the probe and which inflate into separate radial sectors. The probe can be inserted into a vaginal cavity and the balloons inflated provide mechanical support to the USLs. Independent inflation of each balloon allows the mechanical USL support provided to be varied on left and right sides to compensate for differences in the degree of degradation and positioning of the USL ligaments on either side.

Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.

A balloon catheter includes a housing; a catheter shaft having a proximal end portion disposed in the housing and forming a liquid feeding path communicating with an inside of a balloon attached to a distal end portion; a supply-discharge line connection portion which has an internal space communicating with the liquid feeding path, and to which a supply-discharge line that supplies and discharges liquid to and from the liquid feeding path through the internal space can be connected; and a stopcock capable of closing the internal space of the supply-discharge line connection portion. A position of the supply-discharge line connection portion with respect to the housing is fixed.

The invention relates to, amongst other things, a catheter device comprising a catheter (24) in which a rotating shaft (25) which is made at least partially from a magnetic material is arranged, and a separating device which contains an annular body (27) surrounding the rotating shaft and having a cavity containing a magnetic body (13′), the magnetic body being arranged downstream from a point at which the shaft (25) exits the catheter (24) which it surrounds with respect to the direction of flow of the fluid through the catheter.

An airbag tube apparatus has a hollow tube with a closed end and an open end. A side hole is disposed near the closed end; when matter leaves the airbag tube apparatus, it enters the hollow tube from the side hole and flows out of the open end. A balloon is attached to the hollow tube, and connected to a vent. The balloon in a large volume can flexibly fix animal tissue. A vent is connected to the balloon, a valve, and a pneumatic module to form an air inflator to inflate, hold and deflate the balloon. The valve opens and closes the liquid flow in the vent, and is controlled by a circuit module; the pneumatic module, providing inflating function, is controlled by the circuit module; the circuit module, has a microprocessor unit, a memory unit and an input-and-output unit.

Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents within the GI tract. Many embodiments provide a swallowable device for delivering the agents. Particular embodiments provide a swallowable device such as a capsule for delivering drugs into the intestinal wall or other GI lumen. Embodiments also provide various drug preparations that are configured to be contained within the capsule, advanced from the capsule into the intestinal wall and degrade to release the drug into the bloodstream to produce a therapeutic effect. The preparation can be operably coupled to delivery means having a first configuration where the preparation is contained in the capsule and a second configuration where the preparation is advanced out of the capsule into the intestinal wall. Embodiments of the invention are particularly useful for the delivery of drugs which are poorly absorbed, tolerated and/or degraded within the GI tract.

A system for inflating a cryogenic ablation catheter balloon, the system comprising a fluid source containing a fluid in a liquid state, a first supply line fluidly coupled to the fluid source and configured to be fluidly coupled to an internal space within the cryogenic ablation catheter balloon, the first supply line including an inline multi-stage pressure regulating system. The multi-stage pressure regulating system includes a first stage configured to cause the fluid to transition from the liquid state to a gas state, and a second stage downstream of the first stage configured to maintain the fluid downstream of the second stage at a pressure corresponding to an inflation pressure of cryogenic ablation catheter balloon.

Devices and methods for balloon delivery of rapamycin and other hydrophobic compounds to the wall of blood vessels. Balloon catheters, such as those used for stent deployment, are modified with the addition of a reservoir of dry micelles. The micelle preparation is reconstituted and the micelles are mobilized when the aqueous solution used to inflate the balloons is injected into the catheter. The micelles are infused into tissue surrounding the balloon when pressurized fluid within the balloon leaks through the wall of the balloon.

The present invention relates to a device and a method for alternately measuring the thoracic and pleural pressure and for gastropharyngeal or tracheal sealing, wherein the balloon component of a tube or catheter placed in the trachea or oesophagus alternates between two filling or functional states, wherein the filling state of the balloon component in the measuring mode assumes a value of constant, defined volume during the measurement, said value corresponding to a flaccid filling state, and the filling state of the balloon in the oesophageally or tracheally sealing functional mode maintains a constant, sealing pressure specified by the user. The controller device connected to the tube unit or catheter unit ensures rapid displacement of filling medium into and out of the tube balloon or catheter balloon in the state of tracheal or oesophageal sealing, wherein the tracheally or oesophageally sealing target pressure is maintained continuously by compensating pressure fluctuations in the balloon caused by respiratory mechanics by a continuous, compensating displacement of filling volume. The user can switch between the two functional states by means of a manual switchover function or by means of a programmable, chronological cycle. In addition to the possibility of an intermittent monitoring of the respiratory mechanics and a continuous, tracheally or oesophageally sealing balloon tamponade, the balloon placed in the trachea or oesophagus allows, in both functional states, the thoracic derivation of a triggering, respiratory-mechanical signal which can trigger a ventilating stroke assisting the patient in a ventilator connected to the device. The invention also describes structural and functional options for the simultaneous derivation of a neural and/or muscular electrical signal from the diaphragm of the patient and a respiratory-mechanical signal on the basis of thoracic or pleural pressure fluctuations derived tracheally or oesophageally.

A uterine manipulator device includes: an elongated cannulated tube comprising a proximal end and a distal end; a cervical cup having a top proximal portion of a first diameter and a base distal portion of a second smaller diameter, wherein: the base distal portion includes a hole formed therein having a perimeter including a distal end and a proximal end, and including a longitudinal axis positioned therethrough; one of the proximal end of the perimeter and the distal end of the perimeter is angled away from the longitudinal axis and the other of the proximal end of the perimeter and the distal end of the perimeter is in line with the longitudinal axis; and the elongated cannulated tube is positioned through the hole in the cervical cup.
