A device for respiratory assistance includes a tube that may include a deflection section and at least one distribution orifice located downstream of the deflection section. The at least one distribution orifice opens into a main channel of the tube opposite an oblong pressure zone and is for being supplied with a medical fluid.

Device for respiratory assistance

A tubular respiratory assistance device which forms the wall of a main channel and is intended to be connected by its distal end to a patient's airway, so that the main channel connects the patient's respiratory system to the outside, and which has at least one auxiliary channel which is associated with deflection means for injecting a respiratory gas jet which is deflected toward the interior of the main channel and is intended to ventilate the patient. The tubular respiratory assistance device also has an annular chamber arranged at the periphery of it, coaxially with it on its distal end, and a distal annular orifice, the annular chamber communicating with the patient's respiratory system by means of the distal annular orifice and being provided with means for connection to the outside. Also, a respiratory assistance mask intended to be fitted to a patient's face which has this tubular respiratory assistance device for inlet and outlet of respiratory gas.

Respiratory aid

A respiratory assistance device comprises a respiratory aid tube whose distal extremity, intended to be introduced into the windpipe of a patient, is provided with an inflatable ballonet and means for bringing the respiratory gas into the lungs of the patient by means of said tube. The device includes pressure sensors in the ballonet and at the distal end of the tube which provide signals to an electronic controller for controlling the feed of respiratory gas to the patient.

Respiratory assistance device

A respitory assistance apparatus which includes:

Respiratory assistance apparatus

Device for respiratory assistance, comprising a tube (4) which forms a main channel (5) and which is intended to be connected via its distal end (3) to the respiratory tract of a patient so that said main channel (5) connects the respiratory system of said patient to the outside, with said device moreover comprising at least one auxiliary channel (8) formed in the wall of said tube (4) and permitting the insufflation of a respirable gaseous jet into said respiratory system and opening into said main channel (5) in the vicinity of the distal end (7) of the latter. According to the invention, this device is distinguished by the fact that it comprises a controlled valve (21) capable of closing at least partially the proximal end of said main channel (5), at least during insufflation of said gaseous jet.

The present invention relates to a dilatation catheter designed to be introduced into a canal of the body. The invention finds a particular application in the treatment of diseases of the coronary arteries. According to the invention, the balloon has an outer wall designed to come into contact with the inner wall of the body canal, while in the position of use, and an inner wall fixed in a tight manner to the outer wall to define therewith, while in the position of use, an inner annular cavity. The catheter further includes a support element shaped so as to hold the inner wall of the balloon, in the position of use, while allowing the body fluid to flow in the space between an inner element and the inner wall of the balloon.

Dilatation catheter for perfusion

A catheter for a morphological duct is disclosed, comprising an inflatable sleeve surrounding the distal end of said catheter and connected to the proximal end of said catheter by at least one inflating conduit which can be connected to an inflating device and said inflatable sleeve may take on either a deflated state in which it is applied against said distal end of said catheter, or an inflated state in which it is applied by its external wall against the internal wall of said morphological duct, then forming an annular space between its internal wall and said distal end of said catheter.

Endoprosthesis catheter

Breathing aid

Probe intended to be introduced within a living body

This invention relates to a catheter for shooting a laser beam, comprising an optical fiber contained in a sheath, as well as an optical system, wherein said optical system obturates the distal end of said sheath, and, between the distal end of said optical fiber and said optical system, there is formed a chamber which is in communication with a supply conduit and with a return conduit for an optically neutral cooling fluid.
