A kit according to the invention includes a tool and an implantable chamber. The implantable chamber comprises a hollow main body delimiting an internal volume opening outwards via a main opening. It further comprises a septum mounted on the main body to close the main opening, and at least one conduit extending from the main body. It also comprises a displacement member, movable relative to the main body, that projects from the main body via the conduit and actuates or sets in motion an element situated in the body of the patient. It lastly comprises a drive mechanism for driving the displacement member situated in the internal volume of the main body, in order to move the displacement member with respect to the main body. The tool includes a proximal maneuvering region and a distal region that is capable of piercing the septum to actuating the drive mechanism.

Kit for maneuvering an element present in the body of a patient, comprising an implantable chamber

The invention relates to a kit including a tubular endoprosthesis having an inner surface delimiting a channel with a longitudinal axis. The kit includes a prosthetic valve designed to be implanted in the channel. The valve includes a supporting frame having an outer surface designed to be pressed against the inner surface, and a flexible cover connected to the frame. The inner surface has at least two segments with variable cross-section along the longitudinal axis. The segments form respectively a proximal stop and a distal stop to lock the axial displacement of the outer surface along the inner surface along two opposite directions.

Kit which is intended to be implanted in a blood vessel, and associated tubular endoprosthesis

A device includes an expandable implant and a hollow stent internally defining a central passage. The hollow stent defines a retention opening of the implant near the distal end thereof. The inventive device also includes a wire-type link for releasably fixing the implant to the stent, which has a traction section introduced into the opening and extending inside the central passage. For the wire-type link, the device includes an internal insulation channel arranged in the central passage and axially fixed with respect to the stent. The insulation channel receives only one wire-type link and defines a channel which is devoid of a link at least between the proximal end of the stent and the retention opening and is placed in the central channel.

A device including a body () including fibers without oxidized cellulose. The body () also includes fibers containing oxidized cellulose.

Medical device intended to come into contact with a patient's tissue and related manufacturing method

The invention relates to a system for injecting a liquid into a body, comprising an implantable chamber disposed under the skin and an injection device including: a base bearing an injection needle having a free end that is intended to be inserted into the chamber; an injection conduit connected to the needle; means for extracting the needle; means that can be actuated to generate excess pressure in the injection conduit; synchronization means between the extraction means and the generation means for actuating the generation means during a needle extraction phase. The synchronization means can essentially only actuate the generation means when the free end of the needle is located in the chamber during the needle extraction phase.

An installation which includes an input station, a sterilization station which includes a sterilization chamber, a desorption station which includes a desorption chamber, and an output station. The installation includes a transporting element which is for transporting multiple objects and which is capable of successively moving the objects from the input station into the sterilization station and into the desorption station as far as the discharge station. The transporting element includes a continuous guiding path, a guide device which is guided by the guiding path. The guided device includes a movement mechanism which is capable of moving the objects between a position for movement along the guiding path and a position for insertion of the objects in the sterilization chamber and the desorption chamber.

The radially deformable tubular prosthesis comprises a lattice that is deformable between a retracted state of small diameter and an expanded state of greater diameter. It includes at least two external hooks defining between them a clamp for hooking in external tissue, the two hooks being carried by the lattice and being movable between a spaced-apart position in which the clamp is open, and a closer-together position in which the clamp is closed.

Tubular prosthesis

Prosthetic implant of the type comprising: a tubular support () of axis X, which can be deformed between a compressed state with a small diameter and a dilated state with a larger diameter, the tubular support comprising a lattice comprising rhombus-shaped meshes (), each mesh having a first diagonal () parallel to the axis X and a second diagonal () perpendicular to the axis X; and at least one resilient membrane (A,B) arranged inside the tubular support. The membrane comprises a fixing portion (), the fixing portion being fixed to a fixing section () delimited by a strand (A,B) of the tubular support, the fixing section being oriented substantially parallel to the axis X.

The invention relates to a device () for injecting a liquid into a body, in particular that of a patient, of the type that comprises: a base () bearing an injection needle () that is to be inserted into the body; an injection conduit () connected to the needle (); means () for extracting the needle () from the patient, including a plunger () mounted such that it can slide in relation to the base () between a needle () use position and a needle () extraction position; and means () for generating excess pressure in the injection conduit () as the needle () is extracted, including a flexible section () formed in the injection conduit (), a cam surface () rigidly connected to the plunger (), and a supporting surface rigidly connected to the base (), in order to compress said flexible section () between the cam surface () and the supporting surface radially and perpendicularly to the needle () as the plunger () slides towards the needle () extraction position. The invention is characterized in that it includes means () for retaining the flexible section () substantially perpendicular to the needle ().

Device for injecting a liquid into a body of a patient

This device comprises a tubular endoprosthesis () of axis (X-X') and a stent () of axis (Y-Y&#x2032;) defining a distal retention opening (A) and a proximal retention opening (B). The device comprises a distal wire-like tie (A) and a proximal wire-like tie (B). Each tie (A,B) forms a retaining loop () running around the endoprosthesis (). Each retaining loop () can stretch between a configuration in which the endoprosthesis () is kept in a contracted state against the stent () and a configuration in which the endoprosthesis () is released. When each retaining loop () is in its releasing configuration, the axis (X-X&#x2032;) of the endoprosthesis () is inclined with respect to the axis (Y-Y&#x2032;) of the stent () when no external stresses are applied. The axis (X-X&#x2032;) of the endoprosthesis () intersects the axis (Y-Y&#x2032;) of the stent in the internal line () defined by the endoprosthesis ().

This implant comprises an endoprosthesis having an axis which can be spontaneously deployed in a radial manner between a compressed configuration and a dilated configuration. The implant comprises at least one radial runner which comprises a separation surface which extends radially with respect to an outer surface of the endoprosthesis and a member which can be deployed away from the axis. The runner is arranged so as to delimit a confinement housing which extends between the separation surface and the outer surface and a radial spacer which is defined by the separation surface and the deployable member. When the implant is retained in a state of radial compression, the maximum radial width of the housing is less than the maximum radial width of the spacer which is not equal to zero.

An injection device comprises: a needle support; an injection needle which is fixedly joined to the needle support and which has a free end which is arranged with spacing from the needle support; and a mechanism for extracting the injection needle, comprising a base and a pushing member which can be moved relative to the base between a position in which the needle is used and a position in which the needle is extracted. The base is permanently connected to the needle support and can be moved relative to the needle support between an inactive position of the extraction mechanism and an active position of the extraction mechanism.
