Publication number: 20100179484Abstract: A device for introducing a catheter guide wire into a vessel of a patient has a connector and a straightener for a J-shaped end of the guide wire, the connector having an axial bore, and its distal end and proximal end permitting a connection of the Luer type to a needle and to a syringe, respectively. The connector supports, on its inside, a sealing valve equipped with a slit, and the axial bore has, in its portion between the sealing valve and the distal end of the connector, a leaktight mating surface, the shape of which is such that it permits liquid-tight mating with the outer surface of the distal end of the straightener, when the latter is introduced into the connector via the sealing valve.Type: ApplicationFiled: July 2, 2008Publication date: July 15, 2010Applicant: VYGONInventors: Jean-Luc Carrez, Valery Dalle, Pierrick Guyomarc'h

Patent number: 7682331Abstract: A device for introducing a catheter into a body site through the skin by means of an security non-piercing cage includes a steel spring flexible blade which is disposed in the cross section of the chamber of the nonpiercing cage near the proximal input thereof perpendicularly to a needle and is penetrable by the needle. The blade and the needle are adapted to interact in such a way that the blade is in a resting position and freely transversable by the needle when the needle is pushed in a distal direction, and the blade stops the needle and is flexed thereby when the needle is pulled in a proximal direction beyond a determined axial position in such a way that the flexed blade tilts the needle and exposes the inclined needle to a restoring force which pushes the needle off in the distal direction until the puncture end is stopped against the chamber wall. The invention can be used for intravenous catheters.Type: GrantFiled: February 14, 2005Date of Patent: March 23, 2010Assignee: VygonInventors: Jean-Luc Carrez, Valéry Dalle, Pierrick Guyomarc'h, Jean-Max Huet

Publication number: 20100030163Abstract: According to the invention, the spring-effect deformation capacity of the valve (5) essentially relates to the plug (Sa) and to an intermediate valve portion (5c) between the plug (Sa) and a tubular gap (6). The valve (5) and the fixed end piece (3) are conformed so that the valve can be permanently tightened on the fixed end piece without forming a significant dead volume in said gap independently from the deformation of the valve, and so that the valve can be maintained on the fixed end piece (3) without any flexion under the action of the mobile end piece. The slot (9) of the valve includes a moulded proximal slot (9A) followed by a pierced distal slot (9B) for communication between the moulded slot and said gap when the slot is open. Application in medical fluid connectors.Type: ApplicationFiled: January 3, 2008Publication date: February 4, 2010Applicant: VYGONInventors: Jean-Luc Carrez, Valery Dalle, Pierrick Guyomarc'h, Jean-Max Huet

Publication number: 20090277460Abstract: The invention relates to an operating drape formed by an impermeable web that has a window (3) for access to the operating site, characterized in that the web consists of two impermeable sheets (10,20) held together, one along the extension of the other, in a sealed manner by an adhesive that allows the sheets to be separated by peeling and in that the window (3) is shared between the two sheets. The invention applies in particular to operating drapes used in surgery.Type: ApplicationFiled: January 19, 2007Publication date: November 12, 2009Applicant: VYGONInventors: Jean-Luc Carrez, Valery Dalle, Xavier Hocq, Patrick Lestoquoy

Publication number: 20070179446Abstract: The invention relates to positioning a cannula in a vein. A tab (11) is provided on a movable member (9, 10) comprising a wall (10) with a through-hole (12) therein for inserting a needle in such a way that inserting the needle into the through-hole holds the tab in a retaining position on a flange of the base (2) of a catheter (1), wherein said wall (10) is transversely slidably mounted in the chamber of the needle stick guard (6) relative to the needle between a lower retaining position and an upper release position so that when the needle is retracted into the guard and spaced back from said hole, the wall (10) that no longer has the needle extending therethrough can slide into the upper position thereof, thereby raising said tab above the flange of the base and enabling the guard to be separated from the catheter base. The invention is suitable for use in intravenous catheters.Type: ApplicationFiled: March 2, 2005Publication date: August 2, 2007Applicant: VygonInventors: Jean-Luc Carrez, Pierrick Guyomarc'h, Valery Dalle, Jean-Max Huet

Publication number: 20070179447Abstract: The invention relates to placing a cannula by means of a needle and a non-piercing cage. A hook is formed on the end (6a) of a holding member (6) which is pivotally mounted on a non piercing cage (5) around a transversal axis pivoting in the needle sliding direction in order to be engaged with the flange (12) of the cannula base. An opposite end (6b) of said member laterally contacts the needle when said needle penetrates in the cage. The member is embodied in such a way that it is pivotable about said axis when it is not in contact with the needle in such a way the hook is raised and disengaged from the flange of the base while the opposite end of the member is lowered and interposed in front of the end of the needle puncture, thereby preventing the end of exiting from a chamber through the distal exit thereof. Said invention can be used for intravenous catheters.Type: ApplicationFiled: February 2, 2005Publication date: August 2, 2007Applicant: VygonInventors: Jean-Luc Carrez, Valery Dalle, Pierrick Guyomarc'h, Jean-Max Huet

Publication number: 20070076401Abstract: The invention relates to connectors which are intended for use in the medical field. The entry diameter and the thread crest diameter of the inventive connectors are selected in relation to the corresponding diameters of standard connectors such that the assembly of a male connector (A, C) or a female connector (B, D) respectively with a standard female or male connector is prevented because the end piece of the male connector cannot penetrate the inlet duct of the female connector or because said penetration is stopped when the head of the female connector comes into contact with the flange ring of the male connector. The invention is suitable, for example, for enteral nutrition lines.Type: ApplicationFiled: December 3, 2004Publication date: April 5, 2007Applicant: VygonInventors: Jean-Luc Carrez, Valery Dalle, Pierrick Guyomarc's, Michel Tempereau
