Abstract:

A catheter for introduction and removal of fluids from a body and tunneling device therefor, the catheter has a body having a first conduit for removing fluid from the body and a second conduit for delivering fluid to the body wherein at least a part of each of the conduits is integrally formed within a first end of the body of the catheter and extends along side one another. The first conduit extends beyond the second conduit and forms a terminal point of the first end and defines a first opening thereat and the second conduit extends to a point short of the terminal point defining a second opening. A bumper portion is adjacent the second opening extending toward the terminal point. Another part of each the first and the second conduits are disjoined and form part of a second Y-shaped end. The tunneling device has a channel to removably receive the catheter.

International Classification:

A61M 39/06

US Classification:

60416704

Abstract:

A catheter introducer valve comprising a body having an upper surface and a lower surface; a rim having a portion thereof extending beyond the upper surface and a portion thereof extending beyond the lower surface; a substantially conical depression formed in the body extending from an outer portion proximate to the upper surface and tapering toward an inner portion; an aperture formed in the body coaxial with the conical depression, the aperture having a conical first portion, a second portion comprising a first slit coaxial with the first portion and extending from the conical depression inner portion into the body, a third portion comprising a slit flaring outward from and at least partially intersecting the aperture first portion toward the bottom surface; a first thickened portion associated with the bottom surface; and, a second thickened portion associate with the bottom surface and generally perpendicular to the first thickened portion.

Anandkumar Bhate - North Bergen NJ
David Catlin - Middletown NJ

Assignee:

Meadox Medicals, Inc. - Oakland NJ

International Classification:

A61M 2902

US Classification:

606194

Abstract:

A dilatation catheter having an outer tubular balloon portion with length-wise circumferential crimps having at either end transition portions with longitudinal crimps across the axis and an inner catheter is provided. The distal transition portion is fastened to the distal end of the inner catheter tube which extends beyond the distal end of the outer tube and the balloon portion while the proximal transition portion is connected to the distal end of the outer catheter tube. The balloon portion expands readily to a predetermined diameter while undergoing little change in length with an extension of the transition portions so that relative movement of the inner and outer catheter tubing is not required. Accordingly, minimum shear forces occur at the interface of the expanded balloon surface and the interior vessel wall.

Inventors:

David G. Catlin - West Chester PA

Assignee:

Thomas Medical Products, Inc. - Malvern PA

International Classification:

A61M 500

US Classification:

604167

Abstract:

A Y-connector including a hemostatic valve for enabling the introduction of an elongated member, e. g. , a balloon catheter, into the body of a living being while precluding blood from flowing out of the valve. The Y-connector includes a housing having an interior in which a pair of resilient valve elements and a plunger mechanism are located. One valve element, e. g. , a disk-like member, has a small diameter opening therein. The other valve element, e. g. , a duck-bill valve elements, includes a normally closed, but openable, aperture therein. The plunger mechanism includes a tubular member having an outer diameter which is smaller than the diameter of the opening in the one valve element. The tubular member is arranged to be moved into and out of the opening in the one valve member and into and out of the aperture in the other valve element. The tubular member has a central passageway arranged to enable the elongated member to be readily extended therethrough for location at a desired position within the body of the being.

International Classification:

A61M 2500

US Classification:

604213

Abstract:

A needleless device for introducing or withdrawing a fluid to/from the vascular system of a being. The device includes first and second housing sections movably connected with respect to each other and which define a hollow interior in which a pair of resilient valve elements are located. The first housing section includes a first luer fitting for connection to an input line. The second housing section includes a second luer fitting for connection to an output line. A tubular plunger is located within the device and is arranged, when the housing sections are in a first position, to be automatically extended through a first valve element if the input line is connected to the first luer fitting, so that a liquid can be forced from the input line through the device to the output line. When the housing sections are in the first position and the input line disconnected from the first luer fitting, the tubular plunger is retracted out of both valve elements so that the device is fully occluded. The housing sections are movable to a second position with the input line connected to the first luer fitting, whereupon the tubular plunger is extended through both valve elements to provide free fluid communication between the input and output lines.
