US Classification:

6041641, 60416413, 60416503, 60416601, 604535, 604538

Abstract:

An access device places a medical article within a body space of a patient. The device has a needle that includes a needle body and hub. The device further includes a dilator coaxially disposed and slideable over the needle body and a medical article. A viewing space is disposed between the dilator and the medical article with at least one passageway or conduit connecting the viewing space with the interior bore of the needle body. The passageway is defined at least in part by openings through the sides of the needle and dilator. At least a portion of the conduit or passageway can be defined by one or more grooves between the needle and dilator. The device can further include a guidewire and an interlock between the guidewire and the needle and/or dilator. The device can further include one or more stops disposed between the guidewire and the needle and/or dilator to limit the extent to which the guidewire can be moved (e. g. , advanced) relative to the needle or inhibit such relative movement (e. g.

International Classification:

A61B 17/00

US Classification:

606 1

Abstract:

A wire for use with a vascular treatment device may have a proximal end, a distal end, and a main shaft extending therebetween. The distal end may have a distal free end and a first segment. The first segment may extend from the main shaft and may be biased to a first included angle that is defined between the main shaft and the first segment and less than 180 degrees.

Inventors:

Michael G. TAL - Great Neck NY, US

International Classification:

A61M 25/098

US Classification:

604508, 604529

Abstract:

An intravascular catheter may include a distal end for insertion and a proximal end. The distal end for insertion may terminate with a tip. It may define at least two openings, of which one is proximal-most in the distal end. The distal tip may include a first radiopaque marker that is discretely positioned at the proximal-most opening and radiographically distinguishes the proximal-most opening from the rest of the distal end. The distal tip may also include a second radiopaque marker that marks the tip.
