A floating fastener comprises a retainer and a captive nut held within a cavity of the retainer. The nut is star-shaped with four points spaced equally apart and with four valleys on the periphery of the nut between the points creating the overall star-shape of the nut. Likewise, the cavity in the retainer corresponds to the shape and contour of the nut but sized so that there is a substantial gap between them. Permissible lateral float of the nut can be maximized by employing a particular angularity of the sides of the valleys in relation to other dimensions of the fastener.

Self-clinching floating fastener

A medical injection system includes an elongate injection apparatus and an actuator apparatus. The actuator apparatus includes a fitting for coupling the actuator apparatus to a delivery catheter and a reversible gripping means to grip the injection apparatus; the gripping means is included in a plunger that is slideably engaged with the fitting and directs the injection apparatus through a fitting lumen and through a catheter lumen, when the fitting is coupled to the catheter.

Modular medical injection system

A catheter and a guidewire exchange system includes a catheter and a guide member. The catheter includes a lumen extending through the shaft and sized to receive the guidewire, and a longitudinal guideway enabling transverse access from the shaft exterior surface to the lumen. The guide member includes a housing, a catheter passageway extending through the housing and adapted to slidably receive the catheter, a guidewire passageway extending from one end of the housing into the catheter passageway and including a tube adapted to merge the guidewire transversely through the guideway and into the first lumen, a rigid nose cone attached to the housing and having an aperture extending therethrough that is continuous with the catheter passageway and adapted to slidably receive the catheter, and a first gasket positioned in line with the catheter passageway and tightenable to impede catheter movement through the catheter passageway.

Multi-exchange catheter guide member with improved seal

A catheter and guide wire exchange system including a catheter that has a guide wire lumen with a guide way extending along a length of the proximal shaft. A guide member is slidably disposed about the proximal shaft for directing a guide wire into or out of the guide way and the guide wire lumen. A transition section joins the trilumen proximal shaft to a coaxial distal shaft.

Catheter and guide wire exchange system with improved proximal shaft and transition section

A catheter and guide wire exchange system including a catheter having a guide wire lumen with a guide way extending along the length of a stiffened proximal shaft portion, and a guide member slidably disposed about the proximal shaft for directing a guide wire into or out of the guide way and the guide wire lumen. The guide member may be slid along the proximal shaft portion and the guide wire in zipper-like fashion so that the guide wire is contained within the guide wire lumen distal to the guide member and with the guide wire and catheter being separated proximal of the guide member.
