Catheters with guidewire adaptors and related methods

A catheter assembly comprising:

• a catheter tube attached to a catheter hub and a needle attached to a needle hub, wherein the needle is located in a lumen of the catheter tube and a needle tip of the needle projects out a distal opening of the catheter tube;
• an adaptor having a body comprising a base, a tip, and a bore extending through the body, the base having a base bore section and the tip having a tip bore section, the tip located in a proximal opening of the needle hub;
• and
• a guidewire dispenser having a frame with a plurality of branches, a connection tip at a first branch of the plurality of branches located inside the base bore section of the adaptor;
• and
• wherein a guidewire extends through a second branch of the plurality of branches and in through the connection tip at the first branch.

A catheter assembly comprising:

• a catheter tube attached to a catheter hub and a needle having a needle tip attached to a needle hub, wherein the needle projects through the catheter tube and the needle tip disposed distally of a distal opening of the catheter tube;
• an adaptor having a body with an exterior surface and an interior surface defining a bore, the body further having a base having a base bore having a valve chamber and a valve comprising at least one slit and two flaps located in the valve chamber and a tip having a guidewire passage, said tip located in a proximal opening of the needle hub;
• and
• a guidewire dispenser having a tip disposed in the bore of the adaptor and a guidewire having a first end disposed in the bore of the adaptor.

An adaptor for use to guide a guidewire through a needle lumen comprising:

• a body comprising a base, a tip, and a bore extending through the body;
• the base having a base bore section and the tip having a tip bore section;
• at least one of a cannula channel at the tip having a plurality of generally straight sides with two adjacent plurality of straight sides connected to one another by an arcuate connecting portion and sized to receive a needle shaft and a valve comprising a wall having at least one slit positioned in the base bore of the base;
• wherein the base comprises a proximal opening sized and shaped for receiving a tip of a guidewire dispenser and a first engagement structure for engaging a second engagement structure on the tip of the guidewire dispenser.

A guidewire dispenser comprising:

• a frame with a plurality of branches, including a first branch and a second branch;
• a connection tip at the first branch, said connection tip comprising a lumen;
• a guide bracket at the second branch and a lumen formed through guide bracket, said guide bracket comprising a socket;
• a tubing having a first free end and a second free end, said first free end located in the socket and said second free end held by a retaining clip or by socket located on a third branch;
• a guidewire having a length with a first free end and a second free end, said guidewire located in said tubing and extending through the socket at the second branch and into the lumen of the connection tip;
• and
• wherein the guidewire is exposed between the first branch and the second branch.
