    Abstract: Described herein is a sensing wire for locating a blood vessel in a patient. The sensing wire comprises a hollow, rigid tube including a lumen extending from a proximal portion to a distal portion, an ultrasonic sensor coupled to the distal portion of the tube, and a communication assembly positioned at the distal portion and coupled to the ultrasound sensor. Also described is a system for accessing and evaluating a blood vessel in a patient. The system comprises an access sensor wire, an access needle sized to receive the access sensor wire, and a second sensing wire configured to be positioned within the access needle. A method is also disclosed for accessing a blood vessel with an introduction needle, where a short access sensing wire is replaced by a much longer second sensing wire after the needle is positioned in the vessel.

    Abstract: The invention generally relates to treatment of fistulas and abscesses and specifically to an all-in-one treatment device. The invention provides an aspiration catheter with imaging capabilities that can also deploy a blocking device, thereby providing an all-in-one treatment device for treating a fistula or an abscess. The device is inserted into an abscess and its imaging capabilities can be used to guide the device to a treatment site. A clogging device can be deployed from the device to prevent draining into, or out of, the abscess. In certain aspects, the invention provides a device for aspirating an abscess or fistula that includes a catheter having an extended body with a lumen therein, an imaging device such as an ultrasonic transducer disposed at a distal portion of the catheter, and a clogging device deployable from the catheter.

    Abstract: The present disclosure provides various embodiments of methods of forming a tapering distal tip for a catheter. An exemplary method includes providing a mandrel and a holding hypotube, placing a tip first material with a first outer diameter over the mandrel and the hypotube, placing a tip second material with a second outer diameter over the mandrel and under the first material, placing a shrink tube of heat-shrink material around at least a junction of the first material and second material, heating the shrink tube, cooling the first material and second material, and removing the shrink tube and the hypotube. The first outer diameter is greater than the second outer diameter.
