Abstract: A re-entry device for recanalization of a vessel using a subintimal technique. A catheter (10) includes a first inner lumen (14) extending to a distal end portion (12b) of the catheter, the distal end portion including an angled tip (20) having a distal open end (20a). An elongated stylet (24) is located in the first inner lumen, the stylet having an angled distal end portion (24a) forming a needle. An actuator (26) at a proximal end portion (12a) of the catheter is for advancing the stylet from a retracted position within the catheter to a deployed position projecting from the distal open end of the angled tip for penetrating a wall of the vessel.

Abstract: A catheter is provided for both crossing a lesion, such as a chronic total occlusion, in a vessel and performing percutaneous transluminal angioplasty thereupon. The catheter includes a shaft having a tapered tip adapted for being pushed into the lesion to advance through the lesion. An inflatable balloon is mounted on the shaft, which may be braided to provide enhanced pushability and kink-resistance. The inflatable balloon includes a proximal portion and a distal tapered portion connected to the tapered tip, and having a shallow taper. The taper of the distal tapered portion and the tapered tip may together create a continuous sloping transition from a distal end of the distal tapered portion to an adjacent portion of the tapered tip to facilitate crossing a lesion. The balloon may also be selectively inflated or deflated during crossing of the lesion, and ultimately used to compact the lesion when inflated.

Abstract: An adjustable interface device for connecting two components of a medical device includes an elongate body and an elongate member. The elongate body has a first end, a second end, an interior channel, and a side wall that surrounds the interior channel. The side wall defines a first connector portion adjacent the second end. The first connector portion attaches to a respective one of the components of the medical device. The elongate member has a head end portion and a shaft portion that longitudinally extends from the head end portion. The shaft portion is located at least partially in the interior channel of the elongate body. The shaft portion is configured to slidably move axially along the longitudinal axis to adjust a length of the adjustable interface device. The head end portion defines a second connector portion that attaches to another of the components of the medical device.

Abstract: Disclosed is an implantable medical device such as a port assembly including a catheter lock and one or more unique device identifiers (“UDIs”) of the catheter lock. The catheter lock is configured to fit over an end portion of a catheter over an outlet stem extending from a portion of the implantable medical device such as housing of a port. The one or more UDIs embedded in the catheter lock include machine-readable identification data for the implantable medical device. Also disclosed is a system including the implantable medical device and instructions stored in a memory of a computing device for execution by one or more processors. Methods related to the foregoing are additionally disclosed.
