Abstract: An endolumenal for delivering and positioning an endolumenal expandable prosthesis for a bifurcation is provided. The endolumenal device includes a guidewire tracking device and an elongated body that has a central longitudinal axis and an expansion device configured to expand symmetrically relative to the central longitudinal axis. The guidewire tracking device comprises a single guidewire lumen disposed within a wall structure of the expansion device. The guidewire tracking device has at least three distal ports extending through the wall structure of the expansion device. The guidewire lumen includes a distal apical port in an approximately central position relative to the expansion device, considered in cross section at right angles to the central longitudinal axis.

Abstract: An endolumenal device (1) for delivering and deploying an endolumenal expandable prosthesis (6) at a bifurcation provided with a main conduit and at least a secondary conduit, comprises an elongated body (2) having a proximal end portion (4) and a distal end portion (3); the distal end portion (3) comprising expansion means (5) having a longitudinally extended active portion removably engageable with the prosthesis (6). Said active portion of the expansion means is longitudinally associated to the body in order to expand said prosthesis eccentrically from one side with respect to the body, in order to leave free from said expanded active portion the other side of the body. The device further is provided with guidewire tracking means (11).

Abstract: A navigation guide wire has a proximal portion with a first flexural rigidity, a distal portion with a second flexural rigidity greater than or equal to the first flexural rigidity, and an intermediate potion with a third flexural rigidity substantially less that both said first and second flexural rigidities. This allows a considerable direction change between said proximal and distal portions.

Abstract: A carrier catheter (20) for the introduction and positioning or changing of one or more guidewires (GW1, GW2, GW3) or interventional devices in a vessel V in the body of a subject. The catheter (20) includes an elongated, thin flexible body (22) having a primary lumen (24) and ancillary lumens (26, 28). Each lumen has an opening at the proximal end and an opening (30, 32, 34) at the distal end to permit a guidewire or device to extend through and exit the lumen. The openings at the distal ends of the lumens are positioned so that the respective guidewires or interventional devices can exit the lumens at different locations along the distal end of the catheter. One introduction of the device allows the deployment of any combination of multiple guidewires and interventional devices. The catheter can be used for a rapid replacement of an indwelling catheter or rapid replacement of a dedicated guidewire.

Abstract: Endolumenal device for delivering and positioning an endolumenal expandable prosthesis for a bifurcation between a principal conduit and at least one secondary conduit, comprising an elongated body having a proximal end portion and a distal end portion. The distal end portion of the elongated body comprises expansion device. Guidewire tracking device extend at least partially along said elongated body and comprise at least one pair of guidewire lumens. At least one of said guidewire lumens extends at least partially remaining attached to the wall of said expansion device.
