Abstract:
An apparatus and methods for use are provided, where the apparatus includes: (a) a first catheter having a proximal end and a distal end, and wherein a distal portion of the first catheter includes a first one or more outlets, (b) a first tubular housing having a proximal end and a distal end, wherein the first tubular housing is coupled to the first catheter proximal to the at least one first outlet, (c) one or more pressure sensors coupled to the distal end of the first tubular housing, and (d) a second catheter having a proximal end and a distal end, wherein a distal portion of the second catheter includes a second one or more outlets, and wherein the distal end of the second catheter is configured to be positioned substantially within one of (i) the first catheter or (ii) a second tubular housing coupled to one or more of the first catheter and the first tubular housing, when the second catheter is in a first position.
Abstract:
An apparatus (10) for preventing stroke by occluding blood flow through a right carotid artery (12) and a left carotid artery (14) of a patient is provided. The apparatus has a first occluding catheter (16) that carries a first occluding balloon (18) that has an inflated configuration that occludes either the right carotid artery (12) or the left carotid artery (14). The apparatus also includes a second occluding catheter (20) that carries a second occluding balloon (22) that has an inflated configuration that occludes the other one of the right carotid artery or the left carotid artery that is not occluded by the first occluding balloon (18). An insertion device (58) may also be present to allow for insertion of the first (16) and second (20) occluding catheters.
Abstract:
A system for treating a bifurcation includes a first radially expandable stent and a second radially expandable stent. The first stent has a side hole and a plurality of lateral elements extending from the side hole. The second stent has a plurality of axial elements extending away from the proximal end of the second stent. The axial elements of the second stent interdigitate with the lateral elements of the first stent when both stents have been expanded.
Abstract:
Disclosed are a guide catheter (8, 8') for a branched stent delivery system and the branched stent delivery system, the guide catheter (8, 8') being used for introducing guide wires (5, 6, 7) into corresponding cavities of a branched blood vessel in order that stent branches (10, 11, 12) of a branched stent (9) are subsequently dragged into their corresponding branched blood vessel cavities, characterized in that the guide catheter (8, 8') is provided with at least one guide wire channel extending axially for guiding the guide wires (5, 6, 7), in that each of the guide wire channels is provided with an inlet (a, b, c) and a corresponding outlet (d, e, f) for the guide wires, and in that the guide catheter (8, 8') is axially split between the inlet for the guide wire (a, b, c) and the outlet for the guide wire (d, e, f) of the respective guide wire channels to form incisions (30, 100, 100', 100"), via which the respective guide wires (5, 6, 7) can be separated from the guide catheter (8, 8').
Abstract:
An improved balloon catheter structure includes a beveled distal tip, a reinforced distal portion, and an elastic or split sleeve over at least a portion of the balloon. The balloon may have a short length and a marker at its midline. The catheters are particularly useful for crossing through stent walls at vessel bifurcations.
