Abstract
Devices and methods for exploiting intramural (e.g., subintimal) space of a vascular wall to facilitate the treatment of vascular disease, particularly total occlusions. For example, the devices and methods disclosed herein may be used to visually define the vessel wall boundary, protect the vessel wall boundary from perforation, bypass an occlusion, and/or remove an occlusion.

1-2. (canceled)
A system for facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein, the system comprising:
- an intramural orienting device having an elongate shaft with a central lumen extending therethrough to a distal opening, the device terminating at a distal tip configured for controlled deflection;
- a first actuation member connected to the distal tip and extending to a proximal end of the shaft for causing deflection of the distal tip upon movement of the first actuation member;
- an orienting element having a first collapsed configuration and a second expanded, substantially planar configuration;
- and
- a second actuation member connected to a portion of the planar orienting element and extending to a proximal end of the shaft for causing expansion of the orienting element upon actuation of the second actuation member.
A system for facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein, the system comprising:
- an intramural orienting device having an elongate shaft with a central lumen extending therethrough to a distal opening, the shaft including an inner layer and an outer layer;
- an orienting element at a distal end of the device including a pair of wings that extend along opposing sides of the device, the wings having a first collapsed configuration and a second expanded, substantially planar configuration;
- and
- each wing having a distal end and a proximal end, and wherein the wings exhibit the second expanded configuration upon moving the distal wing ends and the proximal wing ends closer together.
The system of 33, wherein the distal tip includes a pattern of rings formed with opposing longitudinal spines formed in the inner layer of the elongate shaft arranged to allow deflection only in a plane substantially perpendicular to the plane of the expanded orienting element.
A system for facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein, the system comprising:
- an intramural orienting device having an elongate shaft with a central lumen extending therethrough to a distal opening,
- an orienting element provided along the shaft and having a first collapsed configuration and a second expanded, substantially planar configuration;
- a bearing surface mounted to a portion of the elongate shaft along the orienting element;
- a first actuation member connected to the orienting element, extending distally around the bearing surface, and then proximally to a proximal end of the device;
- and
- a second actuation member connected to the orienting element and extending proximally to the proximal end of the device;
- wherein actuating the first actuation member causes controlled expansion of the orienting element, and actuating the second actuation member causes controlled collapse of the orienting element.
54-63. (canceled)
A system for facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein, the system comprising:
- an intramural orienting device having an elongate shaft with a lumen extending therethrough to a side port, the device terminating at a distal tip configured for controlled deflection;
- an orienting element having a first collapsed configuration and a second expanded, substantially planar configuration in a first plane;
- wherein the side port is located along the shaft proximal of the orienting element and facing a direction substantially perpendicular to the first plane;
- and
- wherein the distal tip is configured to allow deflection only in a second plane substantially perpendicular to the first plane such that upon deflection the tip is deflected either toward the side port or away from the side port.
A system for facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein, the system comprising:
- an intramural orienting device having an elongate shaft with a central lumen extending therethrough to a distal opening, the device terminating at a distal tip configured for controlled deflection;
- at least one actuation member connected to the distal tip and extending to a proximal end of the shaft for causing deflection of the distal tip upon movement of the actuation member;
- and
- an inflatable orienting member having a first collapsed configuration and a second expanded, substantially planar configuration in a first plane;
- and
- wherein the distal tip is configured to allow deflection only in a second plane substantially perpendicular to the first plane.
88-106. (canceled)
A system for facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein, the system comprising:
- an intramural orienting device having an elongate shaft with a central lumen extending therethrough to a distal opening, the device terminating at a distal tip configured for controlled deflection,
- at least one tension member connected to the distal tip at a first end and a point along the shaft at a second end;
- at least one inflation member;
- and
- wherein the at least one tension member is aligned with the inflation member such that deflection of the tip occurs upon inflation of the at least one inflation member.
A system for facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein, the system comprising:
- an intramural orienting device having an elongate shaft with a central lumen extending therethrough to a distal opening, the device terminating at a distal tip configured for controlled deflection;
- an inflatable member positioned proximal from the distal tip;
- at least one tension member connected to the distal tip at a first end such that displacement of the tension member causes deflection of the tip;
- separate lumens extending parallel to each other and in a planetary fashion around a circumference of the central lumen;
- and
- wherein the lumens located around the central lumen each contain a metallic element therein.
135-138. (canceled)
A device comprising:
- an elongate shaft defining a first planetary lumen;
- and
- a first balloon defining an interior in fluid communication with the first planetary lumen.
A catheter comprising:
- an elongate shaft defining a first planetary lumen;
- and
- a first wire disposed in the first planetary lumen.
A catheter, comprising:
- an elongate shaft;
- and
- a first inflation member that urges a distal portion of the elongate shaft to assume a deflected shape when the first inflation member is inflated.
