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.
Claims20
An orienting device, comprising:
- an elongate shaft including a central guidewire lumen extending from a proximal end of the elongate shaft to a distal end of the elongate shaft;
- a first balloon disposed proximal of the distal end of the elongate shaft, the first balloon including a first inflatable portion configured to extend outward from a first side of the elongate shaft in an inflated configuration;
- a second balloon disposed proximal of the distal end of the elongate shaft, the second balloon including a second inflatable portion configured to extend outward from a second side of the elongate shaft opposite the first side in an inflated configuration;
- and
- a steerable tip disposed at the distal end of the elongate shaft, wherein the steerable tip is configured to be articulated in vivo;
- wherein the elongate shaft includes a plurality of lumens arranged around the central guidewire lumen;
- wherein a first tension member is slidably disposed within a first lumen of the plurality of lumens and has a first distal end fixedly attached to the steerable tip, and a second tension member is slidably disposed within a second lumen of the plurality of lumens and has a second distal end fixedly attached to the steerable tip;
- wherein the first tension member and the second tension member are configured to selectively deflect the steerable tip.

- a first inflatable portion configured to extend outward from a first side of the elongate shaft in an inflated configuration;
- a second inflatable portion configured to extend outward from a second side of the elongate shaft opposite the first side in an inflated configuration;

- and
- a first tension member slidably disposed within a first lumen of the elongate shaft extending along the guidewire lumen, the first tension member has a first distal end fixedly attached to the steerable tip;
- wherein the first tension member is configured to selectively deflect the steerable tip while the first inflatable portion is in the inflated configuration and the second inflatable portion is in the inflated configuration.

- a first balloon disposed proximal of the distal end of the elongate shaft, the first balloon including a first inflatable portion configured to extend outward from a first side of the elongate shaft in an inflated configuration;
- a second balloon disposed proximal of the distal end of the elongate shaft, the second balloon including a second inflatable portion configured to extend outward from a second side of the elongate shaft opposite the first side in an inflated configuration;
- and
- a bi-directional tip disposed at the distal end of the elongate shaft, wherein the bi-directional tip is configured to be articulated in vivo in only two directions from a central longitudinal axis of the central guidewire lumen;
- wherein the elongate shaft includes a plurality of lumens arranged around the central guidewire lumen;
- wherein a first tension member is slidably disposed within a first lumen of the plurality of lumens and has a first distal end fixedly attached to the bi-directional tip, and a second tension member is slidably disposed within a second lumen of the plurality of lumens and has a second distal end fixedly attached to the bi-directional tip;
- wherein the first tension member is configured to selectively deflect the bi-directional tip in a first direction and the second tension member is configured to selectively deflect the bi-directional tip in a second direction opposite the first direction.
