Abstract
An exoskeleton device is capable of being positioned over an expandable instrument, such as a balloon catheter. The exoskeleton device may include an expandable section that receives an expander of the expandable instrument. Expansion of the expander may cause the expandable section of the exoskeleton device to expand and force the expandable section of the exoskeleton device against a surface to be treated. The expandable section may be capable of scoring the surface against which it is forced.
Claims20
A medical device, comprising:
- an expandable section including a plurality of struts, each strut extending along a length of the expandable section, each strut of the plurality of struts including a plurality of sections, each section defined by a pair of parallel slits through the expandable section, an arrangement of slits of the expandable section rendering the expandable section radially expandable and each strut at least partially rotatable upon radial expansion of the expandable section.
A medical system, comprising:
- an expandable device insertable into a body and advanceable through the body along a pathway, the expandable device positionable at a treatment site, the expandable device including a plurality of slits defining a plurality of struts that expand and at least partially rotate upon expansion of the expandable device;
- and
- an elongated instrument that carries the expandable device along the pathway to the treatment site.
A method for treating a body of a subject, comprising:
- introducing an expandable device to a target location in the body of the subject;
- and
- expanding the expandable device, including causing at least a portion of the expandable device to expand with an arrangement of slits in the expandable section enabling portions of struts of the expandable section to move circumferentially apart from one another and to at least partially rotate, forcing at least a portion of the expandable device against a surface at the target location.
