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.
Claims22
An exoskeleton device for assembly with a balloon catheter, comprising:
- an expandable section positionable over an expander of an expandable instrument, the expandable section including a plurality of struts, each strut extending along a length of the expandable section with the plurality of struts being positioned around a circumference 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, each slit of the pair of parallel slits defining the section of a strut of the plurality of struts from an adjacent section of an adjacent strut of the plurality of struts, an arrangement of slits of the expandable section rendering the expandable section radially expandable.
An exoskeleton device for assembly with a balloon catheter, comprising:
- an expandable section positionable over an expander of an expandable instrument, the expandable section including a plurality of rows of slits arranged around a circumference of the expandable section, each row of the plurality of rows of slits including a series of slits arranged along a generator of the circumference of the expandable section, each slit of the series of slits of each row of the plurality of rows of slits being offset relative to at least one slit of the series of slits of each adjacent row of the plurality of rows of slits.
A medical system, comprising:
- a guide wire insertable into a body of a subject to define a pathway between a cutaneous location on an outside of the body and a treatment site within the body;
- an exoskeleton device insertable into the body and advanceable through the body along the pathway, the exoskeleton device including an expandable section positionable at the treatment site, the expandable section including a plurality of struts that expand and at least partially rotate upon expansion of the expandable section;
- and
- an expandable instrument with an expander insertable into the expandable section of the exoskeleton device.
A method for scoring a surface within a body of a subject, comprising:
- introducing an exoskeleton device into the body of the subject, with an expandable section of the exoskeleton device being introduced to a location adjacent to a surface that is to be scored;
- introducing an expandable instrument through the exoskeleton device, including advancing an expander of the expandable instrument to an interior of the expandable section of the exoskeleton device;
- expanding the expander, including causing the expandable section of the exoskeleton device to expand, forcing the expandable section of the exoskeleton device against the surface that is to be scored, and scoring the surface.
