Abstract
An intravascular device for providing feedback to an operator during use and methods of providing the same as disclosed. A catheter tube extends from a handle assembly. An expandable portion is connected to the catheter tube and is selectively movable between a first position and an expanded position. A feedback device provided at the expandable portion provides the operator with the feedback.
Claims20
An intravascular device for providing feedback to an operator during use, said intravascular device comprising:
- a handle assembly;
- a control element located at said handle assembly:
- a catheter tube extending from said handle assembly;
- an expandable portion connected to said catheter tube and comprising a first common attachment component, a second common attachment component, and a plurality of struts, each extending between the first common attachment component and the second common attachment component, wherein said expandable portion is selectively movable between a first position and an expanded position where the struts bow outwardly, and wherein the longitudinal axis of each of the struts extends along a longitudinal axis of the expandable portion when said expandable portion is in the first position;
- an incising element an outer surface of one for the plurality of struts and having a longitudinal axis extending along a longitudinal axis of a respective one of the struts;
- an inner sleeve attached to said control element at a first end, wherein sliding movement of said inner sleeve within said catheter tube moves said expandable portion between said first position and said expanded position;
- a lip member connected to said inner sleeve and configured to accommodate a guide wire:
- a limiter interposed between said second attachment point and said tip member;
- and
- one or more feedback devices comprising at least one hardness sensor provided at a mid-portion of an outer surface of said expandable portion and at least one pressure sensor connected to said limiter.
An intravascular device for providing feedback to an operator during use, said intravascular device comprising:
- a handle assembly;
- a catheter tube extending from said handle assembly;
- an expandable portion comprising struts extending between a first common attachment component connected to said catheter tube and a second common attachment component, wherein said expandable portion is selectively movable between a first position and an expanded position whereby said struts are moved outward;
- an inner sleeve extending within the expandable portion, said inner sleeve configured to accommodate a guide wire;
- a tip member located distal to the expandable portion along the inner sleeve and configured to accommodate the guide wire;
- a feedback device provided at said expandable portion;
- and
- a limiter interposed between said second common attachment component of said expandable portion and said tip member.
An intravascular device for providing feedback to an operator during use, said intravascular device comprising:
- a handle assembly;
- a catheter tube extending from said handle assembly;
- an expandable portion connected to said catheter tube, said expandable portion comprising a balloon which is selectively inflatable for moving said expandable portion between a first position and an expanded position;
- a jacket provided circumferentially about a midline of said balloon and configured for expansion with the balloon;
- and
- harness and/or pressure sensors spaced apart along said jacket.
