Abstract

Abstract A steerable distal support system for accessing stenosis, partial occlusions, or complete occlusions within a body lumen. The steerable distal support system generally includes an elongate member that comprises a proximal portion, a more flexible intermediate portion and a deflectable distal tip. The deflectable distal tip is at a distal end of the elongate body to facilitate directionality and positioning of the steerable distal support system to the target site. Optionally, an expandable centering assembly may be disposed on the steerable support assembly to center and anchor the steerable support assembly within the body lumen.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 115 words
A steerable distal support system comprising: an elongate body comprising a proximal portion, an intermediate portion, and a deflectable distal tip integrally formed by slots on the body; an expandable centering element integrally formed by slots in the elongate body proximal of the deflectable distal tip, and which is configured for centering the portion of the elongate body when the centering element is in an expanded configuration; a first pull wire fixedly attached to the distal tip of the elongate body, wherein pulling of the first pull wire deflects the distal tip; and a second pull wire attached to the expandable centering element, wherein pulling of the second pull wire expands the expandable centering element.
Claim 2
Dependent Claim 115 words
A steerable distal support system comprising: an elongate body comprising a proximal portion, an intermediate portion, and a deflectable distal tip integrally formed by slots on the body; an expandable centering element integrally formed by slots in the elongate body proximal of the deflectable distal tip, and which is configured for centering the portion of the elongate body when the centering element is in an expanded configuration; a first pull wire fixedly attached to the distal tip of the elongate body, wherein pulling of the first pull wire deflects the distal tip; and a second pull wire attached to the expandable centering element, wherein pulling of the second pull wire expands the expandable centering element.
Claim 3
Dependent Claim 57 words
The steerable distal support system of claim 1 , wherein the slots of the expandable centering element define a plurality of expandable struts, wherein in an expanded configuration a portion of the struts expand radially outward from the elongate body and contact an inner surface of a body lumen and to open said slots between the struts.
Claim 4
Dependent Claim 17 words
The steerable distal support system of claim 2 wherein the slots between the struts are substantially S-shaped.
Claim 5
Dependent Claim 17 words
The steerable distal support system of claim 1 wherein the elongate body comprises a laser etched hypotube.
Claim 6
Dependent Claim 20 words
The steerable distal support system of claim 1 , wherein slots of the expandable centering element comprise a spiral coil.
Claim 7
Dependent Claim 44 words
The steerable distal support system of claim 5 , wherein the spiral coil comprises a decreasing pitch distally along an intermediate portion of the expandable centering element, wherein the decreasing pitch creates an increased flexibility in the intermediate portion of the expandable centering element.
Claim 8
Dependent Claim 23 words
The steerable distal support system of claim 1 further comprising a radiopaque marker positioned at a distal end of the deflectable distal tip.
Claim 9
Dependent Claim 27 words
The steerable distal support system of claim 1 wherein the proximal portion, intermediate portion, expandable centering element, and deflectable distal tip are comprised of a single hypotube.
Claim 10
Dependent Claim 45 words
The steerable distal support system of claim 1 , further comprising at least either or both an inner liner and an outer liner coupled to at least a portion of at least one of an inner surface and an outer surface of the intermediate portion.
Claim 11
Dependent Claim 24 words
The steerable distal support system of claim 9 , wherein the inner liner is connected to at least a portion of the intermediate member.
Claim 12
Dependent Claim 27 words
The steerable distal support system of claim 1 , wherein the expandable centering element is configured for further stabilizing the elongate tubular member within a body lumen.
Claim 13
Dependent Claim 25 words
The steerable distal support system of claim 1 , wherein the expandable centering element and the deflectable distal tip are formed from separate interconnected sections.
