Abstract
Assemblies and methods for capturing a guidewire advanced through a blood vessel in a retrograde direction are disclosed. An assembly can include a constraining catheter and a capture catheter. The constraining catheter can include a first longitudinal member and a tubular member; the tubular member can be eccentrically coupled with a distal end portion of the first longitudinal member. The capture catheter can include a second longitudinal member and a funnel member; the funnel member can be eccentrically coupled with a distal end portion of the second longitudinal member. The funnel member can be moved between a collapsed configuration and an expanded configuration through relative movement between the first and second longitudinal members. In the collapsed configuration, at least a portion of the funnel member is disposed within a lumen of the tubular member. In the expanded configuration, the portion of the funnel member projects from an end of the tubular member.
