Title:
SPIRAL GUIDEWIRES
Document Type and Number:
WIPO Patent Application WO/2024/013703
Kind Code:
A3
Abstract:
A cardiac guidewire (20) is provided that is advanceable to a target cardiac site (10). The cardiac guidewire (20) is shaped so as to define an elongate portion (22), which is straight when unconstrained, and a spiral distal portion (24), which extends from and is supported by a distal end (26) of the elongate portion (22). The cardiac guidewire (20) is configured such that the spiral distal portion (24), when in an unconstrained resting state, is shaped as a spiral (30) that (a) spirals radially outward at an increasing distance from the distal end (26) of the elongate portion (22) so as to define an outer turn (32), and (b) has a zero or non-zero height. The cardiac guidewire (20) is further configured such that pushing of the elongate portion (22) in a distal direction (34), when the outer turn (32) of the spiral (30) engages cardiac tissue (36) at the target cardiac site (10), changes the height of the spiral (30) and deforms the spiral (30). Other embodiments are also described.
