Controlled steering functionality for implant-delivery tool

A first catheter has a first lumen therealong, a first-catheter proximal portion, and a steerable first-catheter distal portion that is transluminally advanceable to the heart. A second catheter has second lumen therealong, a second-catheter proximal portion, and a steerable second-catheter distal p...

Beschreibung
Zusammenfassung:	A first catheter has a first lumen therealong, a first-catheter proximal portion, and a steerable first-catheter distal portion that is transluminally advanceable to the heart. A second catheter has second lumen therealong, a second-catheter proximal portion, and a steerable second-catheter distal portion. The second catheter extends through the first lumen, such that the second-catheter proximal portion extends proximally out from the first-catheter proximal portion, the second-catheter distal portion extends distally out from the first-catheter distal portion, and within at least the first-catheter proximal portion, the first lumen and the second lumen are coaxial on a longitudinal axis. A first handle is coupled to the first-catheter proximal portion, and extends obliquely away from the first-catheter proximal portion at a nonzero angle with respect to the longitudinal axis. A second handle is coupled to the second-catheter proximal portion, and is disposed proximally from the first handle. Other embodiments are also described.
