Abstract
Delivery systems with telescoping capsules for delivering prosthetic heart valve devices and associated methods are disclosed herein. A delivery system configured in accordance with embodiments of the present technology can include, for example, a delivery capsule having a first housing, a second housing slidably disposed within a portion of the first housing, and a prosthetic device constrained within the first and second housings. The delivery capsule can further include first and second chamber defined in part by the first and second housings. During deployment, fluid is delivered to the first chamber to move the first housing distally over the second housing, thereby releasing a portion of the prosthetic device. Subsequently, fluid is delivered to the second chamber such that the first and second housings move together in the distal direction to release a second portion of the prosthetic device.
