The present disclosure relates to tissue cutting assemblies that can be used for cutting through a tissue. In an example, the tissue cutting assembly comprises a nosecone assembly and a cutting member extending therethrough. The nosecone assembly comprises a rigid member with a slot, and a flexible member positioned distally to, and attached to, the rigid member. The cutting member comprises a tubular body axially movable within a channel of the nosecone assembly, and a blade radially extending from the tubular body, configured to axially move between a concealed position, in which the blade is entirely concealed inside the slot, and an exposed position, in which a sharp edge of the blade is exposed from the nosecone assembly and can be further advanced to cut through the target tissue.
