    摘要： A minimally invasive surgical instrument having an elongate stem extending between a proximal end which in use is located externally of an operating space and a distal end which in use is located within an operating space. At least a portion of the stem is malleable to facilitate manipulation of the stem in the operating space and then to maintain the stem in the manipulated position and/or orientation within the operating space. The instrument has an end effector at the distal end of the stem, the end effector having a proximal main body and distal operating means, such as graspers or cutters. The instrument has at least one joint for independent movement of the end effector main body in at least one direction relative to the distal end of the stem for enhanced degrees of freedom of the instrument.

    摘要： Apparatus and methods are disclosed for controlling deployment of a self-expanding support structure of a prosthetic valve that flares in a proximal direction upon implantation in vivo. A tubular delivery sheath having a side opening that proximally extends within a side wall thereof is used to deploy the prosthetic valve with the self-expanding support structure in a controlled manner. The prosthetic valve is distally advanced within a lumen of the delivery sheath with the self-expanding support structure held in a compressed delivery configuration within the delivery sheath lumen. The self-expanding support structure of the prosthetic valve is aligned with the side opening of the delivery sheath and the prosthetic valve is rotated relative to the delivery sheath whereby the self-expanding support structure is laterally released from the delivery sheath lumen through the side opening to gradually transition from the compressed delivery configuration to a flared deployed configuration.
