Abstract: A force transducer is coupled to a distal portion of a shaft of a surgical instrument. The force transducer includes proximal and distal portions, radial ribs, and a plurality of strain gauges. The radial ribs form a plurality of through passages. The surgical instrument further includes a flush manifold that receives a liquid from a proximal portion of the shaft, and that directs the liquid along a first subset of through passages of the plurality of through passages toward the distal portion of the force transducer. A plenum at the distal portion of the force transducer collects the liquid from the first subset of through passages and redirects the liquid back toward the proximal portion of the shaft along a second subset of through passages of the plurality of through passages different from the first subset of through passages.

Abstract: A support structure comprises a base joint coupling a proximal link of the support structure to a base. The proximal link is configured to rotate about a first axis associated with the base joint. The support structure further comprises a linkage mechanism. The linkage mechanism maintains an orientation of an instrument support relative to the base as the support structure is moved from a first configuration to a second configuration. In the second configuration, the support structure is rotated relative to the base about the first axis.

Abstract: A medical system includes an outer catheter comprising one or more first lumens, a sealing device coupled to the outer catheter, an inner instrument configured to be slideably deployed through one of the one or more first lumens and comprising one or more first sensors configured to detect one or more anatomical features below a surface of the anatomic passageway, one or more second sensors, and a processor. The processor is configured to detect bleeding into the anatomic passageway from outside the anatomic passageway using the one or more second sensors and disable advancement of the inner instrument when the one or more first sensors detect the one or more anatomical features. The one or more second sensors are configured to be positioned distal to the sealing device and mounted on the inner instrument near a distal end of the inner instrument.

Abstract: An apparatus for guiding an elongated flexible instrument comprises a variable-length support assembly. The variable-length support assembly includes a first end, a second end, a plurality of support member pairs, and a plurality of eyelets configured to receive the elongated flexible instrument. Each support member pair comprises a first support member linked to a second support member, and each of the plurality of eyelets is movably coupled to at least one of the plurality of support member pairs along a longitudinal central axis between the first end and the second end. The variable-length support assembly is configured to selectively transition from a compressed configuration to an expanded configuration along the longitudinal central axis, and the plurality of eyelets are adapted to support the elongated flexible instrument as the elongated flexible instrument is advanced along the longitudinal central axis. Each of the plurality of eyelets includes a tapered alignment member configured to contact a tapered alignment member of an adjacent eyelet to move the plurality of eyelets into alignment along the longitudinal axis as the variable length assembly transitions from the expanded configuration to the compressed configuration.
