Abstract: Catheter actuators providing a mechanical advantage are disclosed. The actuators include a pull wire arm guide plate and a drive wheel attached around the pull wire arm guide plate and pivotable relative to the guide plate, the drive wheel comprising at least one thumb boss for pivoting the drive wheel about a drive wheel axis of rotation. The drive wheel mechanically engages at least one pull wire arm slidably mounted in a pull wire arm channel in the pull wire arm guide plate. A mechanism transfers drive wheel input into longitudinal motion of the at least one pull wire arm. The mechanism may include, for example, a pin pushing against a bendable pushing member riding in an arcuate pin groove in a top surface of the guide plate, or a pin pushing against a surface of a cam arm pivotably mounted on the top surface of the guide plate.

Abstract: An apparatus for detecting deformation of an elongate body may comprise a light source configured to sequentially provide light of multiple frequencies, an optical receiver configured to receive light from the light source, and a filter disposed between the light source and the optical detector. The filter may comprise multiple segments, each of the segments configured to filter light at one of the frequencies so as to alter the amount of light incident on said optical receiver. A total amount of light detected by the optical receiver may change during the sequence so as to be indicative of deformation of the elongate body.

Abstract: A system for controlling delivery of ablation energy by an ablation catheter to tissue in a body is provided. The system includes an electronic control unit configured to determine, responsive to a measurement signal from the ablation catheter, a value for a characteristic associated with the delivery of ablation energy to the tissue. In one embodiment, the characteristic is the degree of contact between the ablation catheter and the tissue. The unit is further configured to generate a control signal, responsive to the determined value of the characteristic, to control an amount of energy delivered from an ablation delivery element on the ablation catheter to the tissue. The amount of energy varies in response to the determined value of the characteristic when the determined value of the characteristic meets a predetermined condition relative to a threshold value for the characteristic.

Abstract: A medical device, such as an introducer, includes a shaft having a lumen therethrough. A distal region of the shaft includes both a fixed curve region and a steerable region. According to certain aspects of the disclosure, the fixed curve region is more proximal than the steerable region. The fixed curvature of the distal region is selected to facilitate positioning of the distal end of the medical device in the general vicinity of a target, such as the left atrial appendage, while the steerable region allows for “fine tuning.” The lumen of the shaft is a large bore, typically on the order of about 12F to about 14F, to facilitate passage of larger medical devices, including left atrial appendage occlusion devices.
