Abstract
The disclosed technology includes an actuator subsystem for a medical probe, including an actuator, a detent, and at least one catch. The actuator is designed to move an end effector between expanded and collapsed configuration. As the actuator is moved, the catches, in conjunction with the detent, provide tactile feedback regarding a position of an end effector of the medical device.
Claims20
An end effector for a medical device, the end effector comprising:
- a unitary spine frame comprising:
- a proximal end, a distal end comprising a crown, and a plurality of spines integral with the crown, the plurality of spines being configured to bow radially outward from a longitudinal axis and to move between an expanded configuration and a collapsed configuration, the unitary spine frame defining a teardrop shaped profile in the collapsed configuration, the teardrop shaped profile having a bulbous distal region that tapers to a trailing proximal region, the bulbous distal region including the plurality of spines expanding outward with respect to the longitudinal axis from the crown in a proximal direction and the plurality of spines tapering toward the longitudinal axis for the smaller proximal region with a transition region between the bulbous distal region and the trailing proximal region;
- at least one electrode being disposed on each spine in the bulbous distal region;
- and
- at least two electrodes being disposed on each spine in the trailing proximal region.
2 more elements
A housing assembly for a medical device, the housing assembly comprising:
- a shell defining a cavity;
- an actuator slidable within the cavity along a longitudinal axis and configured to move an end effector between an expanded configuration and a collapsed configuration;
- a detent engaged with one of the shell and the actuator;
- and
- a first catch integrated with the other of the shell and the actuator and configured to selectively engage the detent, the engagement of the detent and the first catch providing tactile feedback regarding a collapsed configuration, an intermediate configuration, or an expanded configuration of the end effector.
2 more elements
A medical device comprising:
- a first shaft extending along a longitudinal axis and attached to an actuator;
- an end effector attached to the first shaft at a proximal end of the end effector and configured to move between an expanded configuration, an intermediate configuration, and a collapsed configuration;
- and
- a housing assembly comprising:
- an actuator attached to the first shaft and slidable along the longitudinal axis, sliding movement of the actuator sliding the first shaft and the proximal end of the end effector;
- a detent;
- and
- a first catch configured to selectively engage with the detent, the first catch being configured to provide tactile feedback that the end effector is in one of the expanded configuration, the intermediate configuration, and the collapsed configuration.
