    摘要: The disclosed technology includes a medical probe including a tubular shaft, a contact force sensor assembly, a spine retention hub, and an expandable basket assembly. The contact force sensor can include a first bayonet mount portion and the spine retention hub can include a second bayonet mount portion to couple the spine retention hub to the contact force sensor by interlocking with the first bayonet mount portion. The expandable basket assembly can include a plurality of spines and at least one electrode coupled to each of the plurality of spines. Each of the plurality of spines can be configured to bow radially outward from the longitudinal axis when the expandable basket assembly is transitioned from a collapsed form to an expanded form.

    摘要: Apparatus for medical treatment, consisting of a probe and a processor. The probe has an insertion tube having a distal end configured for insertion into a body cavity of a living subject, and a basket assembly having multiple resilient spines coupled to the distal end of the insertion tube and joined together in a predefined form when the basket assembly is unconstrained by external forces. The probe also has a force sensor configured to output an indication of a force exerted on the basket assembly within the body cavity. The processor is configured to receive the indication of the force, to compute a constrained form of the basket assembly, different from the predefined form, responsively to the force, and to render to a display a graphical image representing the constrained form of the basket assembly.

    摘要: Medical apparatus includes an insertion tube configured for insertion into a body cavity of a patient and a distal assembly, including a plurality of spines having respective proximal ends that are connected distally to the insertion tube. Each spine includes a rib extending along a length of the spine, a flexible polymer sleeve disposed over the rib and defining a lumen running parallel to the rib along the spine, and one or more electrodes disposed on the sleeve and configured to contact tissue within the body cavity.
