Abstract: Convertible travel tether devices for children. A convertible tether device includes a wearable accessory suitable for extended use by a relatively older child, a harness, and a detachable tether. The detachable tether is employed when the child is relatively younger, and the wearable accessory is worn by itself when the child is relatively older without use of the tether, thus providing extended use beyond the need to use the device as a harness. When a child is tethered, the appearance of the devices encourages a child to feel as if he or she is wearing a “big boy” or a “big girl” accessory.

Abstract: A microwave ablation assembly and method including a relatively thin, elongated probe (21) having a proximal access end (22) and an opposite distal penetration end (23) adapted to penetrate into bio-tissue (25). The probe (21) defines an insert passage (26) extending therethrough from the access end (22) to the penetration end (23) thereof. An ablation catheter includes a coaxial transmission line (28) with an antenna device (30) coupled to a distal end of the transmission line (28) for generating an electric field sufficiently strong to cause tissue ablation. The coaxial transmission line (28) includes an inner conductor (31) and an outer conductor (32) separated by a dielectric material medium (33). A proximal end of the transmission line (28) is coupled to a microwave energy source.
