Disclosed herein are methods and apparatuses for the transmission of audio information from a bone-conduction headset to a user. The bone-conduction headset may be mounted on a glasses-style support structure. The bone-conduction transducer may be mounted near where the glasses-style support structure approach a wearer's ears. In one embodiment, an apparatus has a bone-conduction transducer with a diaphragm configured to vibrate based on a magnetic field. The magnetic field being based off an applied electric field. The apparatus may also have an anvil coupled to the diaphragm. The anvil may be configured to conduct the vibration from the bone-conduction transducer. Additionally, the anvil may be anvil may include at least one passage configured to enable the anvil to be physically coupled to the diaphragm. Thus, the anvil may be coupled to the diaphragm after the anvil is positioned on the diaphragm.

A head-wearable device includes a center support extending in generally lateral directions, a first side arm extending from a first end of the center frame support and a second side arm extending from a second end of the center support. The device may further include a nosebridge that is removably coupled to the center frame support. The device may also include a lens assembly that is removably coupled to the center support or the nosebridge. The lens assembly may have a single lens, or a multi-lens arrangement configured to cooperate with display to correct for a user's ocular disease or disorder.

A stent includes a first flaring portion including first and second sets of cells that flare outwardly when the stent is expanded from a contracted to a flared condition, and a second main portion connected to the first flaring portion. During use, the stent is introduced into a main vessel in the contracted condition and positioned with the first portion adjacent an ostium. The first portion is flared, causing first struts of the first set of cells to move from an axial towards a radial and partial circumferential orientation and causing second struts of the second set of cells to move from an axial towards a radial orientation. The second portion resists expansion when the first portion is flared. The stent is expanded further such that the second portion expands within the branch body lumen, and the first and second struts move towards a more circumferential orientation.

Devices and methods for retrieving an intravascular device disposed within a blood vessel are disclosed. A retrieval device in accordance with an illustrative embodiment of the present invention includes an elongated member, a retractable dilator tip, and a retraction wire operatively coupled to the retractable dilator tip. The retraction wire can be connected to a slide mechanism that can be actuated by the physician to expose an interior cavity of the retrieval device that receives the intravascular device therein. In some embodiments, the retrieval device can include an inflatable balloon cuff, a tip deflection wire, and/or other means to facilitate advancement of the retrieval device beyond obstructions within the blood vessel.
