Abstract:
An ear module with an interior lobe (200) housing a speaker (58) and adapted to fit within the Concha (103) of the outer ear, and an exterior lobe (300) housing data processing resources, includes a compressive member (202) coupled to the interior lobe (200) and providing a holding force between the anti-helix (101) and the forward wall (108) of the ear canal (102) near the tragus (104). The interior lobe (200) extends into the exterior opening (110) of the ear canal (102), and includes a forward surface (210) adapted to fit against the forward wall (108) of the ear canal (102), and a rear surface (211) facing the anti-helix (101). The width of the extension (201) (in a dimension orthogonal to the forward surface (210) of the extension (201)) between the forward surface (210) and the rear surface (211) from at least the opening of the ear canal (102) to the tip (203) of the extension (201) is substantially less than the width of the ear canal (102), leaving an open air passage (250).
Abstract:
Apparatus for directly stimulating a tympanic membrane or other acoustic member comprising a support with a plurality of activatable elements. The support can be mounted on the tympanic membrane and the activatable elements are distributed on the support to provide a distributed vibration to the tympanic membrane.

Abstract:
Lung volume reduction is performed in a minimally invasive manner by isolating a lung tissue segment, optionally reducing gas flow obstructions within the segment, and aspirating the segment to cause the segment to at least partially collapse. Further optionally, external pressure may be applied on the segment to assist in complete collapse. Reduction of gas flow obstructions may be achieved in a variety of ways, including over inflation of the lung, introduction of mucolytic or dilation agents, application of vibrational energy, induction of absorption atelectasis, or the like. Optionally, diagnostic procedures on the isolated lung segment may be performed, typically using the same isolation/access catheter.
Abstract:
An ear module, which can be selectively worn on either left or right ear, comprises an interior lobe, adapted to fit within the concha, comprising a speaker and a compressive member/cover assembly. The compressive member/cover assembly is positionable, typically rotatable, relative to the remainder of the inner lobe between left and right ear orientations to permit the ear module to be worn on either the left or the right ear. A method for improving the quality of sound emanating from an ear module includes selecting the sound bore within the ear module to help improve the frequency response of the ear module so that the ear module has a resonant peak near 2.7 kHz and a maximum 20 dB decrease in high frequency response as measured at 5 kHz from the average frequency response as measured at 500 Hz, 800 Hz, and 1600 Hz.

Abstract:
The present invention provides systems, methods, devices and kits for assessing the level of pulmonary disease in individual lung compartments. A lung compartment comprises a subportion of a lung, such as a lobe, a segment or a subsegment, for example. By measuring individual lung compartments, the level of disease of the pulmonary system may be more precisely defined by determining values of disease parameters reflective of individual subportions or compartments of a lung. Likewise, compartments may be separately imaged to provide further measurement information. Once individual compartments are characterized, they may be compared and ranked based on a number of variables reflecting, for example, level of disease or need for treatment. Such comparison may be aided by simultaneous display of such variables or images on a visual display. Further, the same tests may be performed on the lung as a whole or on both lungs and to determine the affect of the diseased lung compartments on the overall lung performance. In addition, the diseased lung compartments may be temporarily isolated and the measurement tests performed to determine the affect of the isolation on overall lung performance. As a result, the most beneficial treatment options may be selected.
Abstract:
Minimally invasive systems and methods are provided for diagnosing conditions in target lung compartments. Using catheters capable of isolating the target lung compartments and measuring one or more of collateral ventilation, pressure, flow rate, and volume, conditions such as hyperinflation, compliance, gas exchange including oxygen uptake, directionality of collateral channels, blood flow, and blood flow per unit lung volume may be assessed.
Abstract:
An electrosurgical working end and method for obtaining a tissue sample for biopsy purposes, for example, from a patient's lung or a liver. The working end provides curved jaw members that are positioned on opposing sides of the targeted anatomic structure. The working end carries a slidable extension member that is laterally flexible with inner surfaced that slide over the jaw members to clamp tissue therebetween. As the extension member advances, the jaws compress the tissue just ahead of the advancing extension member to allow the laterally-outward portion of the extension member to ramp over the tissue while a cutting element contemporaneously cuts the tissue. By this means, the transected tissue margin is captured under high compression. The working end carries a bi-polar electrode arrangement that engages the just-transected medial tissue layers as well as surface layers to provides Rf current flow for tissue welding purposes that is described as a medial-to-surface bi-polar approach.
