The first tubular member is disposed to cover (i) a contact portion where the first core shaft and the second core shaft are arranged opposite to each other so that their central axes coincide, and (ii) a part of each of the first core shaft and the second core shaft, the part being adjacent to the contact portion. The second tubular member, having a tubular shape, covers at least the first tubular member and is fixed to both the first core shaft and the second core shaft.

Abstract: Determining lung capacity of includes capturing an audio waveform of the user performing an utterance presented to a user. A video of the user performing the utterance can be captured. The captured audio waveform and the video are analyzed for compliance. Based on the audio waveform, an indicator of respiratory function is determined. The indicator is compared with a reference indicator to determine health of the user. A machine learning model such as neural network can be trained to predict the indicator of the respiratory function based on input features comprising audio spectral and temporal characteristics of utterances. Determining the indicator or respiratory function can include running the trained machine learning model.

The valve sizer can include a handle, a shaft extending distally from the handle, a sizing element coupled to the distal end of the shaft, the sizing element being movable between a first retracted position and a second expanded position, and a sizer cover. The sizer cover can be formed from a continuous sheet of material configured to surround at least a portion of the sizing element of the heart valve sizer so as to guard against entanglement of the sizing element with structures of a human heart.

The systems include a device for measuring the stiffness of the bone in vivo and a data analyzer to determine a complex compliance frequency response function Y(f) and an associated complex stiffness frequency response function H(f).

Abstract: Many treatments of skin cancer need an accurate assessment of the margins of the tumor. Spectrally-encoded optical polarization imaging improves upon the demarcation of skin cancer such as keratinocytic carcinomas. When the clinician can outline the clinical boundary of each lesion, surgery and other treatments can be more efficient and effective. Optical images of the lesions are acquired at various wavelengths, then spectrally-encoded. Spectral-encoding of the images minimizes the impact of background pigmentation and vascularization so that the tumor can be accurately visualized.

Abstract: A blood pressure cuff includes a smaller patient bladder extending laterally across the cuff and longitudinally along a minor portion of second and fourth perimeter segments of the cuff. The cuff also includes a larger patient bladder extending laterally across the cuff and longitudinally along a major portion of the second and fourth perimeter segments of the cuff. The smaller patient bladder and the larger patient bladder are fluidically isolated from each other. A small patient port projects through the smaller patient bladder on a first side of the cuff. A large patient port projects through the larger patient bladder on a second side of the cuff which is transversely opposite the first side.

Abstract: Survivors of central nervous system injury commonly present with spastic hypertonia. The affected muscles are hyperexcitable and can display involuntary static muscle tone and an exaggerated stretch reflex. These symptoms affect posture and disrupt activities of daily living. Symptoms are typically measured using subjective manual tests such as the Modified Ashworth Scale; however, more quantitative measures are necessary to evaluate potential treatments. The hands are one of the most common targets for intervention, but few investigators attempt to quantify symptoms of spastic hypertonia affecting the fingers. An Isometric Force Pillow (IFP) is provided herein to quantify involuntary grip force. This lightweight, computerized tool provides a holistic measure of finger flexion force and can be used in various orientations for clinical testing and to measure the impact of assistive devices.
