  • Publication number: 20200196841
    Abstract: A protective cover set for a medical probe that includes a joint that seals both a moisture resistant probe cover and a surrounding wrapper that provides a barrier against microbial intrusion into the space between the outer wrapper and the probe cover. The sealed joint fixes the probe cover in place in relation to the outer wrapper. In some examples, the sealed joint secures a prefabricated probe cover with a three-dimensional non-planar shape in relation to the outer wrapper.

  • Publication number: 20200089024
    Abstract: A deformable membrane assembly comprises an at least partially flexible fluid-filled envelope, one wall of which is formed by an elastic membrane that is held around its edge by a resiliently bendable supporting ring, a fixed support for the envelope and selectively operable means for causing relative movement between the supporting ring and the support for adjusting the pressure of the fluid in the envelope, thereby to cause the membrane to deform. The bending stiffness of the ring varies round the ring such that upon deformation of the membrane the ring bends variably to control the shape of the membrane to a predefined form. The moving means comprise a plurality of ring-engaging members that are arranged to apply a force to the ring at spaced control points.
