  • Publication number: 20230148931
    Abstract: Implantable medical devices including a transseptal lead are described herein. The transseptal lead may be positioned or placed through the interatrial septum from the right atrium to the left atrium of a patient's heart and further through the mitral valve. The transseptal lead may include at least one left atrial electrode and at least one left ventricular electrode for sensing, among other things, left atrial and left ventricular electrograms, left atrial and left ventricular impedances, and cross mitral valve impedance.

  • Publication number: 20220023621
    Abstract: An implantable medical lead comprising a lead body defining a lumen. The lead body includes one or more tines substantially at a distal end of the lead body. An inner member extending within the lead body lumen is configured to rotate relative to the lead body and configured to cause a rotation of a dilator. The dilator is configured such that the rotation causes or enables a lateral translation of the dilator from a first position proximal to a lead body opening to a second position distal to the lead body opening. The implantable medical lead may include a probe wire configured to slidably translate through an inner lumen of the dilator.

  • Patent number: 4803029
    Abstract: A process for manufacturing an expandable member such as a tissue expander or like product for use in plastic, reconstructive, and other surgery. A compression mold with a desired initial, predetermined geometrical configuration shape is filled partially with a layer of unvulcanized flexible material, such as silicone, a thin layer of Teflon or like non-stick substance, and followed by another layer of unvulcanized material. The Teflon is "sandwiched" between the unvulcanized material and cured in an oven or by other suitable means. The non-stick material provides a separation region for subsequent expansion by injection of suitable material, air, fluid, etc. The non-stick material can be shaped to provide expansion only in the desired regions. Single, multiple, or overlapped layers of non-stick material may be employed to manufacture a variety of expandable products in the fields of medicine, surgery, consumer and industrial applications.

  • Patent number: 4078347
    Abstract: In a metal building wall construction intended especially for house basement walls, the walls consist of edge interlocked metal panels resting on the web of an upwardly-open perimeter channel that delineates the basement floor. A flange on the channel inner side sets the depth of a poured concrete floor and acts as a screed for levelling the concrete. The perimeter channel web is wider than the panels are thick and they are supported at their inner face by spaced tabs struck up out of the perimeter channel web to leave internal drain holes which permit escape of water received in the perimeter channel. Since the thin passsage between abutting edge webs unavoidably promotes capillary action whereby water can be drawn into it from the adjacent soil, the passage is provided along its length with an enlargement forming a vertical longitudinal drain passage that will trap the water moving into the passage and cause it to travel downwards to the perimeter channel and through the drain holes.
