  • Publication number: 20210001117
    Abstract: A monolithic controlled release device (MCRD) for use with an implantable medical device includes a distal face, a proximal face opposite the distal face, and an outer circumferential surface extending between the distal face and the proximal face. A spline-shaped inner lumen extends between the distal face and the proximal face and radially inward from the outer circumferential surface. The MCRD is formed from a mixture including an active pharmaceutical ingredient.

  • Patent number: 10821282
    Abstract: Disclosed herein is an implantable medical device for implantation against cardiac tissue in the administration of electrotherapy to the cardiac tissue. The device includes a distal end and a monolithic controlled release device. The distal end includes a housing structure and a cavity within the housing structure. The cavity opens exterior the implantable medical device via a distal opening. The monolithic controlled release device is within the cavity and proximal the distal opening. The monolithic controlled release device includes a distal face, a proximal face opposite the distal face, an outer circumferential surface extending between the distal face and the proximal face, and a spline-shaped inner lumen extending between the distal face and the proximal face and radially inward from the outer circumferential surface. The monolithic controlled release device further includes an active pharmaceutical ingredient.

  • Publication number: 20190275340
    Abstract: A leadless biostimulator including an attachment feature to facilitate precise manipulation during delivery or retrieval is described. The attachment feature can be monolithically formed from a rigid material, and includes a base, a button, and a stem interconnecting the base to the button. The stem is a single post having a transverse profile extending around a central axis. The transverse profile can be annular and can surround the central axis. The leadless biostimulator includes a battery assembly having a cell can that includes an end boss. A tether recess in the end boss is axially aligned with a face port in the button to receive tethers of a delivery or retrieval system through an inner lumen of the stem. The attachment feature can be mounted on and welded to the cell can at a thickened transition region around the end boss. Other embodiments are also described and claimed.

  • Patent number: 10105536
    Abstract: A leadless pulse generator is disclosed herein. The leadless pulse generator has a body, a helical anchor, an electrode, and a sleeve. The body includes a distal end and a proximal end opposite the distal end. The helical anchor distally extends from the distal end. The electrode is at the distal end. The sleeve distally extends from the distal end and has a proximal face and a distal face opposite the proximal face. The proximal face is adjacent the body. The sleeve coaxially extends about the helical anchor and further has a biased state wherein the distal face is near a distal tip of the helical anchor. The sleeve is configured to compress such that the distal face displaces proximally towards the proximal face upon the distal face being forced against the cardiac tissue in the course of the helical anchor screwing into the cardiac tissue.

  • Publication number: 20120151765
    Abstract: A lead connector end is disclosed herein. The lead connector end may include a generally cylindrical body of unitary construction. The unitary construction may include an electrically non-conductive material extending between three ring contacts imbedded in the electrically non-conductive material. The three ring contacts are offset from each other along a longitudinal length of the unitary body. An electrical conductor extends between two of the three ring contacts and is recessed within an outer circumferential surface of the generally cylindrical body of unitary construction. The electrical conductor is electrically connected to the two of the three ring contacts and forms an integral shunt between the two of the three ring contacts.
