摘要： A blade for a cutting instrument includes a handle, a body, and at least three cutting edges along the body. The body has first and second sides extending along a longitudinal center axis. The body has a proximal end at the handle and a distal tip remote from the handle. The at least three cutting edges are oriented at corresponding angles with respect to the longitudinal center axis and are asymmetrically distributed with respect to the longitudinal center axis.

摘要： An implant delivery instrument includes a housing with a main body section that defines a passage therethrough from a front end of the main body section to a back end of the main body section. The passage receives an obturator through an opening at the back end, and also receives an implant device. Movement of the obturator through the passage pushes the implant device through a discharge opening at the front end and through an incision into a subdermal pocket of a patient. The housing includes a tab connected to and projecting from the front end of the main body section. The tab has a blunt dissection tip for maintaining the incision in an open state without creating or enlarging the incision, and the tab is configured to surround the implant device moving through the discharge opening along only one side of the implant device.

摘要： 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.

摘要： Shocking electrodes for implantable medical devices may include a coiled conductor that has an oblong cross-sectional shape and is configured to deliver high-voltage shocks for defibrillation therapy. The coiled conductor includes an electrically conductive element that is helically wrapped and defines the oblong cross-sectional shape. The electrically conductive element is one of (i) a multi-filar ribbon wire that includes multiple strands disposed side-by-side along a length of the multi-filar ribbon wire, (ii) a micro-coil that includes a coiled strand, or (iii) a micro-cable that includes multiple interwoven strands along a length of the micro-cable.

摘要： A pulse generator comprises a header connector assembly coupled with a housing. The header connector assembly includes a connector assembly and a header enclosing the connector assembly. The connector assembly includes an electrically insulative segment, a first electrically conductive segment, and a second electrically conductive segment axially spaced apart from the first electrically conductive segment by the electrically insulative segment. Each electrically conductive segment includes a connector ring, a spring housing and a spring supported by the spring housing. The connector ring and spring housing are in electrical communication with each other. The electrically insulative segment includes an insulator ring that is positioned between the first and second electrically conductive segments. The insulator ring includes a first end and a second end axially opposite the first end. The first end includes a first recess that opens axially and receives therein a portion of the first electrically conductive segment.

摘要： A lead for an implantable medical device (IMD) includes an electrode having a plurality of brick segments that are discrete and mechanically connected to one another in a line. The brick segments are electrically conductive and electrically connected to one another. The brick segments are configured to be powered by a pulse generator of the IMD to deliver high-voltage shocks for defibrillation therapy.

摘要： A therapy lead has a distal header, a helix-shaft assembly, and a ring seal. The distal header has a cylindrical passage, and the helix-shaft assembly has a shaft and a helical anchor distally extending from the shaft. The shaft extends through the cylindrical passage. The ring seal circumferentially extends about the shaft and inside the cylindrical passage. The ring seal has a proximal face, a distal face, an outer circumferential surface, an inner circumferential surface, and a side wall. The distal face is opposite the proximal face. The outer circumferential surface extends between the proximal face and distal face. The inner circumferential surface is opposite the outer circumferential surface and extends between the proximal face and distal face. The inner circumferential surface defines a center hole of the ring seal that extends between the proximal face and distal face. A side wall extends in a continuous ring about the center hole and is defined by the proximal face, the distal face, the outer circumferential surface, and the inner circumferential surface. The side wall includes a radial cross section that is at least generally chevron-shaped.
