Abstract: In an illustrative embodiment, a connector for interfacing a flexible circuitry device with an apparatus includes a housing having a lower housing portion and an upper housing portion with a button region for a button, circuit board(s) including contact(s) for interfacing with corresponding contact(s) of an I/O section of flexible circuitry, retention feature(s) for frictionally retaining the I/O section against the contact(s) of the circuit board(s), and a cable interface. When the button is in a retain position, the button creates a downward force on the retention feature(s) toward the lower housing portion, thereby frictionally retaining the I/O section of the flexible circuitry, and, when the button is in a release position, the retention feature(s) is displaced in a direction of the upper housing portion, thereby creating or widening an aperture for insertion of the I/O section.

Abstract: An anchor sleeve for securing a therapy delivery element, such as a stimulation lead or catheter, within a living body, that includes an inner sleeve with pre-formed locations of weakness that facilitate localized deformation. The anchor includes a deformable outer sleeve with a primary lumen extending along an axis. The outer surface of the outer sleeve includes a plurality of suture grooves oriented generally concentric to the axis. The inner sleeve includes a plurality of beams connected at deflection regions arranged around a secondary lumen. The inner sleeve is located in the primary lumen adjacent to the suture grooves so that the secondary lumen is generally concentric with the primary lumen. A plurality of locations of weakness are preformed in each of the beams to facilitate localized deformation in response to a radially inward force applied around the suture grooves by a suture material.

Abstract: An epidural needle for implanting therapy delivery elements in an epidural space. The epidural needle includes at least an outer cannula containing an inner cannula, and a stylet located within the lumen of the inner cannula. The inner cannula substantially extends across the elongated opening at the distal end of the outer cannula to form a seal with the ligament during “loss of resistance” testing. Loss of resistance testing is performed by removing the stylet from the inner cannula. Once the epidural needle is positioned in the epidural space, the inner cannula is removed to facilitate implantation of a therapy delivery element in the epidural space.
