Abstract: An implantable medical lead may include an electrode at a distal portion of the lead that is configured to monitor or provide therapy to a target site. The lead may include a visible indicator that is visible to the naked eye of a clinician at a medial portion of the lead that is configured to indicate when the electrodes of the lead are longitudinally and radially aligned properly to monitor or treat the target site. A clinician may insert the lead into the patient using an introducer sheath inserted to a predetermined depth into the patient and subsequently aligning the distal portion of the lead by orienting the indicator at an entry port of the introducer sheath.

Abstract: An apparatus can include a display, a facial interface, and a connector between the display and the facial interface. The facial interface can at least translate or rotate relative to the display via the connector.

Abstract: A cryogenic coupling device includes a valved receptacle and a valved nozzle. Rollers in an outer collar of the receptacle are received in helical channels along a collar of the nozzle. A notch or detent in each of the channels provides a vent position to vent fluid before the nozzle is fully disconnected from the receptacle. Interface seals on the nozzle include first and second annular seals that function as ice and containment scrapers, as well as fluid seals. The nozzle has a rotatable handle assembly, isolated from the fluid path, which provides easy connect and disconnect of the nozzle from the receptacle. The handle assembly includes a thermal break, and is easily removable from the nozzle, along with other parts of the nozzle and receptacle, for service and maintenance.

Abstract: A push-to-connect type coupler has an intermediate venting position for the nipple. The coupler includes a coupler socket having an inner sleeve, an intermediate coupler body, and an outer sleeve formed from tubular or cylindrical components which are axially movable with respect to one another. A valve member is disposed axially within the coupler and is normally biased into a closed position. The inner sleeve of the coupler is spring-biased toward the opening of the coupler, and includes an inner set of captive coupling balls. The coupler body also has an outer set of captive coupling balls, and a locking mechanism is disposed between the coupler body and the outer sleeve. When the nipple is inserted into the coupler, the nipple is retained by the interaction of the outer set of coupling balls with a deep groove in the inner sleeve, and the inner set of coupling balls with a channel formed in the nipple.

Abstract: Several forms of releasable magnet door latches are disclosed. In one embodiment, a pull on a knob mounted in a housing attached to a door is translated by an inclined cam surface into rotary motion of an actuator rod extending into the door. The rod mounts a horseshoe magnet which is rotated with rotation of the rod. An intermediate member is mounted on the opposite surface of the door and contains a pair of ferromagnetic pole pieces which are spaced from each other and which act as extension of the poles of the horseshoe magnet in the ON position of the magnet. In such position, the magnet attracts a ferromagnetic plate mounted on the door frame. The intermediate member also contains a transverse shunt piece which bridges the poles of the magnet when the magnet has been rotated through an arc of 90.degree. to an OFF position. In the other embodiments, a rectangular permanent magnet having poles formed on opposite side surfaces has a pair of pole plates disposed on such side surfaces.
