摘要： An assembly includes an implantable medical device (IMD) including a conductive housing, and a fixation element assembly attached to the IMD. The fixation element assembly includes a set of active fixation tines and an insulator to electrically isolate the set of active fixation tines from the conductive housing of the implantable medical device. The active fixation tines in the set are deployable from a spring-loaded position in which distal ends of the active fixation tines point away from the implantable medical device to a hooked position in which the active fixation tines bend back towards the implantable medical device. The active fixation tines are configured to secure the implantable medical device to a patient tissue when deployed while the distal ends of the active fixation tines are positioned adjacent to the patient tissue.

摘要： A sensor assembly, which may be incorporated by a medical electrical lead, includes an insulative body, formed from a biocompatible plastic, and a sensor mounted on a mounting surface of the insulative body. The mounting surface extends distally from a proximal portion of the insulative body in which first and second conductive inserts extend, being spaced apart and isolated from one another. The sensor is coupled to each of the first and second conductive inserts, and the first conductive insert includes a conductor-coupling end extending proximally from the proximal portion of the insulative body. The sensor assembly may further include an electrode extending around the sensor and the insulative body, wherein the electrode includes an aperture approximately aligned with an active surface of the sensor to expose the active surface. A mounting platform assembly for the sensor assembly may include the conductive inserts and the insulative body.

摘要： An implantable pressure sensor having improved bend error performance is provided having a capsule housing a pressure sensing device, wherein the capsule includes an opening that allows the pressure sensing device to obtain pressure measurements from an environment surrounding the capsule. A rigid bridge is attached to the capsule so as to extend across the opening of the capsule. The bridge includes at least one opening that exposes the pressure sensing device to the surrounding environment. The rigidity of the bridge functions to prevent deformations from bending forces that are exerted on the sensor and also functions to divert loads from such bending forces away from the pressure sensing device to instead travel through the bridge, which in turn resists deformation. A fill material may be situated between the bridge and capsule so as to prevent bodily fluid or tissue from building up in the sensor under the bridge.

摘要： A write element for use in a read/write head having an air bearing surface, so as to reduce pole tip protrusion. The write element includes a pole tip region; an insulation layer formed adjacent to the pole tip region; a coil embedded in the insulation layer which contributes to a protrusion force that generates a pole tip protrusion; and a layer of thermally expansive material formed over the insulation layer, and recessed from the air bearing surface, that expands in response to heat absorption, causing a rotational moment of force that counteracts the protrusion force thus reducing the pole tip protrusion.
