Abstract: A method for patterning a surface includes providing a first layer of mechanically deformable material having a first surface. A second layer of mechanically deformable material is placed on the first surface. At least a portion of the second layer is controllably displaced to form at least one patterned void through the second layer.

Abstract: A cardiac pressure monitoring device includes a fixation member defining a central opening to facilitate slidably positioning the fixation device about a pacemaker lead wire. At least one sensor is coupled to the fixation member. The at least one sensor is configured to sense a physical, chemical, and/or physiological parameter within a cardiac chamber.

Abstract: A method for monitoring a right atrial pressure (RAP) and a left atrial pressure (LAP) for diagnosis of a heart condition includes positioning a transseptal device with respect to a pulmonary artery to monitor at least one flow characteristic of blood through the pulmonary artery. The transseptal device is configured to generate one or more signals representative of the at least one flow characteristic. A right ventricular end diastolic pressure (RVEDP) and a left ventricular end diastolic pressure (LVEDP) are detected to facilitate monitoring the heart condition.

Abstract: A radio frequency identification (RFID) tag device for monitoring at least one of ingestion and digestion by a subject of a solid dosage form includes a substrate attachable to the solid dosage form or at least partially embedded into the surface of the solid dosage form and an RFID tag at least partially formed on the substrate. The RFID tag is configured to generate a signal and transmit the generated signal to an external receiver to facilitate monitoring at least one of ingestion and digestion by the subject of the solid dosage form.

Abstract: A method for fabricating a wireless pressure sensor includes providing a first substrate. A portion of the first substrate is controllably displaced to form a cavity. A conducting material is patterned on the first substrate to form a first capacitor plate and a first inductor. A second substrate is provided. A conducting material is patterned on the second substrate to form a second capacitor plate. The second substrate is attached to the first substrate to seal the cavity such that at least a portion of the second substrate is movable with respect to the first substrate within the cavity in response to a change in an external condition. A hermetically sealed capacitive pressure sensor may reside in the cavity between the first substrate and second substrate.

Abstract: A method for fabricating an endovascular implant includes providing a mold having a controlled topography. A wire is positioned about at least a portion of the mold. A polymeric material coating is applied to cover at least a portion of the mold. The wire and the polymeric material coating are released from the mold, wherein the polymeric material coating has a controlled topography at least partially replicating the controlled topography of the mold.

Abstract: An implantable medical device including a tubular housing defining a passage between a proximal end and a distal end of the housing. The passage providing fluid communication through the housing. A sensing unit is positioned within the passage and coupled to the housing. The sensing unit is configured to sense at least one of a physical, chemical, and physiological parameter within the passage.

Abstract: An implantable medical device includes a first sensor array movable between a collapsed configuration and a deployed configuration. The first sensor array includes a first main portion and at least one rigid sensor movably coupled to the first main portion. A coupler is operatively coupled to the first sensor array and configured to couple the implantable medical device with respect to a heart chamber.
