Appl. No.:

10/054672

Assignee:

International Classification:

A61B005/0215

US Classification:

600488, 600486, 600587, 607 60

Abstract:

The progress of a endovascular cardiac repair can be monitored by inserting a pressure transducer sensor using a catheter into a chamber of the heart during endovascular repair and then using a small, hand-held read out device to measure pressure easily, safely, inexpensively and accurately. In one aspect a sensor is introduced into the body by the steps of folding or rolling the sensor into a cylinder, loading it into a catheter, and deploying into the heart chamber by allowing it to unroll or unfold, either by itself or facilitated by the incorporation of a super-elastic alloy component.

International Classification:

A61F 2/06
F16C 11/00

US Classification:

623 115, 403103

Abstract:

A stent is constructed using interconnected links having micro-mechanical latching mechanisms. The micro-mechanical latching elements allow relative rotational movement of interconnected links in one rotational direction but restrict relative rotational movement of the two links in the opposite direction. The micro-mechanical latch surface features are formed using microelectronic mechanical systems (MEMS) manufacturing methods. The male surface of the latching components contains an array of ridges or protrusions, and the receiving surface contains a matching array of recesses. The array of ridges or protrusions and the corresponding recesses have uniformly dissimilar slopes that result in a substantially greater frictional force in one direction than in the opposite direction. The separation distance between the two surfaces is such that the male latch surface is engaged with the receiving surface recesses in the low stress “locked” state, preventing motion in the undesired direction. Each male ridge or protrusion can be underlined by a void that promotes elastic deflection when sliding in the desired direction and recovery into the ‘locked’ state when aligned with the recesses.

International Classification:

A61B 5/00

US Classification:

600549

Abstract:

A sensor for wirelessly determining a physical property within a defined space comprises an electrical resonance and has a high quality factor Q. The quality factor Q is sufficiently high that a signal generated by the sensor can be received outside the defined space. The sensor may optimally have a dielectric coating.

Abstract:

A stent constructed using elements containing micro-mechanical latching mechanisms is disclosed. The micro-mechanical latching elements allow sliding motion between two surfaces in one direction, and restrict sliding motion in the opposite direction. The micro-mechanical latch surface features are formed using microelectronic mechanical systems (MEMS) manufacturing methods. The male surface of the latching components contains an array of ridges or protrusions, and the receiving surface contains a matching array of recesses. The array of ridges or protrusions and the corresponding recesses have uniformly dissimilar slopes that result in a substantially greater frictional force in one direction than in the opposite direction. The separation distance between the two surfaces is such that the male latch surface is engaged with the receiving surface recesses in the low stress “locked” state, preventing motion in the undesired direction.

International Classification:

H01F 7/06

US Classification:

29606, 29600, 29604, 29605

Abstract:

In the disclosed method of manufacturing an implantable wireless sensor, a cavity is etched in one side of a first substrate. A conductive structure are formed on the base of the cavity. A second conductive structureare formed on a surface of a second substrate, and the two substrates are mutually imposed such that the two conductive plates and coils are disposed in opposed, spaced-apart relation. A laser is then used to cut away perimeter portions of the imposed substrates and simultaneously to heat bond the two substrates together such that the cavity in the first substrate is hermetically sealed.
