A method and a wearable apparatus for disease diagnosis are provided. The method is applied to the wearable apparatus with an image capturing unit and a display unit. In this method, a plurality of input images in a field of view of the wearable apparatus are captured by using the image capturing unit, wherein each of the input images contains an array of pixels. The variations of the pixel values in a time domain are analyzed. The pixel variations within a specific frequency range are magnified and the magnified pixel variations are added onto the original ones to generate an output image. The output image is overlapped with a current image in the field of view of the wearable apparatus and displayed on the display unit.

Method and wearable apparatus for disease diagnosis

A bioabsorbable polymeric stent with time dependent structure and properties and methods of treating a diseased blood vessel with the bioabsorable polymeric stent are disclosed. The structure and properties of the stent change with time and allow the vessel to be restored to a natural unstented state. The bioabsorbable stent loses mechanical integrity in a controlled manner due to modification of selected structural elements.

Method of treatment with a bioabsorbable stent with time dependent structure and properties and regio-selective degradation

An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The stent includes a plurality of rings connected by links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The stent can be compressed or crimped onto a catheter to a very low profile since links are integrally formed from a portion of the struts forming the rings. The stent is constructed so that the cylindrical rings are very close together in order to provide maximum scaffolding, and if the stent has a drug coating, to provide a uniform drug delivery over the length of the stent. The connecting links are integrally formed from a portion of the struts forming the rings so that the links can have a maximum length thereby providing increased longitudinal flexibility of the stent.

Intravascular stent with integrated link and ring strut

System including a delivery catheter and a stent disposed at a distal end of the delivery catheter. The stent includes a plurality of radially expandable rings disposed adjacent to one another to define a tubular member having a proximal end portion, and a distal end portion, and a middle portion, each of the radially expandable rings including a plurality of strut members. The middle portion of the tubular member include a plurality of interconnection members extending between longitudinally adjacent expandable rings, the number of the plurality of the interconnection members being greater than that of the end portion of the tubular member. The stent also includes a transition section between the end portion and the middle portion, the transition section including at least one open cell and at least one closed cell. The stent can be self-expandable or balloon expandable.

Stent designs for use in peripheral vessels

Stent designs for use in peripheral vessels, such as the carotid arteries, are disclosed. The stents consist of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting members placed so that the stent is flexible in a longitudinal direction. The cylindrical elements are generally serpentine wave pattern transverse to the longitudinal axis between alternating valley portion and peak portions, the valley portion including alternating double-curved portions and U-shaped portions. The interconnecting members are attached to the double-curved portions to connect a cylindrical element to an adjacent cylindrical element and interconnecting members are attached to the U-shaped portions to connect the cylindrical element to the other adjacent cylindrical element. The designs include an eight crown and six crown stent which exhibit flexibility and sufficient radial strength to support the vessel.
