Implants and associated delivery systems for promoting angiogenesis in ischemic tissue are provided. The implants may be delivered percutaneously, thoracically or surgically and are particularly well suited for implantation into the myocardium of the heart. The implants are configured to have a first configuration having a low profile and an expanded, second configuration having a large profile. The implants are delivered to the ischemic tissue location in the first configuration, implanted then expanded to the second configuration. The expanded implants maintain a stress on the surrounding tissue, irritating and slightly injuring the tissue to provoke an injury response that results in angiogenesis. The flow of blood from the surrounding tissue into the implant and pooling of the blood in and around the implant leads to thrombosis and fibrin growth. This healing process leads to angiogenesis in the tissue surrounding the implant. Additionally, the implants may contain an angiogenic substance or a thrombus of blood, preloaded or injected after implantation to aid in initiating angiogenesis.

This endpiece includes at least one end segment of each armor element, an end vault and a cover, the end vault and the cover delimiting between them a chamber for receiving the end segment and a material for filling the receiving chamber, in which the end segment is embedded. The endpiece includes a spacing member positioned so as to internally bear upon the end segments of the armor elements of at least one armor layer. This spacing member defining, on at least one end segment of a armor element of said armor layer, contact areas axially spaced apart along said end segment, the contact areas delimiting between intermediate contact spaces between the filling material and the end segment.

Absorbable stents and absorbable stent coatings have been developed with improved properties. These devices preferably comprise biocompatible copolymers or homopolymers of 4-hydroxybutyrate, and optionally poly-L-lactic acid and other absorbable polymers and additives. Compositions of these materials can be used to make absorbable stents that provide advantageous radial strengths, resistance to recoil and creep, can be plastically expanded on a balloon catheter, and can be deployed rapidly in vivo. Stent coatings derived from these materials provide biocompatible, uniform coatings that are ductile, and can be expanded without the coating cracking and / or delarmnating and can be used as a coating matrix for drug incorporation.

The invention provides a collarless round-collarband sewing process of an elastic fabric. The process comprises the following steps: cutting out round-collarband garment parts of the elastic fabric, wherein before sewing, a straight-silk lining bar with the width being 1cm is sewn to the back side of the neckline part in an adhesion manner, so that the problem that the collarband part is subjected to oblique-silk cutting, therefore, the size of the neckline can become large easily after sewing is solved; sewing the cut-out garment parts of the elastic fabric and the lining, wherein after sewing, the length difference between the contour line and the sewing line needs to be reduced; sewing an invisible line at the position, 0.1cm-0.2cm away from the sewing line, of the sewing edge, wherein when the invisible line of the collarband is sewn, an oblique-silk lining bar with the width being about 1.2cm is additionally sewn under the back side of the lining, and the side, with colloidal particles, of the oblique-silk lining bar is opposite to the back side of the lining; carrying out reverse ironing on the collarband, so that the oblique-silk lining bar is ironed to the elastic fabric in an adhesion manner, therefore, the sewing edge is fixed to the elastic fabric, further, the hardness of the elastic fabric is enhanced, finally, the support force is increased, and the problem that the sewing edge upwarps, consequently, the collarband turns outwards is solved.

A zoom lens system includes, in order from an object side to an image side, a first positive lens group (G1), a second negative lens group (G2), a third positive lens group (G3), and a fourth positive lens group (G4). The second and third lens groups are movable for varying the focal length. The zoom lens system offers a four-times zoom ratio, and employs two plastic aspheric lenses (L3, L9) and a resin hybrid lens (L6). The first lens group consists of two lenses (L1, L2) arranged in an abutting relationship. The second and third lens groups each includes a pair of cemented lenses (L4, L5; L7, L8).
