“…6,17,18 Patients were eligible for the trial if they had New York Heart Association class II to IV heart failure, were aged 18 to 80 years, and had LV ejection fraction (EF) Ͻ45%, LV end-diastolic dimension Ͼ6 cm, and 6-minute walk distance Ͻ450 m. Patients were enrolled into the mitral valve surgery stratum (nϭ193) if they required mitral valve surgery because of severe MR (grade Ն3ϩ). They were randomly assigned to mitral valve surgery plus CSD or mitral valve surgery alone.…”

“…CorCap CSD implant techniques have been described previously. 18 The key of implantation was to obtain a conformal fit with the CSD evenly distributed around the heart without any folds and with an even "tent" test in which the CSD is lifted off the heart with a forceps and then returns to a smooth fit within 1 to 2 heartbeats. Care was taken to make sure that the LV end-diastolic dimension was not reduced by Ͼ10% compared with baseline.…”

“…The authors also concluded that the wrap material did not promote any significant limitation on ventricular filling. Available evidence generally agrees with this assertion [28][29][30]. In more recent times, the CorCap TM CSD, a polyester passive constraining device (CorCap TM Cardiac Support Device, Acorn Cardiovascular, Inc.) has been evaluated as a treatment for heart failure in animal and clinical studies.…”

The Laplace equation points to the importance of ventricular wall stress as a factor in heart failure development and progression. Based on animal and clinical experience with active and passive cardiomyoplasty, a synthetic passive constraint was proposed as a means of reducing excessive wall stress, and thus assuaging disease progression. The Acorn CorCap CSD Cardiac Support Device was designed to provide passive diastolic support and serve as a constraint against chronic cardiac dilation in heart failure. Basic and uncomplicated in appearance, the device nevertheless incorporates numerous sophisticated structural and functional features intended maximize therapeutic value. The device is fabricated from medical grade multifilament polyester yarn, in a specific knit construction chosen to provide structural integrity, low physical profile, pliability for intimate contact with the epicardial surface, ease of manipulation during implantation, and anisotropic compliance characteristics to encourage beneficial reverse remodeling.

“…[29,30] Atlas stitch is the basic structure and the material is multi-filamentous yarn to provide high-strength and fatigueresistant characteristics, while maintaining flexibility. [31] The fabric with warp-knitted atlas stitch is glossy and it is easy to slide on the surface of heart to provide acute wall support.…”

There are many kinds of medical textiles, such as woven textiles, non-woven textiles, braided textiles and knitted textiles. Non-woven medical textiles constitute more than 60% of the total medical textiles used, but are almost disposable ordinary medical textiles. While knitted fabrics forms a small part of the medical textiles, but are greatly applied in high-tech medical textiles, containing artificial blood vessels, hernia patches, cardiac support devices, knitted medical expandable metallic stents and tendon scaffolds. Knitting structures, including weft knitting structure and warp knitting structure. The knitted textiles are popular for their loose structure, greater flexibility, higher porosity, more flexible structure and better forming technology. The present article will introduce some knitting structures and materials applied in the medical textiles in accordance with non-implantable, implantable, extra-corporeal textiles and healthcare and hygiene products.
