Heart valve prosthesis using different types of living tissue and method of fabricating the same
A heart valve prosthesis and a method of fabricating the same. The heart valve prosthesis uses a leaflet of pig pericardium or a leaflet of cattle pericardium, which has a suitable thickness according to the size of the valve, and a stent. The heart valve prosthesis is fabricated by placing a valve body over a Dacron body, binding the valve body to the Dacron body using stitching fiber, rolling the Dacron body into a cylindrical form such that the valve body is located inside, binding opposite edges of the Dacron body to each other using stitching fiber, and inserting the resultant structure into a stent, which is knitted using a shape memory alloy wire. The heart valve prosthesis is friendly to and is not rejected by human tissue, is free from deformation, and can be implanted using a non-invasive manner without incising the chest wall of a patient.

Device and method for reconstruction of osseous skeletal defects
InactiveUS20050010304A1Promote recoverySuture equipmentsDental implantsSkeletal prosthesisDental implant
A device for the reconstruction of skeletal defects with a flexible member, which is preferably resorbable, attached to a rigid structural prosthesis such as a dental implant, an orthopedic prosthetic implant, or an artificial disc implant. The cavitary space surrounded by the flexible member is filled with osteoconductive and / or inductive materials which eventually matures into bone. The prosthesis is supported by the bed of graft material surrounding it and is gradually unloaded as the bed matures into solid bone. The fixation of the prosthesis into native bone depends on the specific implant and the anatomic area of its use. The flexible member is secured to the margins of the prosthesis using rails, runners, sutures, or other attachment devices that prevent the escape of the bone graft and maintain an initial column of support for the implant.

Selective adherence of stent-graft coverings
InactiveUS20060155369A1Little strengthReduce inflation pressureStentsDomestic articlesMedicineStent grafting
An endoluminal prosthesis including a first polymer member bonded to a second polymer member to selectively encapsulate a stent. Selective bonding between the first and second polymer members results in unbonded regions or pockets that accommodate movement of the stent, permitting compression of the prosthesis using minimal force and enabling collapse of the prosthesis to a low profile. The pockets are believed to encourage enhanced cellular penetration for rapid healing and may contain bioactive substances.
