    摘要: An intravascular stent assembly for implantation in a body lumen, such as a coronary artery, is designed to treat a lesion with vulnerable plaque by reducing the fibrous cap stresses. A polymeric sleeve having first and second ends interconnects a first metallic stent and a second metallic stent. The first end is bonded to a distal end region of the first stent and the second end to a proximal end region of the second stent. The polymeric sleeve can be loaded with a therapeutic drug or agent to further control local thrombosis and/or induce healing if the plaque fibrous cap ruptures during or after implantation. Methods of making an intravascular stent assembly for the treatment of vulnerable plaque are also provided.

    摘要: A stent for implantation in a body lumen for protecting from rupture a fibrous cap in order to treat vulnerable plaque. One embodiment of the stent achieves staged expansion through stronger and weaker circumferential regions, and includes optional anchors positioned at the circumferential transition between the stronger and weaker regions. During the first stage expansion, the weaker region expands moving the anchors laterally apart. The anchors straddle the fibrous cap and embed into the vessel wall. The second stage expansion of the stent exerts gentler stresses by the weaker region against the fibrous cap while the stronger region exerts greater stresses on the remainder of the vessel wall to open the vessel.

    摘要: A medical device for treating a defective heart valve. The medical device comprises a distal anchoring member for disposing in a blood vessel. A proximal anchoring member for disposing in or at an entrance of the blood vessel. A telescoping assembly coupling at a first end to the distal anchoring member and at a second end to the proximal anchoring member. The telescoping assembly is deployable into the blood vessel. The telescoping assembly reduces a distance between the distal anchoring member and the proximal anchoring member, wherein the telescoping assembly comprises of at least two members capable of sliding into each other giving the telescoping assembly adjustable lengths.

    摘要: A knotless suture anchor provides a method for securing soft tissue to a rigid structure such as bone. The anchor has an inner member that receives suture thread and rotates within an outer tubular member. As the inner member rotates, the suture thread is wrapped onto the inner member thereby increasing contact with the outer tubular member which applies pressure to the wrapped suture thread to retain it in position on the inner member while simultaneously and adjustably tensioning the suture thread. A ratchet prevents undesirable counter-rotation, although the ratchet can be released to permit loosening of the suture thread. Also described is a suture bridge and suture platform for providing further stabilization of a tendon. A method for repairing rotator cuff tears is also described.
