    摘要： A system for locally stabilizing an anastomotic site of a vessel of a beating heart during a surgical procedure is disclosed. The system includes bonding a pad to the myocardium and attaching a control arm to the pad, all by use of a bioabsorbable adhesive. The control arm is grasped and manipulated by a retractor thereby stabilizing the anastomotic area during the surgical procedure. The pad is optional and can be ommitted in one embodiment where the control arm has feet that are directly bonded to tissue. The pad may also have barbs or can include suction cups. The pad can include a helix-shaped fastener or a mechanical fastener that can be easily linked or hooked to a surgical instrument for manipulation.

    摘要： The present invention is directed to a balloon catheter, such as a dilatation catheter and a stent delivery catheter with improved stiffness transition and specifically with no sudden changes in stiffness along the catheter length. The balloon catheters of the present invention may be used alone or be mounted with a stent in. The balloon catheters of the present invention may be used in peripheral, coronary, or neurovascular applications. The present catheter has more than one portion with different bending stiffness values, each portion comprising of components that gradually transition the bending stiffness of that portion to an adjacent portion, thus reducing the differential in bending stiffness in moving from one region to another, when the catheter is used alone or in combination with a stent in a stent delivery system.

    摘要： An intra-luminal device comprises a flow retainer and/or modulator for maintaining an embolic mass within an aneurysm and, optionally, for diverting or modulating fluid flow, and an anchoring element for fixating the retainer within a lumen in a patient's body. The retainer is introduced into the body lumen and positioned with the retainer across the entrance to a body cavity or a body lumen with an embolic mass disposed within to prevent the embolic mass from migrating into the patient's vasculature. The retainer may also be a diverter or modulator used to divert or modulate the luminal fluid flow to the entrance to the body cavity or lumen. The anchoring element, which may be attached to the retainer, is deployed to permanently secure the retainer within the body lumen in the desired position.

    摘要： A vascular catheter includes a blade tip at its distal end. In the specific embodiments, a blade is mounted within the blade tip and a mechanism provided for extending the blade transversely when the blade tip is located within a region of stenosis. By extending the blade and axially translating the catheter so that the blade forms an incision within the region of stenosis, improved angioplastic treatment can be achieved.
