The twisting device drives a two-finger chuck coaxial with a big gear to clamp the guide suture catheter to rotate, and the two-finger chuck clamps the guide suture catheter by opening and closing. The guide suture guide device drives a cam to adjust distance of guide wheels to adapt to the diameter of the guide suture catheter. The suture pressing device is controlled by an electromagnet, two moving fingers are closed when being electrified to clamp and fix the position of a guide suture. When power is cut off, the moving fingers are separated, and theguide suture can move freely. The bedside positioning device comprises an X-axis moving device and a Y-axis moving device, and the X-axis moving device drives the Y-axis moving device to move linearly through a ball screw. The Y-axis moving device drives the vascular interventional surgical robot to move and position through the ball screw.

An implantable annuloplasty suture guide is intended to lie against at least a portion of an annulus surrounding a human heart. The implantable annuloplasty suture guide is made of an elongated ribbon of braided, heat setable material. The braided, heat-setable material is heat-set in a curved lengthwise configuration corresponding to at least a portion of the annulus of the human heart valve. A method of making an implantable annuloplasty suture guide configured to lie against at least a portion of an annulus defined by tissue surrounding a human heart. The method includes the steps of providing an elongate biocompatible ribbon comprising a braided, heat setable material. A fixture is provided, with the fixture comprising a heat conducting material defining an elongate cavity having a curved length-wise configuration corresponding to at least a portion of the annulus defined by the tissue surrounding the human heart. The elongate biocompatible ribbon is placed in the cavity and the fixture is heated to provide a select temperature for a select time in the cavity, the select temperature and the select time being sufficient to heat-set the elongate biocompatible ribbon in the curved length-wise configuration.

A system for piercing through biological tissue and providing access to internal structures; particularly, intra-abdominal structures, and closing an opening in the tissue. The system includes a suture guide sub-system having a tissue positioning sub-system for engaging segments of tissue disposed proximate the tissue opening and a suture passer sub-system that slideably engages the suture guide sub-system. The suture passer sub-system includes suture deployment and capture means that is configured to removably secure a suture thereto and deliver the suture to the segments of tissue disposed proximate the tissue opening.
