Wire rope assembly unit
A wire rope assembly unit including a wire rope and a device for assembling the wire rope. The device is fastened at one end of the wire rope and has a connecting element arranged at the front on the end of the wire rope. The assembly unit has a sleeve that engages around an outer surface of an end section of the wire rope. The sleeve is made of a material of lesser rigidity than strands of the wire rope and, optionally, than the connecting element. The sleeve is pressed, hammered and/or rolled onto the wire rope and, optionally, onto the connecting element to produce a form-locked connection. Outer strands of the wire rope are separated from the wire rope in a rope section, in which the wire rope is arranged inside the sleeve, and the sleeve is connected to ends of the outer strands at its one edge.
TOOL AND METHOD FOR COMPRESSING A STENTED PROSTHESIS
A tool for compressing a stented prosthesis. The tool includes first and second sets of rollers. The first set includes a plurality of rollers arranged to define a first working region having a first working diameter. The second set includes a plurality of rollers arranged to define a second working region having a second working diameter. The sets of rollers are arranged such that the working regions are axially aligned. The first working diameter is greater than the second working diameter. A stented prosthesis traversing the first working region and then the second working region is forced to a compressed state. In some embodiments, the tool includes one or more intermediate sets of rollers between the first and second sets of rollers, with each of the intermediate sets of rollers defining a working region having a working diameter. The respective working diameters progressively decrease in a downstream direction.
Methods for improving stent retention on a balloon catheter
A method of crimping a stent on a balloon of a catheter assembly is provided. A polymeric stent is disposed over a balloon in an inflated configuration. The stent is crimped over the inflated balloon to a reduced crimped configuration so that the stent is secured onto the balloon. The balloon wall membrane is wedged or pinched between the strut elements of the stent for increasing the retention of the stent on the balloon.
System, method and apparatus for preserving and capping tubes
A system for preserving and capping tubes includes a compressed air reservoir for storing compressed air, a preservative reservoir containing a supply of a preservative, a nozzle in fluid communication with the compressed air reservoir and the preservative reservoir for injecting the preservative into the interior of a tube, and a capping device configured to insert a cap onto the end of the tube.
Devices and methods for crimping a medical device
Devices, systems, and methods for crimping a medical device are disclosed. More specifically, the present disclosure relates to devices, systems, and methods for reducing the diameter of a collapsible heart valve prosthesis to be loaded onto a delivery device. The devices, systems, and methods using at least one funnel to crimp the heart valve prosthesis and load it onto the delivery system.

GUIDE CAP AND LOADING SYSTEM FOR LOADING IMPLANT INTO DELIVERY SYSTEM
A guide cap and a loading system for loading an implant into a delivery system are disclosed which are capable of simplifying operations required in interventional surgery using the implant. The guide cap has a lumen passing therethrough and includes: a conical section; a straight or conical tube in communication with a small open end of the conical section; and a flange, wherein a large open end of the conical section flares outward and thereby forms the flange. The loading system includes a guider and the guide cap. During the process of loading the implant into the delivery system, the guide cap enables the valve prosthesis to be coupled to the connector of the delivery system and allows the valve prosthesis to be compressed so as to be entirely capsuled in the delivery system with relatively easy and quick operations, thereby reducing surgery time during its clinical use.
COMPRESSION TOOL WITH REVERSIBLE BLOCK
A compression tool for fastening a cable to a connector comprising an elongated tool frame, an anvil secured to one end of the tool frame, a compression plunger slidable along a portion of the tool frame, a handle set adapted to move the compression plunger toward and away from the anvil and a spacer block for securing the connector a distance from the anvil. The handle set may include a first handle movable from a first position wherein the plunger is a first distance from the anvil to a second position wherein the plunger is a second distance from the anvil. The spacer block may include a first end and a second end having a different depth from the first end and be rotatable so that the first end when rotated to the active position secures the connector a first distance from the anvil and the second end, when rotated to the active position secures the connector a second distance from the anvil.
