Estimating the term…
A catheter assembly (1), an implant system, an implant delivery system and a method of use thereof. In the implant delivery system, an inner tube (120) is made of an elastic material, and an outer sheath tube (110) and a guidewire tube (130) are each made of a plastic material. A distal end portion of each of the outer sheath tube (110) and the guidewire tube (130) is shaped into a curved form to provide a curved channel for the inner tube (120). The inner tube (120) is elastically inserted through the curved channel. This dispenses with the need for bending control from an outer sheath tube control device (21) and an inner tube control device (22), reducing requirements and difficulties in designing them and thus resulting in cost savings. Moreover, it makes the implant delivery system more easily operable, safer and more reliable, with lower requirements on a surgical incision, and capable of delivering a stent through a curved access accurately to a designated site.
A catheter assembly, comprising an outer sheath tube, an inner tube and a guidewire tube that are sequentially sleeved one over another from outside inwards, wherein:
An implant system, comprising a catheter assembly, a delivery handle, a tapered head and a retaining head, wherein the retaining head and the tapered head are sequentially disposed from proximal to distal at a distal end of an inner tube, wherein an implant is crimped within the inner tube and is at least mostly confined between the tapered and retaining heads,
