The present disclosure describes numerous example medical instruments that include an elongated portion having a proximal end and a distal end, and a passage defined therethrough and a soft tip coupled to the distal end of the elongated portion. The tip may be formed from a soft material. In some instances, the soft material may have a hardness less than the material forming the elongated portion. The tip may also include a passage that may be of a substantially equivalent size as the passage of the elongated portion. The tip may be coupled to the distal end of the elongated portion at an engagement site having a surface area greater than a cross-sectional area of the elongated portion.本揭露描述眾多例示醫療器材，其包含一具有一近端及一遠端之長條部分，以及一被定義穿過該長條部分的通道及一軟端部，該軟端係耦合至該長條部分之遠端。該端部可被形成自一軟材料。在一些情況下，該軟材料可具有一低於形成該長條部分的材料的硬度。該端部也可包含一通道其可與該長條部分的通道具有實質上同等的尺寸。該端部可於一囓合部位被耦合至該長條部分之遠端，該囓合部位具有一比該長條部分之截面積更大的表面積。
