With this bill, the retreat possible catheter whose it is desirable to use for in plant delivery catheter system, is disclosed. The catheter is produced relatively with the material of flexibiility at least in the distal (2036) part the long tubular sheath (16), relatively with the non expansion characteristic material to be produced, in order the additional strengthening which is installed relatively in the sheath of the material of flexibiility, the sheath (16) according to at least the portion of length (20), and the sheath (16) and additional strengthening (20) the tensile element which transmits pulling power to longitudinal direction (18) to have, the tensile element (18), pulling power additional strengthening (20) to transmit directly, the additional strengthening which is exposed relatively from the material of flexibiility (20) it features that it is directly connected to part. With this bill, also in plant delivery system and its production method of having the retreat possible catheter such as that are disclosed.< Selective figure >Figure 5b本明細書では、インプラント送達カテーテルシステムに使用するのが好ましい引き込み可能カテーテルが開示される。カテーテルは、少なくとも遠位部分において比較的可撓性の材料で作製される細長い管状シース(16)、比較的非伸長性の材料で作製され、比較的可撓性の材料のシースに、シース(16)の長さの少なくとも一部に沿って組み込まれる補強構造(20)、ならびにシース(16)および補強構造(20)に長手方向に引張力を伝達する引張要素(18)を備え、引張要素(18)が、引張力を補強構造(20)に直接伝達するように、比較的可撓性の材料から露出される補強構造(20)の一部に直接接続されることを特徴とする。本明細書では、そうした引き込み可能カテーテルを備えるインプラント送達システムおよびその製造方法も開示される。【選択図】図5b
