Introducer device |
摘要 |
An introducer and method provides a surgical tool with a pathway through tissue to a surgical site, wherein the surgical tool includes at least one surgical instrument. The introducer comprises a flexible sheath having a distal portion including a distal end and is arranged for receiving the surgical tool. A tissue separation tip at the distal portion of the sheath advances the sheath into the tissue towards the surgical site. The tissue separation tip is arranged to form a tissue gap and provide the at least one surgical instrument access to the tissue gap for performing a medical procedure consonant with the formation of the tissue gap or the performance of work at the surgical site. |
