Abstract
An insertion tool facilitates insertion of a vessel end of a transmyocardial implant into a coronary vessel. The insertion tool has a hollow sheath and mating dilator. The sheath has an external dimension sized for the sheath to be received within a lumen of an expanded size of the coronary vessel. A tapered portion extends from the dilator coaxially with an axis of the sheath. The tapered portion narrows from a cylindrical body portion to a leading tip of the tapered portion. The leading tip of the tapered portion is sized to be received within the lumen of a constricted size of the coronary vessel. The tapered portion and body portion are retractable from the sheath. After such retraction, the leading end of the implant is placed within the sheath. The sheath is split at a part-line such that the sheath can be pulled rearwardly from the vessel without disrupting the coronary vessel following placement of the implant within the sheath.
