摘要： A transmyocardial implant for establishing a blood flow path through a myocardium between a heart chamber and a lumen of a coronary vasculature residing at an exterior of the myocardium includes a hollow, rigid conduit having a wall defining an outer surface an interior; an open first end; an open second end; a first portion defining the first end; a second portion defining the second end; and a reinforcing wrap. The first portion is dimensioned to be received within the lumen and the second portion is dimensioned to extend from the vasculature to the myocardium into the chamber. The conduit defines a blood flow path way within the interior between the first and second ends. The second portion is formed of a material sufficiently rigid to resist deformation and closure of the pathway in response to contraction of the myocardium. Preferably, the reinforcing wrap extends along at least a section of the outer surface of the wall. In one embodiment, the reinforcing wrap is a spiral winding. In another embodiment, the reinforcing wrap is a woven braid.

摘要： An anastomosis device for securing a biocompatible conduit to a blood vessel. The conduit includes a first end and a second end. A resilient flange is positioned at the second end. The flange is movable between an expanded orientation and a compressed orientation and biased toward the expanded orientation. When the flange is compressed, it is adapted for insertion through an incision in a blood vessel. When the compression is released, the flange returns to its expanded orientation. The first end is adapted to be inserted into and retained within another anatomical structure creating an anastomosis between the blood vessel and the anatomical structure via the conduit. Other anatomical structures specifically include the heart wall of a heart chamber.

摘要： A transmyocardial implant for establishing a blood flow path through a myocardium between a heart chamber and a lumen of a coronary vessel residing at an exterior of said wall includes a hollow conduit having a vessel portion and a myocardial portion. The vessel portion is sized to be received within the lumen. The said myocardial portion is sized to extend from the vessel through the myocardium and into the chamber. The conduit has an open first end and an open second end on respective ones of the vessel and myocardial portions to define a blood flow pathway within an interior of the conduit between the first and second end. At least the myocardial portion of the conduit is formed of a conduit material sufficiently rigid to resist deformation and closure of the pathway in response to contraction of the myocardium. The conduit material is resistant to thrombus formation. An anchor is secured to the conduit and positioned to overlie and be secured to an epicardial surface of the myocardium when the vessel portion of the conduit is secured within the lumen.

摘要： 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.

摘要： A transmyocardial implant includes a hollow rigid conduit having a first portion and a second portion. The first portion is sized to be larger than an initial lumen diameter of a coronary vessel. The first portion is smaller than an enlarged lumen diameter. The second portion is sized to extend from the first portion and through a myocardium into a heart chamber. The implant further includes a stent having a first stent diameter and adapted to be enlarged to an enlarged second stent diameter. In the first stent diameter, the stent is sized to be inserted into the initial lumen diameter. In the second diameter, the stent is sized to dilate the lumen to the enlarged lumen diameter. When the stent is at the second stent diameter, the stent has an internal diameter sized to receive the first portion of the conduit.

摘要： A blood flow path is formed from a heart chamber to a coronary vessel on an exterior surface of a heart wall. A hollow conduit has a vessel portion and a myocardial portion. The vessel portion has an open leading end sized to be inserted into the coronary vessel. The myocardial portion has an open leading end and the myocardium portion is sized to extend through a thickness of the heart wall. The myocardial portion is placed in the heart wall with the open leading end of the myocardial portion protruding into the heart chamber. Blood flow through the conduit from the heart chamber is at least partially blocked. The leading end of the vessel portion is placed in the coronary vessel. Blood flow throug the conduit from the heart chamber and into the vessel is then opened.
