Angled vascular anastomosis system

An integral anastomosis connector system, comprising:

• a fitting comprising a base adapted for attachment to a graft, a leading segment adapted for introduction into a host vessel, and a trailing segment having a proximal end and a distal end;
• a collar comprising a distal band member which is extendable around the graft from an elongate heel segment, the distal band member being adapted to urge the graft against the fitting;
• a first hinge defined between the leading segment and the base, wherein the first hinge is adapted to deflect the leading segment relative to the base when securing the graft to the fitting;
• and
• a second hinge defined between the collar and the base.

A connector loading tool system for preparing an anastomosis connector assembly, the system comprising:

• a loading tool base;
• an outer frame cartridge comprising a flex region having an integral hinge about which a plurality of pins are attached, the pins being adapted to engage an expandable anastomotic connector collar, and an interlock adapted to secure the outer frame cartridge to the loading tool base;
• and
• an inner frame cartridge having a handle with a snap defined thereon for engaging a slidable mount positioned on the loading tool base in apposition to the outer frame cartridge, the inner frame cartridge being adapted to engage an anastomotic fitting which is configured to receivingly engage the expandable connector collar;
• wherein the loading tool base is configured to advance the inner frame cartridge towards the outer frame cartridge until the expandable connector collar is engaged with the fitting.

An anastomosis deployment tool assembly, comprising:

• a handle block having at least one actuator positioned therewithin;
• an elongate shell attached at a distal end of the handle block, the shell defining a lumen therethrough;
• an elongate rod having a proximal end, a distal end, and a length therebetween, the proximal end being positioned within the handle block and pivotally connected to the at least one actuator such that movement of the actuator correspondingly advances the rod within the shell lumen;
• a biasing mechanism located within the handle block which is adapted to bias the rod in a non-advanced position relative to the shell;
• a stabilizer attached to a distal end of the shell, wherein the stabilizer defines a first and a second pivot;
• and
• a first deflector rotatably attached to the first pivot of the stabilizer and a second deflector rotatably attached to the second pivot of the stabilizer;
• wherein advancing the rod distally through the shell actuates movement of the first deflector and the second deflector.

An anastomosis connector placement tool comprising:

• a handle portion;
• and
• an active portion having at least a first and a second extension extending from the handle portion,
• wherein the first extension is adapted to engage a trailing segment of an anastomosis connector and the second extension is adapted to engage an expandable collar of the connector and manipulate the collar via actuation of the handle portion.
