Abstract
In one embodiment the apparatus includes a first retractor, a second retractor, and a shaft. The shaft defines a central channel extending from a first end portion of the shaft to a second end portion of the shaft. The first retractor and the second retractor are configured to collectively form a lumen. The shaft is configured to be disposed within the lumen. In one embodiment method of disposing a graft within a body of a patient, includes making an incision in the body of the patient, inserting a medical device into the body of the patient through the incision, removing the shaft of the medical device from the body of the patient, and moving the first refractor within the body of the patient away from the second retractor.
Claims16
An apparatus, comprising:
- a first retractor having a handle portion and a blade portion, the handle portion extending from the blade portion in a direction different than a longitudinal axis of the blade portion of the first retractor, the blade portion of the first retractor having an inner surface, the inner surface of the blade portion of the first retractor including a first ridge protruding from the inner surface and spaced apart from lateral edges of the blade portion of the first retractor;
- a second retractor having a handle portion and a blade portion, the handle portion extending from the blade portion in a direction different than a longitudinal axis of the blade portion of the second retractor, the blade portion of the second retractor having an inner surface, the inner surface of the blade portion of the second retractor including a second ridge protruding from the inner surface and spaced apart from lateral edges of the blade portion of the second retractor;
- a shaft defining a central channel extending from a first end portion of the shaft to a second end portion of the shaft, the shaft having an outer surface defining a first groove and a second groove, the central channel being disposed between the first groove and the second groove,
- the inner surface of the first retractor and the inner surface of the second retractor are configured to collectively form a lumen, the shaft being configured to be disposed between the first retractor and the second retractor, the first ridge of the first retractor configured to engage the first groove of the shaft, the second ridge of the second retractor configured to engage the second groove of the shaft, the handle portion of the first refractor and the handle portion of the second retractor extending away from each other and extending away from the shaft, the first retractor being configured to move with respect to the second retractor in a direction away from the second retractor.
