Abstract

Various devices, systems, and methods are provided for allowing surgical instruments to access a body cavity through an access device, such as a cannula. In one embodiment, a cap can be removably and replaceably coupled to a proximal end of cannula and can have an opening therethrough that communicates with an inner passageway of the cannula. Various surgical elements can be passed through the cap and cannula and into a patient when the cannula is positioned within the patient. The cap can have a side slot formed therein. The slot can be configured to allow surgical elements, such as sutures, to pass through the cap and into the cannula. At least one surgical seal can be in the cap and can be configured to receive surgical elements therethrough.

First claim

What is claimed is:

1. A surgical method, comprising:
positioning a cannula in tissue to form a pathway therethrough such that a surgical instrument can be passed through the tissue by being advanced into a proximal end of the cannula and passed out a distal end of the cannula; and
removing a cap from the proximal end of the cannula such that a surgical element extending through the cannula and through a central opening of the cap passes through a slot formed in a sidewall of the cap and remains extending through the cannula after the removal of the cap, the cap including a sealing element that forms a seal of an inner passageway of the cannula that extends between the proximal and distal ends thereof, and the removal of the cap causing loss of the seal of the inner passageway.

2. The method of claim 1 , further comprising, after removing the cap, re-coupling the cap to the proximal end of the cannula such that the surgical element extending through the cannula passes through the slot and remains extending through the cannula after the re-coupling of the cap.

3. A surgical method, comprising:
positioning a cannula in tissue to form a pathway therethrough such that a surgical instrument can be passed through the tissue by being advanced into a proximal end of the cannula and passed out a distal end of the cannula;
removing a cap from the proximal end of the cannula such that a surgical element extending through the cannula and through a central opening of the cap passes through a slot formed in a sidewall of the cap and remains extending through the cannula after the removal of the cap; and
after removing the cap, re-coupling the cap to the proximal end of the cannula such that the surgical element extending through the cannula passes through the slot and remains extending through the cannula after the re-coupling of the cap.
