Apparatus and method for protecting a port site opening in the wall of a body cavity

A medical apparatus, comprising:

• a trocar assembly including a cannula and a trocar;
• a sleeve having a sealing member extending therefrom and a passageway extending therethrough, said trocar assembly being positioned within said passageway of said sleeve;
• and
• a lock member which has hole defined therein, said sleeve extending through the hole,
• wherein said sealing member defines a fluid impervious bag,
• wherein said bag has an interior void, and
• wherein a charge of elastically deformable beads are confined within said interior void.

A medical apparatus, comprising:

• a trocar assembly including a cannula and a trocar;
• a sleeve having a number of sealing members extending therefrom and a passageway extending therethrough, said trocar assembly being positioned within said passageway of said sleeve;
• and
• a lock member which has hole defined therein, said sleeve extending through the hole,
• wherein an antibiotic, a cytotoxic agent or a compound which inhibits tumor cell adherence to a membrane is disposed upon the number of sealing members.

A medical apparatus, comprising:

• a trocar assembly including a cannula and a trocar;
• a sleeve having a number of sealing members extending therefrom and a passageway extending therethrough, said trocar assembly being positioned within said passageway of said sleeve;
• and
• an antibiotic, a cytotoxic agent, or a compound which inhibits tumor cell adherence to a membrane disposed upon said sealing members.

A medical procedure, comprising the steps of:

• creating an opening in a wall of a body cavity;
• advancing a medical apparatus through the opening and into the body cavity, the medical apparatus including (1) a sleeve having a number of sealing members connected thereto and a passageway extending therethrough, and (2) a trocar assembly positioned within the passageway of the sleeve, the trocar assembly including a cannula and a trocar;
• positioning the sealing members to contact an interior surface of the body cavity;
• providing a lock member having a hole extending therethrough;
• positioning the lock member such that the sleeve extends through the hole;
• and
• applying the following material to the sealing members:
• an antibiotic, a cytotoxic agent or a compound which inhibits tumor cell adherence to a membrane.
