Method and system for use in a lung access procedure to aid in preventing pneumothorax
A method for use in a lung access procedure to aid in preventing pneumothorax includes providing a cannula having a pair of balloons, the pair of balloons including a first balloon longitudinally spaced from a second balloon along the cannula; inserting the cannula along an access opening and through pleural layers, with the first balloon and the second balloon of the pair of balloons respectively positioned on opposite sides of the pleural layers; inflating the pair of balloons with a first amount of a two-component sealant to compress the pleural layers together; and inflating the pair of balloons with a second amount of the two-component sealant that is sufficient to rupture the pair of balloons so as to comingle a first sealant component and a second sealant component of the two-component sealant at the site of the pleural layers so as to adhere the pleural layers together.
1 . A method for use in a lung access procedure to aid in preventing pneumothorax, comprising:
providing a cannula having an elongate shaft and a pair of balloons, the pair of balloons including a first balloon longitudinally spaced from a second balloon along the elongate shaft, the cannula having a lumen, the lumen extending through the elongate shaft;
providing a stylet slidably received in the lumen of the cannula, the stylet having a penetrating end portion configured to extend beyond the cannula in a distal direction;
forming an access opening to an interior of a lung of a patient, the access opening formed between a first and a second rib and extends through a parietal pleura, a pleural space, and a visceral pleura of the patient;
inserting the cannula and the stylet along the access opening and through the pleural layers of the patient;
imaging the pair of balloons through use of an imaging system;
determining a current location of the first balloon relative to the parietal pleura and a current location of the second balloon relative to the visceral pleura;
positioning the first balloon to be located proximal the parietal pleura;
positioning the second balloon to be located distal to the visceral pleura;
actuating an applicator to deliver a first amount of a first sealant component of a two-component sealant to the first balloon and a first amount of a second sealant component of the two-component sealant to the second balloon, whereby actuating the applicator results in a pair of inflated balloons, whereby the pair of inflated balloons results in the compression of the pleural layers together; and
actuating the applicator to deliver a second amount of the first sealant component of the two-component sealant to the first balloon and a second amount of the second sealant component of the two-component sealant to the second balloon, the second amount of the first sealant component is sufficient to rupture the first balloon and the second amount of the second sealant component is sufficient to rupture the second balloon, whereby this second step of actuating the applicator results in a pair of ruptured balloons and the first sealant component and the second sealant component comingling at the site of the parietal pleura and the visceral pleura so as to adhere the parietal pleura and viscera pleura together.
2 . The method of claim 1 , further comprising withdrawing the cannula, the stylet, and the pair of ruptured balloons along the access opening to aid in comingling the first sealant component and the second sealant component of the two-component sealant at the pleural layers and in the access opening.
3 . The method of claim 1 , further comprising:
withdrawing the stylet and the applicator from the cannula before actuating the applicator to deliver the second amount of the first sealant component of the two-component sealant to the first balloon and the second amount of the second sealant component of the two-component sealant to the second balloon; and
inserting an interventional medical device into the lumen of the cannula to perform a lung procedure while the pleural layers are compressed together as a result of the pair of inflated balloons.
4 . The method of claim 3 , further comprising reinstalling the applicator into the lumen of the cannula before proceeding to the step of actuating the applicator to deliver the second amount of the first sealant component of the two-component sealant to the first balloon and the second amount of the second sealant component of the two-component sealant to the second balloon.
5 . The method of claim 1 , wherein the first sealant component comingles with the second sealant component to form a sealant gel.
6 . The method of claim 1 , wherein the first sealant component has at least two N-hydroxysuccinimide (NHS) ester groups and the second sealant component has at least two amine groups.
7 . The method of claim 1 , wherein the first sealant component is polyethylene glycol (PEG) succinimidyl succinate and the second sealant component is taken from a group consisting of albumin, polyethylenimine (PEI), and a functionalized PEG having at least two amine groups.
8 . The method of claim 1 , wherein the steps of inflating are performed by the steps of:
connecting the applicator to the cannula; and
actuating the applicator to simultaneously supply the first sealant component of the two-component sealant to the first balloon and supply the second sealant component of the two-component sealant to the second balloon.
9 . The method of claim 1 , wherein the step of actuating the applicator comprises depressing a plunger handle of a syringe-type applicator.
10 . The method of claim 1 , further comprising moving the cannula in a proximal direction so that the second balloon contacts and pulls the visceral pleura into firm contact with the parietal pleura.
