Abstract: A device for draining cysts includes a catheter system configured to deploy an absorbent material, including but not limited to a foam, into a cyst. The absorbent material advantageously absorbs fluid contained within the cyst, for example fluid that may remain following aspiration, reducing the potential for cyst recurrence. In various embodiments, the absorbent material may be bioabsorbable, radiolucent, echogenic, drug eluting, or a combination thereof. In some embodiments the device may further include or be coupled to a vacuum source which applies negative pressure to the cyst during foam delivery, thereby reduce the overall size and/or profile of the cyst.

Abstract: A medical device, for example a delivery catheter, may include a handle portion, a shaft portion extending distally from the handle portion, a deployment mechanism, and an actuation member positioned on the handle portion. The shaft portion may include a working channel and a distal tip portion having a payload chamber configured to receive a payload, such as a bio-absorbable foam. The distal tip portion may be operatively connected to the working channel. The deployment mechanism may be positioned in the working channel, and may be operable to deploy the payload out from the distal tip portion. The actuation member may be actuatable to operate the deployment mechanism.

Abstract: A biopsy forceps device includes a control member; a yoke coupled to the member; jaws coupled to the yoke; and a capsule. In an open configuration, the jaws are separated to receive target tissue. In a closed configuration, cutting edges of the jaws are moved toward one another to cut tissue. The capsule slidably receives the yoke and a portion of the jaws. The jaws are constrained to the closed configuration when withdrawn proximally to a first position within the capsule. When the jaws are moved to a second position, portions of the jaws are freed from the constraint capsule and spread apart. When the yoke and the jaws are moved distally and the jaws move to the open configuration, a tissue contacting structure of the yoke extends distally to engage tissue between the jaws to anchor the engaged tissue again lateral movement as the jaws contact the tissue.

Abstract: A device includes an elongated hollow member having an open distal end for receiving tissue therein and at least one exterior groove for loading at least one ligation band thereon. The device also includes a band deployment sleeve slidable over the exterior of the hollow member and configured to move from a radially expanded position to a radially contracted position in which, when the band deployment sleeve slides longitudinally over the hollow member, the distal portion engages the at least one ligation band.

Retracting the closing sleeve proximally over the distal portion of the band deployment sleeve releases the distal portion from the radially contracted position into the radially expanded position.
