Abstract: Method and apparatus for personal isolation and/or protection are disclosed. In one variation, the system may include a passive filtration component having a mask configured for positioning over a mouth and/or nose of a user, wherein the mask has at least one portion configured to filter air passing through the at least one portion. An active filtration component having a fan may be included, wherein the active filtration component is configured to filter air entering or exiting the active filtration component via the fan, and a hose fluidly coupled between the passive filtration component and the active filtration component such that the active filtration component is remote from a face of the user when in use.

Abstract: Devices and methods for treating the prostate are disclosed where in one embodiment, the apparatus generally comprises a catheter which is sized for placement within a body lumen, at least one balloon positioned along a length of the catheter and defining a contact region for thermally contacting a portion of the body lumen which is in proximity to tissue to be treated, and a reservoir in fluid communication with the at least one balloon through at least one lumen defined through the length of the catheter. The at least one balloon may be configured to receive a refrigerant from the reservoir introduced through the at least one lumen until the contact region is at least partially expanded, the catheter being adjustable to selectively align the contact region against the portion of the body lumen to preferentially cool the portion relative to a remainder of the body lumen surrounding the portion.

Abstract: An insertion device for delivering media inside a patient includes an outer guide tube having a side port. An inner guide tube is nested within the outer guide tube and movable axially within the outer guide tube. The inner guide tube includes a deflector at an end within the outer guide tube. The device also includes a catheter nested within the inner guide tube and movable axially within the inner guide tube. The deflector of the inner guide tube is positionable such that it deflects the dispensing end of the catheter outward through the opening in the outer guide tube when the catheter is advanced axially within the inner guide tube. A therapeutic delivery cannula may be nested within the catheter, such that the deflected end of the catheter determines the direction of travel of the therapeutic delivery cannula into patient tissue when the cannula emerges from the catheter.

Abstract: Disclosed is a glaucoma treatment device having a tubular, unbranched portion and a branched portion. The unbranched portion has an internal flow pathway extending between a distal region and a proximal region. The branched portion extends from the distal region of the tubular, unbranched portion. The proximal region of the unbranched portion includes at least one inflow port that is in fluid communication with the internal flow pathway. The branched portion includes a first and a second reversibly deformable branch. Each of the first and second branches has at least one outflow port and an internal lumen in fluid communication with the flow pathway of the unbranched portion. Each of the first and second branches is biased away from one another when in a relaxed state.
