Abstract: A spray tip for dispensing fluids that react together includes a first lumen for a first fluid, a second lumen for a second fluid, and a dispensing cap located at distal ends of the respective first and second lumens and defining a distal end of the spray tip. The dispensing cap includes a distal end wall defining a closed end of the dispensing cap, a first spray opening formed in the distal end wall that is in fluid communication with the first lumen, a second spray opening formed in the distal end wall that is in fluid communication with the second lumen, and an external dividing wall that projects distally from the distal end wall of the dispensing cap and that extends between the first and second spray opening for forming a barrier between the first and second spray openings.

Abstract: A spray device includes side-by-side spray tips that are spaced from one another at a distal end of the spray device. A first spray tip has a first fluid pathway defining a first flow area. The first fluid pathway has a first swirl chamber having an outer perimeter and flutes having inner ends that direct a first fluid into the outer perimeter of the first swirl chamber for rotating the first fluid in a circular pattern. A second spray tip has a second fluid pathway that defines a second flow area that is larger than the first flow area. The second fluid pathway has a second swirl chamber having an outer perimeter and flutes having inner ends that direct a second fluid into the outer perimeter of the second swirl chamber for rotating the second fluid in a circular pattern.

Abstract: A spray device includes a first spray tip having a first fluid pathway defining a first flow area, and a second spray tip includes a second fluid pathway that defines a second flow area that is larger than the first flow area of the first spray tip. The first and second spray tips are side-by-side and spaced from one another at a distal end of the spray device. When a first fluid having a volumetric flow rate is introduced into the first spray tip and a second fluid having the same volumetric flow rate is introduced into the second spray tip, the first fluid will flow through the first fluid pathway at a greater velocity than the second fluid will flow through the second fluid pathway.

Abstract: Vessel wound closure systems and method for sealing a puncture wound in a target vessel, such as those puncture wounds that occur from prior interventional procedures. A sealing member is deployed intravascularly into the target vessel, and an anchor member is deployed extravacularly of the target vessel. The sealing member and the anchor member are connected by a suture that may be drawn to tighten the sealing member and the anchor member relative to one another in order to effect the seal of the puncture wound. After tightening, the suture is secured to maintain the sealing member and the anchor member relative to one another in order to maintain the seal. Preferably, the anchor member, the suture and the sealing member are comprised of biocompatible, bioresorbable materials that are absorbed into the body after the sealing of the puncture wound has been achieved.

Abstract: The invention provides punctal plugs for the delivery of active agent to one or both of the tear fluid of the eye and to the nasolacrimal duct. The plugs of the invention have a body, a reservoir contained within the body, and optionally a collarette. The reservoir has at least one opening and contains a polymeric material and at least one active agent.

Abstract: The invention relates to a customizable, solvent-free sustained release medical device for wound closure, wound healing, and the sustained release of an active. The device of the invention is composed of at least a polymeric carrier layer and optionally an oxidized regenerated cellulose layer(s). Polymeric barrier layers can be added to modify the release profile (burst, time of release, etc.) of the selected bioactive agent(s).

Abstract: The invention provides devices useful for the delivery of active agents to the eye in a controlled manner. In the devices of the invention, the active agent is present within the device in a continuous or discontinuous concentration gradient.

Abstract: A device comprises a needle, probe, holster, and tissue collection chamber. A motor simultaneously powers a vacuum pump, translates and rotates a cutter, and translates a plunger. The needle includes a piercing tip and an interior shelf that divides the needle into a cutter lumen and lateral lumen. The cutter and shelf include apertures configured to mince a portion of a tissue specimen that has been severed by the cutter and forced through the apertures by compressive force from the plunger as well as vacuum force. The apertures of the shelf and the apertures of the rotating cutter cooperate to shear the tissue being compressed by the plunger. The minced tissue is then transported to the tissue collection chamber under vacuum force with the assistance of a fluid flush. Collected minced tissue may then be further processed as desired for a given medical treatment or procedure.
