A medical device that includes a handle for conveying an agent having particles and a receiver having a first lumen defined by a first end and a second end. The receiver having an axis extending between the first end and the second end. The first end configured to receive the particles from the handle, and the second end in fluid communication with a second lumen having a cross-sectional dimension smaller than a cross-sectional dimension of the first lumen. Each of the cross-sectional dimensions of the first lumen and the second lumen is measured transverse to the axis. The second end is configured to receive the particles from the first end of the receiver. The second lumen is configured to control delivery of the agent to a delivery conduit in fluid communication with the second lumen based on sizes of the particles.

A method for treating target tissue comprises introducing a portion of a surgical device into a patient, the surgical device having a treatment end, positioning the treatment end of the surgical device adjacent to the target tissue, and administering a devascularizing material to the target tissue. The devascularizing material, after a time period, is able to devascularize the target tissue. A surgical device comprises a shaft extending between proximal and distal portions, a treatment end located at the distal portion, where the treatment end administers the devascularizating material to a target tissue.

A medical device comprising a housing defining at least one enclosure for storing agent in a first form, a force applicator within the housing and adjacent the enclosure, a drive mechanism for moving the agent toward the force applicator, wherein the force applicator defines a surface for applying a force to the agent to separate the agent into particles smaller than a size of the first form, and wherein the device defines a lumen for receiving the particles from the force applicator and for receiving a pressurized fluid to propel the particles through the lumen.

A device for delivering an agent may comprise: a housing defining an enclosure. The housing may be configured to store an agent. The device may further comprise an inlet, in fluid communication with the enclosure, for receiving a flow of pressurized fluid; an outlet in fluid communication with the enclosure; and a filter disposed within the enclosure. Pores of a wall of the filter may be configured such that the fluid is permitted to pass through the pores into a channel defined by an inner surface of the wall. An actuation member may be configured to transition between a first configuration, in which portions of the agent disposed proximally to the actuation member are prevented from passing distally of the actuation member, and a second configuration, in which portions of the agent disposed proximally of the actuation member are capable of passing distally of the actuation member.

Methods for protecting a peritoneum or other tissue during a surgical procedure are disclosed. In some embodiments, a protective lining is applied to the peritoneum or other tissue before an active surgical intervention, such as before tissue dissection, tissue approximation, and/or other surgical act. In some embodiments, the protective lining includes a protective film applied to the peritoneum or other tissue via a delivery balloon or via a spray instrument.

A medical system includes a handle, a sheath extending from the handle, and an end effector connected to a distal end of the sheath, where the end effector directs a mass of material towards a target site of a body and cause release of the material onto the target site.

A medical device comprising an enclosure defining a cavity for containing agent, a lumen for receiving a pressurized gas, and a barrier positioned between the cavity and the lumen, the barrier including at least one opening for storing agent, wherein rotation of the barrier relative to the lumen establishes fluid communication between the at least one opening and the lumen for delivering agent from the at least one opening to the lumen.

A device may be configured to deliver an agent to a target tissue via pressurized fluid and the device may include a catheter including a lumen; an enclosure configured to store an agent, receive a pressurized fluid, and release a combination of the pressurized fluid and the agent; and a valve downstream of the enclosure to receive the combination of the pressurized fluid and the agent from the enclosure. The valve may have a first configuration preventing flow of the combination through the lumen and a second configuration permitting flow of the combination through the lumen.

The present invention is directed to multi-liquid loading and delivery kits comprising a first storage vessel for a first active component, a second storage vessel for a second active component, at least two transfer syringes, at least two vial adaptors, at least two cannulas with a through lumen and a multi-liquid delivery device. The delivery device has dual hollow cartridges, each with at least one throughbore at one end and plunger access at the opposing end, a kick stand, a removable dual feed funnel, a spray or drip manifold and at least one spray or drip tip assembly.
