Devices, systems, and methods used to drain a body cavity under a vacuum are disclosed. The devices include a vacuum container and a cap. The container includes an ergonomic gripping portion to allow a user to easily handle the container in use. The cap includes a sealing member configured to selectively seal an inlet to control the flow of drainage fluid into the vacuum container.

Vacuum drainage collection bottle

Devices and methods used to drain a spinal cyst are disclosed. An opening may be created by a medical device, such as a nested needle assembly, that is inserted percutaneously into a facet joint adjacent to the cyst. The needle assembly may include a first elongate member, needle or introducer cannula; a second elongate member, inner cannula, needle, or trocar; and a piercing needle. The piercing needle may be used to microfenestrate a wall of the cyst such that fluid within the cyst is permitted to drain from the cyst.

Nested needles for spinal cyst treatment

Inflatable compression devices are disclosed. In some embodiments the devices provide compression to the torso of a patient, including at a pocket configured to receive a pacing device. In some embodiments at least one securing strap is displaceable with respect to a compression member. In some embodiments a compression member is displaceable relative to at least one securing strap.

Inflatable surgical compression device and related systems and methods

Devices used to deliver a substance within a patient's body are disclosed. The devices may include a microcatheter configured to deliver the substance to a targeted site. The microcatheter may include an expandable member to temporarily restrict blood flow in a vessel, a flow restriction member to restrict flow of material out a distal end of the microcatheter, and a port disposed proximal of the expandable member.

Microcatheter occlusion embolization catheter

Retrievable vena cava filters for the temporary or permanent prevention of Pulmonary embolism (PE) are disclosed. A filter in accordance with the present invention has a tube-within-tube structure with overlapping semi-spheres. The semi-spheres comprise a plurality of expandable legs. The first tube may have a first set of expandable legs and a plurality of slots allowing for deployment of a second or third set of expandable legs on the second tube. The filter of the present invention may be retrieved by a catheter and snare. The third set of expandable legs conveys the vector force from the closing of the first set to the second set to cause it to collapse.

Percutaneous retrievable vascular filter

Retrievable vena cava filters for the temporary or permanent prevention of Pulmonary embolism (PE) are disclosed. A filter in accordance with the present invention has a tube-within-tube structure with overlapping semi-spheres. The semi-spheres comprise a plurality of expandable legs. The first tube may have a plurality of slots allowing for deployment of a first or second sets of expandable legs on the second tube. The free end of each leg in the first set of expandable legs may be oriented in a direction the same as or opposite to the free end of each leg in the second set. The filter may also be formed from a single tube. In certain embodiments, the filter of the present invention can be retrieved from either end.

The free end of each leg in the first set of expandable legs is oriented in a direction opposite to the free end of each leg in the second set forming a cage which comprises legs from the first and second sets of expandable legs. The filter of the present invention may be retrieved by a catheter and snare. The third set of expandable legs conveys the vector force from the closing of the first set to the second set to cause it to collapse.
