Abstract: A closure device closes an opening in a body cavity. The closure device includes a plurality of fibrous tissue engaging members coupled to a proximally extending elongate member, a closure sheath sized to receive the elongate member and slidable over the elongate member to move the fibrous tissue engaging members from an expanded position to a collapsed position, a delivery sheath sized to receive the closure sheath and having a distal end sized to engage the fibrous tissue engaging members in the expanded position, and a closure member having an aperture sized to receive the closure sheath.

Abstract: A closure device closes an opening in a body cavity. The closure device includes a closure member that has an external, tissue-engaging surface formed with tissue engaging surface irregularities. An elongate member is disconnectably connected to the closure member.

Abstract: System and method for coating a medical appliance is provided. In accord with one embodiment, a system for applying a coating to a medical appliance having accessible patterned surfaces is provided. The system may include: a processor, an appliance support, and a solenoid type fluid dispensing head having an electromagnetically controlled valve. In the system, the appliance support may be adapted to hold the medical appliance and to provide direct access for a coating to contact the exposed external patterned surfaces of the medical appliance. The solenoid type fluid dispensing head in this system may move with respect to the medical appliance and may be in communication with a source of coating and with the processor. The processor in this system may contain commands that instruct the solenoid type fluid dispensing head to force coating onto the accessible patterned surfaces of the medical appliance in a pattern that correlates with the accessible patterned surfaces of the medical appliance.

Abstract: A non-woven polymeric matrix for separating leukocytes from a blood sample includes a non-woven three dimensional matrix formed from polymeric fibers having a predetermined pore volume fraction including a defined channel configuration, a predetermined pore size in the range of from about 10 ?m to about 250 ?m, and a plurality of connections between the plurality of fibers. The matrix is configured so as to remove at least about 98% of leukocytes from at least one unit of packed red blood cells. Methods of making and using the matrix are also provided.

Abstract: Medical articles (for instance, a drug delivery patch or an implantable or insertable medical device) are provided that comprise a release region, which in turn comprises (a) polymeric carrier comprising a polymer (for instance, a hydrophobic polymer) and (b) drug loaded nanoparticles, which are dispersed within the polymeric carrier. The drug loaded nanoparticles comprise a layered silicate material (for instance synthetic or naturally occurring smectite clay nanoparticles) and a therapeutic agent (for instance, a hydrophilic or hydrophobic therapeutic agent). Also described are methods of releasing a therapeutic agent to a patient using such medical articles, and methods of making such medical articles.
