<link>http://www.freepatentsonline.com/7364566.html</link>
<description><![CDATA[A renal flow system injects a volume of fluid agent into a location within an abdominal aorta in a manner that flows bi-laterally into each of two renal arteries via their respectively spaced ostia along the abdominal aorta wall. A local injection assembly includes two injection members, each having an injection port that couples to a source of fluid agent externally of the patient. The injection ports may be positioned with an outer region of blood flow along the abdominal aorta wall perfusing the two renal arteries. A flow isolation assembly may isolate flow of the injected agent within the outer region and into the renals. The injection members are delivered to the location in a first radially collapsed condition, and bifurcate across the aorta to inject into the spaced renal ostia. A delivery catheter for upstream interventions is used as a chassis to deliver a bilateral local renal injection assembly to the location within the abdominal aorta.]]></description>

<link>http://www.freepatentsonline.com/7364569.html</link>
<description><![CDATA[A retractable safety syringe includes a needle set, a barrel and a plunger. The needle set is attached to the barrel, and has a first engaging portion at one end. The plunger is mounted with a compressive piston and terminates in a second engaging portion. The piston contacts with a shoulder of the barrel as the plunger is pushed forward. To withdraw the need set inside the barrel, the plunger is pushed forward while the piston contacts with the shoulder of the barrel so as to engage the first and second engaging portion. The plunger is thereby locked with the needle set for withdrawal inside the barrel.]]></description>

<title><![CDATA[Systems and methods for detecting tissue contact and needle penetration depth]]></title>
<link>http://www.freepatentsonline.com/7364567.html</link>
<description><![CDATA[Systems and methods for determining tissue contact and penetration depth are provided. In one aspect, the system includes a needle and a pressure measurement assembly. The needle, in one exemplary embodiment, includes a first end and a second end with at least one aperture located a predetermined distance from the first end. The pressure measurement assembly is connected with a portion of the needle to measure pressure of fluid flowing through the needle. The pressure measurement assembly measures a first pressure when the needle contacts tissue and a second difference in pressure when the needle penetrates the tissue and the aperture becomes occluded.  In an alternative aspect, the system includes a needle and a sensor. The sensor, in another exemplary embodiment, is coupled with a portion of the needle to detect tissue contact pressure on the sensor as the needle penetrates tissue and makes contact with the sensor. The sensor is located a predetermined distance from the first end of the needle.]]></description>

<title><![CDATA[Controlled enzymatic removal and retrieval of cells]]></title>
<link>http://www.freepatentsonline.com/7364565.html</link>
<description><![CDATA[Method and device, including a uniquely operative applicator, and pharmaceutical compositions, for the controlled, non-surgical removal and retrieval of cells from a variety of skin lesions and tissue surfaces are disclosed. A synergistic effect of proteolytic digestion of the intracellular matrix and “stripping” flow is achieved by treating a defined area with a controlled, continuous stream of proteolytic enzyme solution, causing gentle but effective tissue erosion. Isolated cells from the skin lesion and/or tissue surface may be collected from the protease solution stream for histological analysis and/or cell culture, affording a method of “enzymatic biopsy”. The protease solution may be supplemented with anesthetics, coagulants, anticoagulants and antibiotics to decrease the discomfort, erythema, bleeding, risk of infection and scarring traditionally associated with surgical treatment of skin lesions. Delivery of precise levels of catalytic activity is ensured by controlled activation of stable, inactivated enzyme stock solutions and powders shortly prior to application.]]></description>

<title><![CDATA[Flow restrictor device for a medical apparatus]]></title>
<link>http://www.freepatentsonline.com/7364571.html</link>
<description><![CDATA[A medical apparatus flow restrictor includes a housing having an inlet and an outlet, and a fluid path defined through the housing between the inlet and the outlet. At least one pair of opposed restriction devices are seated within the housing between the inlet and outlet. The restriction devices have opposed surfaces placed in contact against each other and are disposed in the flow path such that fluid delivered through the inlet passes between the opposing surfaces prior to flowing from the outlet. The opposing surfaces have a relative degree of surface roughness and opposed surface area defined as a function of a desired flow rate of fluid through the restrictor.]]></description>

<title><![CDATA[Method and apparatus for pressurizing a body cavity for diagnostic and rehabilitative purposes]]></title>
<link>http://www.freepatentsonline.com/7364573.html</link>
<description><![CDATA[A method and apparatus for both the diagnostic measurement and therapeutic treatment of a body cavity. According to one form of the method of the invention, a fluid (liquid or gas) under pressure is introduced into a selected body cavity while monitoring the pressure or flow of the fluid (liquid or gas) into the cavity. Following pressurization of the body cavity, fluid (liquid or gas) inflow and outflow data is collected and analyzed. The data collected is used to draw various conclusions about the biomechanical properties of the body cavity and the organ in which it is present, and also to draw conclusions about presence or absence of disease as well as the character of disease. According to another method of the invention a fluid (liquid or gas) is controllably infused into the body cavity to controllably expand the body cavity for purposes of therapeutic treatment.]]></description>

<description><![CDATA[A pant shaped garment having a rear portion, a front portion, and a crotch portion, a waist opening with a waist edge and two leg openings bordered by a leg edge having a front part located generally on the front portion and a rear part located generally on the rear portion and on the crotch portion. Front and rear portions are mutually connected in two side joins which run from the waist opening to each leg opening. An elongated elastic element is pre-stretched along the rear part of the leg edge of each leg opening. The front portion comprises an elastically extensible material and the elongated elastic element constricts the rear part of the leg edge, thereby stretching the elastic material along the front part of the leg edge. The side joins exhibit a curvature in a direction towards the rear portion that increases in a direction from the waist opening towards the leg opening.]]></description>

<link>http://www.freepatentsonline.com/7364564.html</link>
<description><![CDATA[Various embodiments of MEMS flow modules that may be disposed in a flow path ( 296 ) of a shunt ( 290 ) are disclosed, where the shunt ( 290 ) may be used to control a flow out of an anterior chamber ( 284 ) of an eye ( 266 ). One such MEMS flow module ( 58 ) has a tuning element ( 78 ) and a lower plate ( 70 ). A plurality of springs or spring-like structures ( 82 ) interconnect the tuning element ( 78 ) with the lower plate ( 70 ) in a manner that allows the tuning element ( 78 ) to move either toward or away from the lower plate ( 70 ), depending upon the pressure being exerted on the tuning element ( 78 ) by a flow through a lower flow port ( 74 ) on the lower plate ( 70 ). The tuning element ( 78 ) is disposed over this lower flow port ( 74 ) to induce a flow through the MEMS flow module ( 58 ) along a non-linear (geometrically) flow path.]]></description>

<title><![CDATA[Systems and methods using multiple solvents for removal of lipids from fluids]]></title>
<link>http://www.freepatentsonline.com/7364658.html</link>
<description><![CDATA[This invention is directed to systems and methods for removing lipids from a fluid or from lipid-containing organisms from a fluid, such as plasma. These systems combine a fluid with at least one extraction solvent, which causes the lipids to separate from the fluid or from the lipid-containing organisms. The separated lipids are removed from the fluid. The at least one extraction solvent is removed from the fluid or at least reduced to a concentration enabling the fluid to be administered to a patient without undesirable consequences. Once the fluid has been processed, the fluid may be administered to a patient who donated the fluid or to a different patient for therapy.]]></description>
