20110071466 | HIGHLY EFFICIENT BREASTPUMP AND SYSTEM FOR EXPRESSING BREASTMILK - The present invention provides a breastshield for use in a breastpumping system for expressing milk, the breastshield being of such a construction that substantially limits the amount of air between the breast/nipple and the breastshield surrounding the breast/nipple, and most preferably virtually eliminates any air at least in the area of the breast and nipple. In some embodiments, any air in the breastpumping system is substantially eliminated. With the amount of air limited, the mechanism used for generating the pressure difference in the breastshield (e.g., vacuum or negative pressure), such as a diaphragm pump, does not need to do as much work. Less energy is required for the expression of milk, and thus the size of pump used can be decreased, thereby reducing the overall cost of the device. | 2011-03-24 |
20110071467 | PROBE FOR FLUID LEAK DETECTION WITH MULTIPLE LAYERS - A disposable medical probe for detecting a leak of physiological fluid comprising: a support layer, a conductive layer on top of the support layer, the conductive layer comprising two conducting electrodes both placed exclusively on each side of a longitudinal axis, a hydrophilic layer on top of at least a part of the conductive layer, where the conductive layer defines two zones: a proximal zone where two proximal electrode parts being are placed parallel to each other and being spaced apart by a distance d, and a distal zone where two distal electrode parts are symmetrical with respect to said longitudinal axis and are spaced apart from each other by a gap e greater than said distance d. | 2011-03-24 |
20110071468 | Systems and methods for applying a selected treatment agent into contact with tissue to treat sphincter dysfunction - Systems and methods apply a selected treatment agent or agents into contact with tissue at or in the region of a dysfunctional sphincter (in the case of GERD, fecal incontinence, or other dysfunctional sphincter disorders) to affect improved sphincter barrier function and/or to disrupt abnormal nerve pathways. The treatment agent can include at least one cytokine and/or at least one tissue bulking agent and/or at least one vanilloid compound to evoke a desired tissue response. The systems and methods can be used a primary treatment modality, or applied as a supplementary treatment before; during or after a primary intervention. | 2011-03-24 |

20110071470 | NEW SAFE LATCHING TYPE SELF-DESTROYING SYRINGE - The present invention relates to a new self-locking self-destroying safety syringe, which comprises a hollow barrel, a push rod sliding within the barrel, a rubber plug in front of the push rod, and a needle seat in front of the barrel. The push rod is provided with a round platform, which is provided with an elastic ratchet that slantingly extends toward the inner wall of the barrel. The barrel is provided at the end with an increasing-diameter portion. At the transient position between the normal-diameter portion and the increasing-diameter portion of the barrel is located a slanting step, below which is a groove where the elastic ratchet can be catched when the push rod is drawn backward. The increasing-diameter portion of the barrel is provided inside with a circlip that can press against the bottom of the round platform. For a syringe with the above-mentioned structure, the push rod can be locked after injection in the following way: The push rod is provided with the elastic ratchet that extends to the inner wall of the barrel; the elastic ratchet gets stuck into the groove when the push rod is drawn backward; the slanting step above the elastic ratchet prevents the push rod from moving forward, while the circlip below the elastic ratchet presses against the bottom of the round platform of the push rod so as to prevent the push rod from moving backward; and under the action of the groove, the elastic ratchet cannot move radially either. | 2011-03-24 |
20110071471 | Reversible Cap For Pen Needle Outer Cover - A pen needle assembly includes a cap for covering the non-injection end of a needle of a pen needle. The needle is received by a hub, which is disposed in an outer cover. The cap is adapted to be connected to the outer cover in a first or second position. The cap is removable in the first position and the cap is locked to the outer cover in the second position. | 2011-03-24 |
20110071472 | SYSTEMS FOR ANCHORING A MEDICAL DEVICE IN A BODY LUMEN - A system for securing a device in tissue, having a sheath having a plurality of side openings; a rotatable element disposed within the sheath; and a plurality of curved projections extending from the rotatable element, wherein rotation of the rotatable element within the sheath pushes distal ends of each of the curved projections outwardly through one of the plurality of openings and into the tissue. | 2011-03-24 |
20110071473 | SURGICAL PORT FEATURE - A robotic surgical system is configured with rigid, curved cannulas that extend through the same opening into a patient's body. Surgical instruments with passively flexible shafts extend through the curved cannulas. The cannulas are oriented to direct the instruments towards a surgical site. Various port features that support the curved cannulas within the single opening are disclosed. In one aspect, surgical instrument channels extend at different angles between top and bottom surfaces of a port feature. In another aspect, a funnel portion and a tongue portion are separated by a waist portion, and surgical instrument channels extend from the funnel portion through the waist portion. Cannula support fixtures that support the cannulas during insertion into the single opening and mounting to robotic manipulators are disclosed. A teleoperation control system that moves the curved cannulas and their associated instruments in a manner that allows a surgeon to experience intuitive control is disclosed. | 2011-03-24 |
