  • Publication number: 20030174807
    Abstract: According to the present invention, improved methods and apparatus are provided for providing cushioning and other ergonomic surfaces on devices requiring the patient or tissue to be compressed, such as radiography machines, fluoroscopy units, mammography units and the like. In particular a radiolucent pad element is provided for releasable attachment to at least one surface of a compression device to be used under x-ray, for example, during mammography. The pad element of the present invention can be disposable or constructed to be reusable and in some cases may be applied directly to the patient's breast.

  • Patent number: 6602240
    Abstract: According to the present invention, improved methods and apparatus are provided for regaining hemostasis or otherwise minimizing leakage during endoluminal, surgical or percutaneous intraluminal procedures, and for providing a seal during laparoscopic surgical procedures where there is leakage of the CO2 insufflation, when the primary means of hemostasis or pneumatic CO2 seal is compromised or fails. More particularly the present invention relates to devices having a front hub and a rear hub, one or other of which is adapted to retain a compression seal such that when the front and rear hub are matingly engaged, axial and radial pressure is applied to the compression plug and any devices located therebetween, thereby achieving a seal. The compression device can be applied while a guidewire or additional devices remain within the leaking sheath or trocar, thereby allowing the physician to maintain hemostasis or adequate CO2 insufflation, without exchanging the introducer sheath or laparoscopic port.

  • Publication number: 20030066597
    Abstract: A method and apparatus (20) for making an absorbent article can include a delivering of a first contoured web-strip (30a) from a first production supply (38) of contoured web-strip material, with the first contoured web-strip (30a) presenting a primary production sequence of side edge contours during its delivery. At least a second contoured web-strip (30b) can be delivered from a second production supply (40) of the contoured web-strip material, with the second contoured web-strip (30b) also presenting the primary production sequence of side edge contours during its delivery. In a particular aspect, the first and second contoured web-strips (30a and 30b) have been produced from a web (22) of absorbent material which has been divided to provided at least two web-strips (30) having a substantially nested configuration.

  • Publication number: 20030037012
    Abstract: A system enables tender of payment manually (e.g., cash, check, etc.) for transactions conducted over a network (e.g., the Internet). The system includes one or more computer systems each located at a corresponding agent site, one or more merchant systems and a server computer system in communication with the agent and merchant systems. The server system accesses the appropriate merchant network or web site in response to transaction selection information received from the agent system, and translates those web pages for transmission to the agent system. The server computer system further receives the required transaction information from the agent system and processes the transaction information for transference to the particular merchant web site. In addition, the server system enters credit card information of a provider of the transaction service within the transaction payment information for transference to the merchant system in order to tender payment for the network transaction.

  • Publication number: 20030007597
    Abstract: A pad for cushioning a compression device, e.g., an x-ray plate, of a mammography unit. The pad includes a radiolucent central region, e.g., including radiolucent orientation markings, that is secured adjacent a contact surface of the x-ray plate. The pad includes a pair of side regions secured along respective side surfaces of the x-ray plate including a slot for inserting an x-ray cassette into the x-ray plate. The pad also includes a front region securable along a front surface of the x-ray plate. A double coated tape may be attached to the pad that includes a pressure sensitive adhesive for removably attaching the pad to the x-ray plate. Alternatively, the side regions may extend around the compression device and connect to one another to secure the pad or the pad may be a sleeve that is slidably received around at least a portion of the compression device.

A first quantity of a first superabsorbent material (30) can be directed to form a selected combination with the first fibrous material to provide a first superabsorbent-containing stratum. A second fibrous stratum (32) of fibrous material can be deposited to overlie the first fibrous stratum (26), and the second fibrous stratum (32) can have a second stratum thickness (34). A second superabsorbent material (36) can be directed to form a selected combination with the second fibrous material to provide a second superabsorbent-containing stratum.
