Patent number: 7828747Abstract: The invention relates to pressure generating units, in particular to pressure generating unit arranged in the hand piece of a vacuum biopsy device in the form of a singe (2). In said units, air intake is open by a piston when said piston (5) is in the rear position thereof in the space of a vacuumed cylinder (11) which is switched for generating a superpressure, thereby initiating the outflow of a tissue liquid by the air introduced into the space of the vacuumed cylinder. For this purpose, the space of the vacuumed cylinder is connected to the space of an atmosphere pressure cylinder (12) arranged behind the piston, by means of a connection line (15), and an absorbing element (14) is placed on the piston axis.Type: GrantFiled: March 1, 2007Date of Patent: November 9, 2010Assignee: C.

Publication number: 20100280805Abstract: A system and method for measuring recirculation of blood in a catheter designed for implantation in a human is described. In one variation, the system comprises an artificial circulatory system and an ultrasonic detection device for measuring and comparing the density of a circulated blood simulant with a later introduced bolus saline. The system may be configured to simulate a human heart by providing the flow, pressure and dimensions of a typical human heart. In addition to simulating the circulatory system of a normal human heart, the system may also be configured to simulate particular negative conditions of a patient, such as stenotic condition, which would affect the recirculation measurement.Type: ApplicationFiled: July 19, 2010Publication date: November 4, 2010Applicant: C.

Publication number: 20100280596Abstract: Disclosed is a system for delivering self-expanding stents to stenting sites within the body, which minimizes trauma to the affected tissue of the patient yet, at the same time, offers the medical practitioner a robust and simple system for stent placement. These technical effects are achieved by providing a catheter which receives the stent at its proximal end and guides it to the stenting site. The catheter serves as a guide catheter and has a tapered distal tip from which the stent emerges at the site of stenting. A stent pusher can be used which abuts the proximal end of the stent inside the guide catheter. The tapered tip can be molded and can be integral with the catheter shaft or bonded to it. The guide catheter can include a figurated portion towards its distal tip. The system has particular application to stenting the carotid artery.Type: ApplicationFiled: May 21, 2010Publication date: November 4, 2010Applicant: C. R.

Patent number: 7824420Abstract: An implantable prosthesis for an anatomical defect, such as a tissue or muscle defect, that promotes tissue or muscle growth into the prosthesis and subsequently strengthens the area of the defect. At least one pocket and preferably two concentric pockets may be provided to aid with manipulating the prosthesis. Where two pockets are used, a barrier or partition exists between the pockets and the outer pocket allows manipulation of the outer periphery. The incidence of postoperative adhesions between a portion of the prosthesis and tissue, muscle or organs may be minimized with the use of a barrier layer. Reinforcing members may be attached to portions of the prosthesis to aid in positioning and deployment in the area of desired coverage without rendering the prosthesis unduly difficult to implant or uncomfortable for the patient. Typically, two concentric members are employed.Type: GrantFiled: May 26, 2004Date of Patent: November 2, 2010Assignee: C.R. Bard, Inc.Inventors: Stephen N. Eldridge, Roger Darois
