Patent number: 8920388Abstract: An apparatus provides feedback regarding the material in which tip of the apparatus is located as the tip is advance into matter of varying resistances. The apparatus responds to a change in pressure, force, or other parameter such that when the tip reaches matter of a certain resistance, a change in the parameter is sensed. The apparatus provides a driving force to a penetrating medical device, such as a needle, when the apparatus tip encounters material of high resistance. When the apparatus tip encounters a low resistance material, no further driving force is applied to the apparatus. An inner core may be advanced into the low resistance material for deployment of a gas or a liquid as desired.Type: GrantFiled: February 7, 2008Date of Patent: December 30, 2014Assignees: Massachusetts Institute of Technology, The Brigham and Women's Hospital, Inc.Inventors: Alexander Slocum, Erik Bassett, Jeffrey M.

Patent number: 8764713Abstract: A method of repositioning an injection port comprises positioning the injection port at a first location in a patient's body and extending fasteners of the injection port to substantially secure the injection port at the first location. The fasteners are then retracted to substantially unsecure the injection port from the first location in the patient's body. The injection port is then moved to a second location in the patient's body. The fasteners are then re-extended to substantially secure the injection port at the second location in the patient's body. The injection port includes a port body. The fasteners are integral with the port body. The fasteners may be selectively extended and retracted relative to the port body. For instance, the fasteners may be pivoted relative to the port body to transition between extended and retracted positions.
