Patent number: 10010251Abstract: An intravascular sensor delivery device for measuring a physiological parameter of a patient, such as blood pressure, within a vascular structure or passage. In some embodiments, the device can be used to measure the pressure gradient across a stenotic lesion or heart valve. For example, such a device may be used to measure fractional flow reserve (FFR) across a stenotic lesion in order to assess the severity of the lesion. The sensor delivery device has a distal sleeve configured to pass or slide over a standard medical guidewire. Some distance back from the sensor and distal sleeve, the device separates from the guidewire to permit independent control of the sensor delivery device and the guidewire. The sensor delivery device can be sized to pass over different sizes of guidewires to enable usage in coronary and peripheral arteries, for example.Type: GrantFiled: August 24, 2015Date of Patent: July 3, 2018Assignee: ACIST Medical Systems, Inc.Inventors: Dale R. Manstrom, Amy R. Raatikka, Robert F. Wilson, Edward R. Miller, Jung Kwon Pak

Patent number: 8409273Abstract: Devices, systems, methods and kits are provided for endoscopically accessing a body cavity and providing a directed pathway toward a target tissue within the cavity. The directed pathway is provided by a multi-catheter guiding system which is positioned in a desired configuration, generally directed toward the target tissue. Interventional devices may then be passed through the guiding system to the target tissue. Depending on the location of the target tissue and the desired angle of approach, the guiding system may be required to maintain one or more curves in one or more planes to properly direct the interventional devices. The multi-catheter guiding system of the present invention comprises an outer guiding catheter and a coaxially positioned inner guiding catheter, each of which independently form curvatures so that together the curves properly direct the interventional device.Type: GrantFiled: October 30, 2007Date of Patent: April 2, 2013Assignee: Abbott Vascular IncInventors: Troy L.

Patent number: 8123703Abstract: The present invention provides devices, systems, methods and kits for endoscopically accessing a body cavity and providing a directed pathway toward a target tissue within the cavity. The directed pathway is provided by an access sheath which is positioned in a desired configuration, generally directed toward the target tissue. Depending on the location of the target tissue and the desired angle of approach, the access sheath may be required to maintain one or more curves in one or more planes to properly direct the interventional devices. In addition, the access sheath has a locking feature to hold the sheath in place and maintain the desired configuration. Interventional devices may then be passed through the sheath to the target tissue.Type: GrantFiled: February 3, 2010Date of Patent: February 28, 2012Assignee: Evalve, Inc.Inventors: Brian B.
