Patent number: 10258376Abstract: A tool for manipulating a foreign body (e.g., a deployed medical device) can include an operative portion. The operative portion can be used to move the foreign body in the proximal and/or distal directions with respect to the removal/repositioning tool and/or the tissue surrounding the foreign body. In some embodiments, the tool can include a compressing portion that can be used to compress the foreign body as the foreign body is pulled by the operative portion in the proximal direction. The tool can further include a sleeve that can be used to transition the operative portion and/or compressing portion between an opened configuration and a closed configuration. In some embodiments, the tool can be used in conjunction with an endoscope to navigate the tool to the site of a foreign body within the body of a patient.Type: GrantFiled: September 26, 2014Date of Patent: April 16, 2019Assignee: Spiration, Inc.Inventors: David H. Dillard, Clinton L. Finger, Erik Liljegren, Desmond O'Connell, Richard O. Shea, William A. Sirokman

Patent number: 10201442Abstract: A valve loading system is provided that uses a valve loader to transfer a valve or other medical device from a storage cartridge into a deployment catheter. The valve or other medical device can be implanted or positioned within a patient using the catheter after the valve or other medical device has been compressed and loaded into the catheter using the valve loader. The process then can be repeated by using the valve loading system to load or introduce another valve or other medical device into the catheter.Type: GrantFiled: March 13, 2014Date of Patent: February 12, 2019Assignee: Spiration, Inc.Inventors: Erik Liljegren, Desmond O'Connell, Evelyn Hall

Patent number: 10123788Abstract: A deployment catheter is described herein that preferably is configured to deliver a medical device such as a valve to a location in a patient such as a patient's airway. Preferably, such a deployment catheter is configured to be used in conjunction with a bronchoscope. In some embodiments, a locking lever is provided to reduce the likelihood of accidental deployment of the device, and which resets conveniently after use to as to permit multiple device deployments.Type: GrantFiled: July 29, 2014Date of Patent: November 13, 2018Inventors: Desmond O'Connell, Erik Liljegren, David H. Dillard, Hugo X. Gonzalez
