Publication number: 20170079661Abstract: An implant can include a single- or dual-layer braided body having a variable porosity. In a dual-layer body, first and second longitudinal sections, having respective first and second porosities, can be overlapped such that the first and second porosities overlap each other. The dual-layer construction can cumulatively provide a third porosity at a distal portion and a fourth porosity at a proximal portion. The third and fourth porosities can each be greater than each of the first and second porosities.Type: ApplicationFiled: September 23, 2015Publication date: March 23, 2017Inventors: Earl Bardsley, Richard Rhee

Publication number: 20080312664Abstract: A medical device is disclosed for tissue, body lumen and/or cavity closure inside a body of a patient. In one particular application, the medical device can be used for minimally invasive access and closure of a left atrial appendage of the heart. The medical device generally includes a tool used for grasping the appendage, a closure member, and at least one tool to deploy, control, and position the closure member for closing the appendage. The device can also include an expander tool for expanding the working area around the left atrial appendage to improve visibility during the procedure. In other embodiments, the medical device may include other tools, for example an imaging tool for viewing the target area and/or other tools that are considered useful in a left atrial appendage closure procedure.Type: ApplicationFiled: May 12, 2008Publication date: December 18, 2008Applicant: EPITEK, INC.Inventors: Earl Bardsley, Jianlu Ma, Jean Paul Rasschaert, Thomas J.

Publication number: 20080294174Abstract: An access tube has a central passage and at least one lumen extending axially between the central passage and an outside wall of the access tube. The lumen carries therein a piercing member for accessing an anatomic space, such as a pericardial space between the parietal pericardia and the visceral pericardia. While the access tube is positioned against the parietal pericardium, a distal end of the piercing member engages and penetrates the parietal pericardium. The distal end of the piercing member entering the anatomic space can then allow the piercing member to advance and form into a supporting structure to create a working space. After the working space is created, an access device can be introduced through the access tube into the pericardial space to perform a variety of procedures inside a patient.Type: ApplicationFiled: May 12, 2008Publication date: November 27, 2008Applicant: Epitek, Inc.Inventors: Earl Bardsley, Jianlu Ma, Jean Paul Rasschaert
