Publication number: 20190159879Abstract: A prosthesis and a method of manufacturing the prosthesis for controlling flow through a bodily lumen are provided. The prosthesis includes a body having a proximal portion, a distal portion and a lumen extending therethrough. The prosthesis also includes a valve operably connected to the body. The valve has a proximal portion, a distal portion and a lumen extending through the valve, where the valve lumen is connected to the body lumen. The valve is configured to be closed in the absence of an antegrade pressure and a retrograde pressure, the retrograde pressure being greater than the antegrade pressure. The valve includes a material portion operably connected to the valve, the material portion providing increased stiffness to the valve relative to the valve alone, wherein the material portion is configured to facilitate self-reversion of the valve to the closed configuration.Type: ApplicationFiled: February 1, 2019Publication date: May 30, 2019Applicant: Cook Medical Technologies LLCInventors: Alison Liddy, Michael Ryan, Gerard Treacy, Ger Houlihan, Shay Lavelle, John Neilan

Patent number: 9320502Abstract: A medical device for collecting cells includes an inflatable balloon and a perforated sleeve surrounding the balloon. The sleeve includes a plurality of openings therein for collecting cells when inserted into a body cavity. The balloon and sleeve can be housed in a sheath in a compressed delivery condition for being delivered to a target site for cell collection. The balloon and sleeve can then be inflated to expand into contact with the target site. The openings in the sleeve create a mildly abrasive surface for enhancing cell collection while limiting patient trauma. The balloon and sleeve can be reciprocated back and forth to collect cells from the surface of the body cavity. The balloon and sleeve having the collected cells can then be deflated and retracted from the body cavity.Type: GrantFiled: March 12, 2013Date of Patent: April 26, 2016Assignee: Cook Medical Technologies LLCInventors: Donagh O'Sullivan, Alison Liddy
