Publication number: 20160354579Abstract: A method and apparatus for fluid delivery enables navigation through tortuous, spatially restricted body anatomy to access narrow diameter body lumens for the continuous delivery of fluids, including therapeutic fluids, to the lumen in an atraumatic manner that avoids damage to the body lumen. The fluid delivery device can have a flexible conduit having a proximal end, a distal end, and a lumen extending along an interior of the flexible conduit providing a fluid flow path between the proximal and distal ends, where the lumen transitions into a micro-lumen exiting through a port through which a high concentration of fluid injected into the lumen exits laterally out along an image viewable zone at the distal end of the flexible conduit. The flexible conduit has a maximum outer diameter sized sufficient to navigate narrow diameter body lumens.Type: ApplicationFiled: May 2, 2016Publication date: December 8, 2016Applicant: ATRIUM MEDICAL CORPORATIONInventors: Steve A.

Publication number: 20160074148Abstract: A hernia patch supporting tissue in-growth conforms to a tissue wall upon surgical installation and fixation within a patient. The hernia patch can include a base and positioning straps. The base is formed of two layers that are affixed to each other around the perimeter of the patch, for example by stitching. A stabilizing washer is provided between the two layers, and the stitch is provided peripherally around the stabilizing washer, keeping the washer free-floating between the layers. The base, positioning straps, and stabilizing washer are formed of a structure that does not separate the layers of the implant or form a space in the form of a pocket, and promotes more uniform and confluent tissue incorporation or in-growth after implantation. The hernia patch may further include a hydrolysable bioabsorbable cross-linked coating of a fatty acid based material, such as an omega-3 fatty acid based material.Type: ApplicationFiled: November 23, 2015Publication date: March 17, 2016Applicant: ATRIUM MEDICAL CORPORATIONInventors: Anthony R.

Publication number: 20150273189Abstract: A method of making a radially expandable fluid delivery device includes providing a tube of biocompatible fluoropolymer material with a predetermined porosity based on an extrusion and expansion forming process, applying a radial expansion force to the tube expanding the tube to a predetermined diameter dimension, and removing the radial expansion force. The tube is radially inelastic while sufficiently pliable to be collapsible and inflatable from a collapsed configuration to an expanded configuration upon introduction of an inflation force, such that the expanded configuration occurs upon inflation to the predetermined diameter dimension. The fluid delivery device is constructed of a microporous, biocompatible fluoropolymer material having a microstructure that can provide a controlled, uniform, low-velocity fluid distribution through the walls of the fluid delivery device to effectively deliver fluid to the treatment site without damaging tissue proximate the walls of the device.Type: ApplicationFiled: June 9, 2015Publication date: October 1, 2015Applicant: ATRIUM MEDICAL CORPORATIONInventors: Steve A.
