Patent number: 9277935Abstract: Devices and methods for treating a target site in a body lumen are provided. A medical device includes a stent-like structure including a plurality of scoring and non-scoring filaments interwoven with one another. Generally, the stent-like structure will have more non-scoring filaments than scoring filaments to provide greater structural support and to focus the scoring forces on only a few select areas. The stent-like structure is expanded within the target site to score the target site and to provide temporary structural support while the target site is infused with a therapeutic agent. Such therapeutic agent infusion occurs with the use of a drug eluting or drug coated balloon disposed within the stent-like structure or by occluding the target site and introducing a drug into the occluded target site to sit for a period of time.Type: GrantFiled: November 15, 2013Date of Patent: March 8, 2016Assignee: Quadra Endovascular, Inc.Inventor: Richard Eustis Fulton, III

Patent number: 9114031Abstract: A method of treating a target site within a vascular channel of the body uses a catheter assembly having proximal and distal occluders which are positioned in occluding states at positions proximal and distal of a target site to define an occluded region therebetween. An agent is injected into the region. An intervention is performed at the target site while the vessel is occluded and the agent is in the region. The catheter assembly is removed from the channel. Intervention may include expanding a balloon within a temporary stent structure against the channel, collapsing balloon and then removing the collapsed balloon and stent structure from the channel. A balloon stent assembly comprises a catheter assembly, a temporary stent surrounding a balloon, the temporary stent placeable in a contracted state by the catheter assembly and in an expanded state by inflation of the balloon.Type: GrantFiled: March 31, 2014Date of Patent: August 25, 2015Assignee: QUADRA ENDOVASCULAR, INC.Inventor: Richard E.
