Various embodiments disclosed relate to a device for insertion into the urethra for dilation. The present disclosure includes methods and devices including a device for at least partial insertion into a prostate, the device including first and second elongated members each having at least one magnetizable or magnetic element. The first and second elongated members are magnetizable to repel each other to dilate a lumen therebetween.

Embodiments of the present invention provide medical devices and methods for treating a target site within the body. For example, one embodiment provides a stent graft for treating a target site proximate to a bifurcated lumen, wherein the stent graft includes a first tubular structure having proximal and distal ends and a side wall extending therebetween. The first tubular structure includes an opening defined within the side wall and is configured to define a first portion having first and second ends and a second portion having first and second ends. The opening corresponds to the first ends of the first and second portions and the second ends of the first and second portions respectively correspond to the proximal and distal ends of the first tubular structure, and at least a portion of the first and second portions are configured to be positioned within respective branches of a bifurcated lumen.

Nonwoven resorbable pouches that at least partially enclose implantable medical devices and improved methods for producing the implantable medical device pouches are described. The nonwoven pouches may comprise one or more drugs. Implantable medical devices that are placed in the pouches prior to implantation are prevented from migrating from the site of implantation by tissue ingrowth into the pouch. Antibiotics may be incorporated into the pouches to prevent post-operative infections. The pouches may be formed in fewer steps than conventional pouches, and without polymer coatings. Nonwoven pouches can be formed in one step by dry spinning instead of using multiple processing steps. In embodiments, the nonwoven pouches are smoother on the inside than the outside to tightly fit the implantable medical devices internally while encouraging external tissue ingrowth. In embodiments, the nonwoven pouches eliminate the use of knitted or woven multifilament fibers that can trap bacteria and result in post-operative infection.

This invention relates to novel implant drug delivery systems for long-acting delivery of mometasone furoate. These compositions are useful for the treatment or prevention of inflammatory conditions of the eye.

The invention relates to a balloon catheter comprising a shaft (2) extending in the longitudinal direction, which has at least a first and a second section (7, 8), with the first section (7) being arranged distal to the second section (8) and being more flexible than the second section (8), with the shaft (2) being provided with a first and a second hose-like tube (10, 11) and a balloon (3) being arranged at the distal end of the first tube (10), said balloon (3) being expandable by pressurization with a fluid led through said first tube (10), and said second tube (11) serving for accommodating a guidewire and terminating distally of said balloon (3) and being provided with an opening at said distal end, wherein both said first and second tubes (10, 11) extend along said first and second sections (7, 8), and both said first and second tubes (10, 11) are more flexible in said first section (7) than in said second section (8), wherein a transition section (9) is arranged between said first and second sections (7, 8), in which the first tube (10) has the same material properties as in the first section (7) and the second tube (11) has the same material properties as in the second section (8) or the first tube (10) has the same material properties as in the second section (8) and the second tube (11) has the same material properties as in the first section (7).

An implant that may maintain position with a Eustachian tube of a patient, the implant includes an engagement body, an anchoring assembly, and a pressure balance assembly. The engagement body includes an exterior surface dimensioned to bear radially outward against the Eustachian tube. The anchoring assembly may lock the implant in the Eustachian tube. The pressure balance assembly includes a vented pathway that may transition between an occluded state and a vented state. The vented pathway may provide fluid communication between the proximal end and the distal end of the implant in the ventilated state while inhibiting fluid communication between the proximal end and the distal end of the implant in the occluded state.

Adaptive graft assemblies and methods of manufacture and implantation are provided herein. In particular, such grafts can be 3D printed and can be defined as standard designs or patient-specific, external sheaths customized for specific vein graft dimensions following minimally/non-invasive vein mapping and computational modeling. The external sheath may include one or more layers of various biomaterials to produce customized biomechanical properties. The external sheath may be made to elute specific bioactive drugs allowing for pharmacologic prevention of adverse remodeling in addition to mechanical support. These customizable features may be tailored for each patient individually depending on specific medical history, including hypertension, diabetes, smoking history, anatomy or any pertinent patient attribute. These methods protect vascular grafts, specifically venous grafts, from immediate exposure to arterial pressure that can induce adverse remodeling and graft failure, thereby providing a precision medicine solution to cardiovascular bypass surgery.

A surgical device includes a substrate and a first coating that covers at least a portion of the substrate. The first coating includes a first polymer. The first coating having antibiotics dispersed in the first polymer such that the first polymer releases the antibiotics as the first polymer degrades. A second coating covers at least a portion of the first coating. The second coating includes a second polymer. The second coating has ellagic acid dispersed in the second polymer such that the second polymer releases the ellagic acid as the second polymer degrades. In some embodiments, systems and methods are disclosed.

The present invention is an inflatable balloon which is enclosed by an expandable cover which becomes increasingly porous/permeable during expansion. The balloon is coated or enclosed with a matrix which contains a pharmaceutically active agent. During expansion of the balloon, the pharmaceutically active agent is released or extruded through the expandable cover into a body cavity such as an artery or vein. The present invention also provides for a method of treating a disease or condition by delivering the inflatable balloon to a particular body cavity.

Hernia meshes are provided as well as methods of use thereof and methods of making.
