  • Patent number: 10433947
    Abstract: A device for maintaining or achieving soft tissue expansion applicable to any body region already temporarily expanded including: an adhesive element deformable and capable of adapting to the shape of this body region, and which can then itself become mechanically rigid enough to resist tendency of the expanded tissue to recoil or to which a second material can be applied to form a stent adapted to the shape of the body area to provide the necessary structural rigidity to prevent recoil of the expansion and thereby induce its retention of its expanded shape after the stent is removed.

  • Patent number: 8403877
    Abstract: The present invention provides systems and methods for treating and controlling obesity and/or type II diabetes. In one aspect of the invention, an internal bypass device includes gastric and duodenal anchors coupled to each other and positioned on either side of the pylorus and a hollow sleeve designed to extend from the pylorus through at least a proximal portion of a patient's small intestine. The gastric and duodenal anchors are movable between collapsed configurations for advancement through the esophagus and an expanded configuration for inhibiting movement of the anchors through the pyloric sphincter. Thus, the bypass device can be placed and removed endoscopically through the patient's esophagus in a minimally invasive outpatient procedure and it is “self-anchoring” and does not require invasive tissue fixation within the patient's GI tract, thereby reducing collateral tissue damage and minimizing its impact on the digestive process.

  • Patent number: 7601178
    Abstract: The invention relates to an implantable stomach prosthesis for surgically replacing or augmenting all or part of the antrum and/or pylorus of a stomach. The prosthesis controls the passage of food from the stomach to the small intestine. The prosthesis may be configured to chum ingested material and release it from the stomach through a prosthetic pyloric valve. At least one expandable member is arranged to be expanded to control the passage of food and/or to mimic the churning action of a patient's stomach. The prosthesis includes an outer support structure, a flexible inner member forming a conduit for the movement of material, and at least one expandable member located between the outer support structure and inner member. An implantable pump system is provided for inflating and deflating the expandable member(s).

  • Publication number: 20090254195
    Abstract: Partitioning devices that may be secured and sealed within a heart chamber for separating a patient's heart chamber into a productive portion and a non-productive portion are described herein. The partitioning devices described herein may include a reinforced membrane with outwardly biased members. The reinforced membrane may have a central hub with a distally extending support stem with a plurality of feet which extend radially from a centerline axis and preferably have ends that are aligned in a common plane. These devices may be secured within the heart chamber by sealing them to the wall of the heart chamber, for example, by inflating an inflatable element on the periphery of the device. The non-productive portion may be filled with a material, including occlusive materials. Sealing and/or filling the non-productive portion formed by the devices described herein may help prevent leakage from the non-productive region.

    Abstract: Described here are self-expanding devices and methods of using and making them. The devices may be useful in a variety of locations within the body, for a number of different uses. In some variations, the devices have a first compressed configuration enabling low profile delivery through a delivery device, a second expanded configuration for apposition against tissue, and comprise either a single continuous filament or at least two non-intersecting filaments. In some variations, the device is formed into a shape having a series of peaks and valleys. At least one of the peaks and valleys may have a loop at then end thereof. At least a portion of these devices may be capable of biodegrading over a predetermined period of time, and the devices may be configured for drug delivery. Methods of treating one or more sinus cavities are also described here.

  • Patent number: 7350538
    Abstract: A pump assembly for a penile implant is provided having a mechanism which prevents spontaneous inflation of the cylinders implanted within the user. The preventative mechanism uses overpressure generated by the reservoir during unintentional compression to effectively seal the pump assembly from unintended fluid flow. The prevention mechanism itself creates all necessary forces to prevent the undesired fluid flow to the cylinders. This is accomplished by incorporating appropriate mechanisms within the pump itself.
