Abstract of the Disclosure

An implantable analyte sensor including a sensing region for measuring the analyte and a non-sensing region for immobilizing the sensor body in the host. The sensor is implanted in a precisely dimensioned pocket to stabilize the analyte sensor in vivo and enable measurement of the concentration of the analyte in the host before and after formation of a foreign body capsule around the sensor. The sensor further provides a transmitter for RF transmission through the sensor body, electronic circuitry, and a power source optimized for long-term use in the miniaturized sensor body.

Devices and methods for improved soft tissue securement are disclosed, and, in particular, to tissue anchoring elements and deployment thereof. Such tissue anchoring elements may comprise a linkage element and an array of spreading elements. Endoscopic devices and methods are disclosed for deploying multiple anchoring elements to multiple sites and manipulating at least some of the associated linkage elements to approximate selected sites. Applications of such endoscopic devices and methods may include endoluminal therapy such as gastroplasty, which may be used for the treatment of obesity and gastroesophageal disease. Such devices and methods may also include the attachment of a foreign body to a tissue mass. Further aspects of the invention include devices and methods for the modification of mechanical properties of the anchoring sites so as to decrease the likelihood that anchoring elements will pull out. Such modification may include irritating or injuring the tissue within the anchoring sites, thereby causing a healing or scarification response, or may alternatively include deploying a solidifying agent within the anchoring sites.

Disclosed herein are biointerface membranes including a macro-architecture and a micro-architecture co-continuous with and bonded to and/or located within at least a portion of the macro-architecture. The macro- and micro-architectures work together to manage and manipulate the high-level tissue organization and the low-level cellular organization of the foreign body response in vivo, thereby increasing neovascularization close to a device-tissue interface, interfering with barrier cell layer formation, and providing good tissue anchoring, while reducing the effects of motion artifact, and disrupting the organization and/or contracture of the FBC. The biointerface membranes of the preferred embodiments can be utilized with implantable devices such as devices for the detection of analyte concentrations in a biological sample (for example, from a body), cell transplantation devices, drug delivery devices, electrical signal delivering or measuring devices, and/or combinations thereof.

A method of estimating a position of a foreign object in the body, comprising: (a) providing a 3D data set of at least one blood vessel; (b) acquiring at least one 2D projection image of the vessel including the object; (c) registering the 2D projection image of the vessel to the 3D data set; and (d) using the registration to estimate a 3D position of said object restricted to be in a blood vessel, according to said 3D data set.

An implantable sensor for use in measuring a concentration of an analyte such as glucose in a bodily fluid, including a body with a sensing region adapted for transport of analytes between the sensor and the bodily fluid, wherein the sensing region is located on a curved portion of the body such that when a foreign body capsule forms around the sensor, a contractile force is exerted by the foreign body capsule toward the sensing region. The body is partially or entirely curved, partially or entirely covered with an anchoring material for supporting tissue ingrowth, and designed for subcutaneous tissue implantation. The geometric design, including curvature, shape, and other factors minimize chronic inflammatory response at the sensing region and contribute to improved performance of the sensor in vivo.

An extraction device for the removal of clots and foreign bodies from vasculature. The extractor device is connected to an elongate mandrel and is located within a longitudinally extending lumen defined by a catheter. A clot or foreign material extracted from a vessel by moving the extraction device and catheter proximally until the clot or foreign material does not perfuse a critical organ.

An imaging method, executed at least in part by a computer, tracks the disposition of surgical supplies used in an operation and identifies a radiographic imaging technique for detecting a retained surgical foreign object according to the tracking. One or more radiographic images are acquired in the operating room. The acquired image content is analyzed to identify one or more candidate foreign objects. At least a portion of the acquired image content is displayed with the one or more candidate foreign objects in the acquired image content highlighted.

An intrasaccular device particularly adapted for treating body lumens. The intrasaccular device includes structure that provides a strong framework as well as improved covering across an opening to an aneurysm sac. The intrasaccular device is intended to retain foreign bodies within the aneurysm sac and includes members for accomplishing this objective. The intrasaccular device is also provided with structure that facilitates the alignment of a plurality of devices deployed within the sac.

Devices, systems and methods for removing foreign bodies within a body lumen are disclosed. An unfolding balloon catheter may include an elongated shaft having an intussuscepting balloon that can be actuated within a body lumen to capture and retrieve an intravascular device. The balloon may be configured to radially and/or axially expand when inflated, enveloping the intravascular device. In certain embodiments, the balloon may be formed by folding the ends of a distensible member inwardly, and then bonding the ends of the distensible member to the elongated shaft to form an expandable sleeve. An adhesive layer located along a portion of the elongated shaft may be used to temporarily secure the balloon to the elongated shaft.

A low-profile surgical implant assembly is provided that includes a connector device that is an integral part of a rod, the connector device allowing the rod to be attached directly to a bone screw, such as a pedicle screw.

The assemblies are useful for insertion into bone and connecting a foreign object to bone via a polyaxial coupling mechanism. A method for implanting the assembly is also provided.

Biocompatible materials are propelled at the skin with sufficient velocity to cause desired resurfacing of skin layers to the desired penetration depth. The materials, such as dry ice or water ice, are harmonious with the human body and thus eliminate foreign body reactions. Various materials may be used in combination, including local anesthetics and vasoconstrictors in solid or liquid form. The biocompatible solid or liquid particles are suspended in a cold carrier fluid and propelled through an insulated delivery system to the surface of the skin. The treatment of diseased skin lesions may be accomplished using the present invention as a drug delivery system.
