Endoluminal drug delivery device

A drug delivery device (10) includes expandable element (12) formed of a braided structure having a body portion (16) and first and second end cones (18, 20). The end cones are attached at their necks (22, 24) to a catheter assembly (14). The expandable element (12) can expand to a vessel contacting configuration, in which the body portion (16) contacts the vessel wall. Bioactive agent (28) covers at least the outer surface of the body portion (16) such that bioactive material can be administered to a vessel wall. The end cones (18, 20) have an open structure allowing unrestricted passage of blood through the device (10) in the deployed configuration, such that blood flow can be maintained during the administration of bioactive agent (28) from the device (10). The expandable element (12) can be radially contracted by extending it in the longitudinal direction, both for deployment endoluminally to the treatment site and also for retrieval following the administration of the bioactive material.

09744057 · 2017-08-29 ·

A special tube is disclosed for the insertion of materials inside the maxillary sinus in order to displace the Schneiderian membrane. The tube is connected to a source of a flowable material. The tube is inserted through the alveolar ridge beneath the maxillary sinus and when the flowable material is advanced through the tube the Schneiderian membrane is lifted. The tube can be part of a dental implant which is screwed inside the alveolar ridge.

Sensors for prosthetic heart devices

An implantable device system includes an implantable device, such as an annuloplasty ring, for controlling at least a shape and/or size of a heart valve annulus. The implantable device includes an arcuate body and an adjustment system configured to adjust the shape and/or size of the arcuate body. An adjustment tool is configured to be coupled to the adjustment system so that the adjustment tool can be used to activate and control adjustment of the arcuate body. A sensor system is configured to be coupled to the implantable device. The sensor system includes a first sensor configured to measure physiological data at an inflow portion of the valve annulus when the implantable device is implanted into the valve annulus, and a second sensor configured to measure physiological data at an outflow portion of the valve annulus when the implantable device is implanted into the valve annulus.

Filter with deployable anchors

An implantable and removable filter that may be implanted in and/or removed from a body lumen, such as the Vena Cava. The filter including tissue anchors on expandable anchoring legs, which can be selectively moved between a non-anchoring or pre-deployed configuration into an anchoring or deployed configuration by obturators that are movable inside the anchoring legs.

Actively controllable stent, stent graft, heart valve and method of controlling same

Sealable and repositionable implant devices are provided to increase the ability of endovascular grafts and valves to be precisely deployed or re-deployed, with better in situ accommodation to the local anatomy of the targeted recipient anatomic site, and with the ability for post-deployment adjustment to accommodate anatomic changes that might compromise the efficacy of the implant. A surgical implant includes a self-expanding stent of a shape-memory material set to a given shape. The stent has a wall with a portion having a first thickness and a second portion having a thickness greater than the first. The second portion defines a key-hole shaped longitudinal drive orifice. The implant includes a selectively adjustable assembly having adjustable elements and being operable to force a configuration change in at least a portion of the self-expanding stent. The adjustable elements have a part rotatably disposed within the longitudinal drive orifice.

In-situ formed intervertebral fusion device and method

An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.

Stent designs to cover catheter access site

Methods, apparatuses and systems are described for delivering a stent through an access hole of a body lumen and covering up the access hole after deploying the stent, Stents are described that include a stent body defining a body lumen contact surface area and a deployable member configured to deploy from the stent body and increase the body lumen contact surface area of the stent. Deployable members that hinge, unroll, extend, expand, and coaxially translate with respect to the stent body are described. A system for delivering a stent into a body lumen are described that may include a coverage member configured to at least partially cover the hole in the wall of the stent upon withdrawing a tubular member through the hole in the wall of the stent. Coverage members may include a self-sealing membrane, a flap valve, or a hinged valve.
