摘要： An access and delivery device and system configured to facilitate access and delivery of an implantable device to a deployment site. The system includes a tissue-penetrating element and an access and delivery device with an anchor member configured to flex outwardly transverse to the tissue-penetrating element. The system may pass through a proximal non-adherent anatomical structure to a deployment site in a distal non-adherent anatomical structure. The anchor member may be used to maintain the relative positions of the non-adherent anatomical structures and/or to protect the deployment site from a tissue-penetrating end of an implantable device delivery and deployment system. The tissue-penetrating element may have a soft distal tip configured to engage tissue walls atraumatically, such as to protect a tissue wall from a sharp tissue-penetrating end of the tissue-penetrating element.

摘要： The present disclosure relates generally to systems and methods for performing endoscopic procedures, and, more particularly, to location and access devices, systems, and methods for gastrojejunostomy procedures. In an aspect a medical device locator may include an elongate member having a proximal end, a distal end, a longitudinal axis, and a length extending along the longitudinal axis. An inflatable member may be disposed about the distal end of the elongate member. The inflatable member may have a first inflated volume and a second inflated volume larger than the first inflated volume. The elongate member may include a fluid lumen extending therealong. The fluid lumen may be in fluid communication with the inflatable member and may be configured to pulsate the inflatable member between the first inflated volume and the second inflated volume.

摘要： An implantable device configured to withstand forces imparted thereto by anatomical structure at a deployment site. The implantable device includes an outer portion and inner portion. The outer portion is positioned between the inner portion and the walls of the anatomical deployment site. The outer portion may enclose the inner portion. The outer portion may be a compliant balloon compressible in response to radially-inwardly directed anatomical forces exerted thereon. The inner portion may include one or more portions configured to retain the implantable device at the deployment site and to resist migration of the implantable device. The inner portion may be movable with respect to the outer portion. The inner portion may include more than one portions, such portions being movable with respect to each other. A shaft may extend through the device, such as to facilitate inflation of the outer portion and/or positioning of the inner portion.

摘要： An implantable device having an adjustable passage therethrough. The passage may be adjustable to occlude or otherwise to regulate access or flow of materials therethrough. An elongated element may be inserted into the passage when in a closed configuration to selectively open the passage. For instance, the implantable device may be a tubular device with a twisted region closing the passage therethrough, and the elongated device may be configured to engage such twisted region and to be rotated to untwist the closed region. An additional tubular device with a passage therethrough may be inserted into the passage of the implantable device to hold open the passage for a selected period of time.

摘要： A medical device may comprise a handle and a flexible sheath extending from the handle. The sheath may include a first chamber configured to receive a first agent and a second chamber configured to receive a second agent. Each of the first chamber and the second chamber may be disposed in a distal portion of the sheath. The sheath may also include a first piston received within the first chamber and a second piston received within the second chamber and at least one actuation element configured to transmit a force from the handle to each of the first piston and the second piston. When the handle is in a first configuration, the first agent may be maintained within the first chamber and the second agent is maintained within the second chamber. When the handle is in a second configuration, the first agent may be released from the first chamber to mix with the second agent.

摘要： An implantable medical device having at least one compliant retention member configured not only to resist migration of the device with respect to its deployment site, but also to conform to anatomical forces applied thereto. The retention member may present a convex tissue-contacting surface to tissue at the deployment site and to which anatomical forces may be applied. The retention member may be compressible upon application of radially-inwardly directed anatomical forces thereto, but is sized, shaped, configured, and/or dimensioned to withstand forces tending to cause migration of the implantable medical device even when being compressed radially-inwardly. As such, the implantable medical device withstands forces applied thereto without building up internal stresses which may result in material fatigue.

摘要： Devices, systems, and methods for delivering targeted therapy to tissue at a treatment site with the use of a stent. The targeted therapy may include a functional and/or therapeutic agent separate from the stent, or a component of a functional and/or therapeutic agent separate from the stent and reactive with another component of a functional and/or therapeutic agent on the stent. The agent or component of an agent may be delivered with the stent, and/or before delivery of the stent, and/or after the stent has been delivered.

摘要： An implantable flow-restricting device, extending along a longitudinal extent which need not be linear, and having a first portion and a second portion with a saddle region therebetween. At least one of the first or second portions may be angled with respect to the saddle region to resist migration of the device. At least one of the first or second portions may be configured to maintain a distance from a region of the anatomical structure in which such portion is positioned. An occluder, such as an expandable occluder, may be associated with the flow-restricting device, such as with one of the first or second portions thereof. The occluder may serve to block passage of material through the anatomical passage in which the saddle region is positioned, prevent migration of the device (e.g., through such passage), and/or increase volume occupied by the device.

摘要： A medical system including a compressible device, and a covering over the compressible device, wherein the covering includes a delivery configuration and a deployed configuration, wherein, in the delivery configuration, the covering at least partially covers the compressible device to maintain the compressible device in a compressed state, and wherein, in the deployed configuration, the covering is releasable from the device to transition the compressible device from the compressed state to an expanded state.

摘要： An access needle includes a hollow shaft having a lumen sized and shaped to slidably receive a guidewire therein and having a distal end including an angled surface extending proximally and transversely from a sharpened distal-most tip of the shaft to a beveled smoothed area of the shaft proximal and transverse to the sharpened tip. The beveled smoothed area is positioned to slidably engage a guidewire extended distally out the distal end of the needle so that, as the guidewire is retracted proximally into the needle, the beveled smoothed area slidably engages the guidewire to minimize abrasion to the guidewire.
