A method of constructing a detachment system for delivering an implantable medical device to a target location of a body vessel is presented. The method includes forming a compressible portion on a distal tube, engaging an implantable medical device with an engagement system, extending the engagement system through the distal tube such that the implantable medical device is distal of a distal end of the distal tube, applying a force to the engagement system to compress the compressible portion to a compressed state, fixing the engagement system to the distal tube to maintain the compressed state of the compressible portion, and joining a proximal end of the distal tube to a distal end of a proximal tube. The engagement system can include a loop wire that is fixed to the distal tube and engages the medical device.

Occlusive implants are provided with various embodiments of active and/or passive release structures. Systems for delivering the occlusive implants as well as methods for making and delivering the implants are also provided.

Split support catheters, loading tools, and methods of use are disclosed. A support catheter can include an elongate tubular member and a push member. The tubular member can comprise a longitudinal slit configured to accommodate the exchange of various interventional devices into and out of the lumen defined by the tubular member. A loading tool can comprise a body member, a rod member, or both and can facilitate loading of the support catheter onto one or more interventional devices during a medical procedure. The support catheters can provide intravascular support to various interventional devices and can advantageously be inserted and removed without first removing an interventional device having its distal end at or near a target site within a patient's vasculature.

A portable hand-held medical device includes a body having a gun-type formation that includes a barrel. A guide wire device is housed in the body and is configured to advance and retract through the barrel. The guide wire device carries a bundled arrangement including a video system, an illumination system to support the video system, a fluid irrigation line, and a guide wire mechanism. The bundled arrangement is packaged as a unit in an insertion tube. The tip section of the insertion tube incorporates a camera, a light source, and a fluid irrigation port. A catheter is disposed at the end of the barrel, so that during operation the guide wire device passes through the catheter lumen. The combination guide wire device and catheter enter the urinary tract and perform a bladder evacuation process.

A guide extension catheter comprising a proximal reinforcing section that is completely surrounded by, or encased within, a polymer covering or coating the proximal reinforcing section, and further comprising an exemplary semi-circular flared section disposed proximal to the proximal reinforcing section, wherein the flare is interrupted by a flattened bottom. The proximal reinforcing section is configured to interconnect with a flat ribbon which is connected with or defines a proximally extending push rod. The proximal reinforcing section does not extend beyond the proximal-most end of the exemplary semi-circular flared section

The present invention relates to a safety puncturing system comprising a cannula and a guidewire.

A thrombectomy catheter with a catheter or delivery sheath having a dual lumen extending therethrough, the catheter having a proximal segment and a distal segment and a linear section coupled therebetween, the distal segment configured as a loop, a port or aperture formed therein said dual lumen of said catheter, the port positioned proximate the distal segment, and a guidewire configured to longitudinally traverse therethrough one of the dual lumen of the catheter, said guidewire having a first end affixed to a mesh strainer, the mesh strainer configured to longitudinally traverse therethrough the other of the dual lumen of the catheter and exit therethrough said port and follow said loop to form retractable mesh strainer.

A delivery device for delivering an catheter into an intravenous catheter assembly may include a housing having a distal end, a proximal end, and a slot. The delivery device may include a catheter having a proximal end and a distal end. The delivery device may include a catheter hub disposed within the housing. The catheter may be secured to the catheter hub. A portion of the catheter hub may extend through the slot and may be moveable along the slot to advance the catheter in a distal direction. The distal end of the catheter may be disposed distal to the distal end of the housing when the catheter is advanced.

A device is configured for closing an aperture in a wall of a blood vessel. An embodiment of the device includes a body and at least one suture element held within the body. A suture capture rod is positioned within the body and is operatively associated with the suture element and arranged to pass the suture element through a vessel wall such that opposed portions of the suture element extend from the vessel wall. A removable guidewire segment is removably attached to a distal end of the body.

A steerable guide wire and/or a catheter device and associated method. The device includes a guide wire having a distal end, a hollow interior, and an anchoring mechanism positioned proximate to the distal end of the guide wire. The device further includes a core wire is slidably inserted into the hollow interior of the guide wire. Upon insertion, the core wire actuates the anchoring mechanism to anchor the guide wire at an anchoring location
