Abstract: A delivery system for use with a catheter having a catheter proximal end and a catheter distal end. The catheter further has a catheter wall with an outer catheter dimension at the catheter distal end and with the catheter wall defining a catheter lumen with a longitudinal axis extending from the catheter proximal end and through the catheter distal end. The occlusion system includes a shuttle member for snapping onto the catheter and slidable thereon toward the catheter distal end. An elongated delivery member has a distal end connected to the shuttle and movable therewith.

Abstract: An occlusion system is disclosed for use with a catheter having a catheter proximal end and a catheter distal end. The catheter further has a catheter wall with an outer catheter dimension at the catheter distal end and with the catheter wall defining a catheter lumen with a longitudinal axis extending from the catheter proximal end and through the catheter distal end. The occlusion system includes an occlusion member having an inner wall and an outer wall. The inner wall defines an occlusion member lumen extending throughout an axial length of the occlusion member. The outer wall is expandable between a contracted state with a first transverse dimension and an expanded state with a second transverse dimension. The second transverse dimension is greater than the outer catheter dimension.

Abstract: A kit is disclosed for use with a catheter having a catheter proximal end and a catheter distal end. The catheter further has a catheter wall with an outer catheter dimension at the catheter distal end and with the catheter wall defining a catheter lumen with a longitudinal axis extending from the catheter proximal end and through the catheter distal end. At the catheter proximal end, the catheter has a catheter coupling including an access port. The kit includes an occlusion system coupling having a proximal end and a distal end and having a lumen extending there between. The distal end of the occlusion system coupling is adapted to be secured to the catheter coupling access port with the lumen of the occlusion system coupling in communication with a lumen of the catheter coupling. The occlusion system coupling has a port in communication with the lumen of the occlusion system coupling. A deflated occlusion balloon is disposed within the port of the occlusion system coupling.

Abstract: Catheters for introducing fluids into a bodily lumen of a patient are disclosed. The fluids may include medicinal, imaging or other compounds. The catheters include a proximal tube, a core wire and a distal tube. The first end of the core wire is secured to the second end of the proximal tube. The core wire extends through the distal tube. A proximal lumen of the proximal tube is in communication with the distal lumen of the distal tube. A bridge tube may be provided between the proximal lumen and the distal lumen to facilitate communication of the proximal lumen and the distal lumen. The catheter may be configured with a relatively small diameter and low overall profile using aspects of the present inventions. The catheters may include a balloon at a distal end to receive the fluid. The fluid provided through the catheter may inflate the balloon. The catheter may include a distal outlet release a fluid into the patient.

Abstract: Occluding guidewires to access bodily lumen of a patient are disclosed. The occluding guidewires include a slotted tube and a balloon secured to a distal end of the slotted tube. The slotted tube includes a plurality of slots. The slots are in fluid communication with a lumen defined by the slotted tube. The balloon is secured about the slotted tube over one or more slots to permit inflation media to be communicated through one or more slots from the lumen into the inflation chamber of the balloon. The occluding guidewire may also include a proximal tube. A proximal lumen of the proximal tube is in communication with the lumen of the slotted tube. The occluding guidewire may be configured with a relatively small diameter using aspects of the present inventions.

Abstract: Balloon apparatus to access bodily lumen of a patient are disclosed. The balloon apparatus include an inflation tube, a core wire and a balloon. The balloon is secured to a distal end of the inflation tube and a core wire extending from the distal end of the inflation tube passes through a sleeve in the balloon. A proximal tube may be provided at the proximal end of the inflation tube. The balloon apparatus may be configured with a relatively small diameter using aspects of the present inventions.

Abstract: Distal protection filter retrieval devices and methods of retrieving a distal protection filter. A filter retrieval catheter may comprise an inner tube, an outer tube disposed over the inner tube, an annular lumen disposed between the inner tube and the outer tube, and a tapered member coupled to the lumen. The tapered member may be movable between a first position for passing a lesion and a second position retrieving a filter.

Abstract: A medical device with improved flexibility characteristics and methods of using the same. The medical device may include a proximal end, a distal end, and an intermediate region. In at least some embodiments, the column strength or flexibility of the intermediate portion is generally greater than the column strength or flexibility at the distal end.

Abstract: A medical guidewire includes a distal end for entering and navigating in a lumen. The distal end comprises a core having a length for navigating the guidewire in the lumen. A formable distal tip is included at the distal end of the core, and a sleeve element substantially surrounds the core over less than a majority of the length of the core. The sleeve element is rotatable with respect to the core, and is offset proximally of the formable distal tip such that the formable distal tip is movable independently of the sleeve element. The sleeve element is positively coupled to the core such that the sleeve element and the core move substantially conjointly axially within the lumen. An improvement for improving navigability of a medical guidewire in a lumen is also provided. The improvement comprises a sleeve element separate from and disposed around the core. The sleeve element is rotatable with respect to the core. Multiple sleeve elements may be provided on a single core.
