A catheter includes a handle and an elongate member extending from the handle. The catheter may also include steering system coupled to the handle. The steering system may be configured to deflect at least a portion of the elongate member in at least one direction. The catheter may also include a locking mechanism configured to lock the portion of the elongate member in a deflected configuration, and a lever coupled to the handle. The lever may be configured to move from a first position to a second position to engage the locking mechanism. The lever may also be configured to be separably retained at least at one of the first position or the second position to prevent movement therebetween.

Steerable catheter with brake assembly

A medical device may include an elongate member, and a plurality of grasping members extending from the elongate member. Each of the grasping members may include a proximal end, and a distal end. Each of the grasping members may include at least one first section formed of a first material and a second material, and a second section located at the distal end of the grasping member. The second section may be formed without the first material and being less stiff than the at least one first section.

Medical retrieval devices and related methods of use

Described herein are various systems and methods for directing endoscopy instruments to varying positions at a target site. In one aspect, at least one instrument channel has multiple exit points at the distal end of the guide tube, and the position of an instrument delivered through the channel may be switched between the different exit points. In another aspect, an instrument channel splits into multiple branches at the distal end of the guide tube, and the position of an instrument at the target site may be changed by selectively directing the instrument into a different channel branch. In yet another aspect, the guide tube, or a portion thereof, may be rotated to reposition an instrument at the target site. The capability of changing the instrument positions during a procedure would enable a physician to examine or treat multiple target sites within an operative field, without necessitating the full retraction of the instruments or the guide tube from the operative field.

A medical prosthesis having a low profile for delivery into a body lumen is disclosed. The stent includes a plurality of wire strands woven to form a plurality of joints at the intersections, some of which are helically wrapped. The helically wrapped joints may be offset form the joints of a second plurality of wire strands concentric to the first. Alternatively, the helically wrapped joints can doubled forming box nodes.

Low profile medical stent

The present invention relates to a medical prosthesis having a low profile for delivery into a body lumen. The stent includes a plurality of geometric cells defining the stent, which has first and second opposed open ends; and a plurality of wire strands woven to form a plurality of crossed regions defining the geometric cells. Each wire strand has strand ends and the strand ends are disposed at the second end of the stent.

A mold for a medical device balloon has a cavity adapted to receive a hollow parison expandable therein to form the balloon. The cavity has a cone region and a body region. The cone region is heated to a higher temperature, or the mold wall is formed to deliver applied heat more efficiently to the cone region, relative to the body region of the mold.

Catheter balloon molding device

A medical device system includes a catheter, an expandable prosthesis over the catheter, and a holding material between the catheter and the prosthesis. The holding material initially holds the prosthesis over the catheter.

Medical devices

The present invention relates to a system for delivering a medical prosthesis into a body lumen. A preferred embodiment of the invention utilizes a catheter having a stent mounted at the distal end that is released into the body lumen by movement of an outer sheath covering the stent in the proximal direction. The stent expands to conform to the inner wall of the lumen and the catheter is withdrawn.

Stent delivery system

Low polymer stress balloons are made by expanding a tube radially while allowing the ends of the tube to move axially in response to the radial expansion.

Medical balloon

A balloon for a medical device has a structural layer of a highly crystallized PEN polymer material. The PEN polymer material a polyethylene naphthalate homopolymer or a crystallizable copolyester made up of residues of ethylene glycol, naphthalene dicarboxylic acid (NDC) and at least one member of the group (PA) consisting of terephthalic acid and isophthalic acid. The NDC groups make up about 5% or more of the sum of NDC and PA groups in the copolymer. The balloon is characterized by an ability to withstand a hoop stress of at least 35,000 psi without bursting.
