Embodiments of the invention include a medical instrument with a sealing device. In embodiments, the medical instrument is endoscopic device having a seal between an elongate shaft member and/or on a portion of a handle to, for example, prevent flow communication between a lumen of the elongate member and the external environment.

Instrument with sealing device and methods of advancing fluid therethrough

A rapid exchange catheter comprises a guide wire lumen including a substantially sealed portion in which a lumen wall extends around an entire periphery thereof and a channel portion including a channel opening the lumen to an exterior of the catheter, wherein a width of the channel is less than a maximum width of the channel portion. A guide wire ramp extends into the channel portion, with the ramp extending further into the lumen of the channel portion as a distal end of the ramp is approached.

Method for forming a rapid exchange catheter with formed guide wire ramp

A rapid exchange catheter extends from a proximal portion which remains outside of a patient's body during use to a distal portion which, during use, is located within a body lumen adjacent to a target area to be treated, wherein the proximal and distal portions are coupled by a medial portion. The catheter comprises a guide wire lumen extending longitudinally through the distal portion and a guide wire receiving channel formed by an outer surface of the medial portion, wherein the guide wire lumen is open to a distal end of the channel.

Rapid exchange catheter with depressable channel

Embodiments of the invention include a medical instrument with a sealing device. In embodiments, the medical instrument is an endoscopic device having a seal between an elongate shaft member and/or on a portion of a handle to, for example, prevent flow communication between a lumen of the elongate member and the external environment.

A locking device for a maintaining an elongated member at a selected place within a body lumen includes a substantially rigid body including an attachment portion adapted to be coupled to a proximal portion of a medical instrument. When in an operative position, the distal portion of the medical instrument is received within the body lumen and a head coupled to the substantially rigid body. The head is configured to overlie an access port of the medical device when the attachment portion is coupled to the proximal portion of the medical device in a predetermined configuration. A plurality of locking features extends from the head to immobilize a section of the elongated member relative to the medical device.

Guidewire locking device and method

Locking device that is mounted on an endoscope or the like for selectively securing the position of a guide wire and/or catheter relative to the endoscope or the like. The locking device preferably includes a side wall with an opening therein for receiving the proximal end of a guide wire or catheter. The opening is preferably J-shaped or boot shaped, and has an entry end and a locking end. Once a guide wire or catheter is in a desired position within a body cavity, the portion of the guide wire or catheter that extends outside of the endoscope or the like may be moved into the opening. More particularly, a portion of the guide wire or catheter may be inserted by an operator through the entry end of the opening and into the locking end, wherein the locking end frictionally secures the position of the guide wire or catheter relative to the endoscope or the like.

Guidewire and catheter locking device and method

The present invention provides an apparatus for, and a method of, accurate positioning of endoscopic instruments. Accurate positioning of the instruments is accomplished through the inclusion of a steering ability within the device. After the endoscopic instrument is properly positioned the present invention may use rapid exchange technology, soft locks, and mechanical locks to maintain the position of the endoscopic instrument. Rapid exchange technology is used to minimize displacement forces present on the guidewire or catheters. Soft locks and mechanical locks resist movements caused by displacement forces.

Method of and apparatus for positioning and maintaining the position of endoscopic instruments

Catheter with formed guide wire ramp

A locking device for a maintaining an elongated member at a selected place within a body lumen comprises a substantially rigid body including an attachment portion adapted to be coupled to a distal portion of a medical instrument wherein, when in an operative position, the distal portion of the medical instrument is received within the body lumen and an angled head coupled to the substantially rigid body, the angled head being configured to overlie an access port of the medical device when the attachment portion is coupled to the distal portion of the medical device in a predetermined configuration in combination with a plurality of locking features extending from the angled head to immobilize a section of the elongated member relative to the medical device and a locking arm extending from the locking device so that, when the attachment portion is coupled to the medical device, the locking arm extends between the access port and the locking features to guide the elongated member from the access port to the locking features along a desired path.
