System and method for implanting a catheter

A system for inserting a catheter comprising:

• a catheter having a proximal portion, a distal portion, an internal channel and a valve disposed in said catheter wherein the valve comprises:
• a valve first opening, a tool having an extendible element and a tip member, wherein the tip member comprises:
• a tip member first opening adaptable to align with the valve first opening;
• and an extendible element passing through the tip member first opening and the valve first opening, thereby locking the tip member and the valve together.

A system for inserting a catheter comprising:

• a catheter having a proximal portion, a distal portion, a valve disposed in said catheter, and an internal channel;
• a tool having an extendible element that is adapted to extend through the valve and the internal channel to the proximal portion of the catheter;
• wherein the element is releasably attached to a proximal portion of the catheter and capable of imparting one or more of push, pull or torsional forces to the proximal portion of the catheter;
• a tip member mounted on the tool adapted to couple the tool to the catheter, wherein the element extends through the internal channel and through the tip member, and wherein the tip is configured to impart a torsional force and a pull force to the distal end of said catheter;
• and
• a mechanism mounted on the tool to apply extending and retracting forces to the element such that the element and the catheter are in states of elevated stress when the mechanism extends the element and the tool is coupled to the catheter or in states of lessened stress otherwise.

A method for implanting an intraurethral magnetically valved catheter in the urethra comprising the steps of:

• providing a flexible catheter having a proximal end tip and a valve operable in response to an external magnetic field;
• passing an element through said catheter to engage said proximal end tip of said catheter in which said element is extendible and retractable to place the catheter between stressed and relaxed states while maintaining engagement to the catheter proximal tip;
• and
• implanting said catheter in the urethra while said catheter is in said stressed state.

A system for inserting a catheter comprising:

• a catheter having a proximal portion, a distal portion, an internal channel, and a socket tip in the proximal portion;
• a tool comprising an extendible element wherein the extendible element has an outer surface, a proximal portion, a distal portion, and an internal passage extending between the proximal portion and the distal portion;
• at least one opening between the internal channel and the environment at the proximal portion of the extendible element;
• at least one opening between the internal channel and the environment at the distal portion of the extendible element;
• an extendible locking filament sized to fit in the internal passage and slidably disposed within the internal passage of the extendible element from the distal end to the proximal end, wherein the locking filament extends beyond the internal channel;
• wherein the locking filament may exit the internal channel at the proximal portion of the extendible element, engage the socket tip and return to the internal channel at the proximal portion of the extendible element.

A system for inserting a urological catheter in a urinary system, the urinary system having a bladder, a bladder neck, a urethra, and a meatus, the system comprising:

• a catheter having a proximal portion,
• a distal portion;
• an internal channel;
• a valve;
• a structure adapted to fit within the bladder proximal to the bladder neck to arrest distal movement of the catheter;
• and
• a structure distal to the bladder neck to prevent proximal migration of the catheter.

A system for inserting a catheter comprising:

• a catheter having a proximal portion, a distal portion, an internal channel, and a cavity in the proximal portion wherein the cavity includes a engageable member;
• a tool comprising an extendible element wherein the extendible element has an outer surface, a proximal portion, a distal portion, and an internal passage extending between the proximal portion and the distal portion;
• at least one opening between the internal channel and the environment at the proximal portion of the extendible element;
• at least one opening between the internal channel and the environment at the distal portion of the extendible element;
• an extendible locking filament sized to fit in the internal passage and slidably disposed within the internal passage of the extendible element from the distal end to the proximal end, wherein the locking filament extends beyond the internal channel;
• wherein the locking filament may exit the internal channel at the proximal portion of the extendible element, engage the engageable member and return to the internal channel at the proximal portion of the extendible element.

a proximal end having a surface area wherein the projected surface area of the socket tip is from about 2.25 to 3 times the projected surface area of the extendible element. An apparatus comprising:

• an elongated generally tubular structure having an axis wherein the tubular structure comprises:
• an outer surface,
• a proximal end including a fluid inlet, and
• a distal end including a fluid outlet;
• and
• an expandable sealing member disposed on the outer surface of the tubular structure wherein the expandable sealing member comprises
• at least one of an outwardly compliant outer perimeter sealing structure or an axially compliant outer perimeter sealing structure.

An apparatus for preventing migration in biological systems, comprising

• a proximal end;
• a distal end;
• and
• at least one compliant element disposed between the proximal end and the distal end, said at least one compliant element having an outwardly extending length wherein the at least one compliant element interacts with a wall in said biological system, further wherein said at least one compliant element is of a length that in an unstressed state would extend beyond the wall, said wall deflecting said compliant element such that the at least one compliant element creates constant tension between said wall and the apparatus.
