A stent delivery system includes a shaft extending from a proximal end of the system into a delivery tip at a distal end. The shaft includes a coil and a stent bed. A stent is loaded onto the stent bed and has a first portion at its distal end having a greater flexibility than a second portion at its proximal end. Sheathing is movable over the stent bed between pre-deployed and deployed positions. The sheathing includes a flexible section at the sheathing distal end, a semi-flexible section adjacent the flexible section, and a stiff section adjacent the semi-flexible section. The delivery tip is more flexible than the combination of the stent bed, the first portion of the stent, and the flexible section of the sheathing, which is more flexible than the combination of the stent bed, the second portion the stent, and the flexible section of the sheathing.

Method and system for delivering a self-expanding stent to the venous sinuses

A system, method, and computer program product for verifying a purported composition of material in a solid metal object based on heat transfer characteristics. Embodiments include determining, using a group of temperature sensors included in a heat sink, a heat transfer profile for the heat sink when connected to the solid metal object. One or more embodiments include comparing the heat transfer profile for the solid metal object to a baseline heat transfer profile determined based on dimensions of the solid metal object and the purported composition. One or more embodiments include determining, based on the comparing, a difference between the heat transfer profile and the baseline heat transfer profile. And one or more embodiments include indicating that the purported composition is verified in response to determining that the difference between the heat transfer profile and the baseline heat transfer profile is within a threshold.

An device for occluding a body lumen such as a reproductive lumen which includes an occluding component having an impervious barrier to provide initial occlusion of the body lumen and a permeable body to facilitate tissue ingrowth which provides long term occlusion of the body lumen. The device and the method of using the device is particularly suitable for contraception.

Contraceptive with permeable and impermeable components

An introducer sheath/temperature probe assembly that is insertable into a blood vessel of a human or veterinary patent to measure the temperature of blood flowing through that blood vessel. The introducer sheath/temperature probe assembly may be used in conjunction with an indwelling heat exchange catheter system to warm or cool all or a portion of the patient's body to a desired target temperature and to maintain such target temperature for a desired period of time.

Vascular sheath with temperature monitoring probe

Systems and methods for accurate temperature modification of a patient, or selected regions thereof, including inducing hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette attached to the circulatory flow lines of the catheter, the heat exchange cassette being sized to engage a cavity within a control unit. A temperature measurement scheme for obtaining body core temperature is provided, including methods of obtaining and analyzing temperature data to provide feedback to the control unit for use in controlling the heating and cooling of the heat exchange medium so as to heat or cool a patient to a desired target temperature.

System and method for determining and controlling core body temperature

A delivery system for delivering an occluding device to a body lumen comprises an elongated shaft having a proximal end and a distal end, a delivery means for delivering the occluding device to a desired location within the body lumen, and a flexible atraumatic tip on the distal end of the elongated shaft. The distal end of the elongated shaft is insertable into the body lumen. The atraumatic tip is configured to guide the elongated shaft through the body lumen while avoiding perforation of the body lumen.

Atraumatic catheter tip

Vascular introducer with temperature monitoring probe and systems for endovascular temperature control

A device and method of using the device for contraception or sterilization and particularly for reversible contraception by occluding a reproductive lumen to prevent the passage of reproductive cells through the lumen for a desired period of time until the patient wishes to become fertile again and then be reopened. The occluding member preferably comprises a tubular framework formed from a shape memory material configured to be implanted in a reproductive lumen. The occluding member is implanted within a body lumen, secured to the wall of the reproductive lumen and then collapsed to collapse the wall and occlude the lumen. Alternatively, the occluding member may be collapsed upon a solid plug. The closure of the reproductive lumen may be reversed by introducing a balloon catheter and by a series of inflations of the balloon reexpanding the collapsed occluding member or by removing the plug. The occluding member and the plug may be configured to facilitate endothelialization, to provoke an inflammatory responses or to deliver a drug.

Contraceptive system and method of use

A system and method of occluding a reproductive body lumen () to prevent the passage of reproductive cells through body lumen is disclosed. The system can include a catheter delivery system () having a handle device (), a catheter () operatively coupled with the handle device (), and an occluding device adapted for deployment within the body lumen. The handle device can include a damper device adapted to reduce the vibration on the handle device from deployment of the occluding device from the catheter. Further, the handle device can include an indexing member operatively coupled with the catheter to provide indexing of the catheter.

Occlusion device and system for occluding a reproductive body lumen

Systems and methods of visibly marking a reproductive tract, e.g., at least one ostium of the Fallopian tubes accessed transvaginally and transcervically, to indicate delivery of an occlusion device into the corresponding at least one Fallopian tube to effect contraception are disclosed. Marking is effected by delivery of a dye that stains the ostium and/or extension of the marking member from the delivered occlusion device into view in the uterine cavity or ostium. A catheter (or catheters) preferably introduced through a hysteroscope that illuminates and provides visualization of the uterine cavity and the ostia of the Fallopian tubes is employed to insert each contracted, stent-like, occluding device into each Fallopian tube and to mechanically expand or release to self-expand the occluding device.
