An implantable medical pump system configured to selectively permit access to a medicament reservoir by way of at least one contactless key, including an implantable medical pump having an medicament reservoir fluidly couple to an access port via a conduit including an access valve, and at least one contactless key configured to impart a magnetic field upon a portion of the implantable medical pump to manipulate the access valve between a closed position isolating the medicament reservoir from the access port, and an open position fluidly coupling the medicament reservoir to the access port.

A cannula and instrument guide assembly includes a cannula with a proximal portion and a tube, An instrument guide is removably inserted into the proximal portion of the cannula and extends through the cannula to a distal end of the tube. The proximal portion of the cannula has an insufflation port. The instrument guide provides at least one interior passageway to support a shaft of a surgical instrument that passes through the instrument guide. One or more channels on an outer surface of the instrument guide provide a passage for insufflation gas received from the insufflation port to the distal end of the tube, The one or more channels have a first cross-sectional area at a proximal end and a second, larger cross-sectional area at a distal end. The one or more channels may have the first cross-sectional area along a majority of the length of the channels.

A urological device includes a valve retained in a urinary catheter. The urinary catheter has a first portion that is insertable into a urethra and a second portion adapted to remain outside of the urethra when the first portion is inserted into the urethra. The valve has a closed configuration adapted to prevent urine from exiting the urinary catheter and an open configuration adapted to allow urine to flow through and exit the urinary catheter. The valve is adapted to move from the closed configuration to the open configuration in response to a hydrodynamic pressure of at least 750 mm H2O applied to the valve for at least 5 seconds.

Embodiments of a breast pump kit are disclosed herein. The breast pump kit can include one or more of a breast pump shield and a breast pump milk bag. According to various embodiments, the breast pump shield can include a body portion that has a breast engagement portion that can receive at least a portion of a breast of a user. The breast pump shield also can include a suction chamber located in proximity to the breast engagement portion. Milk can pass into the suction chamber and into the breast pump milk bag. A one-way valve can prevent reverse flow of fluids from the breast pump milk bag into the breast pump shield. The breast pump kit also can include a cover that can seal the breast pump shield, if desired.

An integral seal system includes a body that defines a central opening, and an asymmetric seal extending into the central opening and including a diaphragm and an annular flange that extends between the body and the diaphragm, wherein the diaphragm has a cross-sectional thickness larger than a cross-sectional thickness of the annular flange. A duckbill seal extends distally from a bottom of the body and defines one or more parting lines that separate opposing seal flaps. The diaphragm complements insertion and extraction drag forces generated by the duckbill seal against a surgical tool shaft extended therethrough such that total insertion and extraction drag forces generated by the integral seal system are equalized.

A diagnostic imaging catheter is disclosed which includes a drive shaft, of which a distal portion is provided with a signal transmitting and receiving unit, and which can be rotated; a sheath including a lumen into which the drive shaft is inserted such that the drive shaft can be moved forward and backward; a communicating hole which is provided in a distal portion of the sheath, and through which the inside and the outside of the sheath communicate with each other; and a valve body capable of opening and closing the communicating hole. The valve body is configured to be capable of switching between a closed state in which the communicating hole is covered and blocked with the valve body and an open state which the valve body enters by being moved to the outside of the sheath from the closed state, and in which the communicating hole is open.

A urological device adapted for placement in a urethra of a user for treatment of incontinence includes a stem, an anchor portion connected to a distal end portion of the stem, a bladder retainer connected to a proximal end of the stem, and a urological valve connected to the proximal end of the stem. The urological valve includes a plurality of movable leaflets connected to and extending in a proximal direction way from the proximal end of the stem. The movable leaflets have an at-rest closed configuration adapted to prevent a flow of urine through the stem, and the movable leaflets are adapted to evert in a distal direction to provide the urological valve with an open configuration adapted to allow urine to flow through the stem.

A cannula and instrument guide assembly includes a cannula with a proximal portion and a tube. An instrument guide is removably inserted into the proximal portion of the cannula and extends through the cannula to a distal end of the tube. The proximal portion of the cannula has an insufflation port. The instrument guide provides at least one interior passageway to support a shaft of a surgical instrument that passes through the instrument guide. One or more channels on an outer surface of the instrument guide provide a passage for insufflation gas received from the insufflation port to the distal end of the tube. The one or more channels have a first cross-sectional area at a proximal end and a second, larger cross-sectional area at a distal end. The one or more channels may have the first cross-sectional area along a majority of the length of the channels.

A one-way valve can prevent reverse flow of fluids from the breast pump milk bag into the breast pump shield. The breast pump kit also can include a cover that can seal the breast pump shield, if desired.

A trocar assembly includes a trocar that includes a trocar housing and a cannula that extends distally from the trocar housing, and an integral seal system positioned within a central passageway extending axially through the trocar and engageable against a surgical tool shaft extended therethrough. The integral seal system includes an asymmetric seal and a duckbill seal arranged distal to the asymmetric seal, and the asymmetric seal defines a diaphragm that complements insertion and extraction drag forces generated by the duckbill seal against the surgical tool shaft such that total insertion and extraction drag forces generated by the integral seal system are equalized.
