    Abstract: An iris-type valve assembly for controlling a flow of fluid. The assembly comprises a base member, a rotatable member, and an elongated elastomeric valve sheath. The distal end of the valve sheath is secured to the base member and the proximal end of the valve sheath is secured to the rotatable member. At least one of the vale sheath ends includes a flange that is secured to a valve-receiving surface of the base member or the rotatable member. The base member and the rotatable member are aligned to define an elongated passageway therethrough for passage of an interventional device, and the elastomeric valve sheath is disposed along the passageway and has a longitudinal opening therethrough for passage of the interventional device. Upon rotation of the rotatable member relative to the base member the longitudinal opening of the valve sheath is selectively constrictable to comprise a seal around the interventional device. The assembly may be provided with ratcheting members to inhibit recoil of the rotatable member, and rib members along the inner surface of the valve sheath to enhance the seal provided by the assembly.

    Abstract: A hemostasis valve includes a single gland (16) with multiple offset longitudinal slits (32/34) that do no extend through the gland (16) completely. The multiple slits (32/34) from a complex pathway for the guide dilator/catheter (58) and thus a better seal. The offset slits (32/34) are joined by a lateral cut (36) in the gland. When a guide wire or dilator/catheter (58) is introduced into the introducer, the gland (16) deforms sufficiently to allow the guide wire or other device (58) to move through the first slits (32), the lateral cut (36) and the second slits (34). This complex pathway or slit provides a larger sealing surface thereby creating a better seal. As a result, effective seals may be formed around relatively large, as compared to the inner diameter of an introducer sheath, catheters.

    Abstract: A valve (10) useful as a fluid flow check valve or as a self-sealing, penetrable, hemostatic valve for sealing a catheter introducer (12) includes a seal (26) which is highly resistant to tearing and leakage, yet is capable of accepting repeated penetrations by devices of a wide variety of diameters. The seal (26) is disk-shaped and is composed of a thermoplastic styrenic elastomer, such as a styrene-ethylene/butylene-styrene block copolymer, of low durometer (a hardness of no more than about 30 Shore A). The seal (26) is preferably contained in a valve body (40) and is compressed between a valve seat (48) in the valve body (40) and a cap (56) connected to the valve body (40). The seal (26) includes at least one perforation (34) closed by such compression. This compression also provides the seal (26) with a proximal or upstream concave surface (30), making it highly resistant to inversion during repeated removals and manipulations of interventional devices passing through the valve (10). The valve (10) of the present invention is particularly advantageous in that is seals the introducer (12) with a high degree of effectiveness when no interventional device lies across its seal (26), and in that it offers a high resistance to tearing when penetrated by devices of large diameter. The valve (10) also allows the easy passage of devices without interfering with tactile feedback ("feel") from them.

    Abstract: This invention is a hemostasis cannula comprising a housing (10) having a passage (11) therethrough sized to receive a catheter and a valve body (1') mounted in the passage. The valve body (1') includes an opening (3') therethrough which forms a seal around a catheter enclosed within the cannula. When the catheter is removed, the valve body (1') closes thus blocking airflow into the patient's blood vessel, and also blocking blood flow out of the patient's blood vessel. The cannula housing (10) also includes a side port (47) for introducing fluids into the patient's blood vessel.
