    Abstract: Embodiments provide swallowable devices, preparations and methods for delivering viable cells (VC) into the GI tract including GI wall tissue or other tissue site. Particular embodiments provide a swallowable device such as a capsule for delivering VC into an intestinal wall or other site. The VC can be contained within a tissue-penetrating shell disposed in the capsule that protects the VC as they pass through the GI tract until they are inserted into GI tract tissue or other location. The shell desirably has shape, size and material consistency to be contained in a swallowable capsule, delivered from the capsule into solid tissue by the application of force on the shell and biodegrade within the solid tissue to release the VC into the tissue. Within the shell or other structure the VC can be maintained in a viability-sustaining gel that preserves the viability of the VC for selected time periods.

    Abstract: A processor comprises instructions to adjust a bias of an input signal in order to decrease a duty cycle of a pulse modulated optical signal. The bias can be increased, decreased, or maintained in response to one or more measured values of the signal. In many embodiments, a gain of the signal is adjusted with the bias in order to inhibit distortion. The bias can be adjusted slowly in order to inhibit audible noise, and the gain can be adjusted faster than the bias in order to inhibit clipping of the signal. In many embodiments, one or more of the bias or the gain is adjusted in response to a value of the signal traversing a threshold amount. The value may comprise a trough of the signal traversing the threshold.

    Abstract: Autologous bone marrow cells (BMC) are transplanted to a heterologous site in a patient after a sample of the patient's BMC has been tested and found to have a phenotypic profile which meets minimum criteria for transplantation. The phenotypic profile may be obtained by screening a sample of bone marrow cells (BMC) from the patient for the phenotypic profile, such as a CD profile, the phenotype profile may be assessed to determine the likelihood that the BMC will be suitable for transplantation to the heterologous tissue site without enriching particular phenotypic population(s) of the BMC.

    Abstract: Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents within the GI tract. Many embodiments provide a swallowable device for delivering the agents. Particular embodiments provide a swallowable device such as a capsule for delivering drugs into the intestinal wall or other GI lumen. Embodiments also provide various drug preparations that are configured to be contained within the capsule, advanced from the capsule into the intestinal wall and degrade to release the drug into the bloodstream to produce a therapeutic effect. The preparation can be operably coupled to delivery means having a first configuration where the preparation is contained in the capsule and a second configuration where the preparation is advanced out of the capsule into the intestinal wall. Embodiments of the invention are particularly useful for the delivery of drugs which are poorly absorbed, tolerated and/or degraded within the GI tract.

    Abstract: An apparatus for closing a surgical incision comprises left and right base panels, a plurality of closure components, and a plurality of left and right axial supports coupled to the respective base panels. The closure components couple the left and right base panels to each other laterally and have left and right ends coupled to the respective base panels. The closure components are positioned laterally across the left and right panels, the left axial supports are disposed between pairs of left closure component ends, the right axial supports are disposed between pairs of right closure component ends, and the left and right axial supports are offset from one another such that a serpentine arrangement of consecutive closure components and axial supports is formed. The apparatus can be made of antimicrobial materials or materials impregnated with antimicrobial agents. A flexible adhesive cover can be provided over the apparatus when in use.

    Abstract: A system for controlling urination in a patient includes an implantable controller and an external device. The implantable controller includes circuitry and electrodes for stimulating the pudenal nerves in order to control urination. In addition, the implantable controller includes sensors for determining information on bladder fullness and for transmitting such information to an external device which is used for controlling the implanted controller. The external device will display when bladder filling exceeds a safe threshold level, allowing the patient and a caregiver to take appropriate steps to allow the patient to urinate.
